7 title: Samsung SoC PWM timers
10 - Thierry Reding <thierry.reding@gmail.com>
11 - Krzysztof Kozlowski <krzk@kernel.org>
14 Samsung SoCs contain PWM timer blocks which can be used for system clock source
15 and clock event timers, as well as to drive SoC outputs with PWM signal. Each
16 PWM timer block provides 5 PWM channels (not all of them can drive physical
17 outputs - see SoC and board manual).

39 Should contain all following required clock names:
40 - "timers" - PWM base clock used to generate PWM signals,
41 and any subset of following optional clock names:
42 - "pwm-tclk0" - first external PWM clock source,
43 - "pwm-tclk1" - second external PWM clock source.
