2018-01-03ARM: S3C24XX: Add SPDX license identifiersKrzysztof Kozlowski1-4/+1
Replace GPL license statements with SPDX license identifiers (GPL-2.0 and GPL-2.0+). The h1940-bluetooth.c was licensed under GPL-1.0. This also adds GPL-2.0 to few files lacking license statement. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
2014-09-13ARM: S3C24XX: remove separate restart codeHeiko Stuebner1-5/+0
The restart-handler series from Guenter Roeck got accepted recently and implements among other things also the restart handler in the samsung watchdog driver and where applicable in the clock drivers. So there is no need for having the restart callbacks in s3c24xx boards anymore. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2014-05-13ARM: S3C24XX: remove legacy clock codeHeiko Stuebner1-2/+0
With the move to the common clock framework completed for s3c2410, s3c2440 and s3c2442, the legacy clock code for these machines can go away too. This also includes the legacy dclk code, as all legacy users are converted.

2014-05-13ARM: S3C24XX: add platform code for conversion to the common clock frameworkHeiko Stuebner1-0/+7
This adds the necessary init functions to init the clocks from the common clock framework and necessary CONFIG_SAMSUNG_CLOCK ifdefs around the legacy clock code. This also includes empty stubs for the *_setup_clocks functions that are called from the cpufreq driver on resume.

2014-05-13ARM: S3C24XX: enable usage of common dclk if common clock framework is enabledHeiko Stuebner1-0/+2
Add platform device and select the correct implementation automatically depending on wether the old samsung_clock or the common clock framework is enabled. This is only done for machines already using the old dclk implementation, as everybody else should move to use dt anyway. The machine-specific settings for the external clocks will have to be set by somebody with knowledge about the specific hardware.

2014-04-14ARM: S3C24XX: convert s3c2412 to common clock frameworkHeiko Stuebner1-0/+4

2014-04-14ARM: S3C24XX: Convert s3c2416 and s3c2443 to common clock frameworkHeiko Stuebner1-0/+6
This converts the mentioned platforms to use the newly introduced driver for the common clock framework for them. With this the whole legacy clock structure can go away too.

2013-10-21ARM: S3C24XX: add dma pdata for s3c2410, s3c2440 and s3c2442Heiko Stuebner1-0/+2
s3c2410 and s3c2442 share the same dma channels while s3c2440 has slight differences. But on all three the reachable sources per dma channel has constraints attached and thus encodes the usable combinations using the S3C24XX_DMA_CHANREQ macro. This also fixes the warning about s3c2410_dma_resource being unused as reported by Olof Johansson.

2013-03-07ARM: S3C24XX: move s3c24xx_init_irq to s3c2410_init_irqHeiko Stuebner1-0/+1
The s3c24xx_init_irq function that was the base for all irq inits is now only used to initialize the real s3c2410 irqs. Therefore rename it and also move its declaration from plat/cpu.h to common.h The eint declaration is used by the vast majority of the SoCs and gets therefore placed outside any ifdefs.

s3c2440 and s3c2442 need separate init functions, as the s3c2440 contains even more differing irqs that will be moved in the following patch. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

Only the _init, _init_clocks, _init_uarts and _map_io functions need NULL defines, as they are used in the cpu map. Further integrate the two restart functions already in common.h in their respective soc part and compact the numerous empty lines.
