Subject: [PATCH 4/6] dts: rk3288: support for dedicating npll to a vop
|
||
|
|
|
||
|
|
This patch is taken from Urja Rannikko ( @urjaman ) patchset here :
|
||
|
|
https://github.com/urjaman/arch-c201/blob/master/linux-c201/0020-RK3288-HDMI-clock-hacks-combined.patch
|
||
|
|
https://www.spinics.net/lists/arm-kernel/msg673156.html
|
||
|
|
|
||
|
|
The original description was :
|
||
|
|
|
||
|
|
Add the VOP DCLKs to the assigned clocks list so their
|
||
|
|
parents can be set in the dts include files for
|
||
|
|
devices that do dedicate npll to a vop.
