2009-07-29S3C24XX: GPIO: Fix pin range check in s3c_gpiolib_getchipLars-Peter Clausen1-1/+1
In the s3c_gpiolib_getchip implementation for s3c24xx the check whether a pin is in the gpio banks range is reversed. Thus the function returns NULL for valid pins and the gpio chip if its not valid. As a result gpio states are not saved/restored properly during suspend/resume. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-05-18[ARM] S3C24XX: GPIO: Change to macros for GPIO numberingBen Dooks14-193/+92
Prepare to remove the large number of S3C2410_GPxn defines by moving to S3C2410_GPx(n) in arch/arm. The following perl was used to change the files: perl -pi~ -e 's/S3C2410_GP([A-Z])([0-9]+)([^_^0-9])/S3C2410_GP\1\(\2\)\3/g' Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-18[ARM] S3C24XX: GPIO: Add S3C64XX style GPIO numberingBen Dooks1-0/+49
Move the new style of GPIO numbering by using a single macro for each GPIO bank. This means S3C2410_GPA0 becomes S3C2410_GPA(0), and so on. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-18[ARM] S3C24XX: GPIO: Clean out unused definitions in <mach/regs-gpio.h>Ben Dooks1-211/+0
The <mach/regs-gpio.h> really does not need the input and output pin configurations as these are standard and have a generic representation (plus the s3c24xx gpio specific code is going to be phased out soon). The following sed was applied to remove the lines: sed -i~ -e '/S3C2410_GP[A-Z][0-9]*_\INP/d' \ -e '/S3C2410_GP[A-Z][0-9]*_\OUTP/d' \ -e '/S3C2410_GPA[0-9]*_OUT/d' to remove these.

2009-05-18[ARM] S3C24XX: GPIO: Move gpio functions out of <mach/hardware.h>Ben Dooks11-84/+113
Move all the gpio functions out of <mach/hardware.h> as this file is for defining the generic IO base addresses for the kernel IO calls. Make a new header <mach/gpio-fns.h> to take this and include it via the chain from <linux/gpio.h> which is what most of these files should be using (and will be changed as soon as possible). Note, this does make minor changes to some drivers but should not mess up any pending merges.

Move the watchdog reset code from <mach/system-reset.h> to a new file <plat/watchdog-reset.h> as this code is needed by both s3c2410, s3c64xx and soon-to-be added s3c24a0. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-17[ARM] S3C24XX: GPIO: Remove pin specific input and output definesBen Dooks5-5/+5
The use of S3C2410_GP[A-Z]x_INP and S3C2410_GP[A-Z]x_OUTP are very rare and are taking up large amounts of space in the regs-gpio.h header. The GPIO layer has had generic input and out defines called S3C2410_GPIO_INPUT and S3C2410_GPIO_OUTPUT for a while which work for all S3C24XX GPIOs. Do the following replacements: S3C2410_GP[A-Z][0-9]*_\OUTP => S3C2410_GPIO_OUTPUT S3C2410_GP[A-Z][0-9]*_\INP => /S3C2410_GPIO_INPUT S3C2410_GPA[0-9]*_OUT => S3C2410_GPIO_OUTPUT to remove any usages of these and prepare the header for the removal of these. The following command was used to acheive this: find . -type f -writable ! -name regs-gpio.h ! -name "*~" | xargs sed -i~ -e 's/S3C2410_GP[A-Z][0-9]*_\OUTP/S3C2410_GPIO_OUTPUT/g' -e 's/S3C2410_GP[A-Z][0-9]*_\INP/S3C2410_GPIO_INPUT/g' -e 's/S3C2410_GPA[0-9]*_OUT/S3C2410_GPIO_OUTPUT/g' Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-17[ARM] S3C24XX: GPIO: Remove s3c2410_gpio_irq2pin() callBen Dooks1-11/+0
Remove the s3c2410_gpio_irq2pin() function as it is not being used in any in kernel driver and the function is probably not being used anywhere else. This is also part of the effort to remove any of the s3c24xx gpio specific code that cannot be recreated by using the gpiolib framework now in the kernel.

2009-05-15[ARM] S3C2410: mach-bast.c registering i2c data too earlyBen Dooks1-2/+1
The BAST support code is calling s3c_i2c0_set_platdata() from the map_io() entry, instead of the bast_init() code. This causes the registration to fail due to kmalloc() not being available at the time. This fixes the following error: s3c_i2c0_set_platdata: no memory for platform data Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-05-01[ARM] S3C24XX: dma.h should not include <mach/hardware.h>Ben Dooks2-1/+1
The dma.h header does not need to include <mach/hardware.h> as there is nothing it depends on. Remove the include and fixup the couple of places where <mach/map.h> was not explicitly included (dragged in via <mach/hardware.h>) Note, we have to fix arch/arm/plat-s3c24xx/pm.c which seems to rely on having <mach/hardware.h> included by this method.

2009-05-01[ARM] S3C24XX: Remove hardware specific registers from DMABen Dooks1-3/+3
calls The S3C24XX DMA API channel configuration registers are being passed values comprised of register values which makes it hard to move the API to cover both the S3C24XX and S3C64XX. These values can be calculated from knowing which device the channel is connected to, so remove them from the two calls s3c2410_dma_config and s3c2410_dma_devconfig.

2009-04-07i2c-s3c2410: Simplify bus frequency calculationDaniel Silverstone2-4/+2
The platform data for the i2c-s3c2410 driver used to allow a min, max and desired frequency for the I2C bus. This patch reduces it to simply a desired frequency ceiling and corrects all the uses of the platform data appropriately. This means, for example, that on a system with a 66MHz fclk, a request for 100KHz will achieve 65KHz which is safe and acceptable, rather than 378KHz which it would have achieved without this change.

2009-03-19[ARM] pass reboot command line to arch_reset()Russell King1-1/+1
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.

Add the definition for S3C_GPIO_END to allow the PM code to build. This means moving the GPIO bank numbers to a separate file to allow the gpio and regs-gpio to include them.
