4 | Subject: [PATCH v2] am335x-evm: Fix bone pmic shut down over USB power | ||
5 | Cc: trini@ti.com, | ||
6 | chase.maupin@ti.com | ||
7 | |||
8 | * Set DCDC2 to 1.2v for all power sources and board revs except for A1 | ||
9 | * Set USB current trip point to 1300mA for all boards and power sources. | ||
10 | * Only Skip setting of MPU frequency to 720MHz for A1 and USB-powered boards. | ||
11 | |||
12 | Credits to Jason for noticing this. Tested with several reboots over USB on a Rev A2/3. | ||
13 | |||
14 | v2 changes: | ||
15 | Take care of not upping DCDC2 and LDO voltages for A1. | ||
16 | For A1- only operation done is to set the USB current limit. | ||
