2009-05-15[ARM] S3C24XX: Fix unused code warning in arch/arm/plat-s3c24xx/dma.cBen Dooks
Fix unused code warning in arch/arm/plat-s3c24xx/dma.c if there is no PM support enabled. The function to_dma_chan() should be marked inline so that the compiler will eliminate it without warning if it isn't used. arch/arm/plat-s3c24xx/dma.c:1239: warning: 'to_dma_chan' defined but not used Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-04-17[ARM] S3C: Fix ADC driver sparse warningBen Dooks
The symbol 's3c_adc_try' in arch/arm/plat-s3c24xx/adc.c does not need to be exported and thus should be static. This fixes the following sparse warning: adc.c:103:6: warning: symbol 's3c_adc_try' was not declared. Should it be static?

2009-03-19[ARM] pass reboot command line to arch_reset()Russell King
OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

2009-03-10[ARM] S3C: Tidy sleep code path to fix call flowBen Dooks
As noted by Russell King, the sleep code path is not elegant and makes use of leaving items on the stack between calls. Change the code that does the following: if (s3c_cpu_save(regs_save) == 0) { flush_cache_all(); S3C_PMDBG("preparing to sleep\n"); pm_cpu_sleep(); } to simply call s3c_cpu_save, and let that do the necessary calls to quiesce and sleep the system.

2009-03-08[ARM] S3C: Update UART save over PM suspend/resumeBen Dooks
Change the way the UART state is saved over suspend to allow the s3c64xx code to modify the settings on resume to avoid any illegal state changes to the UART clocks. This will also allow us to save the UDIVSLOT register on newer SoCs. Move to using a structure for the UART use the extant Kconfig configuration specifying the number of UARTs.

2009-03-08[ARM] S3C: Rename sleep.S functions to be non-cpu specificBen Dooks
Rename s3c2410_cpu_resume to s3c_cpu_resume and s3c2410_cpu_save to s3c_cpu_save to remove the CPU specific naming of these functions which are now in the generic PM code. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Rename s3c2410_pm_init to s3c_pm_init.Ben Dooks
Since we have moved a large proportion of the PM code to the common support area, remove the cpu specific name from the initialisation function. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Make IRQ_EINT sleep control commonBen Dooks
Move the IRQ_EINT sleep control to be available to all s3c impelmentations. Since s3c_irqext_wake is not large, place it in arch/arm/plat-s3c/pm.c as adding it to a new file would be a waste of compile time. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-03-08[ARM] S3C: Split the resume memory check code from pm.cBen Dooks
Split the optional memory check code out of the pm.c file as it is quite a big #ifdef block and as-such can be moved out and simply compiled when the configuration is set. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-03-08[ARM] S3C: Move PM support functions to common locationBen Dooks

2008-12-16[ARM] S3C: Update time initialisation to fix S3C64XX time problemsBen Dooks
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>
2008-12-16[ARM] S3C64XX: Update TCFG for new timer divider settings.Ben Dooks
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.

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] 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.

2008-12-15[ARM] S3C24XX: Change clock locking to use spinlocks.Ben Dooks

2008-12-15[ARM] S3C24XX: Split DCLK/CLKOUT definitions out of clock.cBen Dooks
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>
2008-12-15[ARM] S3C24XX: Move initialisation code to arch/arm/plat-s3cBen Dooks
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>
