| | | * ASoC: da7219: Fix pole orientation detection on certain headsetsAdam Thomson2022-05-301-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been recently found that certain 'active' headsets can be mis-detected as OMTP instead of CTIA, causing obvious issus with audio quality. This relates to increased resistances which negatively impacts the pole detection circuitry within the device. To counter this, ground switches on both headphone channels are available to enable/disable and these allow for the detection process to operate as intended, even with active headsets. This commit adds control of the ground switches to the AAD logic.

| | * | ASoC: Intel: avs: Fix build error on arc, m68k and sparcUwe Kleine-König2022-05-301-1/+2
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some platforms (i.e. arc, m68k and sparc) __fls returns an int (while on most platforms it returns an unsigned long). This triggers a format warning on these few platforms as the driver uses %ld to print a warning. So explicitly cast the return value to unsigned long to make the warning go away (and so fix allmodconfig build on the affected architectures).

Other devices define a chip like this but seem only half-implemented, not really handling battery charging etc. This patch switches the Toshiba MFD device to provide GPIO descriptors to the battery charger and SoC codec. As a result some descriptors need to be moved out of the Tosa boardfile and new one added: all SoC GPIO resources to these drivers now comes from the main boardfile, while the MFD provide GPIOs for its portions. As a result we can request one GPIO from our own GPIO chip and drop two hairy callbacks into the board file. This platform badly needs to have its drivers split up and converted to device tree probing to handle this quite complex relationship in an orderly manner. I just do my best in solving the GPIO descriptor part of the puzzle. Please don't ask me to fix everything that is wrong with these driver to todays standards, I am just trying to fix one aspect. I do try to use modern devres resource management and handle deferred probe using new functions where appropriate.

Currently the dtrace is 'open managed' regardless of IPC version (we do force disable it for IPC4, but the dtrace calls remain in place). From the kernel point of view there are only few ops that needs to be exposed by the firmware tracing support and everything else is IPC private, should not be known by the core. This series converts the current dma-trace as ipc3 specific firmware tracing sub-component and moves all private data out from generic code.

And the power consumption is listed below 1. amp off and 'pwdnn' high => idle state, PVDD = 1mA, DVDD = 7mA 2. amp off and 'pwdnn' low => shutdown state, PVDD < 20uA, DVDD < 15uA It's the large difference for the consumption current This fix is to use pm_runtime and regcache to handle 'pwdnn' gpio control.
