Xinming Hu bb7f4f0bce btmrvl: add platform specific wakeup interrupt support
On some arm-based platforms, we need to configure platform specific
parameters by device tree node and also define our node as a child
node of parent SDIO host controller.
This patch parses these parameters from device tree. It includes
calibration data download to firmware, wakeup pin configured to firmware,
and soc specific wake up gpio, which will be set as wakeup interrupt pin.

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
         fi
 done

Bing Zhao 433a9389a1 Bluetooth: btmrvl: use cal-data from device-tree instead of conf file
Some ARM versions of Chromebook need to download a new calibration
data from host driver to firmware. They do have EEPROM but still
need a piece of new calibration data in test mode.

The cal-data is platform dependent. It's simpler and more feasible
to use device tree based cal-data instead of configuration file
based cal-data.

This patch remove configuration file based cal-data downloading
and replace it using cal-data from device tree.

When CONFIG_OF is not selected, or the specific property is not
present in the device tree, the calibration downloading will not
happen.

works only on 32-bit system. It will crash the 64-bit system.
Replace "u32" with "unsigned long" to fix this issue.

Marcel Holtmann dcf47f3bc7 Bluetooth: Fix complicated assignment of firmware for Marvell devices
The Marvell Bluetooth SDIO driver has a really complicated concept on how
firmware names are assigned to specific device ids. Fix that by doing a
proper structure and assign it to the module device table.

And while at it fix various coding style weirdness that is still present
in this driver.

Marcel Holtmann 944fe798c6 Bluetooth: Remove pointless ifdef protection for Marvell header files
Both header files of the Marvell Bluetooth driver are private anyway and
if the driver happens to include them twice or they create a circular

ifdefs.
