But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table. Signed-off-by: Javier Martinez Canillas --- Changes in v5: - Only replace atmel variant but keep other EEPROM vendors (Geert Uytterhoeven). Changes in v4: - Only use the atmel manufacturer in the compatible string instead of keeping the deprecated ones (Rob Herring). Changes in v3: None Changes in v2: None arch/powerpc/boot/dts/mpc8308_p1m.dts | 2 +- arch/powerpc/boot/dts/mpc8349emitx.dts | 4 ++-- arch/powerpc/boot/dts/mpc8377_rdb.dts | 2 +- arch/powerpc/boot/dts/mpc8377_wlan.dts | 2 +- arch/powerpc/boot/dts/mpc8378_rdb.dts | 2 +- arch/powerpc/boot/dts/mpc8379_rdb.dts | 2 +- 6 files changed, 7 insertions(+), 7 deletions(-) diff --git a/arch/powerpc/boot/dts/mpc8308_p1m.dts b/arch/powerpc/boot/dts/mpc8308_p1m.dts index 57f86cdf9f36..cab933b3957a 100644 --- a/arch/powerpc/boot/dts/mpc8308_p1m.dts +++ b/arch/powerpc/boot/dts/mpc8308_p1m.dts @@ -123,7 +123,7 @@ interrupt-parent = <&ipic>; dfsrr; fram@50 { - compatible = "ramtron,24c64"; + compatible = "ramtron,24c64", "atmel,24c64"; reg = <0x50>; }; }; diff --git a/arch/powerpc/boot/dts/mpc8349emitx.dts b/arch/powerpc/boot/dts/mpc8349emitx.dts index 90aed3ac2f69..648a85858eb5 100644 --- a/arch/powerpc/boot/dts/mpc8349emitx.dts +++ b/arch/powerpc/boot/dts/mpc8349emitx.dts @@ -92,7 +92,7 @@ dfsrr; eeprom: at24@50 { - compatible = "st,24c256"; + compatible = "st,24c256", "atmel,24c256"; reg = <0x50>; }; @@ -130,7 +130,7 @@ }; spd: at24@51 { - compatible = "at24,spd"; + compatible = "atmel,spd"; reg = <0x51>; }; diff --git a/arch/powerpc/boot/dts/mpc8377_rdb.dts b/arch/powerpc/boot/dts/mpc8377_rdb.dts index e32613963ab0..5e85d8c93bca 100644 --- a/arch/powerpc/boot/dts/mpc8377_rdb.dts +++ b/arch/powerpc/boot/dts/mpc8377_rdb.dts @@ -150,7 +150,7 @@ }; at24@50 { - compatible = "at24,24c256"; + compatible = "atmel,24c256"; reg = <0x50>; }; diff --git a/arch/powerpc/boot/dts/mpc8377_wlan.dts b/arch/powerpc/boot/dts/mpc8377_wlan.dts index c0c790168b96..fee15fcbb46f 100644 --- a/arch/powerpc/boot/dts/mpc8377_wlan.dts +++ b/arch/powerpc/boot/dts/mpc8377_wlan.dts @@ -135,7 +135,7 @@ dfsrr; at24@50 { - compatible = "at24,24c256"; + compatible = "atmel,24c256"; reg = <0x50>; }; diff --git a/arch/powerpc/boot/dts/mpc8378_rdb.dts b/arch/powerpc/boot/dts/mpc8378_rdb.dts index 71842fcd621f..e973d61956b9 100644 --- a/arch/powerpc/boot/dts/mpc8378_rdb.dts +++ b/arch/powerpc/boot/dts/mpc8378_rdb.dts @@ -150,7 +150,7 @@ }; at24@50 { - compatible = "at24,24c256"; + compatible = "atmel,24c256"; reg = <0x50>; }; diff --git a/arch/powerpc/boot/dts/mpc8379_rdb.dts b/arch/powerpc/boot/dts/mpc8379_rdb.dts index e442a29b2fe0..ed5d12ff2ee0 100644 --- a/arch/powerpc/boot/dts/mpc8379_rdb.dts +++ b/arch/powerpc/boot/dts/mpc8379_rdb.dts @@ -148,7 +148,7 @@ }; at24@50 { - compatible = "at24,24c256"; + compatible = "atmel,24c256"; reg = <0x50>; }; -- 2.9.3
