2009-05-18[ARM] S3C24XX: GPIO: Change to macros for GPIO numberingBen Dooks
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 Dooks
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: Start removal of S3C24XX_GPIO_BASEBen Dooks
The S3C24XX_GPIO_BASE makes it difficult to compress the GPIO number space, and is only used in a few places of which everything outside arch/arm/plat-s3c24xx/gpiolib.c will be removed as soon as possible. Change gpiolib.c to use the S3C2410_GPxCON register addresses as the base for each bank, thus eliminating S3C24XX_GPIO_BASE. 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 Dooks
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: Fix missing <linux/sysdev.h>Ben Dooks
In our recent changes, arch/arm/plat-s3c24xx/gpiolib.c needs to have <linux/sysdev.h> included for it to build. This fixes the following error/warnings: arch/arm/plat-s3c/include/plat/pm.h:104: error: expected declaration specifiers or '...' before 'pm_message_t' arch/arm/plat-s3c/include/plat/pm.h:104: warning: 'struct sys_device' declared inside parameter list arch/arm/plat-s3c/include/plat/pm.h:104: warning: its scope is only this definition or declaration, which is probably not what you want arch/arm/plat-s3c/include/plat/pm.h:105: warning: 'struct sys_device' declared inside parameter list Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-18[ARM] S3C24XX: GPIO: Move gpio functions out of <mach/hardware.h>Ben Dooks
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.

2009-05-17[ARM] S3C24XX: GPIO: Remove pin specific input and output definesBen Dooks
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 Dooks
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.

2009-05-07[ARM] VIC: Add power management deviceBen Dooks
Add power management support to the VIC by registering each VIC as a system device to get suspend/resume events going. Since the VIC registeration is done early, we need to record the VICs in a static array which is used to add the system devices later once the initcalls are run. This means there is now a configuration value for the number of VICs in the system. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C: GPIO PM core GPIOlib integrationBen Dooks
Move the GPIO suspend/resume support inline with the gpiolib support so that it will work with both the S3C24XX and S3C64XX series. The s3c_gpio_chip is extended to have a pm callback and a save block to keep the state of the GPIO over suspend, and the code from the s3c24xx implementation is added to a new common file. The suspend process now uses the list of registered chips to go through saving and restoring each one as appropriate, using the pm callback to select the appropriate routine depending on the type of control register present. This change also means that any additional GPIO added should not require changes to the PM. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C64XX: Add IRQ PM codeBen Dooks
Add support for saving the state of the IRQ registers over suspend. This requires moving the S3C64XX UART registers into <plat/regs-serial.h> and adding irq-pm.c which saves the state of all the IRQ registers. The irq-pm.c saves all the IRQ registers, including the IRQ_EINT and IRQ_EINT_GROUP registers as it was easier than adding three different files. Also ensuring that all the registers are restored to the same state as before suspend is considered to be the best thing to do. Note, we do not suspend the VIC here, this is done by the VIC driver itself. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C64XX: Add generic s3c64xx sys device.Ben Dooks
Add an s3c64xx_sysclass and device for items that currently want to bind to any s3c64xx processor. The first user of this will be parts of the s3c64xx suspend support which need to save device state over suspend/resume. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-04-23[ARM] 5460/1: Orion: reduce namespace pollutionNicolas Pitre
Symbols like SOFT_RESET are way too generic to be exported at large. To avoid this, let's move the mbus bridge register defines into a separate file and include it where needed. This affects mach-kirkwood, mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all share code in plat-orion which relies on those defines. Some other defines have been moved to narrower scopes, or simply deleted when they had no user. This fixes compilation problem with mpt2sas on the above listed platforms.

These syscalls simply take five long-sized parameters, so they should have no calling-convention/ABI issues in the kernel. Tested on armv5tel eabi using a preadv/pwritev test program posted on linuxppc-dev earlier this month. It would be nice to get this into the kernel before 2.6.30 final, so that glibc's kernel version feature test for these syscalls doesn't have to special-case ARM.
