Avoid unconditional context restore every time we gate uart clocks. Check whether context loss happened based on which we can context restore uart regs from uart_port structure.

Add missing uart regs to uart_port structure which can be used in context restore. Store dll, dlh, mdr1, scr, efr, lcr, mcr reg values into uart_port structure while configuring individual port in termios function.

Currently we use a shared irq handler to identify uart activity and then trigger a timer. By default the timeout value is zero and can be set or modified from sysfs. If there was no uart activity for the period set through sysfs, the timer will expire and call timer handler this will set a flag can_sleep using which decision to gate uart clocks can be taken. Since the clock gating mechanism is outside the uart driver, we currently use this mechanism. In preparation to runtime implementation for omap-serial driver we can cleanup this mechanism and use runtime API's to gate uart clocks. Removes the following: * timer related info from local uart_state struct * the code used to set timeout value from sysfs. * irqflags used to set shared irq handler. * un-used function omap_uart_check_wakeup.

The naming convention for omap_device is omap_XXX. Rename the device and driver name in order to stick to this naming convention. Remove the hs prefix that is implicit for every OMAP uarts.

Access to some registers depends on register access mode Three different modes are available for OMAP (at least) • Operational mode LCR_REG[7] = 0x0 • Configuration mode A LCR_REG[7] = 0x1 and LCR_REG[7:0]! = 0xBF • Configuration mode B LCR_REG[7] = 0x1 and LCR_REG[7:0] = 0xBF Define access modes and remove redefinitions and magic numbers in serial drivers (and later in bluetooth driver).

Only OMAP2+ platforms have the System Control Module (SCM) IP block. In the past, we've kept the SCM header file in plat-omap. This has led to abuse - device drivers including it; includes being added that create implicit dependencies on OMAP2+ builds; etc. In response, move the SCM headers into mach-omap2/. As part of this, remove the direct SCM access from the OMAP UDC driver. It was clearly broken. The UDC code needs an indepth review for use on OMAP2+ chips.

This patch adds driver support for OMAP2/3/4 high speed UART. The driver is made separate from 8250 driver as we cannot over load 8250 driver with omap platform specific configuration for features like DMA, it makes easier to implement features like DMA and hardware flow control and software flow control configuration with this driver as required for the omap-platform. This patch involves only the core driver and its dependent.
