[alsa-devel] [PATCH v8 0/2] Add freescale S/PDIF CPU DAI and machine drivers

[Nicolin Chen]

Changelog:
v7->v8:
 * Revised DT binding doc.
 * Revised dev_err() error msg.
 * Check return value of clk_set_rate().
v6->v7:
 * Removed extra comma in array.
 * Revised some comments.
 * Added some dev_err().
 * Check the return value of soft reset.
 * Use bitrev8() instead of extra reverse_bits().
 * Use cache_bypass as default for regmap.
v5->v6:
 * Sorted out rxtx clk source in DT binding.
 * Use devm_xxxx() functions.
 * Use platform_get_resource() instead.
v4->v5:
 * Dropped rx/tx-clksrc-names DT bindings.
 * Use standard clock binding instead to pass the clock source list.
 * Update the compatible list by using "imx35", the first SoC that has spdif.
v3->v4:
 * Use regmap for CPU DAI driver.
 * Use individual clock source for 32KHz, 44KHz, 48KHz playback.
 * Determine clock source configuration from 'clocks' entry.
 * Added imx53 to compatible list, merged imx6q and imx6dl in the list.
 * Improve the algorism of reverse_bits().
 * Dropped the unneeded clk_put().
v2->v3:
 * Removed a wrong tag from the commit of patch-1.
v1->v2:
 * Dropped one applied patch for spdif dummy codec drivers.
 * Use generic DMA DT binding.
 * Let spdif controller driver calculate the clock div.
 * Added one optional clock source for spdif tx.
 * Reivsed documentation accordingly.
