2020-08-20ARM: s3c: move into a common directoryArnd Bergmann1-94/+0
s3c24xx and s3c64xx have a lot in common, but are split across three separate directories, which makes the interaction of the header files more complicated than necessary. Move all three directories into a new mach-s3c, with a minimal set of changes to each file.

2020-08-20ARM: s3c: remove cpufreq header dependenciesArnd Bergmann1-1/+1
The cpufreq drivers are split between the machine directory and the drivers/cpufreq directory. In order to share header files after we convert s3c to multiplatform, those headers have to live in a different global location. Move them to linux/soc/samsung/ in lack of a better place.

2020-08-19ARM: s3c64xx: remove mach/hardware.hArnd Bergmann1-1/+0
This header is empty and conflicts with the s3c24xx version of the same file when we merge the two, so stop including it.

2015-12-01ARM: s3c64xx: prepare initcalls for multiplatformArnd Bergmann1-1/+1
In a multiplatform kernel, each initcall is run regardless of the platform it is meant for, so it must not attempt to access SoC-specific registers. This adds 'if (soc_is_s3c64xx)' to all initcalls that are specific to the s3c64xx platform, to prevent them from breaking other platforms once we can build them into a combined kernel.

2014-07-18ARM: SAMSUNG: Remove legacy clock codeTomasz Figa1-1/+0
Since S5PV210 now has a complete clock driver using Common Clock Framework, there is no reason to keep the old code. Remove it together with the whole legacy Samsung-specific clock framework which no longer has any users.

2014-02-14ARM: SAMSUNG: Replace inclusion of plat/regs-serial.h header fileTushar Behera1-1/+1
regs-serial.h only includes linux/serial_s3c.h. Include this header directly to remove unnecessary platform dependency.

2013-09-17ARM: S3C64XX: Bypass legacy initialization when booting with DTTomasz Figa1-0/+9
This patch allows bypassing most of legacy initialization when booting an S3C64xx-based board using device tree, by adding conditional checks for DT presence to initcalls which are no longer necessary when booting with DT..

This patch introduces common.[ch] which are used only in the arch/arm/mach-s3c64xx/ directory. The common.c file merges the cpu.c, irq.c and irq-eint.c which are used commonly on S3C64XX SoCs and the common.h file replaces with plat/s3c6400.h and plat/s3c6410.h files.

2010-05-20ARM: SAMSUNG: Add platform support code for OneNAND controllerMarek Szyprowski1-0/+3
This patch adds setup code for Samsung OneNAND controller driver. The driver needs to be aware on which SoC it is running, so the actual device id is being changed in cpu init code. S3C64xx SoCs have 2 OneNAND controllers while S5PC100 and S5PC110 has only one.

Turn the init sequence of s3c24xx_register_baseclocks(xtal); s3c64xx_register_clocks(); s3c6400_register_clocks(S3C6410_CLKDIV0_ARM_MASK); into a single call as this is now contained within one file. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-02-21ARM: S3C64XX: Move core support to mach-s3c64xxBen Dooks1-2/+2
Move the core S3C64XX support to mach-s3c64xx as it is unlikely to be used outside of this directory. Also move the SoC header files in with it. This includes the clock, cpu, cpufreq, dma, gpiolib and pll support. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-02-21ARM: S3C64XX: Move headers into machine include directoryBen Dooks1-1/+1
Move the register and GPIO definition files from plat-s3c64xx into the machine include direcotry as they are unlikely to be reused outside mach-s3c64xx. This move includes removing the empty <mach/regs-clock.h> and replacing it with the <plat/regs-clock.h> implementation. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-26ARM: S3C64XX: Remove useless IO descriptor from S3C6410Ben Dooks1-12/+0
The iotable in arch/arm/mach-s3c64xx/s3c6410.c is currently empty and therefore can be removed from the build. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-01-26ARM: S3C64XX: Merge mach-s3c6400 and mach-s3c6410Ben Dooks1-0/+105
As per discussions with Russell King on linux-arm-kernel, it appears that both mach-s3c6400 and mach-s3c6410 are so close together that they should simply be merged into mach-s3c64xx. Note, this patch does not eliminate any of the bits that are still common, it is simply a move of the two directories together, any further common code will be eliminated or moved in further patches.
