Subject: [PATCH v2 0/2] pwm: add PWM driver for atcpit100

The ATCPIT100 Programmable Interval Timer (PIT) is a set of compact
multi-function timers, which can be used as pulse width
modulators (PWM) as well as simple timers. ATCPIT100 supports up to 4
PIT channels, and each PIT channel may be a simple timer or PWM, or a
combination of the timer and the PWM.

This patch series includes DT-bindings(1/2) and PWM driver(2/2).

Changes in v2:
(1/2):
 - change "title" in the yaml file.
 - remove vendor-specific property, and add clocks property.
(2/2):
 - add a description for hardware limitations.
 - instead of statically configuring the clock source in the dtb,
   switch the clock parent depending on the requested setting.
 - have some minor changes according to Uwe's suggestion.
