Subject: [PATCH 5.1 110/155] ARM: dts: imx7d: Specify IMX7D_CLK_IPG as "ipg" clock to SDMA
Date: Thu, 13 Jun 2019 10:33:42 +0200 [thread overview]
Message-ID: <20190613075659.130595423@linuxfoundation.org> (raw)
In-Reply-To: <20190613075652.691765927@linuxfoundation.org>
[ Upstream commit 412b032a1dc72fc9d1c258800355efa6671b6315 ]
Since 25aaa75df1e6 SDMA driver uses clock rates of "ipg" and "ahb"
clock to determine if it needs to configure the IP block as operating
at 1:1 or 1:2 clock ratio (ACR bit in SDMAARM_CONFIG). Specifying both
clocks as IMX7D_CLK_SDMA results in driver incorrectly thinking that
ratio is 1:1 which results in broken SDMA funtionality. Fix the code
to specify IMX7D_CLK_IPG as "ipg" clock for SDMA, to avoid detecting
incorrect clock ratio.
