From mboxrd@z Thu Jan 1 00:00:00 1970 From: dinguyen@altera.com (dinguyen at altera.com) Date: Mon, 4 Nov 2013 14:36:03 -0600 Subject: [PATCHv2 2/4] arm: dts: Add a system manager compatible property In-Reply-To: <1383597364-25613-1-git-send-email-dinguyen@altera.com> References: <1383597364-25613-1-git-send-email-dinguyen@altera.com> Message-ID: <1383597364-25613-3-git-send-email-dinguyen@altera.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Dinh Nguyen The "altr,sysmgr-sdmmc-sdr" compatible property is used for the SOCFPGA clk-sysmgr driver. This property represents the register inside the system manager that controls the clock phase of the SD/MMC driver. Also add "syscon" to the system manager node.
