Subject: [PATCH 6.1.y-cip 08/10] clk: vc3: Fix output clock mapping
Date: Wed, 22 Nov 2023 14:31:54 +0000	[thread overview]
Message-ID: <20231122143156.204055-9-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20231122143156.204055-1-biju.das.jz@bp.renesas.com>

commit 6dcf03bcac31dec528867180f96580652fc3ac5b upstream.

According to Table 3. ("Output Source") in the 5P35023 datasheet,
the output clock mapping should be 0=REF, 1=SE1, 2=SE2, 3=SE3,
4=DIFF1, 5=DIFF2. But the code uses inverse. Fix this mapping issue.
