Subject: [PATCH] clk: ti: dra7xx: Reset the mcasp3_ahclkx_mux clock value
Date: Wed, 6 Sep 2017 16:06:39 +0530	[thread overview]
Message-ID: <1504694199-32227-1-git-send-email-j-keerthy@ti.com> (raw)

Reset the mcasp3_ahclkx_mux to abe_24m_fclk. This is needed
in case of kexec where the reset values might be wiped off.
