Cover letter [PATCH 00/15] Final Samsung PWM support cleanup
Hi,

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 anymoreCleaning 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.
On S3C6410-based Tiny6410 (Mini6410-compatible), after enabling pwm-beeper:
Tested-by Tomasz Figa <[email protected]>Needs testing on other platforms as I could only compile test for them.
