Subject: [PATCH v1 2/2] clk: qcom: dispcc: Remove support of disp_cc_mdss_rscc_ahb_clk
Date: Tue, 11 Feb 2020 17:43:56 +0530	[thread overview]
Message-ID: <1581423236-21341-2-git-send-email-tdas@codeaurora.org> (raw)
In-Reply-To: <1581423236-21341-1-git-send-email-tdas@codeaurora.org>

The disp_cc_mdss_rscc_ahb_clk is default enabled from hardware and thus
does not require to be marked CRITICAL. This which would allow the RCG to
be turned OFF when the display turns OFF and not blocking XO.
