[PATCH AUTOSEL 5.6 47/79] ASoC: rsnd: Fix "status check failed" spam for multi-SSI
by Sasha Levin 30 Apr '20

From: Matthias Blankertz <matthias.blankertz(a)cetitec.com> [ Upstream commit 54cb6221688660670a2e430892d7f4e6370263b8 ] Fix the rsnd_ssi_stop function to skip disabling the individual SSIs of a multi-SSI setup, as the actual stop is performed by rsnd_ssiu_stop_gen2 - the same logic as in rsnd_ssi_start. The attempt to disable these SSIs was harmless, but caused a "status check failed" message to be printed for every SSI in the multi-SSI setup. The disabling of interrupts is still performed, as they are enabled for all SSIs in rsnd_ssi_init, but care is taken to not accidentally set the EN bit for an SSI where it was not set by rsnd_ssi_start.

[PATCH AUTOSEL 5.6 46/79] ASoC: rsnd: Don't treat master SSI in multi SSI setup as parent
by Sasha Levin 30 Apr '20

30 Apr '20

From: Matthias Blankertz <matthias.blankertz(a)cetitec.com> [ Upstream commit 0c258657ddfe81b4fc0183378d800c97ba0b7cdd ] The master SSI of a multi-SSI setup was attached both to the RSND_MOD_SSI slot and the RSND_MOD_SSIP slot of the rsnd_dai_stream. This is not correct wrt. the meaning of being "parent" in the rest of the SSI code, where it seems to indicate an SSI that provides clock and word sync but is not transmitting/receiving audio data. Not treating the multi-SSI master as parent allows removal of various special cases to the rsnd_ssi_is_parent conditions introduced in commit a09fb3f28a60 ("ASoC: rsnd: Fix parent SSI start/stop in multi-SSI mode"). It also fixes the issue that operations performed via rsnd_dai_call() were performed twice for the master SSI. This caused some "status check failed" spam when stopping a multi-SSI stream as the driver attempted to stop the master SSI twice.
