Commit Message

Liu Ying Dec. 7, 2020, 3:20 a.m. UTC 
This patch adds bindings for i.MX8qxp/qm Display Prefetch Resolve Gasket.

Signed-off-by: Liu Ying <victor.liu@nxp.com>
---
Note that this depends on the 'two cell binding' clock patch set which has
already landed in Shawn's i.MX clk/imx git branch.  Otherwise, imx8-lpcg.h
won't be found.

v2->v3:
* No change.

v1->v2:
* Use new dt binding way to add clocks in the example.

Use enum instead of oneOf+const.
