| * [ARM] S3C24XX: ADC driver coreBen Dooks2008-12-185-1/+418
| | | | | | | | | | | | | | | | 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 Dooks2008-12-162-0/+36
| | | | | | | | | | | | | | | | | | | | 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 Dooks2008-12-151-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Dooks2008-12-151-4/+47
| | | | | | | | | | | | | | 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 Dooks2008-12-151-27/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [ARM] S3C: BUG_ON() if clock has already been registeredBen Dooks2008-12-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | 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 core clock support to plat-s3cBen Dooks2008-12-153-314/+357

| * [ARM] S3C24XX: Move headers from plat-s3c24xx to plat-s3cBen Dooks2008-12-153-4/+3
| | | | | | | | | | | | | | 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 Dooks2008-12-157-36/+104
| | | | | | | | | | | | | | | | | | 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 Dooks2008-12-153-18/+23
| | | | | | | | | | | | | | | | 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 Dooks2008-12-152-0/+102

| * [ARM] S3C24XX: Split pll code out of regs-clock.hBen Dooks2008-12-157-41/+49
| | | | | | | | | | | | | | | | | | | | | | | | 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 Dooks2008-12-156-171/+204
| | | | | | | | | | | | | | | | | | 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 Dooks2008-12-1513-155/+201
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Dooks2008-12-151-0/+18
| | | | | | | | | | | | | | | | 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 Dooks2008-12-151-1/+1
| | | | | | | | | | | | | | | | 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 Dooks2008-12-151-0/+0
| | | | | | | | | | | | | | 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 Dooks2008-12-155-6/+9
| | | | | | | | | | | | | | | | 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 Dooks2008-12-151-0/+94

| * [ARM] Kirkwood: properly handle the WAN port on newer RD88F6281 boardsRonen Shitrit2008-12-111-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | On newer versions of the RD88F6281 board, the WAN port is connected to its own ethernet port on the CPU, via a separate PHY, whereas on older versions of the board, it is connected to one of the PHYs in the ethernet switch. In the RD8F6281 setup code, detect which version of the board we are running on, and instantiate the ethernet ports and switch driver accordingly.

| | | | | | | | | | | | | | | | | | | | The 88F5182 found in the DNS-323 rev B1 (and some other devices, such as the CH3SNAS) require different initialisation of the SATA controller and MPP registers. Tested on a DNS-323 rev B1. Signed-off-by: Matt Palmer <mpalmer@hezmatt.org>

It's possible (though unlikely) that an A1 will have the MAC in a different location in flash. Signed-off-by: Matt Palmer <mpalmer@hezmatt.org>
