* omap mmc: Add low-level initialization for hsmmc controllerTony Lindgren2008-12-101-5/+10
| | | | | | | | | | | | | | | | | | | | | | | Add low-level initialization for hsmmc controller. Merged into this patch patch are various improvments and board support by Grazvydas Ignotas and David Brownell. Also change wire4 to be wires, as some newer controllers support 8 data lines.

* ARM: OMAP3: Add minimal omap3430 supportSyed Mohammed, Khasim2008-10-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ARM: OMAP2: Move sleep.S into sleep24xx.STony Lindgren2008-10-061-1/+4
| | | | | | | | | | | | | | | | | | 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>
* ARM: OMAP2: Clockdomain: Add base OMAP2/3 clockdomain codePaul Walmsley2008-08-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* ARM: OMAP2: Powerdomain: Add base OMAP2/3 powerdomain codePaul Walmsley2008-08-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch creates an interface to the powerdomain 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. Each powerdomain will be defined in later patches as static structures. Also defined are dependencies between powerdomains, used for adding and removing PM_WKDEP and CM_SLEEPDEP bits. The powerdomain structures are linked into a list at boot by pwrdm_register(), similar to the OMAP clock code. The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_POWERDOMAIN, which when enabled will emit verbose debug messages via pr_debug().

| | | | | | | | | | | | | | | | | This patch changes 24xx to use shared clock code and new register access. Note that patch adds some temporary OLD_CK defines to keep patch more readable. These temporary defines will be removed in the next patch. Also not all clocks are changed in this patch to limit the size. Also, the patch fixes few incorrect clock defines in clock24xx.h.

* ARM: OMAP: Timer32K: Re-organize duplicated 32k-timer codeKevin Hilman2008-04-141-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | On OMAP2/3, the gp-timer code can be used for a 32kHz timer simply by setting the source to be the 32k clock instead of sys_clk. This patch uses the mach-omap2/timer-gp.c code for 32kHz timer on OMAP2, moving the logic into mach-omap2/timer-gp.c, and not using plat-omap/timer32k.c which, for OMAP2, is redundant with the timer-gp code. Also, if CONFIG_OMAP_32K_TIMER is enabled, the gptimer-based clocksource is not used. Instead the default 32k sync counter is used as the clocksource (see the clocksource in plat-omap/common.c.) This is important for sleep/suspend so there is a valid counter during sleep. Note that the suspend/sleep code needs fixing to check for overflows of this counter. In addition, the OMAP2/3 details are removed from timer32k.c leaving that with only OMAP1 specifics. A follow-up patch will move it from plat-omap common code to mach-omap1.

* [ARM] 3145/1: OMAP 3a/5: Add support for omap24xxTony Lindgren2005-11-101-0/+13
Patch from Tony Lindgren This patch adds support for omap24xx series of processors. The files live in arch/arm/mach-omap2, and share common files with omap15xx and omap16xx processors in arch/arm/plat-omap. Omap24xx support was originally added for 2.6.9 by TI. This code was then improved and integrated to share common code with omap15xx and omap16xx processors by various omap developers, such as Paul Mundt, Juha Yrjola, Imre Deak, Tony Lindgren, Richard Woodruff, Nishant Menon, Komal Shah et al.
