Fixes for SM7150 dispcc driver

[PATCH 0/3] Fixes for SM7150 dispcc driver

Posted by Jens Reidel 4 months, 3 weeks ago

The MDSS needs a reference to the MDSS_CORE reset since 6.17-rc,
otherwise video mode panel initialization appears to be broken.

Also ensure that the parent of dispcc_mdss_pclk0_clk_src gets prepared
and enabled to fix an "rcg didn't update its configuration" warning that
started occurring recently.
