Subject: [PATCHv4 2/3] arm64: dts: socfpga: Add clk-phase-sd-hs property to the sdmmc node
Date: Wed, 28 Sep 2022 11:54:19 -0500	[thread overview]
Message-ID: <20220928165420.1212284-2-dinguyen@kernel.org> (raw)
In-Reply-To: <20220928165420.1212284-1-dinguyen@kernel.org>

The sdmmc controller's CIU(Card Interface Unit) clock's phase can be
adjusted through the register in the system manager. Add the binding
"altr,sysmgr-syscon" to the SDMMC node for the driver to access the
system manager. Add the "clk-phase-sd-hs" property in the SDMMC node to
designate the smpsel and drvsel properties for the CIU clock.

Signed-off-by: Dinh Nguyen <dinguyen@kernel.org>
---
v4: no change
v3: removed unnecessary property in "altr,sysmgr-syscon"
