Subject: [PATCH] ti-st: Enhange logging for Shared Transport - TI driver
From: Alexandra Sava <alexandrasava18@...il.com>
* added new module parameter named debug_mask to control displayed
messages verbosity
* the logging mechanism is enabled via CONFIG_TI_ST_DEBUG Kconfig option
Signed-off-by: Alexandra Sava <alexandrasava18@...il.com>
