Subject: [PATCH v4 02/19] clk: tegra: Change CLK_M_DIV clocks to OSC_DIV clocks
Date: Tue, 17 Dec 2019 12:03:49 -0800 [thread overview]
Message-ID: <1576613046-17159-3-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1576613046-17159-1-git-send-email-skomatineni@nvidia.com>
Tegra has no CLK_M_DIV2 and CLK_M_DIV4 clocks from CLK_M and instead
it has OSC_DIV2 and OSC_DIV4 clocks from OSC pads.
This patch removes CLK_M_DIV2 and CLK_M_DIV4 fixed clocks and adds
OSC_DIV2 and OSC_DIV4 fixed clocks with OSC as parent for Tegra30
through Tegra210 clock drivers.
