Subject: [PATCHv6 3/6] arm: dts: socfpga: Add clk-phase-sd-hs property to the sdmmc node
Date:   Wed, 26 Oct 2022 09:16:28 -0500
Message-Id: <20221026141631.696863-3-dinguyen@kernel.org>
In-Reply-To: <20221026141631.696863-1-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.
