USB Host on OMAP3 EVM, 2.6.29

Hi, We're trying to get basic USB host mode up and running on a OMAP3530 EVM, with no success. We're (now, after many permutations of kernels and .config settings) using the vanilla 2.6.29-omap1 kernel plus the AUTOIDLE fix from Niilo Minkkinen), with slight additions to board-omap3evm to al

Please advise on choosing the right backlight switching framework

Hi, I'd like to add support for lcd backlight on/off switching on omap1 ams-delta board. I could potentially use omap1_bl backlight class device driver for this purpose, but it is not fully compatible with ams-delta, as it actually changes lcd contrast instead of backlight intensity on this boa

[PATCH 09/10] OMAP3 clock: GPIO de-bounce clocks don't affect module idle state

[PATCH 08/10] OMAP3 SDRC: set FIXEDDELAY when disabling SDRC DLL

Correspondence with the TI OMAP hardware team indicates that SDRC_DLLA_CTRL.FIXEDDELAY should be initialized to 0x0f. This number was apparently derived from process validation. This is only used when the SDRC DLL is unlocked (e.g., SDRC clock frequency less than 83MHz). Signed-off-by: Paul Walm

[PATCH 04/10] OMAP3 clock/SDRC: program SDRC_MR register during SDRC clock change

Program the SDRC_MR_0 register as well during SDRC clock changes. This register allows selection of the memory CAS latency. Some SDRAM chips, such as the Qimonda HYB18M512160AF6, have a lower CAS latency at lower clock rates. Signed-off-by: Paul Walmsley --- arch/arm/mach-omap2/clock34xx.c

[PATCH 03/10] OMAP3 clock: add a short delay when lowering CORE clk rate

When changing the SDRAM clock from 166MHz to 83MHz via the CORE DPLL M2 divider, add a short delay before returning to SDRAM to allow the SDRC time to stabilize. Without this delay, the system is prone to random panics upon re-entering SDRAM. This time delay varies based on MPU frequency. At 500
