[alsa-devel] [PATCH v2 00/17] new locomo driver set
by Dmitry Eremin-Solenikov 13 May '15

13 May '15

Sharp Zaurus SL-5500 and SL-5600 use special companion Gate Array. With this patchset I tried to modernise and restructure the LoCoMo drivers. * Use platform bus and mfd core code * Use GPIO API instead of custom locomo GPIO code * Use irqdomains to manage IRQs * Split mixed locomolcd driver to lcd and backlight parts * Implement IRQ handling in GPIO driver * Implement SPI driver used as a host for mmc_spi device to control SD cards V1 was submitted about a half of a year ago. Major changes: * Use gpiod_* in most of places * Use regmap for accessing registers instead of manual RMW cycles * Split dac driver from core module to i2c bus and separate IIO driver * Replaced mdelay() calls with usleep_range or msleep where it was suitable * Rewrote SPI driver to use core transfer_one() interface

It's possible you have separate headphone and microphone jacks but I really expect microphone and button to be on the same socket.

Is it not possible to extend simple card to handle your use cases? Given the very generic naming and the fact that things like jack detection and so on should depend on the CODEC and board usually rather than on the SoC it doesn't sound like this is Rockchip specific. This also looks like you're reimplementing some device model enumeration stuff which probably shouldn't be happening but let's understand the problem you're trying to solve here before going too far into the code.

[alsa-devel] [PATCH 1/4] ASoC: wm8960: Let wm8960 driver configure its bit clock and frame clock
by Zidan Wang 12 May '15

wm8960 codec driver missing configure its bit clock and frame clock for codec master mode, so add support for it. It will calculate a appropriate frequency dividing ratio according to the system clock, bit clock and frame clock, then set the corresponding registers.

[alsa-devel] [PATCH 1/5] ASoC: wm8996: Pass the IRQF_ONESHOT flag
