2008-12-15[ARM] S3C64XX: Fix missing definition of s3c64xx_init_io()Ben Dooks
The function s3c64xx_init_io was missing from <plat/cpu.h> and was masked by the SMDK6410 having an local definition. Fix by removing the SMDK6410 variant and adding it to the relevant <plat/cpu.h> file. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C6XX: Add enable for clk_48Ben Dooks

2008-12-15[ARM] S3C6400: Register clk_fout_epllBen Dooks
The clk_fout_epll clock wasn't registered as part of the initial clock work, which can cause problems if it is used by one of the hardware blocks. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C64XX: Add external interrupt group definitionsBen Dooks
Add definitions for the external interrupt groups which accompany the original IRQ_EINT from the s3c24xx series. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-12-15[ARM] S3C64XX: Reduce some output from INFO to DEBUGBen Dooks
Some of the startup output can be reduced to KERN_DEBUG from KERN_INFO as it is only really useful when trying to debug kernel initialisation problems. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-12-15[ARM] S3C64XX: Add IRQ_EINT supportBen Dooks
Add the necessary code to support IRQ_EINT(x) on the S3C64XX series of CPUs. Note, since there is no GPIO configuration support in the kernel, the irq set_type method does not configure the relevant pin to interrupt. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C64XX: Map GPIO blockBen Dooks
Add mapping for GPIO block in the static mappings. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] VIC: Update asm/hardware/vic.h with PL192 informationBen Dooks
The original arch/arm/include/asm/hardware/vic.h was written for the PL190 ARM VIC implementation, and as such does not have any information about the PL192 version. Add details about the PL192 and PL190 specific registers and any changes between the two units. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-12-15[ARM] S3C: Fix PWM build on S3C6400Ben Dooks
The pwm-clock.c needs <mach/map.h> which is included via other means on S3C24XX systems, so ensure it is explicitly included. Remove the includes of regs-clock.h and regs-gpio.h as these are not needed by the build. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C6400: Add <mach/tick.h>Ben Dooks
Add the necessary support for the timer on the S3C6400 and S3C6410 by adding <mach/tick.h> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2008-12-15[ARM] S3C64XX: Initial arch header filesBen Dooks
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>
2008-12-15[ARM] S3C64XX: Initial arch directoryBen Dooks
Add the initial PLAT_S3C64XX support files and directory structure. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C24XX: Split timer pending code outBen Dooks
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>
2008-12-15[ARM] S3C24A0: Initial architecture support filesBen Dooks
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>
2008-12-15[ARM] S3C24XX: Split map.h into plat-s3c24xx and mach-s3c2410Ben Dooks
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>
2008-12-15[ARM] S3C24A0: Serial port definitions and driver support.Sandeep Patil
Add serial support for S3C24A0, based on current S3C2410 UART driver. It adds necessary new defines in regs-serial.h for S3C24A0 and the code to support this device in drivers/serial/s3c24a0.c Signed-off-by: Sandeep Patil <sandeep.patil@azingo.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C24A0: Debug macro definitionsBen Dooks
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>
2008-12-15[ARM] S3C24A0: Correct S3C2410_PA_GPIO in S3C24XX_VA_GPIOSandeep Patil
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>
2008-12-15[ARM] S3C24A0: arch/arm/mach-s3c24a0/include/mach header filesSandeep Patil

2008-12-15[ARM] S3C: Fix scaler1 clock rate informationBen Dooks
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>
2008-12-15[ARM] S3C: Add set_rate/round_rate methods for pwm-scaler clockBen Dooks
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>
2008-12-15[ARM] S3C24XX: Reduce code lineage of gpiolib.cBen Dooks
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>
2008-12-15[ARM] S3C: BUG_ON() if clock has already been registeredBen Dooks
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>
2008-12-15[ARM] S3C: Move pwm-clock.c to arch/arm/plat-s3cBen Dooks

2008-12-15[ARM] S3C: Move core clock support to plat-s3cBen Dooks
Move the core clock registration and definitions in arch/arm/plat-s3c24xx/clock.c to arch/arm/plat-s3c to be shared with the S3C64XX implementations. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C: Move time.c to arch/arm/plat-s3cBen Dooks
Move time.c to arch/arm/plat-s3c to be shared with the S3C64XX implementations. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2008-12-15[ARM] S3C: Move S3C2410_EXTINT to common regs-irqtype.h headerBen Dooks
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>
2008-12-15[ARM] S3C24XX: Move headers from plat-s3c24xx to plat-s3cBen Dooks
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>
2008-12-15[ARM] S3C24XX: Update clock data on resumeBen Dooks
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>
2008-12-15[ARM] S3C24XX: Change clock locking to use spinlocks.Ben Dooks
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>
