[PATCH] ARM: imx6: fix GK802 DT

[PATCH] ARM: imx6: fix GK802 DT

[Philipp Zabel]

From: Philipp Zabel <philipp.zabel@gmail.com>

Including "imx6q.dtsi" after <arm/imx6q-gk802.dts> also includes
<arm/imx6ql.dtsi> again, disabling all peripherals, including the
serial console uart. We can't include it first either, because
arm/imx6q-gk802.dts contains the /dts-v1/ header.
This patch drops the offending include statement and instead adds
the missing IPU aliases manually.

Alternatively you could remove the line

	#include <arm/imx6q.dtsi>

from arch/arm/dts/imx6q.dtsi, right? This is already included via

arch/arm/dts/imx6q-gk802.dts -> #include <arm/imx6q-gk802.dts>
dts/src/arm/imx6q-gk802.dts -> #include "imx6q.dtsi"

anyhow. This would need a fixup for all imx6q boards that don't have a
dts in dts/src though (i.e. all but imx6q-gk802 if my grep magic was
correct).

Best regards
Uwe
