Request two more GPIOs on Beagle: MMC write protect, DVI enable. Also define the first OMAP3 GPIO mux config symbols, with a new naming convention. Examples: - GPIO42 is bidirectional, and uses external pull up/down (if any); - GPIO42_UP is bidirectional, with an internal pullup; - GPIO42_DOWN is bidirectional, with an internal pulldown. - GPIO42_OUT is output-only, and needs no pullup or pulldown. All of those would be fully functional through the standard GPIO interface as well as the legacy OMAP-only one, except GPIO42_OUT which won't let you read the actual pin value after setting it. There's no special off-mode support for these particular pins; on Beagle they have external pullups or pulldowns. (OMAP2 can use this naming convention too, except that since it has no input-enable the "_OUT" convention can't be used there.) Signed-off-by:

OMAP2/3 clock: fix CONFIG_OMAP_RESET_CLOCKS plat-omap/clock.c was skipping clocks with enable_reg == 0. This no longer works now that we use enable_reg as an offset from a PRCM module. Problem found and traced by Tero Kristo <tero.kristo@nokia.com> - thanks Tero. Signed-off-by:

This increases VMALLOC_END to 0x18000000, making room for 256MB RAM with the default 128MB vmalloc region. Note that after this patch there's no longer a hole between vmalloc space and the beginning of IO space on omap2 as the first virtual mapping starts at 0xd8000000. Signed-off-by:

Make OMAP use the new __gpio_to_irq() hook, to make it easier to support IRQs coming in from off-chip gpio controllers like the TWL4030/TPS65930 chip used on OMAP3 boads like Beagleboard.org and the Gumstix Overo. Signed-off-by:

Add a new gpiolib mechanism: gpio_chip instances can provide mappings between their (input) GPIOs and any associated IRQs. This makes it easier for platforms to support IRQs that are provided by board-specific external chips instead of as part of their core (such as SOC-integrated GPIOs). Also update the irq_to_gpio() description, saying to avoid it becuase it's not always supported. Signed-off-by:

A variety of twl4030-core cleanups: - SIH register declarations moved from core.c to twl4030.h, for keypad, madc, bci; this decouples from twl4030-madc.h; add several omitted register decls; remove a duplicate. - Use a global "inuse" flag, not a per-slave one; - Remove pointless SLAVENUM_NUM symbols; just use 0/1/2/3 - Comments: * Add comments: header, register values * Add some section delimiters * Correct clock init and other comments - Minor stuff: * Group some variables and code with sibling * Make clock init a bit simpler * List twl5030 in supported i2c chips list * Remove needless "return;" And one IRQ-related bugfix: if the I2C timeout bug strikes while reading PIH interrupt status, force an immediate retry. Otherwise the twl4030 IRQ will never get re-enabled... Object size shrinks by 180 bytes, w00t! Signed-off-by: -

Get rid of another needless TWL header file: twl4030-pwrirq.h can easily live in twl4030.h; updating its three users. Also switch to the shared definition of the SIH_CTRL COR bit, remove useless-to-non-driver MODULE_ALIAS(), and add a note about a bug that will appear if anyone ever removes this code. No functional changes, just shrinkage. Signed-off-by:

Remove <linux/i2c/twl4030-rtc.h> by moving all the relevant contents into the driver itself, and removing the rest. Stuff removed included many useless bitmasks, and remnants of the platform data hook. Add markers inside the rtc driver to split sections apart: first data structure declarations, then the RTC driver, then platform bus glue for it all. There's still an issue with the twl4030-pwrirq.h registers ... this driver has no business touching them! This patch at least switches away from having private versions of those register definitions, and removes some unnecessary accesses to them. No functional changes, just shrinkage. Signed-off-by:

When a non-CORE DPLL is enabled via omap3_noncore_dpll_enable(), use the user's desired rate in clk->rate to determine whether to put the DPLL into bypass or lock mode, rather than reading the DPLL's current idle state from its hardware registers. This fixes a bug observed when leaving retention. Non-CORE DPLLs were not being relocked when downstream clocks re-enabled; rather, the DPLL entered bypass mode.

The <linux/i2c/...> directory has too many headers for twl4030 support. Start simplifying that by moving twl430-gpio.h into the main twl4030.h and also: - Providing comments to summarize the { module, offset } logical addressing vs the { i2c_client, register } physical addressing. - Moving the { module, offset } based I/O calls next to the place those modules are defined, with slightly improved descriptions. - Adding some section markers internal to twl4030.h so unrelated things can be visually separated. - Move TWL4030_GPIO_MAX adjacent to the other GPIO symbols. - Remove two more now-obsolete symbols (for GPIO pullup/pulldown). - Have global definitions of the three SIH_CTRL register bits, following the pattern of twl4030-core.c (and fixing a minor fault handling bug in reading the clear-on-read bit). To keep things simple, the only blocks with register declarations in this file should be ones with registers that (cleanly) get shared between components ... modules with SIH registers (for IRQ handling) being the obvious candidates. No functional changes. Signed-off-by: -

Clean up the twl4030-gpio code a bit ... mostly by shrinkage. Remove a bunch of macros that are just obfuscating what the TWL4030 GPIO code is doing. Some duplicated standard macros like BIT(); others hid trivial math (mask/shift); others were completely unused. Use BIT() in several places to highlight the bitmasking and make the code more compact. Remove pointless locking calls, sanity checks, and parenthesis. And needless irq_chip. Signed-off-by:
