+Subject: [PATCH] ARM: tegra: rm Jetson TK1 PMIC GPIO programming
+
+From: Stephen Warren <swarren@nvidia.com>
+
+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 96350f729c42 "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.
