From mboxrd@z Thu Jan 1 00:00:00 1970 From: rmk+kernel@armlinux.org.uk (Russell King) Date: Tue, 16 May 2017 14:45:30 +0100 Subject: [PATCH] arm64: dts: marvell: mcbin: add sdhci Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add sdhci support for MACCHIATOBin boards. This uses the AP806 SDHCI for eMMC and CP110 master for the SD card slot. Signed-off-by: Russell King --- This version labels up the uSD connector, adds the vqmmc regulator for the uSD (the regulator itself already present in the DT), and supports the card detect signal. For eMMC, this version adds the vqmmc regulator, which again is already present in the DT, marks it as not supporting SD or SDIO, and also includes "slow mode" since testing with previous versions of the driver have shown that selecting faster speeds results in errors. arch/arm64/boot/dts/marvell/armada-8040-mcbin.dts | 23 ++++++++++++++++++++++ 1 file changed, 23 insertions(+) diff --git a/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dts b/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dts index cc167e05941a..60111ed3234a 100644 --- a/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dts +++ b/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dts @@ -95,6 +95,21 @@ status = "okay"; }; +&ap_sdhci0 { + bus-width = <8>; + /* + * Not stable in HS modes - phy needs "more calibration", so add + * the "slow-mode" and disable SDR104, SDR50 and DDR50 modes. + */ + marvell,xenon-phy-slow-mode; + no-1-8-v; + no-sd; + no-sdio; + non-removable; + status = "okay"; + vqmmc-supply = <&v_vddo_h>; +}; + &cpm_i2c0 { clock-frequency = <100000>; status = "okay"; @@ -105,6 +120,14 @@ status = "okay"; }; +&cpm_sdhci0 { + /* U6 */ + broken-cd; + bus-width = <4>; + status = "okay"; + vqmmc-supply = <&v_3_3>; +}; + &cpm_usb3_0 { /* J38? - USB2.0 only */ status = "okay"; -- 2.7.4
