Is the pinctrl repo the *exact* repo you used to test the patches on beaglebone? I tested on latest mainline after merging to am335x-upstream-staging-pinctrl (voltage also changing) Can you share your .config and uImage? My config details:- (After merge) 1. omap2plus_defconfig 2. Enable tps65217 MFD driver 3.

Add tps65217 regulator device tree data to AM335x-Bone by adding regulator consumers with tightened constraints and regulator-name. TPS65217 regulator handle can be obtained by using this regulator name. This patch also add I2C node with I2C frequency and tps65217 PMIC I2C slave address.
