Add generic PWM host commands for setting + getting duty cycle. PWMs can be controlled through index (board-specific meaning) or by type (currently KB backlight and display backlight are supported, more can be added as needed). BUG=chrome-os-partner:52002 BRANCH=None TEST=Manual on chell. `ectool pwmsetduty kb 100` - Verify KB backlight goes to 100% `ectool pwmgetduty kb` - Prints 100 `ectool pwmgetduty 0` - Prints 100 `ectool pwmsetduty 0 0` - Verify KB backlight goes to 0% `ectool pwmgetduty kb` - Prints 0 `ectool pwmgetduty disp` - Error res 3 (unsupported PWM type) `ectool pwmsetduty 1` - Error res 3 (non-existent PWM index) Signed-off-by: Shawn Nematbakhsh <shawnn@chromium.org> Change-Id: I607c92a291e6c2e3af8238eaf22ad2bb81ffc805 Reviewed-on: https://chromium-review.googlesource.com/344012 Commit-Ready: Shawn N <shawnn@chromium.org> Tested-by: Shawn N <shawnn@chromium.org> Reviewed-by: Randall Spangler <rspangler@chromium.org> Reviewed-by: Mary Ruthven <mruthven@chromium.org>
