With the upcoming WDT patches OMAP_WDT_BASE is no longer needed in devices.c. Revert some earlier omap3 changes to avoid merge conflicts with the WDT patches. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-10-14[ARM] 5305/1: ARM: OMAP: Fix compile of McBSP by removing unnecessary checkTony Lindgren
Recent McBSP patches changed to allocating devices dynamically and the check for OMAP_MAX_MCBSP_COUNT became unnecessary. The check for OMAP_MAX_MCBSP_COUNT should have been removed with the earlier McBSP patches in devices.c but was accidentally left out.

2008-10-09ARM: OMAP3: Add minimal omap3430 supportSyed Mohammed, Khasim
Add minimal omap3430 support based on earlier patches from Syed Mohammed Khasim. Also merge in omap34xx SRAM support from Karthik Dasu and use consistent naming for sram init functions. Also do following changes that make 34xx support usable: - Remove unused sram.c functions for 34xx - Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally in entry-macro.S - Update mach-omap2/io.c to support 2420, 2430, and 34xx - Also merge in 34xx GPMC changes to add fields wr_access and wr_data_mux_bus from Adrian Hunter - Remove memory initialization call omap2_init_memory() until until more generic memory initialization patches are posted. It's OK to rely on bootloader initialization until then.

2008-10-08Fix sections for omap-mcbsp platform driverUwe Kleine-König
Don't use __init but __devinit to define probe function. A pointer to omap_mcbsp_probe is passed to the core via platform_driver_register and so the function must not disappear when the init code is freed. Using __init and having HOTPLUG=y the following probably oopses: echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/unbind echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/bind While at it move the remove function to the .devexit.text section.

2008-10-06ARM: OMAP2: Move sleep.S into sleep24xx.STony Lindgren
Some register offsets are different for 242x and 243x. This will allow compiling sleep code for both chips into the same kernel. Pass the addresses for SDRC_DDLA_CTRL and SDRC_POWER to the omap24xx_cpu_suspend instead of loading the values since the only. Also fix a bug to call omap2_sram_suspend with the value of SDRC_DLLA_CTRL instead of the address as that's what omap24xx_cpu_suspend expects to determine between DDR and SDR. This bug has not been noticed as the boards seem to have DDR instead of SDR. Note that some PM patches are still missing. The PM patches will be added later on once the base files are in sync with linux-omap tree. Signed-off-by: Tony Lindgren <tony@atomide.com>

OMAPs MMC device data was passing the wrong structure via the platform device.

2008-09-05[ARM] omap: fix inappropriate casting in gpio.cRussell King
gpio.c wilfully casts physical addresses to void __iomem * and then fixes them up at runtime using: bank->base = IO_ADDRESS(bank->base); where accesses prior to this fixup are via omap_read/omap_write, and after are by __raw_read/__raw_write. This doesn't lend itself to static checking, nor to easy understanding of the code. And so, OMAP_MPUIO_BASE gets to be the right type - integer like since it's a physical address, not a MMIO pointer.

2008-09-05[ARM] omap: Fix IO_ADDRESS() macrosRussell King
OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies for use with __raw_{read|write}* for accessing registers. Therefore, these macros should return (void __iomem *) cookies, not integer values. Doing this improves typechecking, and means we can find those places where, eg, DMA controllers are incorrectly given virtual addresses to DMA to, or physical addresses are thrown through a virtual to physical address translation.

2008-08-21[ARM] OMAP3 pwrdm: add hardware save-and-restore (SAR) supportPaul Walmsley
OMAP3430ES2+ introduces a new feature: optional powerdomain context hardware save-and-restore (SAR). Currently, this feature only applies to USBHOST and USBTLL module context when the USBHOST or CORE powerdomains enter a low-power sleep state[1]. This feature avoids re-enumeration of USB devices when the powerdomains return from idle, which is potentially time-consuming. This patch adds support for enabling and disabling hardware save-and-restore to the powerdomain code. Three new functions are added, pwrdm_enable_hdwr_sar(), pwrdm_disable_hdwr_sar(), and pwrdm_can_hdwr_sar(). A new struct powerdomain "flags" field is added, with a PWRDM_HAS_HDWR_SAR flag to indicate powerdomains with SAR support. Thanks to Jouni Högander <jouni.hogander@nokia.com> for reviewing an earlier version of these patches, and Richard Woodruff <r-woodruff2@ti.com> for clarifying the purpose of these bits. 1. For the USBHOST controller module, context loss occurs when the USBHOST powerdomain enters off-idle. For USBTLL, context loss occurs either if CORE enters off-idle, or if the CORE logic is configured to turn off when CORE enters retention-idle (OSWR). 34xx ES2 TRM 4.8.6.1.1, 4.8.6.1.2 Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-08-19ARM: OMAP2: Clockdomain: Add base OMAP2/3 clockdomain codePaul Walmsley
This patch creates an interface to the clockdomain registers in the PRM/CM modules on OMAP2/3. This interface is intended to be used by PM code, e.g., pm.c; not by device drivers directly. The patch also adds clockdomain usecount tracking. This is intended to be called whenever the first clock in a clockdomain is enabled, or when the last enabled clock in a clockdomain is disabled. If the clockdomain is in software-supervised mode, the code will force-wakeup or force-sleep the clockdomain. If the clockdomain is in hardware-supervised mode, the first clock enable will add sleep and wakeup dependencies on a user-selectable set of parent domains (usually MPU & IVA2), and the disable will remove them. Each clockdomain will be defined in later patches as static structures. The clockdomain structures are linked into a list at boot by clkdm_register(), similar to the OMAP clock code. The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which when enabled will emit verbose debug messages via pr_debug().

2008-08-10[ARM] dma-mapping: improve type-safeness of DMA translationsRussell King
OMAP at least gets the return type(s) for the DMA translation functions wrong, which can lead to subtle errors.
