The second argument to a .set_sysclk() op is a clk_id, not a stream index, so it is incorrect to compare it with SNDRV_PCM_STREAM_PLAYBACK. Technically this code works correctly anyway because SNDRV_PCM_STREAM_PLAYBACK is defined as 0, which is also the clk_id for the mclk_tx as enforced by the device tree bindings. So this is a formal error, not triggering incorrect behaviour. 2. The else branch will consider any nonzero value as "rx", while only value 1 should be allowed for the mclk_rx clock. This does trigger incorrect behaviour if passing clk_id not equal to 0 or 1. Fix problem 1 by adding a new enum for the clock indexes as enforced in device tree and replace accordingly: * stream -> clk_id * SNDRV_PCM_STREAM_PLAYBACK -> CLK_MCLK_TX (value 0) Fix problem 2 by adding an 'else if' and returning error if clk_id is not 0 or 1.

List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=archiver.kernel.org@lists.infradead.org From: Luca Ceresoli The Rockchip RK3308 8-channel I2S adapter has a mainline driver that can work fine with an audio-graph-card or simple-audio-card. Those card drivers call the .set_sysclk op once, and this is usually enough for applications using an external codec. But in reality the I2S adapter has two clock inputs (TX and RX), and the preferred way to use the RK3308 internal codec is enabling both clocks, potentially with different rates. The existing simple-card code does not implement this possibility. To allow setting both clocks, add a new minimal driver that builds on top of audio-graph-card and changes the dai_link->init callback with a modified version of asoc_simple_init_dai(). This ultimately calls the set_sysclk() callback as many times as the number of clocks defined in device tree. With this implementation, the same rate is set to all the sysclks. Setting different rates can be added later.
