2009-08-20OMAP: McBSP: Wakeups utilizedEero Nurkkala
This patch enables the smart idle mode while McBPS is being utilized. Once it's done, force idle mode is taken instead. Apart of it, it also configures what signals will wake mcbsp up.

2009-08-20OMAP: McBSP: Add link DMA mode selectionPeter Ujfalusi
It adds a new sysfs file, where the user can configure the mcbsp mode to use. If the mcbsp channel is in use, it does not allow the change. Than in omap_pcm_open we can call the omap_mcbsp_get_opmode to get the mode, store it, than use it to implement the different modes.

2009-08-20OMAP: McBSP: Rename thres sysfs symbolsEduardo Valentin
This patch renames the symbols that handles threshold sysfs properties. This way we can add more sysfs properties to them. Signed-off-by: Eduardo Valentin <eduardo.valentin@nokia.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-08-20OMAP3: McBSP: Lower the maximum buffersize for McBSP1, 3, 4, 5Peter Ujfalusi
Do not allow applications to use the full buffer found on McBSP1,3,4,5. Using the full buffer in threshold mode causes the McBSP buffer to run dry, which can be observed as channels are switching (in reality the channels are shifting).

2009-08-20OMAP: McBSP: Create and export max_(r|t)x_thres propertyEduardo Valentin
This patch export through sysfs two properties to configure maximum threshold for transmission and reception on each mcbsp instance. Also, it exports two helper functions to allow mcbsp users to read this values.

2009-08-20OMAP: McBSP: Use appropriate value for startup delayEduardo Valentin
Increasing startup delay value as worst case: CLKSRG*2 = 8000khz: (1/8000) * 2 * 2 usec Although, 100us may give enough time for two CLKSRG, due to some unknown PM related, clock gating etc. reason, this patch increases it to 500us.

2009-08-20OMAP: McBSP: Provide functions for ASoC frame syncronizationEero Nurkkala
ASoC has an annoying bug letting either L or R channel to be played on L channel. In other words, L and R channels can switch at random.

2009-08-17ARM: Show FIQ in /proc/interrupts on CONFIG_FIQBen Dooks
The show_fiq_list() call in arch/arm/kernel/irq.c currently depends on CONFIG_ARCH_ACORN, but this is not the only architecture that supports the usage of FIQ. Change to calling this if CONFIG_FIQ is set (which is what arch/arm/kernel/fiq.c is built by). Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-08-16ARM: S3C: Add S3C_DEV_NAND Kconfig entryBen Dooks
Currently the S5PC100 does not define S3C_PA_NAND, leaving the NAND device definitions in arch/arm/plat-s3c/dev-nand.c unbuildable. Add a KConfig entry to select whether this is built. As backwards compatibility, both the S3C24XX and S3C64XX define the new configuration in their main Kconfig files until better support for basing this selection on a per-machine basis can be sorted out.

2009-08-16ARM: S5PC100: Kconfigs and MakefilesByungho Min
S5PC100 is a new SoC with ARM coretex-A8 and numerous peripherals. This SoC is successor of S3C64XX. S5PC100 has peripherals which are still similar to S3C families so some drivers in "arch/arm/plat-s3c" can be shared. S5PC100 specific drivers will be added in "arch/arm/plat-s5pcxx" or "arch/arm/mach-s5pc100" Signed-off-by: Byungho Min <bhmin@samsung.com> [ben-linux@fluff.org: tidy and edit description] Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-08-16ARM: S5PC100: Clock and PLL supportByungho Min

2009-08-16ARM: S5PC100: IRQ and timerByungho Min
S5PC100 has 3 VICs(Vectored Interrupt Controller). The VICs come from S3C64xx series, so the driver source code can be shared with S3C families. The S5PC100 has 3 VICs while S3C64xx has only 2.

2009-08-16ARM: S5PC100: UART and SerialByungho Min
Serial driver of S5PC100 is the same as S3C6400, so S5PC100 shares the serial driver with S3C6400. Uart driver is copied from plat-s3c64xx to plat-s5pc1xx, as I do not use plat-s3c64xx directory.

S5PC100's the physical IO space starts at 0xe000"0000. To maximize space for vmalloc, the virtual IO space starts at 0xf400"0000 as same as other samsung CPUs(s3c24xx and s3c64xx) do.
