Subject: [PATCH v3 1/3] ARM: dts: exynos: Add assigned clock parent to CMU in Exynos3250
Date: Sun, 6 Sep 2020 16:21:44 +0200 [thread overview]
Message-ID: <20200906142146.21266-1-krzk@kernel.org> (raw)
Commit 52005dece527 ("ARM: dts: Add assigned clock parents to CMU node
for exynos3250") added assigned clocks under Clock Management Unit to
fix hangs when accessing ISP registers.
However the dtschema expects "clocks" property if "assigned-clocks" are
used. Add reference to input clock, the parent used in
"assigned-clock-parents" to silence the dtschema warnings:
arch/arm/boot/dts/exynos3250-artik5-eval.dt.yaml: clock-controller@10030000: 'clocks' is a dependency of 'assigned-clocks'
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

Changes since v2:
1. Use XUSBXTI as real input clock.
Changes since v1:
1. Add clocks property.
This is a v2 for:
