[PATCH v3] ASoC: cs42xx8-i2c.c: add module device table for of
by Peter Bergin 01 Nov '22

01 Nov '22

When trying to connect the device with the driver through device-tree it is not working. The of_device_id is defined in cs42xx8.c but is not correctly included in cs42xx8-i2c.c. Move of_device_id table to cs42xx8-i2c.c. Get cs42xx8_driver_data in cs42xx8_i2c_probe() and pass as argument to cs42xx8_probe(). Move error check if no driver data found to cs42xx8_i2c_probe().

[PATCH] ALSA: hda: clarify comments on SCF changes
by Pierre-Louis Bossart 01 Nov '22

01 Nov '22

The commit 1f9d3d98694b1 ("ALSA: hda - set intel audio clock to a proper value") added a number of misleading comments. There is no ability to detect if an SCF value was set or not, what the code does is prevent the use of the 6MHz audio clock represented by the value 0 in LCTL.SCF. Changing the SCF settings does require the link to be power-cycled, but in all other cases the link is powered automatically when exiting reset. In other words, the power-cycle is an exception to the rule that the HDaudio legacy driver does not need to program SPA/CPA bits. In addition, the SCF related changes are only relevant for the first link. No functionality change, only comment clarifications.

[PATCH v1 0/3] ASoC: jz4740-i2s: Remove .set_sysclk() & friends

31 Oct '22

A quick series to get rid of .set_sysclk() from jz4740-i2s. It wasn't used in practice so this shouldn't be troublesome for anyone, and fortunately there aren't any backward compatibility concerns. The actual rationale for removing it, as opposed to fixing the issues of the current DT bindings and implementation, is provided in the dt-bindings patch. Note the last patch only applies cleanly on top of my earlier jz4740-i2s cleanup series, but doesn't strictly depend on it.
