Modify the bandwidth calculation logic to support 12Mhz, 6Mhz with different frame sizes. Vijendar Mukunda (2): soundwire: amd: add clock init control function soundwire: amd: refactor bandwidth calculation logic Changes since v5: - change the 'divider' variable from signed to unsigned - drop dev_dbg() logs in clock init control function - change few variables(stream_slot_size, max_slots, next_offset) from signed to unsigned in compute port parameters callback. Changes since v4: - update commit message Changes since v3: - drop unnecessary debug logs. Changes since v2: - Update commit message - add comments in the code. Changes since v1: - Update Cover letter title. - Fix typo error in commit message. - drop unnecessary condition check in compute params callback. drivers/soundwire/amd_manager.c | 100 ++++++++++++++++++++++++++---- drivers/soundwire/amd_manager.h | 4 -- include/linux/soundwire/sdw_amd.h | 4 ++ 3 files changed, 93 insertions(+), 15 deletions(-) -- 2.45.2
