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.
