* it83xx/KB/GPIO: support keyboard GPIO output modeRuibin Chang2020-10-141-3/+29
| | | | | | | | | | | | | | | | | | | | | | | These pins could be used as GPIO input, and they can be configured as GPIO output as well. So we made this patch to support it. BRANCH=none BUG=b:170699805 TEST=On board it8xxx2_evb 1.GPIO only: set/get level properly at GPIO mode. 2.GPIO and alternate mix: KSI input low and KSO GPIO level not change On board reef_it8320 1.keyboard scan function still work fine.

* it83xx/keyboard: enable push-pull for KSO2Dino Li2020-10-051-0/+3
| | | | | | | | | | | | | | | | | This change enables push-pull for EC's KSO2 if CONFIG_KEYBOARD_COL2_INVERTED is enabled (H1 inverts signal of column 2 to keyboard). BUG=b:169715234 BRANCH=octopus TEST= EC is able to drive KSO2 which connected to H1 to 3.3V.

| | | | | | | | | | | | | | | | | | | | | | 1. Always use wake-up control interrupt for keyboard KSI. This can also wake-up EC from deep doze / sleep mode. 2. In keyboard ISR, we just clear interrupt status to prevent keyboard interrupt can't be re-enabled. (for example, a KSI interrupt wakes up keyboard scan task, but keyboard_raw_read_rows() got 0.)
