2014-04-08Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAPUwe Kleine-König1-2/+2
If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/cleanup3 Merge "Samsung PM related 2nd updates for v3.15" from Kukjin Kim: From Tomasz Figa <t.figa@samsung.com>: Current Samsung PM code is heavily unprepared for multiplatform systems. The design implies accessing functions and global variables defined in particular mach- subdirectory from common code in plat-, which is not allowed when building ARCH_MULTIPLATFORM. In addition there is a lot of forced code unification, which makes common function handle any possible quirks of all supported SoCs. In the end this design turned out to not work too well, ending with a lot of empty functions exported from mach-, just because code in common pm.c calls them. Moreover, recent trend of moving lower level suspend/resume code to proper drivers, like pinctrl or clk, made a lot of code there redundant, especially on DT-only platforms like Exynos. Note that this branch is based on previous tags/samsung-pm-1 and merge tags/samsung-cleanup-2 because of fix build error from recent changes of <linux/serial_s3c.h> * tag 'samsung-pm-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: ARM: EXYNOS: Fix compilation error in cpuidle.c ARM: S5P64X0: Explicitly include linux/serial_s3c.h in mach/pm-core.h ARM: S3C64XX: Fix build for implicit serial_s3c.h inclusion serial: s3c: Fix build of header without serial_core.h preinclusion ARM: EXYNOS: Allow wake-up using GIC interrupts ARM: EXYNOS: Stop using legacy Samsung PM code ARM: EXYNOS: Remove PM initcalls and useless indirection ARM: EXYNOS: Fix abuse of CONFIG_PM ARM: SAMSUNG: Move s3c_pm_check_* prototypes to plat/pm-common.h ARM: SAMSUNG: Move common save/restore helpers to separate file ARM: SAMSUNG: Move Samsung PM debug code into separate file ARM: SAMSUNG: Consolidate PM debug functions ARM: SAMSUNG: Use debug_ll_addr() to get UART base address ARM: SAMSUNG: Save UART DIVSLOT register based on SoC type ARM: SAMSUNG: Add soc_is_s3c2410() helper ARM: EXYNOS: Do not resume l2x0 if not enabled before suspend Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2014-03-21ARM: samsung: select CRC32 for SAMSUNG_PM_CHECKArnd Bergmann1-1/+2
The Samsung pm_check code uses the crc32 library code, which can be built as a loadable module, in which case we get a link error building the kernel. A better solution is to use 'select CRC32', which is what all other users of this code do, as it ensures it is always built-in.

The only SoC that does not have DIVSLOT register is S3C2410, so instead of exporting a variable for platforms to set if DIVSLOT register should be preserved, it's enough to simply check whether we are running on a S3C2410 instead.

2013-12-20ARM: s3c64xx: get rid of custom <mach/gpio.h>Linus Walleij1-0/+3
This isolates the custom S3C64xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x64xx.h> as this is used in a few different places in the kernel, removing the need to depend on the implicit inclusion of <mach/gpio.h> from <linux/gpio.h> and thus getting rid of a few nasty cross-dependencies. Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead roof the number of GPIOs for this platform: First sum up all the GPIO banks from A to Q: 187 GPIOs. Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA, 128, so in total maximum 187+16+128 = 331 GPIOs, so let's take the same roof as for S3C24XX: 512. This way we can do away with the GPIO calculation macros for GPIO_BOARD_START, BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.

2013-12-20ARM: s3c24xx: get rid of custom <mach/gpio.h>Linus Walleij2-0/+4
This isolates the custom S3C24xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x24xx.h> as this is used in a few different places in the kernel, removing the need to depend on the implicit inclusion of <mach/gpio.h> from <linux/gpio.h> and thus getting rid of a few nasty cross-dependencies. We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff. The biggest this can ever be for the S3C24XX is CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512 is the absolute roof value on this platform. So we set the size of ARCH_NR_GPIO to this and the GPIOs array will fit any S3C24XX platform, as per pattern from other archs. ChangeLog v2->v3: - Move the movement of the S3C64XX gpio.h file out of this patch and into the follow-up patch where it belongs. ChangeLog v1->v2: - Added an #ifdef ARCH_S3C24XX around the header inclusion in drivers/gpio/gpio-samsung.c as we would otherwise have colliding definitions when compiling S3C64XX. - Rename inclusion guard in the header file.

This patch adds all required platform-specific data and initialization code to support the generic amba-pl08x driver on S3C64xx SoCs. Also some compatibility definitions are added to make the transition from legacy API to DMA engine easier.
