Specifically, it enables control for the board pin headers and for the LEDs, as both of these features are only available behind a FPGA-based platform controller. This is structured around a MFD driver that provides a regmap interface to that platform controller to each MFD cell. The series is carved out from an out-of-tree support patchset, initially written for the original UP Board [2] and then extended through the past year to support new entries in the lineup (UP Board, UP Squared and UP Core) [3]. Here we only submit support for UP Squared to simplify review. Still, the driver is designed so that it can easily gain support for the other boards. V1 was originally submitted by Javier Arteaga in April 2018 as an RFC [4]. This V2 aims to address the feedback gratefully received from that.
