The E850-96 board has a LAN9514 chip which acts as a USB hub and Ethernet controller. It's connected to the SoC via USB lines. In order to make this chip functional the USB controller in Exynos850 SoC has to be configured in the host role, and the corresponding power regulator has to be enabled as well.
This patch series enables USB host and network support on the E850-96 by making use of the LAN9514 chip. While at it, enable all power regulators (LDO) in the PMIC chip which can be useful in the bootloader and kernel, including the regulator used for LAN9514.
