Hi Greg, This series contain the final bits needed for the USB3 bus to work without staging drivers on Hikey 970. It takes a different approach from the past series: basically, it moves all IRQ related stuff into a new driver ( hi6421v600-irq), and the MFD driver (hi6421-spmi-pmic) is now quit simple: it contains just probe and regmap, which attaches into two MFD "child" drivers (a regulator driver and an IRQ one). This series also fixes a sutile bug recently introduced via the regulator tree (patch 2). Basically, the SPMI/MFD driver combination already uses the platform data, but the new patch re-uses it to store a mutex instead, overlapping the previous usage. This was unoticed on my past tests, as there were some unused data at the platform struct, that were big enough to store a mutex, but when I tried to remove it, it caused crashes and instability at the board.
