2010-10-18ARM: S5P64X0: Add UART serial support for S5P6450Kukjin Kim1-1/+1
This patch adds UART serial port support for S5P6450 SoC. The S5P6450 has 6 UARTs, so adds resource of UART4 and UART5. And to fix membase which is in serial/samsung.c is from Ben Dooks. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com> Cc: Ben Dooks <ben-linux@fluff.org>
2010-08-05ARM: SAMSUNG: serial: Add FRACVAL support for newer UARTJongpill Lee1-2/+7
Add support for the FRACVAL register on the newer UART blocks which provides the same function as UDIVSLOT register but the FRACVAL is easier to implement. To support UDIVSLOT register, UDIVSLOT table search is necessary though supporting FRACVAL only needs the index value of UDIVSLOT table.

2010-01-19ARM: SAMSUNG: serial: Modify console initialization.Thomas Abraham1-3/+3
This patch modifies s3c24xx_serial_initconsole function to accept multiple platform UART information structures. This is required on platforms that have differences among the instances of UART ports. As an example, the FIFO sizes could be different for each UART instance and hence multiple platform UART information structures would be needed. This patch also modifies the s3c24xx_console_init macro since it wraps the call to the s3c24xx_serial_initconsole function.

There are a number of statements of the form A, B or A, B, C where the numbers A,B,C are not consecutive. However, referencing [1] it is the correct thing to replace these with A-B or A-C as apropriate.

2009-04-15[ARM] 5449/1: S3C: Use disable_irq_nosync() to fix boot lockupsMark Brown1-2/+2
With 2.6.30-rc1 on SMDK6410 I experience a soft lockup on bootup when the Samsung serial driver attempts to disable the transmit interrupt from within the transmit interrupt handler: it calls disable_irq() which locks up due to attempting to synchronise with the running handler. Fix this by using disable_irq_nosync(). Also make the same change in the recieve path.

First move of items out of include/asm-arm/plat-s3c* to their new homes under arch/arm/plat-s3c/include/plat and arch/arm/plat-s3c24xx/include/plat directories.

2008-07-03[ARM] S3C24XX: Split serial driver into core and per-cpu driversBen Dooks1-0/+1317
The S3C2410 serial driver in drivers/serial/s3c2410.c has been growing bigger with the addition of more variants of this hardware with the growing Samsung SoCs range. As such, it would be easier to split this code up into a core and per-cpu drivers to make driver addition easier, and the core smaller. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
