* [ARM] S3C64XX: Initial arch header filesBen Dooks2008-12-15
| | | | | | | | | | Add the initial header files for the S3C64XX support to satisfy the minimal requirements to build a kernel. Some definitions will therefore be placeholders or empty functions that will ensure that the system can build and have base functionality. These will be filled in at a later date. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

* [ARM] S3C24XX: Split timer pending code outBen Dooks2008-12-15
| | | | | | | | | Split the timer pending code out to a seperate per-machine header so that when compiling for mach-s3c2410 or mach-s3c24a0 we can use the right timer code without having to #ifdef the timer driver. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24A0: Initial architecture support filesBen Dooks2008-12-15
| | | | | | | | | | Initial architecture support for the S3C24A0 ARCH_S3C24A0. We don't yet add an kconfig entry in the main arch/arm/Kconfig file as the series is not complete, so that is left until enough support is in to be useful. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Split map.h into plat-s3c24xx and mach-s3c2410Ben Dooks2008-12-15
| | | | | | | | | | | | Split the map.h definitions into common S3C24XX code by adding arch/arm/plat-s3c24xx/include/plat/map.h and altering the machine specific header for the S3C24A0. As we add a new <plat/map.h> we move the original one in arch/arm/plat-s3c include directory to be called map-base.h to distinguish the two files. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

* [ARM] S3C24A0: Debug macro definitionsBen Dooks2008-12-15
| | | | | | | | Add the necessary debug macros for the S3C24A0 to enable kernel debugging, and fix a bug with selecting the wrong default debug implementation from the base include. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24A0: Correct S3C2410_PA_GPIO in S3C24XX_VA_GPIOSandeep Patil2008-12-15
| | | | | | | | The definition of S3C24XX_VA_GPIO used S3C2410_PA_GPIO where it should have read S3C24XX_PA_GPIO. Signed-off-by: Sandeep Patil <sandeep.patil@azingo.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24A0: arch/arm/mach-s3c24a0/include/mach header filesSandeep Patil2008-12-15
| | | | | | | | Add initial arch/arm/mach-s3c24a0/include/mach header files for supporting Samsung S3C24A0 SoC. Signed-off-by: Sandeep Patil <sandeep.patil@azingo.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C: Fix scaler1 clock rate informationBen Dooks2008-12-15
| | | | | | | | | | | | | The pwm-scaler0 and pwm-scaler1 clocks have their .id field set to -1 as they are not referenced to any specific device. However, parts of the pwm-clock code used the .id field to identify which scaler clock was being used. Fix the problem by comparing against the pointer to the clock to identify the scalers. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C: Add set_rate/round_rate methods for pwm-scaler clockBen Dooks2008-12-15
| | | | | | | Add the set_rate and round_rate methods for the pwm-scaler clock for use with the time code. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Reduce code lineage of gpiolib.cBen Dooks2008-12-15
| | | | | | | | | | | | | All the s3c24xx gpiolib chips share the same get/set calls and all but one bank shares the same calls for .direction_input and .direction_output methods. Change the initialisation process to use an new call to register the chips that fills in any blank calls with the default values to avoid having to fill them in the structure initialisers. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C: BUG_ON() if clock has already been registeredBen Dooks2008-12-15
| | | | | | | | | | | Add a simple check when registering a clock on whether the clock has already been added to the list. Any attempt to re-register a clock will cause the clock list to be come looped and thus produces silent failures when looking up clocks. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C: Move pwm-clock.c to arch/arm/plat-s3cBen Dooks2008-12-15

* [ARM] S3C: Move time.c to arch/arm/plat-s3cBen Dooks2008-12-15
| | | | | | | Move time.c to arch/arm/plat-s3c to be shared with the S3C64XX implementations. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C: Move S3C2410_EXTINT to common regs-irqtype.h headerBen Dooks2008-12-15
| | | | | | | Add a common include file (regs-irqtype.h) for the IRQ trigger control register values S3C2410_EXTINT*. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Move headers from plat-s3c24xx to plat-s3cBen Dooks2008-12-15
| | | | | | | Move clock.h, cpu.h and devs.h to plat-s3c for use with the s3c64xx support. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Update clock data on resumeBen Dooks2008-12-15
| | | | | | | | | Update the clock settings on resume for suspend/resume support so that if the boot loader changes anything or the system's PLL is reset then we return with the correct settings. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Change clock locking to use spinlocks.Ben Dooks2008-12-15
| | | | | | | | We cannot sleep if we have cpufreq pm enabled during some of the clock operations, so change to use a spinlock to protect the clock system. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] CPUFREQ: S3C24XX serial CPU frequency scaling support.Ben Dooks2008-12-15
| | | | | | | Add support for CPU frequency scalling to the S3C24XX serial driver. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Split pll code out of regs-clock.hBen Dooks2008-12-15
| | | | | | | | | | | | Move the PLL calculation code into it's own header file for re-use with the other plat-s3c24xx based systems such as the S3C24A0. Note, we change the name of s3c2410_get_pll to the more generically named s3c24xx_get_pll as well as the related defintions. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Split DCLK/CLKOUT definitions out of clock.cBen Dooks2008-12-15
| | | | | | | | | Only certain boards need these clocks, and they are not available on some CPUs (such as the S3C24A0) so remove them from arch/arm/plat-s3c24xx/clock.c and into their own file with appropriate Kconfig entries. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Move initialisation code to arch/arm/plat-s3cBen Dooks2008-12-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to add plat-s3c to the build to get the headers that will go in here once moved from include/asm-arm so we may as well put some useful common s3c code in here to stop the errors generated form having nothing built. The cpu setup is now passed the cpu idcode and the table of supported cpus to s3c_init_cpu() to abstract the cpu identification out of the initial io setup. As well as moving the cpu initialisation code, we move the map of the board specific items up to the calling code as none of the map_io() functions actually do anything other than pass this to iotable_init(). This patch does not rename any of the init functions that will be common to s3c24xx and any other s3c architectures as this can be done at a later date as it will touch all the board support files which use functions such as s3c24xx_init_clocks() and s3c24xx_init_uarts(). Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h still has functions that are used by both the cpu and board initialisation functions. This means that each board has definitions specific to the cpu support included and the vice-versa. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Add default <mach/io.h> headerBen Dooks2008-12-15
| | | | | | | | Add a default header for <mach/io.h> for systems such as the S3C24A0 which do not need any of the complex code that the S3C2410 uses. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C24XX: Move vmalloc.h to plat-s3cBen Dooks2008-12-15
| | | | | | | | vmalloc.h is common across all the current s3c platforms, so move it to arch/arm/plat-s3c/include/mach to be used for all the targets. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C: Make <mach/timex.h> commonBen Dooks2008-12-15
| | | | | | | Move <mach/timex.h> to arch/arm/plat-s3c/include/mach/timex.h so it can be the default for all S3C based architectures. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C2410: Move base clock code to plat-s3c24xxBen Dooks2008-12-15
| | | | | | | | Move the S3C2410 base clock list to arch/arm/plat-s3c24xx as this code is common to the S3C2410, S3C2440 and S3C2442 cpus. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] S3C: Add <plat/cpu-freq.h> for initial cpufreq definitionsBen Dooks2008-12-15
