Arnd Bergmann 7841d06e43 Bluetooth: bpa10x: fix BT_HCIUART dependency
The change to bpa10x to use the h4_recv_buf helper added a dependency
on BT_HCIUART. This was incorrectly added to Kconfig by adding a
'select' statement, which now in turn causes build failures
when CONFIG_TTY is not set:

warning: (BT_HCIBPA10X) selects BT_HCIUART which has unmet direct dependencies (NET && BT && TTY)
vers/built-in.o: In function `hci_uart_tty_receive':
fpga-mgr.c:(.text+0x282824): undefined reference to `tty_unthrottle'
drivers/built-in.o: In function `hci_uart_tty_ioctl':
fpga-mgr.c:(.text+0x282aa0): undefined reference to `n_tty_ioctl_helper'
drivers/built-in.o: In function `hci_uart_flush':

This replaces the 'select BT_HCIUART' dependency with 'depends on', which
does not have this kind of problem. Alternatively, one could add 'depends
on TTY', but avoiding 'select' on user-visible options is generally the
preferred choice as that does not introduce the potential for dependency
loops or incomplete dependency chains.

Marcel Holtmann 9148991924 Bluetooth: bpa10x: Fix missing BT_HCIUART dependency
Selecting just BT_HCIUART_H4 is not enough and it also needs to select
BT_HCIUART to avoid this warning:

warning: (BT_HCIBPA10X) selects BT_HCIUART_H4 which has unmet direct
dependencies (NET && BT && BT_HCIUART)

Marcel Holtmann 943cc59219 Bluetooth: bpa10x: Use h4_recv_buf helper for frame reassembly
The manually coded frame reassembly is actually broken. The h4_recv_buf
helper from the UART driver is a perfect fit for frame reassembly for
this driver. So just export that function and use it here as well.

Loic Poulain d06f107bcd Bluetooth: btintel: Add iBT register access over HCI support
Add regmap ibt to support Intel Bluetooth silicon register access
over HCI. Intel BT/FM combo chip allows to read/write some registers
(e.g. FM registers) via its HCI interface.

Read/Write operations are performed via a HCI transaction composed of
a HCI command (host->controller) followed by a HCI command complete
event (controller->host). Read/Write Command opcodes can be specified
to the regmap init function.
We define data formats which are intel/vendor specific.

Register Read/Write HCI command payload (Host):
Field: | REG ADDR | MODE | DATA_LEN | DATA... |
size:  |   32b    |  8b  |    8b    |  8b*    |

Register Read HCI command complete event payload (Controller):
Field: | CMD STATUS | REG ADDR | DATA... |
size:  |     8b     |   32b    |  8b*    |

Register Write HCI command complete event payload (Controller):
Field: | CMD_STATUS |
size:  |     8b     |

Since this payload is HCI encapsulated, Little Endian byte order is
used.

Write/Read Example:

If we write 0x0000002a at address 0x00008c04, with opcode_write 0xfc5d,
The resulting transaction is (btmon trace):

< HCI Command (0x3f|0x005d) plen 10 [hci0]
        04 8c 00 00 02 04 2a 00 00 00
> HCI Event (0x0e) plen 4
      Unknown (0x3f|0x005d) ncmd 1
        00

Then, if we read the same register with opcode_read 0xfc5e:

< HCI Command (0x3f|0x005e) plen 6 [hci0]
        04 8c 00 00 02 04
> HCI Event (0x0e) plen 12 [hci0]
      Unknown (0x3f|0x005e) ncmd 1
        00 04 8c 00 00 2a 00 00 00

Loic Poulain ca93cee5a5 Bluetooth: hci_uart: Add basic support for Intel Lightning Peak devices
The Intel Lightning Peak devices do not come with Bluetooth firmware
loaded and thus require a full download of the operational Bluetooth
firmware when the device is attached via the Bluetooth line discipline.

Lightning Peak devices start with a bootloader mode that only accepts
a very limited set of HCI commands. The supported commands are enough
to identify the hardware and select the right firmware to load.

Xinming Hu dc759613b0 Bluetooth: btmrvl add firmware dump support
This patch adds firmware dump support for marvell
bluetooth chipset. Currently only SD8897 is supported.
This is implemented based on dev_coredump, a new mechnism
introduced in kernel 3.18rc3

Firmware dump can be trigger by
echo 1 > /sys/kernel/debug/bluetooth/hci*/config/fw_dump
and when the dump operation is completed, data can be read by
cat /sys/class/devcoredump/devcd*/data

We have prepared following script to divide fw memory
dump data into multiple files based on memory type.

 [root]# cat btmrvl_split_dump_data.sh
 #!/bin/bash
 # usage: ./btmrvl_split_dump_data.sh dump_data

 fw_dump_data=$1

 mem_type="ITCM DTCM SQRAM APU CIU ICU MAC EXT7 EXT8 EXT9 EXT10 EXT11 EXT12 EXT13 EXTLAST"

 for name in ${mem_type[@]}
 do
         sed -n "/Start dump $name/,/End dump/p" $fw_dump_data  > tmp.$name.log
         if [ ! -s tmp.$name.log ]
                 then
                         rm -rf tmp.$name.log
                 else
                         # Remove the describle info "Start dump" and "End dump"
                         sed '1d' tmp.$name.log | sed '$d' > /data/$name.log
                         if [ -s /data/$name.log ]
                         then
                                 echo "generate /data/$name.log"
                         else
                                 sed '1d' tmp.$name.log | sed '$d' > /var/$name.log
                                 echo "generate /var/$name.log"
                         fi
                         rm -rf tmp.$name.log
