| Description: | ||
| This entry allows enabling the sysoff mode of rt9467 charger | ||
| devices. | ||
| If enabled and the input is removed, the internal battery FET | ||
| is turned off to reduce the leakage from the BAT pin. See | ||
| device datasheet for details. It's commonly used when the | ||
| product enter shipping stage. After entering shipping mode, | ||
| only 'VBUS' or 'Power key" pressed can make it leave this mode. | ||
| 'Disable' also can help to leave it, but it's more like to | ||
| abort the action before the device really enter shipping mode. | ||

| Description: | ||
| This entry allows enabling the USB BC12 port detect function of rt9471 charger | ||

| port detect and report the usb port type when port detect is done. See | ||
| datasheet for details. Normally controlled when TypeC/USBPD port integrated. | ||

| description: | | ||
| RT9467 is a switch-mode single cell Li-Ion/Li-Polymer battery charger for | ||
| portable applications. It integrates a synchronous PWM controller, power | ||
| MOSFETs, input current sensing and regulation, high-accuracy voltage | ||
| regulation, and charge termination. The charge current is regulated through | ||
| integrated sensing resistors. | ||
| The RT9467 also features USB On-The-Go (OTG) support. It also integrates | ||
| D+/D- pin for USB host/charging port detection. | ||
