Merge tag 'asoc-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linussound-4.12-rc1
ASoC: Updates for v4.12 A quiet release for the core, but lots of new drivers this time around: - A new, generalized, API for hooking up jacks which makes it easier to write generic machine drivers for simple cases. - Continuing fixes for issues with the x86 CPU drivers. - New drivers for Cirrus CS35L35, DIO DIO2125, Everest ES7132, HiSilicon hi6210, Maxim MAX98927, MT2701 systems with WM8960, Nuvoton NAU8824, Odroid systems, ST STM32 SAI controllers and x86 systems with DA7213

+STMicroelectronics STM32 Serial Audio Interface (SAI).
+
+The SAI interface (Serial Audio Interface) offers a wide set of audio protocols
+as I2S standards, LSB or MSB-justified, PCM/DSP, TDM, and AC'97.
+The SAI contains two independent audio sub-blocks. Each sub-block has
+its own clock generator and I/O lines controller.
+
+Required properties:
+ - compatible: Should be "st,stm32f4-sai"
+ - reg: Base address and size of SAI common register set.
+ - clocks: Must contain phandle and clock specifier pairs for each entry
+ in clock-names.
+ - clock-names: Must contain "x8k" and "x11k"
+ "x8k": SAI parent clock for sampling rates multiple of 8kHz.
+ "x11k": SAI parent clock for sampling rates multiple of 11.025kHz.
+ - interrupts: cpu DAI interrupt line shared by SAI sub-blocks
+
+Optional properties:
+ - resets: Reference to a reset controller asserting the SAI
+
+SAI subnodes:
+Two subnodes corresponding to SAI sub-block instances A et B can be defined.
+Subnode can be omitted for unsused sub-block.
+
+SAI subnodes required properties:
+ - compatible: Should be "st,stm32-sai-sub-a" or "st,stm32-sai-sub-b"
+ for SAI sub-block A or B respectively.
+ - reg: Base address and size of SAI sub-block register set.
+ - clocks: Must contain one phandle and clock specifier pair
+ for sai_ck which feeds the internal clock generator.
+ - clock-names: Must contain "sai_ck".
+ - dmas: see Documentation/devicetree/bindings/dma/stm32-dma.txt
+ - dma-names: identifier string for each DMA request line
+ "tx": if sai sub-block is configured as playback DAI

+ * unsigned long pa_memcpy(void *dstp, const void *srcp, unsigned long len)
+ *
+ * Inputs:
+ * - sr1 already contains space of source region
+ * - sr2 already contains space of destination region
+ *
+ * Returns:
+ * - number of bytes that could not be copied.
+ * On success, this will be zero.
+ *
+ * This code is based on a C-implementation of a copy routine written by
+ * Randolph Chung, which in turn was derived from the glibc.
+ *
+ * Several strategies are tried to try to get the best performance for various
+ * conditions. In the optimal case, we copy by loops that copy 32- or 16-bytes
+ * at a time using general registers. Unaligned copies are handled either by
+ * aligning the destination and then using shift-and-write method, or in a few
+ * cases by falling back to a byte-at-a-time copy.
+ *
+ * Testing with various alignments and buffer sizes shows that this code is
+ * often >10x faster than a simple byte-at-a-time copy, even for strangely
+ * aligned operands. It is interesting to note that the glibc version of memcpy
+ * (written in C) is actually quite fast already. This routine is able to beat
+ * it by 30-40% for aligned copies because of the loop unrolling, but in some
+ * cases the glibc version is still slightly faster. This lends more
+ * credibility that gcc can generate very good code as long as we are careful.
+ *
+ * Possible optimizations:
+ * - add cache prefetching
+ * - try not to use the post-increment address modifiers; they may create
+ * additional interlocks. Assumption is that those were only efficient on old
+ * machines (pre PA8000 processors)
