sound fixes for 3.18-rc1 Here are a collection of small fixes after 3.18 merge. The urgent one is the fix for kernel panics with linked PCM substream triggered by the recent nonatomic PCM ops support. Other two fixes (emu10k1 and bebob) are stable fixes, and one easy PCI ID addition for a new Intel HD-audio controller.

sound-3.18-rc1fd1a2a90 · ·
sound updates for 3.18-rc1 This time it's a relatively calm update batch, but the amount isn't too small in the end. Here we go over some highlights: - ALSA core - One major change is the support of nonatomic PCM operations. This allows the trigger and other callbacks to call schedule(), which would be useful for mailbox type communications. Already some drivers (Digigram ones) have been converted to use together with threaded irqs as an example. - Improvement / fixes of DSD PCM format support - HD-audio - Large volume of rewrites are found in Realtek codec driver for converting Dell and HP quirks to generic forms. - Inverted dmic code cleanup from David. - Realtek COEF access has been optimized. - Now HD-audio jack infrastructure allows multiple callbacks, which fixes / simplifies the jack-dependent power controls on STAC/IDT and VIA codecs. - Many additional device-specific fixups as usual - A few deadcode cleanups, CA0132 code cleanup, etc. - ASoC - More componentization work from Lars-Peter, this time mainly cleaning up the suspend and bias level transition callbacks. - Real system support for the Intel drivers and a bunch of fixes and enhancements for the associated CODEC drivers, this is going to need a lot quirks over time due to the lack of any firmware description of the boards. - Jack detect support for simple card from Dylan Reid. - A bunch of small fixes and enhancements for the Freescale drivers. - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32, Everest Semiconductor ES8328 and Freescale cards using the ASRC in newer i.MX processors. - A few simple-card fixes, mostly cleanups but also a fix for - interaction between GPIO 0 and simple-card. - Misc - Virtuoso / Oxygen updates by Clemens - USB-audio: Yamaha MOTIF XF MIDI port name fixes - Conversion of kernel messages to standard dev_*() in ctxfi driver. -

gpio-v3.18-1a092e19b · ·
This is the bulk of GPIO changes for the v3.18 development cycle: - Increase the default ARCH_NR_GPIO from 256 to 512. This was done to avoid having a custom <asm/gpio.h> header for the x86 architecture - GPIO is custom and complicated enough as it is already! We want to move to a radix to store the descriptors going forward, and finally get rid of this fixed array size altogether. - Endgame patching of the gpio_remove() semantics initiated by Abdoulaye Berthe. It is not accepted by the system that the removal of a GPIO chip fails during e.g. reboot or shutdown, and therefore the return value has now painfully been refactored away. For special cases like GPIO expanders on a hot-pluggable bus like USB, we may later add some gpiochip_try_remove() call, but for the cases we have now, return values are moot. - Some incremental refactoring of the gpiolib core and ACPI GPIO library for more descriptor usage. - Refactor the chained IRQ handler set-up method to handle also threaded, nested interrupts and set up the parent IRQ correctly. Switch STMPE and TC3589x drivers to use this registration method. - Add a .irq_not_threaded flag to the struct gpio_chip, so that also GPIO expanders that block but are still not using threaded IRQ handlers. - New drivers for the ARM64 X-Gene SoC GPIO controller. - The syscon GPIO driver has been improved to handle the "DSP GPIO" found on the TI Keystone 2 SoC:s. - ADNP driver switched to use gpiolib irqchip helpers. - Refactor the DWAPB driver to support being instantiated from and MFD cell (platform device). - Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP, Xilinx and Crystalcove drivers. - Various minor fixes.
