Until now the workaround for this +problem has been for overlays to clone non-removable nodes without +the offending property, but this involves a lot of unnecessary +replication. Instead, add a clone of the mmc node with non-removable +already set to the base DTB, selecting the required version using +the status properties. + +Signed-off-by: Phil Elwell <phil@raspberrypi.org> +--- + arch/arm/boot/dts/bcm2708-rpi-0-w.dts | 4 +-- + arch/arm/boot/dts/bcm2708-rpi.dtsi | 3 +- + arch/arm/boot/dts/bcm270x.dtsi | 13 ++++++++ + arch/arm/boot/dts/bcm2710-rpi-3-b-plus.dts | 5 ++-- + arch/arm/boot/dts/bcm2710-rpi-3-b.dts | 5 ++-- + arch/arm/boot/dts/overlays/mmc-overlay.dts | 7 +++++ + arch/arm/boot/dts/overlays/sdio-overlay.dts | 33 +++++++-------------- + 7 files changed, 38 insertions(+), 32 deletions(-) + +--- a/arch/arm/boot/dts/bcm2708-rpi-0-w.dts ++++ b/arch/arm/boot/dts/bcm2708-rpi-0-w.dts +@@ -14,6 +14,7 @@ + aliases { + serial0 = &uart1; + serial1 = &uart0; ++ mmc1 = &mmcnr; + }; + }; + +@@ -73,10 +74,9 @@ + }; + }; + +-&mmc { ++&mmcnr { + pinctrl-names = "default"; + pinctrl-0 = <&sdio_pins>; +- non-removable; + bus-width = <4>; + status = "okay"; + }; +--- a/arch/arm/boot/dts/bcm2708-rpi.dtsi ++++ b/arch/arm/boot/dts/bcm2708-rpi.dtsi +@@ -118,7 +118,8 @@ + sd_force_pio = <&sdhost>,"brcm,force-pio?"; + sd_pio_limit = <&sdhost>,"brcm,pio-limit:0"; + sd_debug = <&sdhost>,"brcm,debug"; +- sdio_overclock = <&mmc>,"brcm,overclock-50:0"; ++ sdio_overclock = <&mmc>,"brcm,overclock-50:0", ++ <&mmcnr>,"brcm,overclock-50:0"; + axiperf = <&axiperf>,"status"; + }; + }; +--- a/arch/arm/boot/dts/bcm270x.dtsi ++++ b/arch/arm/boot/dts/bcm270x.dtsi +@@ -79,6 +79,19 @@ + status = "disabled"; + }; + ++ /* A clone of mmc but with non-removable set */ ++ mmcnr: mmcnr@7e300000 { ++ compatible = "brcm,bcm2835-mmc", "brcm,bcm2835-sdhci"; ++ reg = <0x7e300000 0x100>; ++ interrupts = <2 30>; ++ clocks = <&clocks BCM2835_CLOCK_EMMC>; ++ dmas = <&dma 11>; ++ dma-names = "rx-tx"; ++ brcm,overclock-50 = <0>; ++ non-removable; ++ status = "disabled"; ++ }; ++ + hvs: hvs@7e400000 { + /* Add alias */ + status = "disabled"; +--- a/arch/arm/boot/dts/bcm2710-rpi-3-b-plus.dts ++++ b/arch/arm/boot/dts/bcm2710-rpi-3-b-plus.dts +@@ -15,6 +15,7 @@ + aliases { + serial0 = &uart1; + serial1 = &uart0; ++ mmc1 = &mmcnr; + }; + }; + +@@ -74,13 +75,11 @@ + }; + }; + +-&mmc { ++&mmcnr { + pinctrl-names = "default"; + pinctrl-0 = <&sdio_pins>; +- non-removable; + bus-width = <4>; + status = "okay"; +- brcm,overclock-50 = <0>; + }; + + &firmware { +--- a/arch/arm/boot/dts/bcm2710-rpi-3-b.dts ++++ b/arch/arm/boot/dts/bcm2710-rpi-3-b.dts +@@ -15,6 +15,7 @@ + aliases { + serial0 = &uart1; + serial1 = &uart0; ++ mmc1 = &mmcnr; + }; + }; + +@@ -74,13 +75,11 @@ + }; + }; + +-&mmc { ++&mmcnr { + pinctrl-names = "default"; + pinctrl-0 = <&sdio_pins>; +- non-removable; + bus-width = <4>; + status = "okay"; +- brcm,overclock-50 = <0>; + }; + + &soc { +--- a/arch/arm/boot/dts/overlays/mmc-overlay.dts ++++ b/arch/arm/boot/dts/overlays/mmc-overlay.dts +@@ -33,6 +33,13 @@ + }; + }; + ++ fragment@3 { ++ target = <&mmcnr>; ++ __overlay__ { ++ status = "disabled"; ++ }; ++ }; ++ + __overrides__ { + overclock_50 = <&frag0>,"brcm,overclock-50:0"; + }; +--- a/arch/arm/boot/dts/overlays/sdio-overlay.dts ++++ b/arch/arm/boot/dts/overlays/sdio-overlay.dts +@@ -1,39 +1,26 @@ + /dts-v1/; + /plugin/; + +-/* Enable SDIO from MMC interface via GPIOs 22-27.
