ASoC: Updates for v3.15

Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:

 - Lots of cleanups from Takashi for enumerations; the original API for
   these was error prone so he's refactored lots of code to use more
   modern APIs which avoid issues.
 - Elimination of the ASoC level wrappers for I2C and SPI moving us
   closer to converting to regmap completely and avoiding some
   randconfig hassle.
 - Provide both manually and transparently locked DAPM APIs rather than
   a mix of the two fixing some concurrency issues.
 - Start converting CODEC drivers to use separate bus interface drivers
   rather than having them all in one file helping avoid dependency
   issues.
 - DPCM support for Intel Haswell and Bay Trail platforms.
 - Lots of work on improvements for simple-card, DaVinci and the Renesas
   rcar drivers.
 - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
   CSR SiRF SoC.

+STMicroelectronics SoC DWMAC glue layer controller
+
+The device node has following properties.
+
+Required properties:
+ - compatible   : Can be "st,stih415-dwmac", "st,stih416-dwmac" or
+   "st,stid127-dwmac".
+ - reg          : Offset of the glue configuration register map in system
+   configuration regmap pointed by st,syscon property and size.
+
+ - reg-names    : Should be "sti-ethconf".
+
+ - st,syscon    : Should be phandle to system configuration node which
+   encompases this glue registers.
+
+ - st,tx-retime-src: On STi Parts for Giga bit speeds, 125Mhz clocks can be
+   wired up in from different sources. One via TXCLK pin and other via CLK_125
+   pin. This wiring is totally board dependent. However the retiming glue
+   logic should be configured accordingly. Possible values for this property
+
+           "txclk" - if 125Mhz clock is wired up via txclk line.
+           "clk_125" - if 125Mhz clock is wired up via clk_125 line.
+
+   This property is only valid for Giga bit setup( GMII, RGMII), and it is
+   un-used for non-giga bit (MII and RMII) setups. Also note that internal
+   clockgen can not generate stable 125Mhz clock.
+
+ - st,ext-phyclk: This boolean property indicates who is generating the clock
+  for tx and rx. This property is only valid for RMII case where the clock can
+  be generated from the MAC or PHY.
+
+ - clock-names: should be "sti-ethclk".
+ - clocks: Should point to ethernet clockgen which can generate phyclk.

+
+And for each spcified driver, there could be one .of_xlate_tdm_slot_mask()

+
+For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit
