Subject: [PATCH 1/4] arm64: dts: rk3399-u-boot: Delete vop assigned-clocks/rates
Date: Thu, 23 Jan 2020 21:58:42 +0530	[thread overview]
Message-ID: <20200123162845.10651-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20200123162845.10651-1-jagan-dyjBcgdgk7Pe9wHmmfpqLFaTQe2KTcn/@public.gmane.org>

Linux supporting assigned-clocks for VOP on rk3399 by assuming
U-Boot not initializing it on this linux commit:

commit <617f4472bdd3> ("arm64: dts: rockchip: init rk3399 vop clock rates")

There is no specific need to initialize these assigned clock
in U-Boot as video drivers still work with default aclk and  
hclk values. So, these clocks are simply not supported by rk3399
clock driver.

But, during stdio probe of vidconsole, the device probe
will try to check whether the assigned clocks on that video
console node is initialized or not? and return error if not.

So, delete these property via -u-boot dtsi as there is
no specific need in U-Boot.
