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 twl4030 GPIO support the new gpio_to_irq() hook Signed-off-by:
-
David Brownell authored
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:

Better TWL init on Beagle: use the setup() callback to learn IRQ assignments; and configure pullups/pulldowns. Signed-off-by:

David Brownell authored
Finish moving initialization of pullups and pulldowns for twl4030 GPIOs into board specific init. Remove partial/incorrect init code for that from the hsmmc glue. Doing this right requires some attention from board init logic, based on how the TWL chip is wired. Letting digital inputs float will waste power. Everyone with board schematics should update their board init code so it matches their boards; meanwhile, this returns to "current" behavior (all pullups disabled) but finally offers a way to do it "right". Note that the ULPI pins won't need this attention (muxed against gpio{3-5,9-12,14} pins), and neither will ones with external pullups or pulldowns (conventional for MMC/SD card detect).

twl4030_bci_battery.c is now moved to new style registration of twl4030 children. During the process a few bugfixes came, the main one is that twl4030-bci was releasing the wrong irq if battery registration had failed. Signed-off-by:

Improve handling of the OMAP-specific setup in twl4030-core, and remove various warnings on non-OMAP builds. The main remaining portability problem for this core code (from a build perspective) is needing symbols like TWL4030_PWR_IRQ_BASE which are undesirable and platform-specific. Signed-off-by:

Move the twl4030 GPIO support from drivers/i2c/chips to drivers/gpio, which is a more appropriate home for this code. The Kconfig symbol name is changed to match the GPIO_* convention for such symbols, so config files must change in the obvious ways (Kconfig will prompt you). There's now some helptext. It can now be compiled as a module, should anyone really want to do that; that'll be mostly useful for test builds. Sanity check the IRQ range we're given. Initialization order needed a bit of work too: core add_children() called only after IRQs get set up, gpio uses subsys_initcall. This depends on a patch making i2c driver model init use postcore_initcall. Signed-off-by:
