In the interest of making long-term branch maintenance incur as little technical debt on us as possible, we should not maintain any files on the branch we are not actually using. This has the added effect of making it extremely clear when merging CLs from the main branch when changes have the possibility to affect us. The follow-on CL adds a convenience script to actually pull updates from the main branch and generate a CL for the update.

- *
- * Clearing bit 7 of ANX74XX_REG_ANALOG_CTRL_0 will cause the
- * ANX3429 to clear the cable_det signal that goes from the
- * ANX3429 to the EC. If this bit is cleared when a cable is
- * attached then cable_det will go high once standby is entered.
- *
- * In some cases, such as when the chipset power state is
- * S3/S5/G3 and a sink only adapter is connected to the port,
- * this behavior is undesirable. The constant toggling between
- * standby and normal mode means that effectively the ANX3429 is
- * not in standby mode only consumes ~1 mW less than just
- * remaining in normal mode. However when an E mark cable is
- * connected, clearing bit 7 is required so that while the E
- * mark cable configuration happens, the USB PD state machine
- * will continue to wake up until the USB PD attach event can be
- * regtistered.
- *
- * Therefore, the decision to clear bit 7 is based on the
- * current CC status of the port. If the CC status is open for
- * both CC lines OR if either CC line is showing Ra, then clear
- * bit 7. Not clearing bit 7 has no impact for normal cables and
- * prevents the constant toggle of standby<->normal when an
- * adapter is connected that isn't allowed to attach. Clearing
- * bit 7 when CC status reads Ra for either CC line allows the
- * USB PD state machine to be woken until the attach event can
- * happen. Note that in the case an E mark cable is connected
- * and can't attach (i.e. sink only port <- Emark cable -> sink
- * only adapter), then the ANX3429 will toggle indefinitely,
- * until either the cable is removed, or the port drp status
- * changes so the attach event can occur.
