Bluetooth: btmrvl add firmware dump support

2014-12-03T16:35:51+00:00

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

Bluetooth: btmrvl: rename definitions from 88xx to 8897

2014-09-30T12:13:29+00:00

Register offsets are different for SD8897 and newer chip SD8887.
We can not have common btmrvl_sdio_card_reg map for them.

Bluetooth: btmrvl: avoid sending data to firmware after hs_activated

2014-07-15T06:01:19+00:00

We should suspend hci device and purge remaining data in tx queue
before enabling host sleep in firmware. If any data is sent to
firmware after host sleep is activated, firmware may end up
sending a TX_DONE interrupt to driver. If this interrupt gets
delivered to host while the SDIO host controller is suspending,
it may crash the system.

Conversely, in resume handler, we should resume hci device after
host sleep is de-activated.

Bluetooth: btmrvl: use cal-data from device-tree instead of conf file

2013-12-04T13:09:03+00:00

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.

Bluetooth: Provide hdev parameter to hci_recv_frame() driver callback

2013-10-11T07:45:34+00:00

To avoid casting skb->dev into hdev, just let the drivers provide
the hdev directly when calling hci_recv_frame() function.

This patch also fixes up all drivers to provide the hdev.
