Instead of using device tree, assuming you have firmware control,
another way could be to add a firmware feature:
for instance, there is one EC_FEATURE_PWM_FAN, the fan PWM, one for
the keyboard lightning as well. (see num ec_feature_code)
By adding one more, you let cros_ec_dev load the platform d
The ChromeOS Embedded Controller can support controlling its attached
PWMs via its host-command interface. The number of supported PWMs varies
on a per-board basis, so we define a "google,max-pwms" property to
handle this. And because the EC only allows specifying the duty cycle
and not the period,
