* ARM: S3C2410: Fix sparse warnings in arch/arm/mach-s3c2410/gpio.cBen Dooks2009-10-28
| | | | | | | | | Fix sparse warning in arch/arm/mach-s3c2410/gpio.c due to missing include of <mach/gpio-fns.h>. Fixes the following warning: warning: symbol 's3c2410_gpio_irqfilter' was not declared. Should it be static? Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* ARM: S3C: Add info for supporting circular DMA buffersBen Dooks2009-10-28
| | | | | | | | | | | | | | | The S3C64XX DMA implementation will work a lot better with the ability to enqueue circular buffers as the hardware can do it's own linked-list management. Add a function s3c_dma_has_circular() to show that the system can do this and a flag for the channel. Update the s3c24xx/s3c64xx I2S DMA code to deal with this.

* ARM: S3C: Add missing selection of S3C_DEV_NAND in machine Kconfigs.Ben Dooks2009-09-17

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.

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.
