This patch lets sandbox-cros-ec emulate a limited pwm device which has multiple channels but can only set a duty cycle for each, as the actual EC doesn't expose any functionality or information other than that. Mapping non-generic EC_PWM_TYPE_* values to these emulated pwm channels is not implemented as nothing in U-Boot uses these types.
This commit messages is full of of abbreviations which makes it unclear. Please, use human readable terms.
I guess you might be talking about

But I am not sure.
Those are pretty much correct. I'm sending a v2 with hopefully a clearer commit message.

This emulated pwm is then used to test the cros-ec-pwm driver in sandbox. Adding the cros-ec-pwm node to the sandbox test device-tree unfortunately makes it the first pwm device, so this also touches some other tests to make sure they still use the sandbox pwm.
