Stephen Warren 7fb82986be ARM: tegra: rm Jetson TK1 PMIC GPIO programming ... The PMIC is configured such that its GPIOs have the correct configuration at power-up, so no programming is required. In fact, the current programming is actively wrong, since: (a) the AS3722 driver configures the GPIO to be an output before setting its output value, which causes a 0v glitch on the output. (b) the AS3722 driver configures the GPIO to drive a high voltage from its VSUP_GPIO power source rather than its VDD_GPIO_LV power source, so the pin drives 5V not 1.8V as desired. Solve these problems by removing the code which configures the PMIC GPIOs. Note that this patch was tested directly on top of v2016.01; since then, commit 96350f729c "dm: tegra: net: Convert tegra boards to driver model for Ethernet" prevents PCIe from being initialized. Alternatively, simply revert that commit to get PCIe Ethernet working again, then apply this patch to test.
