| Subject | [PATCH 03/10] mfd: sun6i-prcm: Add codec analog controls sub-device for Allwinner A23 |
| Message-ID | <sCAiu-6Wb-25@gated-at.bofh.it> |
The PRCM block on the A23 contains a message box like interface to
the registers for the analog path controls of the internal codec.
Add a sub-device for it.

Use the DEVICE_RES_* macros.
