Merge tag 'at91-cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91 into next/soc
Merge "at91: cleanup for 3.20 #2" from Nicolas Ferre: Second batch of cleanup for 3.20: - By reworking the PM code, we can remove the AT91 more specific initialization - We are using DT for SRAM initialization now, so we can remove its explicit mapping - The PMC clock driver now hosts IDLE function for at91rm9200 with other SoCs ones. * tag 'at91-cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91: (37 commits) ARM: at91: move at91rm9200_idle() to clk/at91/pmc.c ARM: at91: remove unused at91_init_sram ARM: at91: sama5d4: remove useless call to at91_init_sram ARM: at91: remove useless map_io ARM: at91: pm: prepare for multiplatform ARM: at91: pm: add UDP and UHP checks to newer SoCs ARM: at91: pm: use the mmio-sram pool to access SRAM ARM: at91: pm: rework cpu detection ARM: at91: dts: sama5d3: add ov2640 camera sensor support ARM: at91: dts: sama5d3: change name of pinctrl of ISI_MCK ARM: at91: dts: sama5d3: change name of pinctrl_isi_{power,reset} ARM: at91: dts: sama5d3: move the isi mck pin to mb ARM: at91: dts: sama5d3: add missing pins of isi ARM: at91: dts: sama5d3: split isi pinctrl ARM: at91: dts: sama5d3: add isi clock ARM: at91/dt: ethernut5: use at91sam9xe.dtsi ARM: at91/dt: Add a dtsi for at91sam9xe ARM: at91/dt: add SRAM nodes ARM: at91/dt: at91rm9200ek: enable RTC ARM: at91/dt: rm9200: add RTC node ...

ARM Atmel SoCs (aka AT91)
|
||||
=========================
|
||||
|
||||
|
||||
Introduction
|
||||
------------
|
||||
This document gives useful information about the ARM Atmel SoCs that are
|
||||
currently supported in Linux Mainline (you know, the one on kernel.org).
|
||||
|
||||
It is important to note that the Atmel | SMART ARM-based MPU product line is
|
||||
historically named "AT91" or "at91" throughout the Linux kernel development
|
||||
process even if this product prefix has completely disappeared from the
|
||||
official Atmel product name. Anyway, files, directories, git trees,
|
||||
git branches/tags and email subject always contain this "at91" sub-string.
|
||||
|
||||
|
||||

Linux kernel information
|
||||
------------------------
|
||||
Linux kernel mach directory: arch/arm/mach-at91
|
||||
MAINTAINERS entry is: "ARM/ATMEL AT91RM9200 AND AT91SAM ARM ARCHITECTURES"
|
||||
|
||||
|
||||
Device Tree for AT91 SoCs and boards
|
||||
------------------------------------
|
||||
All AT91 SoCs are converted to Device Tree. Since Linux 3.19, these products
|
||||
must use this method to boot the Linux kernel.
|
||||
|
||||
Work In Progress statement:
|
||||
Device Tree files and Device Tree bindings that apply to AT91 SoCs and boards are
|
||||
considered as "Unstable". To be completely clear, any at91 binding can change at
|
||||
any time. So, be sure to use a Device Tree Binary and a Kernel Image generated from
|
||||
the same source tree.
|
||||
Please refer to the Documentation/devicetree/bindings/ABI.txt file for a
|
||||
definition of a "Stable" binding/ABI.
|
||||
This statement will be removed by AT91 MAINTAINERS when appropriate.
|
||||
|
||||
Naming conventions and best practice:
|
||||
- SoCs Device Tree Source Include files are named after the official name of
|
||||
the product (at91sam9g20.dtsi or sama5d33.dtsi for instance).
|
||||
- Device Tree Source Include files (.dtsi) are used to collect common nodes that can be
|
||||
shared across SoCs or boards (sama5d3.dtsi or at91sam9x5cm.dtsi for instance).
|
||||
When collecting nodes for a particular peripheral or topic, the identifier have to
|
||||
be placed at the end of the file name, separated with a "_" (at91sam9x5_can.dtsi
|
||||
or sama5d3_gmac.dtsi for example).
|
||||
- board Device Tree Source files (.dts) are prefixed by the string "at91-" so
|
||||
that they can be identified easily. Note that some files are historical exceptions
|
||||
to this rule (sama5d3[13456]ek.dts, usb_a9g20.dts or animeo_ip.dts for example).
