2009-12-11omap1: DMA: move LCD related code from plat-omap to mach-omap1Janusz Krzysztofik
All of the LCD DMA code in plat-omap/dma.c appears to be OMAP1-only (and apparently only is available on a subset of OMAP1 chips). Move this code to mach-omap1/lcd_dma.c.

Add new style mux data for 34xx. This should also work with 3630 easily by adding the processor subset and ball data. Note that this data is __initdata, and gets optimized out except for the GPIO pins if CONFIG_OMAP_MUX is not set. Also note that this data uses omap3630 naming for the SDMMC registers instead of 34xx naming with just MMC.

2009-12-11OMAP3 hwmod: drop most of the OCP_SYSCONFIG.CLOCKACTIVITY codePaul Walmsley
Earlier, the hwmod code had considered the OCP_SYSCONFIG.CLOCKACTIVITY bits to be incremental power saving bits, controlling internal IP block clock gates. This was a misapprehension. The CLOCKACTIVITY bits are used to indicate, in advance, which clocks will be cut when the module acknowledges an idle request. This enables the IP block to take whatever action is necessary to complete any in-progress work before asserting its IdleAck. In the current Linux-OMAP code, this implies that the clock framework should be changing module CLOCKACTIVITY bits as module clocks are enabled and disabled. We don't do that yet, but in the future, we should. This must wait until the clock tree is annotated with omap_hwmod pointers (or vice-versa). In the meantime, drop most of the hwmod code that controls CLOCKACTIVITY bits to avoid confusion. This patch has benefited from many illuminating discussions with (in alphabetical order) Benoît Cousson <b-cousson@ti.com>, Rajendra Nayak <rnayak@ti.com>, and Sebastien Sabatier <s-sabatier1@ti.com>.

2009-12-11OMAP hwmod: add names to module MPU IRQ linesPaul Walmsley
Replace the existing u8 array of module MPU IRQ lines with a struct that includes a name - similar to the existing struct omap_hwmod_dma_info. Device drivers can then use platform_get_resource_byname() to retrieve specific IRQs without nasty dependencies on array ordering.

2009-12-11OMAP3 hwmod: Add automatic OCP_SYSCONFIG AUTOIDLE handlingPaul Walmsley
This patch fills in the OCP_SYSCONFIG.AUTOIDLE handling in the OMAP hwmod code. After this patch, the hwmod code will set the module AUTOIDLE bit (generally <module>.OCP_SYSCONFIG.AUTOIDLE) to 1 by default upon enable. If the hwmod flag HWMOD_NO_OCP_AUTOIDLE is set, AUTOIDLE will be set to 0 upon enable. Upon module disable, AUTOIDLE will be set to 1. Enabling module autoidle should save some power. The only reason to not set the OCP_SYSCONFIG.AUTOIDLE bit is if there is a bug in the module RTL, e.g., the MPUINTC block on OMAP3. Comments from Kevin Hilman <khilman@deeprootsystems.com> inspired this patch, and Kevin tested an earlier version of this patch.

2009-12-11OMAP3: SDRC: Place SDRC AC timing and MR changes in CORE DVFS SRAM code ↵Paul Walmsley
behind Kconfig The code that reprograms the SDRC memory controller during CORE DVFS, mach-omap2/sram34xx.S:omap3_sram_configure_core_dpll(), does not ensure that all L3 initiators are prevented from accessing the SDRAM before modifying the SDRC AC timing and MR registers. This can cause memory to be corrupted or cause the SDRC to enter an unpredictable state. This patch places that code behind a Kconfig option, CONFIG_OMAP3_SDRC_AC_TIMING for now, and adds a note explaining what is going on. Ideally the code can be added back in once supporting code is present to ensure that other initiators aren't touching the SDRAM. At the very least, these registers should be reprogrammable during kernel init to deal with buggy bootloaders. Users who know that all other system initiators will not be touching the SDRAM can also re-enable this Kconfig option. This is a modification of a patch originally written by Rajendra Nayak <rnayak@ti.com> (the original is at http://patchwork.kernel.org/patch/51927/). Rather than removing the code completely, this patch just comments it out. Thanks to Benoît Cousson <b-cousson@ti.com> and Christophe Sucur <c-sucur@ti.com> for explaining the technical basis for this and for explaining what can be done to make this path work in future code.

2009-12-11OMAP1 clock: convert test in disable_unused() to use ENABLE_ON_INITPaul Walmsley
mach-omap1/clock.c:omap1_clk_disable_unused() contains a test that assumes that the clock structures are available in the file's namespace. After a following patch, this will no longer be the case. So we need to reimplement that test. It turns out that we already have a facility in the clock framework to handle this case - the ENABLE_ON_INIT flag - used on OMAP2/3. Remove the offending test and mark the clocks that it was intended to catch as ENABLE_ON_INIT. Signed-off-by: Paul Walmsley <paul@pwsan.com>
