Subject: [PATCH] clk: rockchip: rk3399: Set hardcoded clock rates same as
|
|
devicetree
|
|
|
|
Update hardcoded RK3399 clock rate definitions to match those in its
|
|
devicetree (rk3399.dtsi), based on clock-controller assigned-clocks.
|
|
Add and initialize NPLL since it's on that list, though nothing seems to
|
|
use it in the driver so far.
|
|
|
|
Also update VOP ACLK to 400MHz as it divides from CPLL (now 800MHz).
|
|
All this stops the displayed vendor bitmap from getting disfigured
|
|
when chainloading U-Boot from coreboot+depthcharge (as RW_LEGACY).
|
|
