[PATCH v2 11/12] OMAP: Serial: Use resume call from prcm to enable uart

2011-04-29 Thread Govindraj.R
Use resume idle call from prcm_irq to enable uart_port from low power states. Add api to check pad wakeup status which will we used from uart_resume func. to enable back uart port if a wakeup event occurred. UART_Resume func. can be removed once we have irq_chaining functionality available. Signe
