Subject: [PATCH] clk: sunxi-ng: v3s: Fix TCON reset de-assert bit
Date: Tue, 22 Jan 2019 09:16:19 +0100 [thread overview]
Message-ID: <20190122081619.27653-1-paul.kocialkowski@bootlin.com> (raw)
According to the datasheet and the reference code from Allwinner, the
bit used to de-assert the TCON reset is bit 4, not bit 3.
Fix it in the V3s CCU driver.
