* drivers: mfd: fix audio mute issue after ADSP SSRVidyakumar Athota2017-01-17
| | | | | | | | | | | Native audio playback is muted after adsp subsystem restart, because codec device_reset() API is called even before device_down() API finishes execution. This causes audio to mute, as codec is not in proper reset state. Add new lock to synchronize codec subsystem restart APIs.

| * ASoC: wcd: modify tasha version check macrosYeleswarapu Nagaradhesh2016-09-15
| | | | | | | | | | | | | | | | | | | | TASHA_IS_1_1 macro checks only for version number. This macro returns true for tavil codec. So modify tasha macros to check for codec and version.

* | ASoC: wcd934x: Add codec version check for wcd934xWalter Yang2016-09-14
|/ | | | | | | | | As there are many hardware version of wcd934x codec. Add version check in the code so that userspace can get the version info. CRs-Fixed: 1063367 Change-Id: Ia320380d568426c2d7a414a832980a556ff27f0f Signed-off-by: Walter Yang <yandongy@codeaurora.org>
* mfd: wcd9xxx: Reduce irqsoff latencyPhani Kumar Uppalapati2016-08-25
| | | | | | | | | | | | WCD9XXX irq driver uses device tree APIs in the IRQ handler. Device tree APIs disable interrupts for the duration of their execution. Do not use these APIs in the wcd9xxx irq handler to reduce the interrupt off (irqsoff) latency.

| | | | | | | | | | | | | | | | | | | | | | | | Depending on the impedance across HPHL and HPHR, set classh configurations so as to avoid false OCP events. Move wcd9xxx_registers.h to uapi folder, as this header file is used by userspace for wdc9330 codec.
