  • bb7f4f0bc   btmrvl: add platform specific wakeup interrupt support ... Browse Code »

    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.

  • dc759613b   Bluetooth: btmrvl add firmware dump support ... Browse Code »

    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

  • 433a9389a   Bluetooth: btmrvl: use cal-data from device-tree instead of conf file ... Browse Code »

    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.

    A text file containing calibration data in hex format can
    be provided at following path:

    /lib/firmware/mrvl/sd8797_caldata.conf

    The data will be downloaded to firmware during initialization.
