2007-05-08ARM: OMAP: Sync core code with linux-omapTony Lindgren
This patch syncs omap specific core code with linux-omap. Most of the changes are needed to fix bitrot caused by driver updates in linux-omap tree. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-05-08ARM: OMAP: h4 must have blinky leds!!David Brownell
This adds generic support for the "debug board" LEDs used by most of TI's OMAP reference boards, and board-specific support for the H4. It's derived from the not-as-generic stuff used by OMAP1 H2/H3/P2. Those should be able to switch easily to this version, and clean up some of the omap1-specific code. In addition to H4 support, one key improvement is supporting not just the "old" ARM debug LED API (with timer and idle LEDs, plus four that can be handy for kernel debugging), but it also supports the "new" generic LED API (most useful for usermode stuff IMO). Either or both APIs can be enabled.

2007-05-05ARM: OMAP: MPUIO wake updatesDavid Brownell
GPIO and MPUIO wake updates: - Hook MPUIOs into the irq wakeup framework too. This uses a platform device to update irq enables during system sleep states, instead of a sys_device, since the latter is no longer needed for such things. - Also forward enable/disable irq wake requests to the relevant GPIO controller, so the top level IRQ dispatcher can (eventually) handle these wakeup events automatically if more than one GPIO pin needs to be a wakeup event source. - Minor tweak to the 24xx non-wakeup gpio stuff: no need to check such read-only data under the spinlock. This assumes (maybe wrongly?) that only 16xx can do GPIO wakeup; without a 15xx I can't test such stuff. Also this expects the top level IRQ dispatcher to properly handle requests to enable/disable irq wake, which is currently known to be wrong: omap1 saves the flags but ignores them, omap2 doesn't even save it. (Wakeup events are, wrongly, hardwired in the relevant mach-omapX/pm.c file ...) So MPUIO irqs won't yet trigger system wakeup.

2007-05-05ARM: OMAP: speed up gpio irq handlingDavid Brownell
Speedup and shrink GPIO irq handling code, by using a pointer that's available in the irq_chip structure instead of calling the get_gpio_bank() function. On OMAP1 this saves 44 words, most of which were in IRQ critical path methods. Hey, every few instructions help.

2006-09-25ARM: OMAP: GPIO: IRQSTATUS2 workaround for retention stateHiroshi DOYU
In OMAP2420, an incoming GPIO interrupt always sets both GPIO_IRQSTATUS1 and GPIO_IRQSTATUS2, even if the relevant bit is disabled in GPIO_IRQENABLE1/2 and DSP doesn't use GPIO at all. GPIO_IRQSTATUS1 is for MPU and GPIO_IRQSTATUS2 is for DSP. If IRQSTATUS is set, this will prevent the system from going to idle state. This patch also clears IRQSTATUS2 to avoid the above situation.
