[PATCH v5 0/4] Add CS35L41 shared boost feature

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Valve's Steam Deck uses CS35L41 in shared boost mode, where both speakers
share the boost circuit.
Add this support in the shared lib, but for now, shared boost is not
supported in HDA systems as would require BIOS changes.

Based on David Rhodes shared boost patches.

Also, fix boost config overwriting in IRQ found in the review and do a
small refactor of the code.

Changes from V4:
 - Fix Document subject

Changes from V3:
 - Fix wrong code sent
 - Fix ISO C90 mixed declarations and code 

Changes from V2:
 - Drop External boost without VSPK Documentation
 - Move Shared boost to use values 2 and 3
 - Revert back to reg_sequence but reading the value first and only update
the necessary bits
 - Fix bug found by Intel kernel Test Robot

Changes from V1:
 - Fix Documentation patch subject
 - New patch for External boost without VSPK Documentation
 - New patch to fix boost IRQ overwriting issue
 - New patch to refactor IRQ release error code
 - reinit_completion on pcm_startup
 - fix DRE switch overwriting
 - return IRQ_HANDLED in PLL_LOCK case
