This patch fixes two problems in LM8323 PWM control. One is that locking is needed when setting and reading pwm->desired_brightness asynchronously. The other is that LM8323 may stop a PWM script only after the current instruction has finished. If it is a long RAMP, the chip would keep executing the old instruction and new settings were effectively ignored.

Various cleanups to the OMAP EHCI bus glue: - Whitespace fixes. - Busy-wait loops should really have timeouts, but lacking that ... at least cpu_relax() in the body. - Debug messages should end with newlines, so they don't break the next message; should not embed newlines; and should otherwise be clean and correctly spelled. - The probe() method should have initialized the SBRN value, so the driver didn't report "USB 0.0 started". - The MODULE_ALIAS() was missing its "platform:" prefix; doing it right means the module could hotplug/coldplug. No real functional change except for the hotplug/coldplug thing. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Tony Lindgren <tony@atomide.com>

Export Beagle's third LED to the LED framework, now that it's accessible through the twl4030-gpio code. Claim the VBUS control, defaulting to OFF. Boards that have an EHCI connector (not rev B) will need to update this slightly. (Ideally as part of adding hooks to the ehci-map code supporting external power switching and overcurrent detection.)

Expose the two TWL4030 LED signals as output-only GPIOs. Boards need to explicitly ask that this be done, to help avoid conflicts on boards using these same pins to hook up to a vibrator motor. Note that these are high drive open drain signals; LEDA is rated for up to 160 mA (!), LEDB up to 60 mA. Boards using one of these signals to drive a bank of LCD backlight LEDs would probably want to access the dedicated PWMs for brightness control, too; easy to add such support later. Example: Beagle has one real LED here (PWM not necessary), and one GPIO controlling VBUS output over EHCI (PWM not wanted).

Convert the hsmmc init code over to standard GPIO calls: gpio_request(), gpio_free(), gpio_get_value_cansleep(). NOTE that this doesn't pass GPIO numbers in to hsmmc_init(); those values are still hard-wired. (For the write protect signal, the LACK of value is hard-wired...)

Simplify handling of VBUS and ID status and the USB_PRES interrupt. This seems to resolve the problems I previously saw on Beagle and Overo boards. - Read the status directly, instead of trying to infer it from dodgey side effects of IRQ handling and trigger tweaking. - Stop trying to arrange those dodgey side effects; just leave the IRQ enabled at all times. - Check that status as part of driver probe, so the PHY can always be active by the time it's needed. (BUGFIX!) - Re-sequence probe() to be less racey, and to avoid duplicating logic found elsewhere (notably irq handling and PHY activation). - Make the irq_chip be the exclusive owner of PWR_EDR (finally). - Get rid of needless work_struct ... in this irq handling thread, it's safe and cheap to call sysfs_notify() directly. Stop enabling IRQs on the USB subchip. There's no IRQ handler for them, and since ALT_INT_REROUTE isn't being set they'll never arrive ... so there's no point to enabling them. Also add some comments about other things such an otg_transciever driver should be doing, fixing minor omissions; and remove some unnecessary file inclusions.

omap_i2c_unidle() and omap_i2c_idle() are called recursively during omap_i2c_probe(). This is evidently unexpected and will wipe out the I2C interrupt enable register the second time that omap_i2c_idle() is called consecutively. Any I2C transactions following a probe of a bus with at least one device on it will then time out. Fix by moving omap_i2c_idle() further up in omap_i2c_probe(). Ensure the I2C controller is marked as idle before the probe starts. Also attempt to catch future reappearances of this bug early in development by warning in omap_i2c_{un,}idle() when they are called recursively. Problem reported by David Brownell <david-b@pacbell.net>. Tested on 3430SDP and 2430SDP.

I can't test the pwrbutton stuff, but rtc and musb behave... With one issue: the usb transceiver glue misbehaves on startup if the device is connected. (Again.) I looked at this a bit, and I think the issue is probably caused by not actually using key USB registers ... IRQ trigger mode state transitions are at best a fragile proxy for the real state. (This is similar to the GPIO patch I just sent, but simpler except for the impact on the few drivers thinking oddly about IRQs. Those patches cover the key SIH modules, and a similar one affects the PIH in twl4030-core.) - Dave ================================ Streamline the "power irq" code, and some of the mechanisms it uses: - Support IRQ masking, not just unmasking; simpler code. - Use the standard handle_edge_irq() handler for these edge IRQs. - Use generic_handle_irq() instead of a manual expansion thereof. - Provide a missing spinlock for the shared data. In short, use more of the standard genirq code ... more correctly. Also, update the drivers using the "power IRQ" accordingly: - Don't request IRQF_DISABLED if the handler makes I2C calls; and defend against lockdep forcing it on us. - Let the irq_chip handle IRQ mask/unmask; it handles mutual exclusion between drivers, among other things. - (Unrelated) remove useless MODULE_ALIAS in pwrbutton. The USB transceiver driver still places some dodgey games with IRQ enable/disable, and IRQ trigger flags. At least some of them seem like they'd be simplified by using USB transceiver registers ... notably, startup code, which doesn't seem to check state before it enters an irq-driven mode. For the moment, these drivers still (wrongly) try to configure IRQ trigger modes themselves ... again, that's something that an irq_chip handles (but not yet, for this one). NOTE: tested (MUSB and RTC only) along with the init/retry hack to make twl4030-pwrirq work around the i2c-omap timeout problems.
