No system currently in use has an FF board, and its connector on the Sentinel Dome is not populated, so these addresses never acknowledge: the pca953x driver fails to probe the eight PCA9537 nodes on every boot and the at24 driver does not bind to the eight EEPROM nodes. Remove the nodes so that the devicetree matches the actual hardware. Signed-off-by: Sean He Signed-off-by: Eric Yang --- The changelog was drafted with an AI assistant (Claude Code) and reviewed by the submitter. --- Changes in v2: - Reworded the commit message: the FF board is a separate board, no system in use has it, and its connector is not populated - Dropped the verification paragraph - Link to v1: https://lore.kernel.org/r/20261105-yv4-remove-ff-nodes-v1-1-aa707a9577b7@gmail.com --- .../dts/aspeed/aspeed-bmc-facebook-yosemite4.dts | 96 ---------------------- 1 file changed, 96 deletions(-) diff --git a/arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-yosemite4.dts b/arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-yosemite4.dts index e4172be84..4c7c96ce4 100644 --- a/arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-yosemite4.dts +++ b/arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-yosemite4.dts @@ -604,18 +604,6 @@ imux16: i2c@0 { reg = <0>; #address-cells = <1>; #size-cells = <0>; - gpio@49 { - compatible = "nxp,pca9537"; - reg = <0x49>; - gpio-controller; - #gpio-cells = <2>; - }; - - eeprom@50 { - compatible = "atmel,24c128"; - reg = <0x50>; - }; - eeprom@51 { compatible = "atmel,24c128"; reg = <0x51>; @@ -631,18 +619,6 @@ imux17: i2c@1 { reg = <1>; #address-cells = <1>; #size-cells = <0>; - gpio@49 { - compatible = "nxp,pca9537"; - reg = <0x49>; - gpio-controller; - #gpio-cells = <2>; - }; - - eeprom@50 { - compatible = "atmel,24c128"; - reg = <0x50>; - }; - eeprom@51 { compatible = "atmel,24c128"; reg = <0x51>; @@ -658,18 +634,6 @@ imux18: i2c@2 { reg = <2>; #address-cells = <1>; #size-cells = <0>; - gpio@49 { - compatible = "nxp,pca9537"; - reg = <0x49>; - gpio-controller; - #gpio-cells = <2>; - }; - - eeprom@50 { - compatible = "atmel,24c128"; - reg = <0x50>; - }; - eeprom@51 { compatible = "atmel,24c128"; reg = <0x51>; @@ -685,18 +649,6 @@ imux19: i2c@3 { reg = <3>; #address-cells = <1>; #size-cells = <0>; - gpio@49 { - compatible = "nxp,pca9537"; - reg = <0x49>; - gpio-controller; - #gpio-cells = <2>; - }; - - eeprom@50 { - compatible = "atmel,24c128"; - reg = <0x50>; - }; - eeprom@51 { compatible = "atmel,24c128"; reg = <0x51>; @@ -726,18 +678,6 @@ imux20: i2c@0 { reg = <0>; #address-cells = <1>; #size-cells = <0>; - gpio@49 { - compatible = "nxp,pca9537"; - reg = <0x49>; - gpio-controller; - #gpio-cells = <2>; - }; - - eeprom@50 { - compatible = "atmel,24c128"; - reg = <0x50>; - }; - eeprom@51 { compatible = "atmel,24c128"; reg = <0x51>; @@ -753,18 +693,6 @@ imux21: i2c@1 { reg = <1>; #address-cells = <1>; #size-cells = <0>; - gpio@49 { - compatible = "nxp,pca9537"; - reg = <0x49>; - gpio-controller; - #gpio-cells = <2>; - }; - - eeprom@50 { - compatible = "atmel,24c128"; - reg = <0x50>; - }; - eeprom@51 { compatible = "atmel,24c128"; reg = <0x51>; @@ -780,18 +708,6 @@ imux22: i2c@2 { reg = <2>; #address-cells = <1>; #size-cells = <0>; - gpio@49 { - compatible = "nxp,pca9537"; - reg = <0x49>; - gpio-controller; - #gpio-cells = <2>; - }; - - eeprom@50 { - compatible = "atmel,24c128"; - reg = <0x50>; - }; - eeprom@51 { compatible = "atmel,24c128"; reg = <0x51>; @@ -807,18 +723,6 @@ imux23: i2c@3 { reg = <3>; #address-cells = <1>; #size-cells = <0>; - gpio@49 { - compatible = "nxp,pca9537"; - reg = <0x49>; - gpio-controller; - #gpio-cells = <2>; - }; - - eeprom@50 { - compatible = "atmel,24c128"; - reg = <0x50>; - }; - eeprom@51 { compatible = "atmel,24c128"; reg = <0x51>; --- base-commit: 6628e7d4c6b25c8d18f1345e3a20d21829aae7e4 change-id: 20261103-yv4-remove-ff-nodes-9e20104d2362 Best regards, -- Eric Yang
