2016-09-26mmc: sd: Export SD Status via “ssr” device attributeUri Yanai
The SD Status register contains several important fields related to the SD Card proprietary features. Those fields may be used by user space applications for vendor specific usage. None of those fields are exported today by the driver to user space. In this patch, we are reading the SD Status register and exporting (using MMC_DEV_ATTR) the SD Status register to the user space.

2016-09-26mmc: pwrseq-simple: Add an optional post-power-on-delayHans de Goede

2016-09-26dt: bindings: Make compatible optional for mmc function nodesHans de Goede
On some boards (android tablets) different batches use different sdio wifi modules. This is not a problem since mmc/sdio is an enumerable bus, so we only need to describe and activate the mmc controller in dt and then the kernel will automatically load the right driver. Sometimes it is useful to specify certain ethernet properties for these "unknown" sdio devices, specifically we want the boot-loader to be able to set "local-mac-address" as some of these sdio wifi modules come without an eeprom / without a factory programmed mac address. Since the exact device is unknown (differs per batch) we cannot use a wifi-chip specific compatible, thus sometimes it is desirable to have a mmc function node, without having to make up an otherwise unused compatible for the node, so make the compatible property optional.

2016-09-26mmc: sunxi: sun4i / sun5i do not have sample clocksHans de Goede
It turns out that sun4i (A10) and sun5i (A13 & co) do not have sample clocks, so add a new sun7i-a20-mmc compatible and do not try to use sample clocks on sun4i / sun5i. Since sun4i / sun5i do not have sample clocks, they cannot (reliably) do DDR rates, so only set MMC_CAP_1_8V_DDR when we do have sample clks. Note this patch leaves the clk_prepare_enable() / clk_disable_unprepare() calls to the sample clks as-is, without adding checks for them being NULL. All the clk_foo calls accept a NULL clk and will return success when called with a NULL clk.

tlv320dac31xx is a subset of tlv320aic31xx: - it does not have MIC inputs and ADC, thus capture is not supported, - it has analog inputs AIN1/AIN2 that can be mixed into output. Although tlv320dac31xx does work with tlv320aic31xx driver, this setup does register non-existent widgets and non-existent capture stream. Thus userspace lists non-existent objects in user interfaces, an can access these, causing operations with device registers that are declared as "reserved" in tlv320dac31xx datasheet. This patch fixes this situation by separating controls/widgets/routes into common, aic31xx-specific, and dac31xx-specific parts. Only parts that match actual hardware (as declared in "compatible" device tree property) are registered. Changes from v1: - update device tree binding documentation, - rebased on top of "ASoC: codec duplicated callback function goes to component on tlv320aic31xx" commit.

2016-09-26spi: pxa2xx: Add support for GPIO descriptor chip selectsMika Westerberg
The driver uses custom chip_info coming from platform data for chip selects implemented as GPIOs. If the system lacks board files setting up the platform data, it is not possible to use GPIOs as chip selects. This adds support for GPIO descriptors so that regardless of the underlying firmware interface (DT, ACPI or platform data) the driver can request GPIOs used as chip selects and configure them accordingly. The custom chip_info GPIO support is still left there to make sure the existing systems keep working as expected.

2016-09-26ASoC: wm_adsp: Allow preloader to do the final shutdown of the DSPCharles Keepax
The booting process for the DSP is clearly separated into two parts, the preloader brings up the core and downloads code, then the main widget starts the code actually executing. However the shutdown sequence is all handled with the main widget. To allow the preloading to be run independently of the main audio bring up it makes sense, and is generally just cleaner, for the preloader widget to shutdown those things it initialised. This patch moves the appropriate parts of the shutdown process into the preloader widget.
