3 Samsung SoCs contain PWM timer blocks which can be used for system clock source
4 and clock event timers, as well as to drive SoC outputs with PWM signal. Each
5 PWM timer block provides 5 PWM channels (not all of them can drive physical
6 outputs - see SoC and board manual).
8 Be aware that the clocksource driver supports only uniprocessor systems.
11 - compatible : should be one of following:
12 samsung,s3c2410-pwm - for 16-bit timers present on S3C24xx SoCs
13 samsung,s3c6400-pwm - for 32-bit timers present on S3C64xx SoCs
14 samsung,s5p6440-pwm - for 32-bit timers present on S5P64x0 SoCs
15 samsung,s5pc100-pwm - for 32-bit timers present on S5PC100, S5PV210,
17 samsung,exynos4210-pwm - for 32-bit timers present on Exynos4210,
18 Exynos4x12 and Exynos5250 SoCs
19 - reg: base address and size of register area
20 - interrupts: list of timer interrupts (one interrupt per timer, starting at
22 - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
23 the cells format. The only third cell flag supported by this binding is
24 PWM_POLARITY_INVERTED.
27 - samsung,pwm-outputs: list of PWM channels used as PWM outputs on particular
28 platform - an array of up to 5 elements being indices of PWM channels
29 (from 0 to 4), the order does not matter.
