The PON module supports various reset sources (physical pins) such as KPDPWR, RESIN, RESIN+KPDPWR. These pins can be configured for different reset types (such as warm, soft, hard) and can also be used as push buttons (keys). In the push-button configuration these pins act as gpios, only reporting the state on the line (high/low) and no additional pon based configuration being done in the hardware or software. They can be used for generic buttons (such as volume up/down, directional keys) Change-Id: Icde78b49b1037c1b5a13d7e90f772f72ac822b2a Signed-off-by: Anirudh Ghayal <aghayal@codeaurora.org>
