Date: Wed,  8 Dec 2021 05:22:10 +0300	[thread overview]
Message-ID: <20211208022210.1300773-3-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20211208022210.1300773-1-dmitry.baryshkov@linaro.org>

To stop disp_cc_mdss_mdp_clk_src from getting stuck during boot if it
was enabled by the bootloader, part it to the TCXO clock source.
