soundwire: debugfs: Switch to sdw_read_no_pm

2023-01-09T16:16:27Z

It is rather inefficient to be constantly playing with the runtime PM reference for each individual register, switch to holding a PM runtime reference across the whole register output.

soundwire: debugfs: use controller id and link_id for debugfs

2021-10-01T04:23:47Z

link_id can be zero and if we have multiple controller instances in a system like Qualcomm debugfs will end-up with duplicate namespace resulting in incorrect debugfs entries. Using bus-id and link-id combination should give a unique debugfs directory entry and should fix below warning too. "debugfs: Directory 'master-0' with parent 'soundwire' already present!"

soundwire: add debugfs support

2019-08-23T06:31:02Z

Add base debugfs mechanism for SoundWire bus by creating soundwire root and master-N and slave-x hierarchy. Also add SDW Slave SCP, DP0 and DP-N register debug file. Registers not implemented will print as "XX" Credits: this patch is based on an earlier internal contribution by Vinod Koul, Sanyog Kale, Shreyas Nc and Hardik Shah.
