The previous dependency did not handle all corner cases. Since there was no sleep dependency between CORE and PER domains, if PER enters RET and CORE is ON, PER will not be active for GPIO handling.

It is possible for the PER to enter RET while CORE is still in ON. If GPIO 2-6 are enabled for IO-pad wakeups, the PER domain will not wakeup in this case, unless we enable it.

The earlier approach of enabling wakeup on the touchscreen GPIO pin during board level mux init is removed. Instead the wakeup flag in ads7846_platform_data is enabled. Based on the flag, the ads7846 driver will do an enable_irq_wake which will eventually call into the OMAP GPIO layer and will enable the wakeup capability on the GPIO pin.

During OFF mode testing on OMAP3530 EVM, it was observed that the device was not residing in the OFF state. The device enters into the OFF state and immediately exits from that state as if an IO wakeup event has occured. The issue was traced down to the pad configuration of wkaeup enabled pad's.

If these are not masked out, non-enabled interrupts are caught, a WARN() is printed due to no 'handler' and the events are cleared. In addition to being noisy, this can also interfere with independent polling of this register by SR/VP code. This was noticed using SmartReflex transitions which cause the VPx_* interrupts to be handled since they are set in PRM_IRQSTATUS_MPU even but not enabled in PRM_IRQENABLE_MPU.

Older boards are using TWL4030 VMMC2 supply for internal MMC whereas newer are using VAUX3 that has more limited constraints defined in this same file. More over, the VMMC2 supply is used also for analog audio domain and the miminum analog voltage of the TLV320AIC34 codec is 2.7 V. To combine these two facts, the patch changes supply name to V28_A as the newer boards register VMMC2_30 for VAUX3 and uses the same constraints than VAUX3 since those constraints are ok for the TLV320AIC34.

The handler's purpose is to process interrupts generated by a GPIO line that a serial keyboard clock hangs off. It collects consecutive bits into words, pushing them into a buffer, then requests a higher level interrupt after one or more words are ready for further processing by a keyboard port driver. The handler also processes interrupts generated by two other GPIO lines, used by other on-board supported devices, by simply requesting a higher level interrupt, that in turn should invoke those device's specific irq handlers. IRQ12 line, not used by OMAP1510 hardware (described as reserved), has been choosen as a higher level interrupt source.

This will simplify the DEBUG_LL UART configuration for boards that may not have UART1, or have an external UART as it requires only one mapping for DEBUG_LL. The patch has a few limitations. Basically now we're assuming that the kernel uncompress code won't overlap with OMAP_UART_INFO. We also assume the printascii is called at least once before paging_init in order for addruart to have a chance to read the UART setup from OMAP_UART_INFO.
