README on the ADC/Touchscreen Controller
|
|
||||||
========================================
|
|
||||||
|
|
||||||
The LH79524 and LH7A404 include a built-in Analog to Digital
|
|
||||||
controller (ADC) that is used to process input from a touchscreen.
|
|
||||||
The driver only implements a four-wire touch panel protocol.
|
|
||||||
|
|
||||||
The touchscreen driver is maintenance free except for the pen-down or
|
|
||||||
touch threshold. Some resistive displays and board combinations may
|
|
||||||
require tuning of this threshold. The driver exposes some of its
|
|
||||||
internal state in the sys filesystem. If the kernel is configured
|
|
||||||
with it, CONFIG_SYSFS, and sysfs is mounted at /sys, there will be a
|
|
||||||
directory
|
|
||||||
|
|
||||||
/sys/devices/platform/adc-lh7.0
|
|
||||||
|

The threshold is the current touch threshold. It defaults to 750 on
|
|
||||||
most targets.

||||||
|
|
||||||

threshold. Values outside of this range will be silently ignored.

|
||||||
|
|
||||||
# cat threshold_range
|
|
||||||
0 1023
|
|
||||||
|
|
||||||
To change the threshold, write a value to the threshold file.

|
||||||
|
|
||||||
# echo 500 > threshold
|
|
||||||
# cat threshold
|
|
||||||

|
|
||||||
|
|
||||||
The samples file contains the most recently sampled values from the
|
|
||||||
ADC. There are 12. Below are typical of the last sampled values when
|
|
||||||
the pen has been released. The first two and last two samples are for
|
|
||||||
detecting whether or not the pen is down. The third through sixth are
|
|
||||||
X coordinate samples. The seventh through tenth are Y coordinate
|
|
||||||
samples.

README on the Compact Flash for Card Engines
|
|
||||||
============================================
|
|
||||||
|
|
||||||
There are three challenges in supporting the CF interface of the Card
|
|
||||||
Engines. First, every IO operation must be followed with IO to
|
|
||||||
another memory region. Second, the slot is wired for one-to-one
|
|
||||||
address mapping *and* it is wired for 16 bit access only. Second, the
|
|
||||||
interrupt request line from the CF device isn't wired.
|
|
||||||
|
|
||||||
The IOBARRIER issue is covered in README.IOBARRIER. This isn't an
|
|
||||||
onerous problem. Enough said here.
|
|
||||||
|
|
||||||
The addressing issue is solved in the
|
|
||||||
arch/arm/mach-lh7a40x/ide-lpd7a40x.c file with some awkward
|
|
||||||
work-arounds. We implement a special SELECT_DRIVE routine that is
|
|
||||||
called before the IDE driver performs its own SELECT_DRIVE. Our code
|
|
||||||
recognizes that the SELECT register cannot be modified without also
|
|
||||||
writing a command. It send an IDLE_IMMEDIATE command on selecting a
|
|
||||||
drive. The function also prevents drive select to the slave drive
|
|
||||||
since there can be only one. The awkward part is that the IDE driver,
|
|
||||||
even though we have a select procedure, also attempts to change the
|
|
||||||
drive by writing directly the SELECT register. This attempt is
|
|
||||||
explicitly blocked by the OUTB function--not pretty, but effective.
|
|
||||||
|
|
||||||
The lack of interrupts is a more serious problem. Even though the CF
|
|
||||||
card is fast when compared to a normal IDE device, we don't know that
|
|
||||||
the CF is really flash. A user could use one of the very small hard
|
|
||||||
drives being shipped with a CF interface. The IDE code includes a
|
|
||||||
check for interfaces that lack an IRQ. In these cases, submitting a
|
|
||||||
command to the IDE controller is followed by a call to poll for
|
|
||||||
completion. If the device isn't immediately ready, it schedules a
|
|
||||||
timer to poll again later.

