We don't need to bitbang these pins anymore, instead we muxed these pins as SPI, after this change, done in commit 6c69f726, we introduced the following error: pinctrl-single 44e10800.pinmux: pin PIN85 already requested \ by 44e10800.pinmux; cannot claim for 48030000.spi pinctrl-single 44e10800.pinmux: pin-85 (48030000.spi) status -22 Fixes: 6c69f726 ("ARM: dts: am335x-sl50: Enable SPI0 interface and Flash Memory") Cc: <stable@xxxxxxxxxxxxxxx> # 4.11 Signed-off-by: Enric Balletbo i Serra <enric.balletbo@xxxxxxxxxxxxx> --- Changelog since v1: - Cc stable and add kernel version to be applied arch/arm/boot/dts/am335x-sl50.dts | 4 ---- 1 file changed, 4 deletions(-) diff --git a/arch/arm/boot/dts/am335x-sl50.dts b/arch/arm/boot/dts/am335x-sl50.dts index da4f8e3..fc864a8 100644 --- a/arch/arm/boot/dts/am335x-sl50.dts +++ b/arch/arm/boot/dts/am335x-sl50.dts @@ -280,10 +280,6 @@ AM33XX_IOPAD(0x834, PIN_INPUT_PULLUP | MUX_MODE7) /* nKbdReset - gpmc_ad13.gpio1_13 */ AM33XX_IOPAD(0x838, PIN_INPUT_PULLUP | MUX_MODE7) /* nDispReset - gpmc_ad14.gpio1_14 */ AM33XX_IOPAD(0x844, PIN_INPUT_PULLUP | MUX_MODE7) /* USB1_enPower - gpmc_a1.gpio1_17 */ - /* AVR Programming - SPI Bus (bit bang) - Screen and Keyboard */ - AM33XX_IOPAD(0x954, PIN_INPUT_PULLUP | MUX_MODE7) /* Kbd/Disp/BattMOSI spi0_d0.gpio0_3 */ - AM33XX_IOPAD(0x958, PIN_INPUT_PULLUP | MUX_MODE7) /* Kbd/Disp/BattMISO spi0_d1.gpio0_4 */ - AM33XX_IOPAD(0x950, PIN_INPUT_PULLUP | MUX_MODE7) /* Kbd/Disp/BattSCLK spi0_clk.gpio0_2 */ /* PDI Bus - Battery system */ AM33XX_IOPAD(0x840, PIN_INPUT_PULLUP | MUX_MODE7) /* nBattReset gpmc_a0.gpio1_16 */ AM33XX_IOPAD(0x83c, PIN_INPUT_PULLUP | MUX_MODE7) /* BattPDIData gpmc_ad15.gpio1_15 */ -- 2.9.3
