a2dp hw: adding a2dp tuning through bdroid_buildcfg.h
This adds possibility to configure a2dp tuning on an
arbitrary sysfs path and arbitrary ON/OFF values.
It's activated when a2dp is being used, and
deactivates when a2dp is stopped.
This way a device can either use an a2dp_tuning sysfs file
or cpu scaling min freq sysfs path with a target
min_freq value for elevation.
Here are two example of the two strategies of usage for
this:
bdroid_buildcfg.h - sysfs tuning file
#define A2DP_HW_SYSFS_TUNER "/sys/devices/platform/tegra_uart.2/a2dp_tuning"
#define A2DP_HW_SYSFS_TUNER_OFF "0"
#define A2DP_HW_SYSFS_TUNER_ON "1"
bdroid_buildcfg.h - scaling min freq file
#define A2DP_HW_SYSFS_TUNER "/sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq"
#define A2DP_HW_SYSFS_TUNER_OFF "0"
#define A2DP_HW_SYSFS_TUNER_ON "204000"
