From d9295746c0ed3991bdec18c6a5890d71d88904b4 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 12 May 2009 17:27:09 -0600 Subject: OMAP3 SRAM: mark OCM RAM as Non-cacheable Normal memory Mark the SRAM (aka OCM RAM) as Non-cacheable Normal memory[1]. This is to prevent the ARM from evicting existing cache lines to SDRAM while code is executing from the SRAM. Necessary since one of the primary uses for the SRAM is to hold the code and data for the CORE DPLL M2 divider reprogramming code, which must execute while the SDRC is idled. If the ARM attempts to write cache lines back to the while the SRAM code is running, the ARM will stall[2]. TI deals with this problem in the CDP kernel by marking the SRAM as Strongly-ordered memory. Tero Kristo caught a bug in an earlier version of this patch - thanks Tero. ... 1.

The idea here is to force all delayed write traffic going to the SDRAM to at least post to the L3 interconnect before continuing. If these writes are allowed to occur after the SDRC is idled, the writes will not be acknowledged and the ARM will stall. Note that in this case, it does not matter if the writes actually complete to the SDRAM - it is only necessary for the writes to leave the ARM itself. If the writes are posted by the interconnect when the SDRC goes into idle, the writes will be delayed until the SDRC returns from idle[2]. If the SDRC is in the middle of a write when it is requested to enter idle, the SDRC will not acknowledge the idle request until the writes complete to the SDRAM.[3] The old-style DMB in sdram_in_selfrefresh is now superfluous, so, remove it. - Add an ISB before the function's exit point to prevent the ARM from speculatively executing into SDRAM before the SDRAM is enabled[4]. ... 1.

Also fold in a patch from Kevin Hilman to add _OFFSET #defines for the PRCM registers to be used with the prm_[read|write]_* macros. These are used extensively in the forthcoming OMAP PM support. Also remove now unused OMAP2_PRM_BASE.

Also fold in a patch from Kevin Hilman to add _OFFSET #defines for the PRCM registers to be used with the prm_[read|write]_* macros. These are used extensively in the forthcoming OMAP PM support. Also remove now unused OMAP2_PRM_BASE.

After the expiration of an activity timer, each UART is allowed to disable its clocks so the system can enter retention. The activity timer is (re)activated on any UART interrupt, UART wake event or any IO pad wakeup. The actual disable of the UART clocks is done in the 'prepare_idle' hook called from the OMAP idle loop. While the activity timer is active, the smart-idle mode of the UART is also disabled. This is due to a "feature" of the UART module that after a UART wakeup, the smart-idle mode may be entered before the UART has communicated the interrupt, or upon TX, an idle mode may be entered before the TX FIFOs are emptied. Upon suspend, the 'prepare_suspend' hook cancels any pending activity timers and allows the clocks to be disabled immediately. In addition, upon disabling clocks the UART state is saved in case of an off-mode transition while clocks are off. Special thanks to Tero Kristo for the initial ideas and first versions of UART idle support, and to Jouni Hogander for extra testing and bugfixes.

New sysfs entry is added (/sys/devices/platform/serial8250./sleep_timeout) Writing zero will disable the timeout feature and prevent UART clocks from being disabled. Also default timeout is increased to 5 second to make serial console more usable. Original patch was written by Tero Kristo.

This allows future recalculation of the timings when the source clock gets scaled. Also correct the rx51 interrupt to be IORESOURCE_IRQ_HIGHLEVEL. Thanks to Paul Walmsley for better GPMC timing calculations.

This makes the glue's "mmc-twl4030" name become a complete misnomer ... this code could probably all migrate into the HSMMC driver now. Tested on 3430SDP (SD and low-voltage MMC) and Beagle (SD), plus some other boards (including Overo) after they were converted to set up MMC regulators properly. Eventually all boards should just associate a regulator with each MMC controller they use. In some cases (Overo MMC2 and Pandora MMC3, at least) that would be a fixed-voltage regulator with no real software control. As a temporary hack (pending regulator-next updates to make the "fixed.c" regulator become usable) there's a new ocr_mask field for those boards.

The platform and machine specific headers and sources updated for OMAP4430 SDP platform. OMAP4430 is Texas Instrument's SOC based on ARM Cortex-A9 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency.

2009 14:16:04 -0700 Subject: ARM: OMAP4: Clock stubs since CLKDEV not in yet. This patch update the common clock.c file for OMAP4. The clk_get() and clk_put() functions are moved to common place in arch/arm/common/clkdev.c Since on current OMAP4 platform clk management is still not supported, the platform file is stubbed with those functions. Once the framework is ready, this WILL be replaced with a full clkdev implementation.
