* omap4: Move SOC specific code from board fileSantosh Shilimkar2010-05-207-54/+101
| | | | | | | | | | This patch moves OMAP4 soc specific code from 4430sdp board file. The change is necessary so that newer board support can be added with minimal changes. This will be also problematic for multi-board, multi-omap builds. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

* OMAP2/3/4: DMA: disable channel interrupts in omap_init_dma()Mika Westerberg2010-05-201-8/+19
| | | | | | | | | | | | | | | | | | | If we are softbooting another kernel using kexec, DMA controller state is not known when we are performing omap_init_dma(). It is possible that some DMA channels are already active. For example after kexec we get: <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 To prevent any weird things happening, we disable all channel interrupts during init.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can remove this wakeup dependency since now, when GPIO2-6 are enabled for IO-pad wakeup, PER domain is gauranteed to be awake or be woken up to service. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the wakeup capabilities of ads7846 touchscreen driver. ads7846 driver can now wakeup the system from suspend on OMAP3430 EVM and SDP boards. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP3530 TRM section 7.4.4.4.2 requires OFFOUTENABLE to be set (active low) if wakeup capabilities are enabled on a pad. 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.

| * | OMAP3: PRCM interrupt: only check and clear enabled PRCM IRQsKevin Hilman2010-05-121-5/+12
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | While handling PRCM IRQs, mask out interrupts that are not enabled in PRM_IRQENABLE_MPU. 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.

This patch renames the function to 'prepare_for_idle' and calls it for any powersate != PWRDM_POWER_ON passing in the powerstate. The hook itself is then responsible for doing various preparation based on the powerstate. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I believe the VMMC2 constraints must be the same than with VAUX3. 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.
