These add device tree entry for qspi controller driver on dra7-evm. Signed-off-by: Sourav Poddar <sourav.poddar@xxxxxx> --- Done and tested on top of linux-next + benoit for_15 + tony crossbar branch + crossbar dts patches. v2->v3: This was added as part of the following series, http://www.spinics.net/lists/linux-omap/msg101024.html Few patches of the above series are picked. Sending this dts patch with updates[1] to enable spi mode operations with flash device. [1]: - Enables only SPI mode operations - Add partition table - Add crossbar interrupt value. arch/arm/boot/dts/dra7-evm.dts | 80 ++++++++++++++++++++++++++++++++++++++++ arch/arm/boot/dts/dra7.dtsi | 13 +++++++ 2 files changed, 93 insertions(+) diff --git a/arch/arm/boot/dts/dra7-evm.dts b/arch/arm/boot/dts/dra7-evm.dts index 5babba0..986fcf3 100644 --- a/arch/arm/boot/dts/dra7-evm.dts +++ b/arch/arm/boot/dts/dra7-evm.dts @@ -93,6 +93,21 @@ 0x24c (PIN_INPUT_SLEW | MUX_MODE0) /* uart3_txd */ >; }; + + qspi1_pins: pinmux_qspi1_pins { + pinctrl-single,pins = < + 0x4c (PIN_INPUT | MUX_MODE1) /* gpmc_a3.qspi1_cs2 */ + 0x50 (PIN_INPUT | MUX_MODE1) /* gpmc_a4.qspi1_cs3 */ + 0x74 (PIN_INPUT | MUX_MODE1) /* gpmc_a13.qspi1_rtclk */ + 0x78 (PIN_INPUT | MUX_MODE1) /* gpmc_a14.qspi1_d3 */ + 0x7c (PIN_INPUT | MUX_MODE1) /* gpmc_a15.qspi1_d2 */ + 0x80 (PIN_INPUT | MUX_MODE1) /* gpmc_a16.qspi1_d1 */ + 0x84 (PIN_INPUT | MUX_MODE1) /* gpmc_a17.qspi1_d0 */ + 0x88 (PIN_INPUT | MUX_MODE1) /* qpmc_a18.qspi1_sclk */ + 0xb8 (PIN_INPUT_PULLUP | MUX_MODE1) /* gpmc_cs2.qspi1_cs0 */ + 0xbc (PIN_INPUT_PULLUP | MUX_MODE1) /* gpmc_cs3.qspi1_cs1 */ + >; + }; }; &i2c1 { @@ -273,3 +288,68 @@ &cpu0 { cpu0-supply = <&smps123_reg>; }; + +&qspi { + status = "okay"; + pinctrl-names = "default"; + pinctrl-0 = <&qspi1_pins>; + + spi-max-frequency = <48000000>; + m25p80@0 { + compatible = "s25fl256s1"; + spi-max-frequency = <48000000>; + reg = <0>; + spi-tx-bus-width = <1>; + spi-rx-bus-width = <4>; + spi-cpol; + spi-cpha; + #address-cells = <1>; + #size-cells = <1>; + + /* MTD partition table. + * The ROM checks the first four physical blocks + * for a valid file to boot and the flash here is + * 64KiB block size. + */ + partition@0 { + label = "QSPI.SPL"; + reg = <0x00000000 0x000010000>; + }; + partition@1 { + label = "QSPI.SPL.backup1"; + reg = <0x00010000 0x00010000>; + }; + partition@2 { + label = "QSPI.SPL.backup2"; + reg = <0x00020000 0x00010000>; + }; + partition@3 { + label = "QSPI.SPL.backup3"; + reg = <0x00030000 0x00010000>; + }; + partition@4 { + label = "QSPI.u-boot"; + reg = <0x00040000 0x00180000>; + }; + partition@5 { + label = "QSPI.u-boot-spl-os"; + reg = <0x001c0000 0x00010000>; + }; + partition@6 { + label = "QSPI.u-boot-env"; + reg = <0x001d0000 0x00010000>; + }; + partition@7 { + label = "QSPI.u-boot-env.backup1"; + reg = <0x001e0000 0x0010000>; + }; + partition@8 { + label = "QSPI.kernel"; + reg = <0x001f0000 0x00500000>; + }; + partition@9 { + label = "QSPI.file-system"; + reg = <0x006f0000 0x01910000>; + }; + }; +}; diff --git a/arch/arm/boot/dts/dra7.dtsi b/arch/arm/boot/dts/dra7.dtsi index 5d2ff52..a7a2fa8 100644 --- a/arch/arm/boot/dts/dra7.dtsi +++ b/arch/arm/boot/dts/dra7.dtsi @@ -645,6 +645,19 @@ dma-names = "tx0", "rx0"; status = "disabled"; }; + + qspi: qspi@4b300000 { + compatible = "ti,dra7xxx-qspi"; + reg = <0x4b300000 0x100>; + #address-cells = <1>; + #size-cells = <0>; + ti,hwmods = "qspi"; + clocks = <&qspi_gfclk_div>; + clock-names = "fck"; + num-cs = <4>; + interrupts = <0 343 0x4>; + status = "disabled"; + }; }; }; -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