README on the IOBARRIER for CardEngine IO
|
|
||||||
=========================================
|
|
||||||
|
|
||||||
Due to an unfortunate oversight when the Card Engines were designed,
|
|
||||||
the signals that control access to some peripherals, most notably the
|
|
||||||
SMC91C9111 ethernet controller, are not properly handled.
|
|
||||||
|
|
||||||
The symptom is that some back to back IO with the peripheral returns
|
|
||||||
unreliable data. With the SMC chip, you'll see errors about the bank
|
|
||||||
register being 'screwed'.
|
|
||||||
|
|
||||||
The cause is that the AEN signal to the SMC chip does not transition
|
|
||||||
for every memory access. It is driven through the CPLD from the CS7
|
|
||||||
line of the CPU's static memory controller which is optimized to
|
|
||||||
eliminate unnecessary transitions. Yet, the SMC requires a transition
|
|
||||||
for every write access. The Sharp website has more information about
|
|
||||||
the effect this power-conserving feature has on peripheral
|
|
||||||
interfacing.
|
|
||||||
|
|
||||||
The solution is to follow every write access to the SMC chip with an
|
|
||||||
access to another memory region that will force the CPU to release the
|
|
||||||
chip select line. It is important to guarantee that this access
|
|
||||||
forces the CPU off-chip. We map a page of SDRAM as if it were an
|
|
||||||
uncacheable IO device and read from it after every SMC IO write
|
|
||||||
operation.
|
|
||||||
|
|
||||||
SMC IO
|
|
||||||
BARRIER IO
|
|
||||||
|
|
||||||
Only this sequence is important. It does not matter that there is no
|
|
||||||
BARRIER IO before the access to the SMC chip because the AEN latch
|
|
||||||
only needs occurs after the SMC IO write cycle. The routines that
|
|
||||||
implement this work-around make an additional concession which is to
|
|
||||||
disable interrupts during the IO sequence. Other hardware devices
|
|
||||||
(the LogicPD CPLD) have registers in the same physical memory
|
|
||||||
region as the SMC chip. An interrupt might allow an access to one of
|
|
||||||
those registers while SMC IO is being performed.
|
|
||||||
|
|
||||||
You might be tempted to think that we have to access another device
|
|
||||||
attached to the static memory controller, but the empirical evidence
|
|
||||||
indicates that this is not so. Mapping 0x00000000 (flash) and
|
|
||||||
0xc0000000 (SDRAM) appear to have the same effect. Using SDRAM seems
|
|
||||||
to be faster. Choosing to access an undecoded memory region is not
|
|
||||||
desirable as there is no way to know how that chip select will be used
|
|
||||||
in the future.

README on the LCD Panels
|
|
||||||
========================
|
|
||||||
|
|
||||||
Configuration options for several LCD panels, available from Logic PD,
|
|
||||||
are included in the kernel source. This README will help you
|
|
||||||
understand the configuration data and give you some guidance for
|
|
||||||
adding support for other panels if you wish.
|
|
||||||
|
|
||||||
|
|
||||||
lcd-panels.h
|
|
||||||
------------
|
|
||||||
|
|
||||||
There is no way, at present, to detect which panel is attached to the
|
|
||||||
system at runtime. Thus the kernel configuration is static. The file
|
|
||||||
arch/arm/mach-ld7a40x/lcd-panels.h (or similar) defines all of the
|
|
||||||
panel specific parameters.
|
|
||||||
|
|
||||||
It should be possible for this data to be shared among several device
|
|
||||||
families. The current layout may be insufficiently general, but it is
|
|
||||||
amenable to improvement.
|
|
||||||
|
|
||||||
|
|
||||||
PIXEL_CLOCK
|
|
||||||
-----------
|
|
||||||
|
|
||||||
The panel data sheets will give a range of acceptable pixel clocks.
|
|
||||||
The fundamental LCDCLK input frequency is divided down by a PCD
|
|
||||||
constant in field '.tim2'. It may happen that it is impossible to set
|
|
||||||
the pixel clock within this range. A clock which is too slow will
|
|
||||||
tend to flicker. For the highest quality image, set the clock as high
|
|
||||||
as possible.
|
|
||||||
|
|
||||||
|
|
||||||
MARGINS
|
|
||||||
-------
|
|
||||||
|
|
||||||
These values may be difficult to glean from the panel data sheet. In
|
|
||||||
the case of the Sharp panels, the upper margin is explicitly called
|
|
||||||
out as a specific number of lines from the top of the frame. The
|
|
||||||
other values may not matter as much as the panels tend to
|
|
||||||
automatically center the image.
|
|
||||||
|
|
||||||
|
|
||||||
Sync Sense
|
|
||||||
----------
|
|
||||||
|
|
||||||
The sense of the hsync and vsync pulses may be called out in the data
|
|
||||||
sheet. On one panel, the sense of these pulses determine the height
|
|
||||||
of the visible region on the panel. Most of the Sharp panels use
|
|
||||||
negative sense sync pulses set by the TIM2_IHS and TIM2_IVS bits in
|
|
||||||
'.tim2'.

