| * [ARM] S3C: Add GPIO chip trackingBen Dooks2008-12-15
| | | | | | | | | | | | | | | | | | The gpiolib driver keeps its chip array to itself and having a separate array for s3c-only gpios stops any non-s3c gpio being used in one of the s3c specific configuration calls. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| * [ARM] S3C: Move common GPIO code from plat-s3c24xxBen Dooks2008-12-15
| | | | | | | | | | | | | | Move the common parts of the GPIO code into plat-s3c for use with both the s3c24xx and s3c64xx systems. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| * | [ARM] S3C: Update time initialisation to fix S3C64XX time problemsBen Dooks2008-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The S3C64XX timer is running at the wrong rate due to the assumptions made in the timer initialisation about the way the pwm dividers work. This means that time on the S3C64XX runs twice as fast as it should. Fix the problem by moving to using the clk framework to setup the pwm timer clock muxes, as the pwm-clock code has all the necessary knowledge of how the timer clock inputs are routed. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| * | [ARM] S3C64XX: Update TCFG for new timer divider settings.Ben Dooks2008-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The S3C64XX series has a new TCFG divider setting to allow the clock directly through, which means that we need to update the pwm-clock code to cope with this. Add <mach/pwm-clock.h> containing the specific code to deal with the TCFG divider settings and provide any other per-arch data that the pwm-clock driver needs to function. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| * | [ARM] S3C64XX: Fix missing definition of s3c64xx_init_io()Ben Dooks2008-12-15
| |/ | | | | | | | | | | | | | | | | | | 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>
| * [ARM] S3C6400: serial support for S3C6400 and S3C6410 SoCsBen Dooks2008-12-15
| | | | | | | | | | | | | | Add support to the Samsung serial driver for the S3C6400 and S3C6410 serial ports. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| * [ARM] S3C64XX: Clock support for S3C6400/S3C6410Ben Dooks2008-12-15
| | | | | | | | | | | | | | | | Add the PLL clock initialisation and clock registration and include the clocks sourced via CLKDIVx for most of the on-chip peripherals. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| * [ARM] S3C: Add TICK_MAX for timer codeBen Dooks2008-12-15
| | | | | | | | | | | | | | | | Add TICK_MAX definition for the timer code as the S3C64XX series have 32bit capable PWM timers. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| * [ARM] S3C64XX: Add initial clock frameworkBen Dooks2008-12-15
| | | | | | | | | | | | | | | | Add the initial clocks definitions for the s3c6400 and s3c6410. Move the epll and ext clock from the s3c2443 support into the common code. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| * [ARM] S3C64XX: Map timer memory and interruptsBen Dooks2008-12-15
| | | | | | | | | | | | | | Add the physical to virtual memory mapping and the necessary interrupt demuxing for the PWM timer blocks. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
| * [ARM] S3C: Fix PWM build on S3C6400Ben Dooks2008-12-15
| | | | | | | | | | | | | | | | | | | | | | 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>
| * [ARM] S3C64XX: Add VIC0 and VIC1 sourced interriptsBen Dooks2008-12-15
| | | | | | | | | | | | | | Add and initialise the two VIC (PL192) found on the S3C64XX series CPUs. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| * [ARM] S3C64XX: Initial arch directoryBen Dooks2008-12-15
| | | | | | | | | | | | | | Add the initial PLAT_S3C64XX support files and directory structure. 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: Serial port definitions and driver support.Sandeep Patil2008-12-15
| | | | | | | | | | | | | | | | | | | | 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>
| * [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] S3C24XX: ADC driver coreBen Dooks2008-12-18
| | | | | | | | | | | | | | | | A common core driver for the S3C24XX ADC block so that the touchscreen, hwmon and any other drivers can share the resource. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* | [ARM] S3C: Add UART FIFO selection during arch decompressionBen Dooks2008-12-16
|/ | | | | | | | | | Add a configuration option to start the UART FIFOs during the decompressions sequence to improve boot time when the bootloader fails to enable the UART FIFOs. For example, the SMDK6410 UBoot 1.1.6 leaves the FIFOs off. 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] 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
