This node is added outside cpu0 as this driver is now a platform driver and a new device structure is needed. Signed-off-by: Amit Daniel Kachhap --- Changes in V3: * Moved the DT node outside cpu0 node as the driver is now a platform driver. arch/arm/boot/dts/exynos5440.dtsi | 12 ++++++++++++ arch/arm/mach-exynos/mach-exynos5-dt.c | 2 ++ 2 files changed, 14 insertions(+), 0 deletions(-) diff --git a/arch/arm/boot/dts/exynos5440.dtsi b/arch/arm/boot/dts/exynos5440.dtsi index 5f3562a..4b29a5a 100644 --- a/arch/arm/boot/dts/exynos5440.dtsi +++ b/arch/arm/boot/dts/exynos5440.dtsi @@ -63,6 +63,18 @@ }; + cpufreq@160000 { + compatible = "samsung,exynos5440-cpufreq"; + reg = <0x160000 0x1000>; + interrupts = <0 57 0>; + operating-points = < + /* KHZ uV */ + 1200000 1025000 + 1000000 975000 + 800000 925000 + >; + }; + serial@B0000 { compatible = "samsung,exynos4210-uart"; reg = <0xB0000 0x1000>; diff --git a/arch/arm/mach-exynos/mach-exynos5-dt.c b/arch/arm/mach-exynos/mach-exynos5-dt.c index acaeb14..0a446c4 100644 --- a/arch/arm/mach-exynos/mach-exynos5-dt.c +++ b/arch/arm/mach-exynos/mach-exynos5-dt.c @@ -145,6 +145,8 @@ static const struct of_dev_auxdata exynos5250_auxdata_lookup[] __initconst = { static const struct of_dev_auxdata exynos5440_auxdata_lookup[] __initconst = { OF_DEV_AUXDATA("samsung,exynos4210-uart", EXYNOS5440_PA_UART0, "exynos4210-uart.0", NULL), + OF_DEV_AUXDATA("samsung,exynos5440-cpufreq", 0x160000, + "exynos5440-cpufreq", NULL), {}, };