each red and blue and 6 bits of green.

README on the SDRAM Controller for the LH7a40X
|
|
||||||
==============================================
|
|
||||||
|
|
||||||
The standard configuration for the SDRAM controller generates a sparse
|
|
||||||
memory array. The precise layout is determined by the SDRAM chips. A
|
|
||||||
default kernel configuration assembles the discontiguous memory
|
|
||||||
regions into separate memory nodes via the NUMA (Non-Uniform Memory
|
|
||||||
Architecture) facilities. In this default configuration, the kernel
|
|
||||||
is forgiving about the precise layout. As long as it is given an
|
|
||||||
accurate picture of available memory by the bootloader the kernel will
|
|
||||||
execute correctly.
|
|
||||||
|
|
||||||
The SDRC supports a mode where some of the chip select lines are
|
|
||||||
swapped in order to make SDRAM look like a synchronous ROM. Setting
|
|
||||||
this bit means that the RAM will present as a contiguous array. Some
|
|
||||||
programmers prefer this to the discontiguous layout. Be aware that
|
|
||||||
may be a penalty for this feature where some some configurations of
|
|
||||||
memory are significantly reduced; i.e. 64MiB of RAM appears as only 32
|
|
||||||
MiB.
|
|
||||||
|
|
||||||
There are a couple of configuration options to override the default
|
|
||||||
behavior. When the SROMLL bit is set and memory appears as a
|
|
||||||
contiguous array, there is no reason to support NUMA.
|
|
||||||
CONFIG_LH7A40X_CONTIGMEM disables NUMA support. When physical memory
|
|
||||||
is discontiguous, the memory tables are organized such that there are
|
|
||||||
two banks per nodes with a small gap between them. This layout wastes
|
|
||||||
some kernel memory for page tables representing non-existent memory.
|
|
||||||
CONFIG_LH7A40X_ONE_BANK_PER_NODE optimizes the node tables such that
|
|
||||||
there are no gaps. These options control the low level organization
|
|
||||||
of the memory management tables in ways that may prevent the kernel
|
|
||||||
from booting or may cause the kernel to allocated excessively large
|
|
||||||
page tables. Be warned. Only change these options if you know what
|
|
||||||
you are doing. The default behavior is a reasonable compromise that

will suit all users.

