[PATCH linux dev-4.7 v2 3/3] ARM: dts: aspeed-g5: Give pinctrl phandles for gfx and lhc

[Andrew Jeffery]

The g5's pinctrl reported:

[    0.750000] aspeed-g5-pinctrl 1e6e2000.syscon:pinctrl at 1e6e2000: No GFX phandle found, some mux configurations may fail
[    0.750000] aspeed-g5-pinctrl 1e6e2000.syscon:pinctrl at 1e6e2000: No LHC phandle found, some mux configurations may fail

as the aspeed,external-nodes property was missing from the pinctrl
node. Fix the mux capability by adding the required phandles in the
AST2500-based board files, as the AST2520 from the g5 family doesn't
have a GFX IP block.

The commit is *very* loosely based on b590c8d2eed5748dfe52c4fc13df6cadb1b56d58
in the ARM next/dt tree.

Since v1:

* Push assignment of phandles to the aspeed,external-nodes property out to the
  board dts. I expect eventually we'll want to do this in an ast2500.dtsi
