Subject: [PATCHv5 3/6] arm: dts: socfpga: Add clk-phase-sd-hs property to the sdmmc node
Date: Wed, 19 Oct 2022 12:06:54 -0500 [thread overview]
Message-ID: <20221019170657.68014-4-dinguyen@kernel.org> (raw)
In-Reply-To: <20221019170657.68014-1-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.
