Fix Agera PLL config of CAMCC for SM6350 & SM7150

[PATCH 0/2] Fix Agera PLL config of CAMCC for SM6350 & SM7150

Posted by Luca Weiss 3 months, 2 weeks ago

On SM6350 I noticed that CAMCC_MCLK* refuses to turn on (being stuck on
off). The cause seems that PLL2 (of type Agera) is not configured
correctly due to the implementation in clk-alpha-pll.c differing between
downstream (e.g. msm-4.19) and upstream, and therefore the USER_CTL
value is not configured.

While looking around, it looks like camcc-sm7150.c has exactly the same
issue, so fix that one as well.
