Since we now have a proper Samsung PWM clocksource driver in place,
we can proceed with further cleanup of PWM timers support on Samsung SoCs.
This series attempts to achieve this goal by:
1) moving remaining Samsung platforms to the new clocksource driver
2) removing old clocksource driver
3) adding new multiplatform- and DT-aware PWM driver
4) moving all Samsung platforms to use the new PWM driver
5) removing old PWM driver
6) removing all PWM-related code that is not used anymore
Cleaning up the PWM driver is a bit tricky, because the design of current
driver makes it completely unsuitable for DT and multiplatform and would
require a heavy rework to make it usable, breaking any existing Samsung PWM
users by the way. To avoid any breakage I decided to keep the old driver,
add new one, move all platforms to it and then remove the old one.
See particular patches for more detailed descriptions.

I have tested this series on Mini2440 board (all v2 patches).
Only boot testing for now, however I'm going to inspect the PWM
output signal and will report back if there are any issues.

serial: samsung: enable clock before clearing pending interrupts
during init
Ensure that the uart controller clock is enabled prior to writing
to the
interrupt mask and pending registers in the s3c24xx_serial_init_port
function.

different story.
