Subject: [PATCH mvebu v2 03/10] clk: mvebu: armada-37xx-periph: remove .set_parent method for CPU PM clock
Date: Thu, 14 Jan 2021 13:40:25 +0100 [thread overview]
Message-ID: <20210114124032.12765-4-pali@kernel.org> (raw)
In-Reply-To: <20210114124032.12765-1-pali@kernel.org>
From: Marek Behún <kabel@kernel.org>
Remove the .set_parent method in clk_pm_cpu_ops.
This method was supposed to be needed by the armada-37xx-cpufreq driver,
but was never actually called due to wrong assumptions in the cpufreq
driver. After this was fixed in the cpufreq driver, this method is not
needed anymore.
