| * OMAP4: PM: update ROM return address for OSWR and OFFCarlos Leija2011-10-171-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At wakeup from OFF/OSWR CPU1 will call secure HAL service through a local secure dispatcher with MMU off, thus ROM will save a PA return address. Later in the wakeup, when SMC driver calls and RPC through omap4_secure_dispatcher (MMU is on now), ROM code won't log the new return address as RPCs are handled different. Thus ROM will attempt to return to a PA address when the MMU is on and the system will hang. We need to do this for OSWR state and OFF state of mpu power domain, not just for device off(mpu pd OFF).

| * OMAP4: PM: restore iva/l3inst for GP devices as wellNishanth Menon2011-10-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | On OMAP4430 GP devices, we were not capable of hitting OFF mode due to various reasons, however for 4460, we are able to do the same on GP devices, so we should restore the IVA and l3instr regs on GP as well, so split it out.

| * OMAP4: SMC: Replace HAL service values with macros to improve readabilityBryan Buckley2011-10-174-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently when calling omap4_secure_dispatcher the HAL service IDs are just numbers and not very descriptive. This patch defines PPA_SERVICE_0 (0x21) which is a service in PPA that does nothing. Previously, 0x21 was being hardcoded in each case. It also plugs in FLAG_START_CRITICAL (0x4) macro where missing.

| * remoteproc: combine all the block notify head structures into oneFernando Guzman Lugo2011-10-172-73/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously there was 1 block notify head per each type of event that remoteproc could generate. That also causes that the users need one block notify per each event they register for. Now, everything is combined into one notify block head, with this change users will register a callback function which will receive all type of remoteproc events, so it is responsibility of the users to check for the events they really want.

| * tty: serial: omap: don't lock console in suspend.Colin Cross2011-10-172-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | serial_omap_suspend locks the console in suspend, even if it is not being used as the console, or another console is present. This causes console messages to be lost if the device hangs in suspend. The only reason to lock the console is to prevent new console writes from turning the serial port hardware back on, which would prevent the low power state in suspend. To allow the console to continue functioning without leaving the uart on in suspend, add a suspended flag to the port. If the uart is disabled while the suspend flag is set, use pm_runtime_put_sync_suspend instead of pm_runtime_put_autosuspend to force the uart to immediately go to a low power state. This will cause the uart to transition in and out of its low power state for every console write after it suspends, but will allow all console messages to immediately go to the serial console as well as other active consoles.

| * OMAP2+: DMA: Workaround for invalid source positionPeter Ujfalusi2011-10-171-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the DMA source position has been asked before the first actual data transfer has been done, the CSAC register does not contain valid information. We can identify this situation by checking the CDAC register: CDAC != 0 indicates that the DMA transfer on the channel has been started already. If CDAC == 0, we can not trust the CSAC value since it has not been updated, and can contain random number. Return the start address in case the DMA has not yet started. This is valid since in fact the DMA has not yet progressed. Note: The CDAC register has been initialized to 0 at dma_start time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ns_2_cycles uses the global variables T_num and T_den to convert nanoseconds to cycles, but T_num and T_den are not kept up to date on every memory bus frequency change. Instead, they are updated only when a memory frequency is used for the first time. If ns_2_cycles is called in setup_registers, which runs on every memory bus frequency change, it will use the memory bus frequency that was most recently used for the first time. Move the call to ns_2_cycles into emif_calculate_regs, which is only called the first time a memory bus frequency is used, and cache the result for use in setup_registers.

Therefore,the McPDM UL_DATA will be filling some garbage data to McPDM FIFO before codec ADC stabilization which creates pop noises. However, the debounce time is still required for ASR audio capture test to avoid oscillations. The conclusion, the codec start-up sequence is moved to twl6040 prepare to ensure that the codec ADC should be turn on before McPDM UL_DATA FIFO up for audio capture.
