2014-03-21ARM: SAMSUNG: Move Samsung PM debug code into separate fileTomasz Figa
Not all Samsung SoC platforms are going to use the legacy Samsung PM code enabled by CONFIG_SAMSUNG_PM_DEBUG. To allow using Samsung PM debug helpers on such platforms, related code is moved to separate file and a plat/pm-common.h header is added to separate legacy and generic code.

2014-03-21ARM: SAMSUNG: Consolidate PM debug functionsTomasz Figa
This patch removes one-line functions that was used just to pass constant arguments to lower level functions. After previous patches the need for those constants has been eliminated, so the main functions can be called directly.

2014-03-21ARM: SAMSUNG: Use debug_ll_addr() to get UART base addressTomasz Figa
This patch modifies Samsung PM debug helpers to use a multiplatform friendly way of getting base address of debug UART port, so instead of using a per-mach static macro, a generic debug_ll_addr() helper is used.

2014-03-21ARM: SAMSUNG: Save UART DIVSLOT register based on SoC typeTomasz Figa
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.

2014-03-21ARM: SAMSUNG: Add soc_is_s3c2410() helperTomasz Figa
Due to the S3C2410 SoC being quite different from other S3C24xx SoCs in some aspects, such as availability of DIVSLOT register in its UART blocks, there is a need sometimes to check whether we are running on this SoC, not just the S3C24xx series. This patch adds soc_is_s3c2410() helper function for this purpose.

2014-03-21ARM: EXYNOS: Do not resume l2x0 if not enabled before suspendTomasz Figa
Trying to resume l2x0 if it was not enabled before suspend leads to system crash.

2013-12-20ARM: s3c64xx: get rid of custom <mach/gpio.h>Linus Walleij
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 Walleij
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. The biggest hack here is passing const char * pointers through DMA resource, casted to unsigned long, but this is how Samsung DMA wrappers (used to support both s3c-dma and DMA engine in drivers) are designed.

2013-08-29ASoC: Samsung: Do not queue cyclic buffers multiple timesTomasz Figa
The legacy S3C-DMA API required every period of a cyclic buffer to be queued separately. After conversion of Samsung ASoC to Samsung DMA wrappers somebody made an assumption that the same is needed for DMA engine API, which is not true. In effect, Samsung ASoC DMA code was queuing the whole cyclic buffer multiple times with a shift of one period per iteration, leading to: a) severe memory waste - up to 13x times more DMA transfer descriptors are allocated than needed, b) possible memory corruption, because further cyclic buffers were out of the original buffers, due to the offset. This patch fixes this problem by making the legacy S3C-DMA API use the same semantics as DMA engine (the whole cyclic buffer is enqueued at once) and modifying users of Samsung DMA wrappers in cyclic mode to behave appropriately.
