FF was planned in the early Yosemite 4 design but has not been used since the DVT stage, so these addresses never acknowledge. The pca953x driver fails to probe all eight pca9537 nodes on every boot, and the at24 driver does not bind to the eight EEPROM nodes either. Remove the nodes for both devices. 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. Tested on two Yosemite 4 BMCs, baseline vs patched image: the eight pca9537 nodes and the sixteen 0x49/0x50 slot-bus clients are gone, while the 0x51/0x54 clients, gpio chips and FRU objects are unchanged. CHECK_DTBS=y W=1 shows no new warnings and the DTB diff is exactly the sixteen removed nodes. --- .../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
