Subject: [PATCH 10/10] staging: fsl-mc: dprc: drop unused APIs
From: Laurentiu Tudor <laurentiu.tudor@....com>
Leave only APIs that area actually used in the bus driver.
The patch is mostly mechanical, with a couple exceptions:
- getters/setters were not removed even if only one of
them is being used
- versioning API was also left in place
They will be added back on an as-needed basis.
Signed-off-by: Laurentiu Tudor <laurentiu.tudor@....com>
