Subject: [PATCH v8 04/12] clk: tegra20: Use custom CCLK implementation
Date: Thu, 19 Mar 2020 22:02:21 +0300	[thread overview]
Message-ID: <20200319190229.32200-5-digetx@gmail.com> (raw)
In-Reply-To: <20200319190229.32200-1-digetx@gmail.com>

We're going to use the generic cpufreq-dt driver on Tegra20 and thus CCLK
intermediate re-parenting will be performed by the clock driver. There is
now special CCLK implementation that supports all CCLK quirks, this patch
makes Tegra20 SoCs to use that implementation.
