Subject: [PATCH 2/2] clk: imx: imx6ul: Fix csi clk gate register
Date: Thu, 26 Aug 2021 17:20:49 +0200	[thread overview]
Message-ID: <20210826152049.4175381-2-s.riedmueller@phytec.de> (raw)
In-Reply-To: <20210826152049.4175381-1-s.riedmueller@phytec.de>

According to the imx6ul Reference Manual the csi clk gate register is
CCM_CCGR3 (offset 0x74) bit 0/1. For the imx6ull on the other hand the
Reference Manual lists register CCM_CCGR2 (offset 0x70) bit 2/3 as the
csi clk gate which is the current setting.

Tests have shown though that the correct csi clk gate register for the
imx6ull is actually CCM_CCGR3 bit 0/1 as well. Thus set the correct
register for both platforms.
