This patch splits up exynos-pmu.c file, and moves PMU configuration data and functions handing those data into SoC specific PMU files, keeping driver structure and common functionality into exynos-pmu.c.
At the same time it also separates compilation of these different SoC PMU files based on CONFIG_ARM64 and CONFIG_ARM. This way we can reduce overhead of ARM64 SoC's PMU getting compiled when kernel is built for ARM and vice-versa. This patch also removes .owner field from exynos-pmu.c as it's redundant for drivers calling platform_driver_register to register platform_driver. Signed-off-by: Pankaj Dubey <pankaj.du...@samsung.com> --- This patch is prepared on top of kgene/for-next and following patch [1] from Amit Daniel. [1]: http://www.spinics.net/lists/linux-samsung-soc/msg39797.html This patch tries to address some of concerns raised for using exynos-pmu.c for ARM and ARM64 based SoC at these threads [2], [3]. [2]: http://www.spinics.net/lists/linux-samsung-soc/msg39809.html [3]: https://lkml.org/lkml/2014/11/24/322 Since Exynos SoC's has similar PMU IP, and already existing bindings can be used, it makes sense to keep single driver for both ARM and ARM64 based SoCs. All common functionalties are in exynos-pmu.c whereas SoC specific data and handling are moved into SoC specific exynosNNNN-pmu files. All changes are compiled tested only. Any improvements/suggestions are most welcome. drivers/soc/samsung/Makefile | 9 +- drivers/soc/samsung/exynos-pmu.c | 1293 +--------------------------------- drivers/soc/samsung/exynos-pmu.h | 63 ++ drivers/soc/samsung/exynos3250-pmu.c | 176 +++++ drivers/soc/samsung/exynos4-pmu.c | 223 ++++++ drivers/soc/samsung/exynos5250-pmu.c | 196 ++++++ drivers/soc/samsung/exynos5420-pmu.c | 298 ++++++++ drivers/soc/samsung/exynos7-pmu.c | 441 ++++++++++++ 8 files changed, 1412 insertions(+), 1287 deletions(-) create mode 100644 drivers/soc/samsung/exynos-pmu.h create mode 100644 drivers/soc/samsung/exynos3250-pmu.c create mode 100644 drivers/soc/samsung/exynos4-pmu.c create mode 100644 drivers/soc/samsung/exynos5250-pmu.c create mode 100644 drivers/soc/samsung/exynos5420-pmu.c create mode 100644 drivers/soc/samsung/exynos7-pmu.c diff --git a/drivers/soc/samsung/Makefile b/drivers/soc/samsung/Makefile index 5a879c6..4a59c39 100644 --- a/drivers/soc/samsung/Makefile +++ b/drivers/soc/samsung/Makefile @@ -1 +1,8 @@ -obj-$(CONFIG_EXYNOS_PMU) += exynos-pmu.o +ifdef CONFIG_ARM +obj-$(CONFIG_EXYNOS_PMU) += exynos-pmu.o exynos3250-pmu.o exynos4-pmu.o \ + exynos5250-pmu.o exynos5420-pmu.o +endif + +ifdef CONFIG_ARM64 +obj-$(CONFIG_EXYNOS_PMU) += exynos-pmu.o exynos7-pmu.o +endif diff --git a/drivers/soc/samsung/exynos-pmu.c b/drivers/soc/samsung/exynos-pmu.c index 3d8b82c..985fefd 100644 --- a/drivers/soc/samsung/exynos-pmu.c +++ b/drivers/soc/samsung/exynos-pmu.c @@ -9,970 +9,22 @@ * published by the Free Software Foundation. */ -#include <linux/io.h> #include <linux/of.h> #include <linux/of_address.h> #include <linux/platform_device.h> -#include <linux/delay.h> #include <linux/notifier.h> #include <linux/reboot.h> #include <linux/soc/samsung/exynos-regs-pmu.h> #include <linux/soc/samsung/exynos-pmu.h> -#define PMU_TABLE_END (-1U) -
