tty: serial/samsung: fix modular build There are a few bugs in the samsung serial driver when built as a loadable module, which makes the console code unavailable, as well as giving no access to the 'printascii' early debug function. This adds the appropriate compile time conditionals. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

serial: samsung: merge probe() function from all SoC specific extensions With reset port, set clock and get clock functions in SoC specific extentions being removed, only the driver probe is left over in these extensions. The probe function itself can be merged into one and moved into the samsung common serial driver. With driver probe also moved, all the SoC specific extentions are no longer required and they are deleted.

serial: samsung: remove all uses of get_clksrc and set_clksrc With clkdev based clock lookup support, the clock set and get operation using clock names communicated between the samsung uart driver and the SoC specific extension can be removed. In addition to that, for each platform specific extension, add the default clock selection, number of clock options for uart baud generator, clock selection bit mask and shift values which is required by the clkdev support in samsung uart driver. The default clock selection value 'def_clk_sel' specifies the default clock to be used as the source clock for baud rate generator in case the platform code does not specify the same.

serial: samsung: switch to clkdev based clock lookup 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.

serial: samsung: Add unified interrupt handler for s3c64xx and later SoC's 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.
