* ARM: OMAP3: Initialize regulators for Beagle and OveroDavid Brownell2009-05-281-9/+95
| | | | | | | | | | Initialize regulators for Beagle and Overo. Patch is based on earlier patches posted to linux-omap mailing list. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP3: SDRC: add timing data for Micron MT46H32M32LF-6, v2Paul Walmsley2009-05-281-1/+3
| | | | | | | | | | | | | | Add timing data for the Micron MT46H32M32LF-6 SDRAM chip, used on the OMAP3 Beagle and EVM boards. Original timing data is from the Micron datasheet PDF downloaded from: http://download.micron.com/pdf/datasheets/dram/mobile/1gb_ddr_mobile_sdram_t48m.pdf Thanks to Rajendra Nayak <rnayak@ti.com> for his help identifying the chips used on Beagle & OMAP3EVM.

* OMAP2/3 GPTIMER: allow system tick GPTIMER to be changed in board-*.c filesPaul Walmsley2009-04-231-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files to use in .init_irq functions to configure the system tick GPTIMER. Practical choices at this point are GPTIMER1 or GPTIMER12. Both of these timers are in the WKUP powerdomain, and so are unaffected by chip power management. GPTIMER1 can use sys_clk as a source, for applications where a high-resolution timer is more important than power management. GPTIMER12 has the special property that it has the secure 32kHz oscillator as its source clock, which may be less prone to glitches than the off-chip 32kHz oscillator. But on HS devices, it may not be available for Linux use. It appears that most boards are fine with GPTIMER1, but BeagleBoard should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs in revisions B4 and below. Modify board-omap3beagle.c to use GPTIMER12. This patch originally used a Kbuild config option to select the GPTIMER, but was changed to allow this to be specified in board-*.c files, per Tony's request. Kalle Vallo <kalle.valo@nokia.com> found a bug in an earlier version of this patch - thanks Kalle. Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and 3430SDP.

| | | | | | | | | | | | | | | | | | | | | | | | | | Changing it do 100kHz is needed to make more devices works properly. Controlling the TI DLP Pico projector[1] doesn't work properly at 400kHz, 100kHz and lower work fine. EDID readout is unaffected by this change.

* | [ARM] OMAP2 SDRC: add SDRAM timing parameter infrastructurePaul Walmsley2009-02-081-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | For a given SDRAM clock rate, SDRAM chips require memory controllers to use a specific set of timing minimums and maximums to transfer data reliably. These parameters can be different for different memory chips and can also potentially vary by board. This patch adds the infrastructure for board-*.c files to pass this timing data to the SDRAM controller init function. The timing data is specified in an 'omap_sdrc_params' structure, in terms of SDRC controller register values. An array of these structs, one per SDRC target clock rate, is passed by the board-*.c file to omap2_init_common_hw(). This patch does not define the values for different memory chips, nor does it use the values for anything; those will come in subsequent patches. linux-omap source commit is bc84ecfc795c2d1c5cda8da4127cf972f488a696.
