* mfd: Rename twl4030* driver files to enable re-useSantosh Shilimkar2009-12-13
| | | | | | | | | | | | | | | The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030 for OMAP3. The common modules like RTC, Regulator creates opportunity to re-use the most of the code from twl4030. This patch renames few common drivers twl4030* files to twl* to enable the code re-use.

| | | | | | | | | | | | CM-T35 can be assembled with different set of peripherals thus making certain interfaces available to user as GPIOs or dedicated pins.

* OMAP3 hwmod: drop most of the OCP_SYSCONFIG.CLOCKACTIVITY codePaul Walmsley2009-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* OMAP3 hwmod: Add automatic OCP_SYSCONFIG AUTOIDLE handlingPaul Walmsley2009-12-11
| | | | | | | | | | | | | | | | | | | | | 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.

* OMAP3: SDRC: Place SDRC AC timing and MR changes in CORE DVFS SRAM code ↵Paul Walmsley2009-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
