[PATCH v2] soundwire: bandwidth allocation: Use hweight32() to calculate set bits
by Richard Fitzgerald 16 Mar '23

16 Mar '23

Replace the call to sdw_ch_mask_to_ch() with a call to hweight32(). sdw_ch_mask_to_ch() is counting the number of set bits. The hweight() family of functions already do this, and they have an advantage of using a bit-counting instruction if it is available on the target CPU. This also fixes a potential infinite loop bug in the implementation of sdw_ch_mask_to_ch().

Miscellaneous updates to make the example match reality: - Correct SSI resource region size, - Complete half-conversion to new-style CPG/MSSR bindings, - Add missing power-domains, resets, and reset-names properties, - Use interrupt binding definitions instead of hardcoded numbers, - Correct interrupt flags, - Drop double blank line.

[PATCH 0/2] soundwire: bus: Prevent infinite loop in sdw_ch_mask_to_ch()
by Richard Fitzgerald 15 Mar '23

15 Mar '23

sdw_ch_mask_to_ch() would loop forever if bit 31 of the mask was set. The entire function is unnecessary because the existing standard function hweight32() already does the same thing, and hweight32() is safe. But the change has been made in two steps.

[PATCH 0/7] Add the Lantiq PEF2256 audio support
by Herve Codina 15 Mar '23

15 Mar '23

Hi, This series adds support for audio using the Lantiq PEF2256 framer. The Lantiq PEF2256 is a framer and line interface component designed to fulfill all required interfacing between an analog E1/T1/J1 line and the digital PCM system highway/H.100 bus. The first part of this series (patches 1 to 4) adds the Lantiq PEF2256 driver core. The second part (patches 5 to 7) adds the audio support using the Lantiq PEF2256 driver core. The consumer/provider relation between the codec and the driver core allows to use the PEF2256 framer for other purpose than audio support.