README on the Vectored Interrupt Controller of the LH7A404
|
|
||||||
==========================================================
|
|
||||||
|
|
||||||
The 404 revision of the LH7A40X series comes with two vectored
|
|
||||||
interrupts controllers. While the kernel does use some of the
|
|
||||||
features of these devices, it is far from the purpose for which they
|
|
||||||
were designed.
|
|
||||||
|
|
||||||
When this README was written, the implementation of the VICs was in
|
|
||||||
flux. It is possible that some details, especially with priorities,
|
|
||||||
will change.
|
|
||||||
|
|
||||||
The VIC support code is inspired by routines written by Sharp.
|
|
||||||
|
|
||||||
|
|
||||||
Priority Control
|
|
||||||
----------------
|
|
||||||
|
|
||||||
The significant reason for using the VIC's vectoring is to control
|
|
||||||
interrupt priorities. There are two tables in
|
|
||||||
arch/arm/mach-lh7a40x/irq-lh7a404.c that look something like this.
|
|
||||||
|
|
||||||
static unsigned char irq_pri_vic1[] = { IRQ_GPIO3INTR, };
|
|
||||||
static unsigned char irq_pri_vic2[] = {
|
|
||||||
IRQ_T3UI, IRQ_GPIO7INTR,
|
|
||||||
IRQ_UART1INTR, IRQ_UART2INTR, IRQ_UART3INTR, };
|
|
||||||
|
|
||||||
The initialization code reads these tables and inserts a vector
|
|
||||||
address and enable for each indicated IRQ. Vectored interrupts have
|
|
||||||
higher priority than non-vectored interrupts. So, on VIC1,
|
|
||||||
IRQ_GPIO3INTR will be served before any other non-FIQ interrupt. Due
|
|
||||||
to the way that the vectoring works, IRQ_T3UI is the next highest
|
|
||||||
priority followed by the other vectored interrupts on VIC2. After
|
|
||||||
that, the non-vectored interrupts are scanned in VIC1 then in VIC2.
|
|
||||||
|
|
||||||
|
|
||||||
ISR
|
|
||||||
---
|
|
||||||
|
|
||||||
The interrupt service routine macro get_irqnr() in
|
|
||||||
arch/arm/kernel/entry-armv.S scans the VICs for the next active
|
|
||||||
interrupt. The vectoring makes this code somewhat larger than it was
|
|
||||||
before using vectoring (refer to the LH7A400 implementation). In the
|
|
||||||
case where an interrupt is vectored, the implementation will tend to
|
|
||||||
be faster than the non-vectored version. However, the worst-case path
|
|
||||||
is longer.
|
|
||||||
|
|
||||||
It is worth noting that at present, there is no need to read
|
|
||||||
VIC2_VECTADDR because the register appears to be shared between the
|
|
||||||
controllers. The code is written such that if this changes, it ought
|
|
||||||
to still work properly.
|
|
||||||
|
|
||||||
|
|
||||||
Vector Addresses
|
|
||||||
----------------
|
|
||||||
|
|
||||||
The proper use of the vectoring hardware would jump to the ISR
|
|
||||||
specified by the vectoring address. Linux isn't structured to take
|
|
||||||
advantage of this feature, though it might be possible to change
|
|
||||||
things to support it.
|
|
||||||
|
|
||||||
In this implementation, the vectoring address is used to speed the
|
|
||||||
search for the active IRQ. The address is coded such that the lowest
|
|
||||||
6 bits store the IRQ number for vectored interrupts. These numbers
|
|
||||||
correspond to the bits in the interrupt status registers. IRQ zero is
|
|
||||||
the lowest interrupt bit in VIC1. IRQ 32 is the lowest interrupt bit
|
|
||||||
in VIC2. Because zero is a valid IRQ number and because we cannot
|
|
||||||
detect whether or not there is a valid vectoring address if that
|
|
||||||
address is zero, the eigth bit (0x100) is set for vectored interrupts.
|
|
||||||
The address for IRQ 0x18 (VIC2) is 0x118. Only the ninth bit is set
|
|
||||||
for the default handler on VIC1 and only the tenth bit is set for the
|
|
||||||
default handler on VIC2.
|
|
||||||
|
|
||||||
In other words.
|
|
||||||
|
|
||||||
0x000 - no active interrupt

0x1ii - vectored interrupt 0xii
