[PATCH v2] ARM: dts: sun5i: Move display blocks to sun5i.dtsi
Hans de Goede
hdegoede at redhat.com
Thu Jun 9 03:54:15 PDT 2016
All sun5i models share the same die, so the display-engine is
identical, except for which outputs / encoders are available.
All models support parallel / lvds lcd panels, the R8 and A10s also
support tv-out and the A10s also supports HDMI out.
This commit prepares for enabling display blocks on A10s boards,
but it also is a bug-fix for A10s boards, because before this commit
the simplefb nodes for A10s were not listing the recently added
pll3 as clock, causing the display to go black when the kernel
disables unused clocks at the end of boot.
