You should write a comment saying how this enum is used and describing its values. Also the name is too generic. It should be prefixed with exynos5260_ probably. > + > extern unsigned long l2x0_regs_phys; > struct exynos_pmu_conf { > void __iomem *reg; > diff --git a/arch/arm/mach-exynos/include/mach/map.h b/arch/arm/mach-exynos/include/mach/map.h > index bd6fa02..cc190b9 100644 > --- a/arch/arm/mach-exynos/include/mach/map.h > +++ b/arch/arm/mach-exynos/include/mach/map.h > @@ -31,6 +31,23 @@ > #define EXYNOS5250_PA_SYSRAM_NS 0x0204F000 > #define EXYNOS5260_PA_SYSRAM_NS 0x02073000 > > +#define EXYNOS5260_PA_PMU 0x10D50000 > +#define EXYNOS5260_PA_SROMC 0x12180000 > +#define EXYNOS5260_PA_PWM 0x12D90000 > + > +#define EXYNOS5260_PA_SYS_PERI 0x10220000 > +#define EXYNOS5260_PA_SYS_MIF 0x10D00000 > +#define EXYNOS5260_PA_SYS_MFC 0x110A0000 > +#define EXYNOS5260_PA_SYS_KFC 0x10710000 > +#define EXYNOS5260_PA_SYS_ISP 0x133E0000 > +#define EXYNOS5260_PA_SYS_GSCL 0x13F20000 > +#define EXYNOS5260_PA_SYS_G3D 0x11850000 > +#define EXYNOS5260_PA_SYS_G2D 0x10A20000 > +#define EXYNOS5260_PA_SYS_FSYS 0x122F0000 > +#define EXYNOS5260_PA_SYS_EGL 0x10610000 > +#define EXYNOS5260_PA_SYS_DISP 0x14540000 > +#define EXYNOS5260_PA_SYS_AUD 0x128F0000 > + Do you really need all the static addresses above? > #define EXYNOS_PA_CHIPID 0x10000000 > > #define EXYNOS4_PA_SYSCON 0x10010000 > diff --git a/arch/arm/mach-exynos/include/mach/regs-pmu.h b/arch/arm/mach-exynos/include/mach/regs-pmu.h > index 09ae29a..ac53f85 100644 > --- a/arch/arm/mach-exynos/include/mach/regs-pmu.h > +++ b/arch/arm/mach-exynos/include/mach/regs-pmu.h > @@ -125,6 +125,25 @@ > #define S5P_ARM_CORE1_STATUS S5P_PMUREG(0x2084) > #define S5P_ARM_CORE1_OPTION S5P_PMUREG(0x2088) [snip] > +#define EXYNOS5260_CORE_LOCAL_PWR_EN 0xf > +#define EXYNOS5260_CPUS_PER_CLUSTER 4 > +#define EXYNOS5260_USE_DELAYED_RESET_ASSERTION (1 << 12) > + > +#define EXYNOS5260_WAKEUP_STAT2 S5P_PMUREG(0x0604) > +#define EXYNOS5260_WAKEUP_STAT3 S5P_PMUREG(0x0608) > +#define EXYNOS5260_EINT_WAKEUP_MASK S5P_PMUREG(0x060C) > +#define EXYNOS5260_WAKEUP_MASK S5P_PMUREG(0x0610) > +#define EXYNOS5260_WAKEUP_MASK2 S5P_PMUREG(0x0614) > +#define EXYNOS5260_WAKEUP_MASK3 S5P_PMUREG(0x0618) > + > + > +/* Exynos5260 specific PMU SYS_PWR_REGs */ > +#define EXYNOS5260_A15_EGL0_SYS_PWR_REG S5P_PMUREG(0x1000) CodingStyle: There should be just one space between #define and definiton name.

I wonder what it means. It doesn't seem to be the Answer to the Ultimate Question of Life, The Universe, and Everything, though. ;) [1] http://en.wikipedia.org/wiki/Phrases_from_The_Hitchhiker's_Guide_to_the_Galaxy#Answer_to_the_Ultimate_Question_of_Life.2C_the_Universe.2C_and_Everything_.2842.29 > + } > + > + for (i = cpu_s; i < cpu_f; i++) { > + option = __raw_readl(EXYNOS_ARM_CORE_OPTION(i)); > + option = on ? > + (option | EXYNOS5260_USE_DELAYED_RESET_ASSERTION) : > + (option & ~EXYNOS5260_USE_DELAYED_RESET_ASSERTION); Readability of this is quite poor.

What about boards with different polarity of power hold signal in used PMIC? I believe this should be set correctly by the bootloader and never changed later, except in power off callback.
