[PATCH v1] ASoC: cs35l41: Update DSP1RX5/6 Sources for DSP config
by Stefan Binding 12 Apr '24

12 Apr '24

Currently, all ASoC systems are set to use VPMON for DSP1RX5_SRC, however, this is required only for internal boost systems. External boost systems require VBSTMON instead of VPMON to be the input to DSP1RX5_SRC. Shared Boost Active acts like Internal boost (requires VPMON). Shared Boost Passive acts like External boost (requires VBSTMON) All systems require DSP1RX6_SRC to be set to VBSTMON.

[PATCH] slimbus: Convert to platform remove callback returning void
by Uwe Kleine-König 11 Apr '24

11 Apr '24

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert the slimbus drivers from always returning zero in the remove callback to the void returning variant.

[PATCH v1 0/7] Add features, fixes and laptops for CS35L41 HDA
by Stefan Binding 11 Apr '24

11 Apr '24

This chain adds a number of improvements for CS35L41, including a new firmware loading feature, as well as some additional cleanup. Patch 1 adds support for a new firmware tuning file which is used to set special tuning parameters used by the firmware. The HP Omen laptop added in patches 2 and 3 use such a feature. Patch 4 changes the DSP1RX5/6 Source used by the firmware to depend on the boost type. A similar change in the ASoC driver will be needed later. Patches 5 and 6 are cleanup patches, with the first of those re-using cs-amp-lib for calibration which as added for CS35L56 drivers, ensuring that all laptops are using the correct calibration values. Patch 7 fixes a small error in the CS35L41 Property table for the Lenovo Legion slim 7 16ARHA7.
