[PATCH] vfio-pci: Virtualize PCIe & AF FLR

We use a BAR restore trick to try to detect when a user has performed a device reset, possibly through FLR or other backdoors, to put things back into a working state. This is important for backdoor resets, but we can actually just virtualize the "front door" resets provided via PCIe and AF FLR.

Re: [PATCH] arm: dts: fix rk3066a based boards vdd_log voltage initialization

happened to be left initted by the BIOS. Yes, that's already the case in the pwm-rockchip driver. Okay, I can try to implement what is described above, but, in the meantime, I think we should find a solution for Andy's initial problem. As I said, the problem you're describing (pins muxed to the PWM device when it should actually stay in gpio+input mode) is not new, and the old pwm-regulator and pwm-rockchip implementation (before my atomic PWM changes) were behaving the same way. What is new though, is the pwm_regulator_init_state() function [1], and it seems it's now preventing the probe of a pwm-regulator device if the initial PWM state is not described in the voltage-table. The question is, what should we do? 1/ Force users to put an entry matching this state (which means breaking DT compat) 2/ Put a valid value in drvdata->state even if it's not reflecting the real state 3/ Patch regulator core to support an "unknown-selector" return code. Mark, any opinion? Thanks, Boris [1]https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/drivers/regulator/pwm-regulator.c?id=refs/tags/next-20160922#n60
