-Subject: [PATCH 173/226] staging: fsl-mc: get version of root dprc from MC
- hardware
-
-The root dprc is discovered as a platform device in the device tree. The
-version of that dprc was previously set using hardcoded values from the API
-header in the kernel). This patch removes the use of the hardcoded version
-numbers and instead reads the actual dprc version from the hardware.
