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.
