Certain tty line discipline implementations such slip and bluetooth hci invoke the serial core uart_write() api in their write_wakeup callback. This leads to a soft lockup with samsung serial driver since the uart port lock is taken in the driver's interrupt handler and uart_write() attempts to take the same lock again. Fix this issue by releasing the uart port lock before the call to uart_write_wakeup() in the tx handler. Also move the spin-lock/unlock sequence from s3c64xx_serial_handle_irq() function into the tx and rx irq handlers so that this change is applicable to s3c24xx platforms as well.

Instead of using clock names supplied in platform data, use a generic clock name 'clk_uart_baud' to look up clocks. The platform code should register clocks with the name 'clk_uart_baud' which can be used by the baud rate generator. The clock lookup and selection of the best clock as baud rate clock is reworked. Platform code can specify the clocks that can be used as source for the baud clock (as supported previously by passing names of clocks). A new member is added to the platform data 'clk_sel' which holds a bit-field value with each bit representing a baud source clock. If a bit at any bit position is set, that clock is looked up to participate in the selection of the baud clock source.

s3c2440 uses fclk/n (fclk divided by n) clock as one of the possible clocks used to generate the baud rate clock. The divider 'n' in this case can be logically represented outside of the uart controller. This patch creates a new clock by name "fclk_n" for s3c2440 based platforms to represent the fclk/n clock in the platform code. This clock provides a get_rate callback that checks the UCON0/1/2 registers to determine the clock rate. The samsung uart driver would receive the "fclk_n" clock name as one of the possible baud rate clock options and the driver need not determine clock rate of fclk/n.

s3c64xx and later SoC's include the interrupt mask and pending registers in the uart controller, unlike the s3c24xx SoC's which have these registers in the interrupt controller. When the mask and pending registers are part of the uart controller, a unified interrupt handler can handle the tx/rx interrupt. With this, the static reservation of interrupt numbers for the uart tx/rx/err interrupts in the linux irq space is not required and simplifies adding device tree support.
