This patch series adds support for UCI driver. UCI driver enables userspace
clients to communicate to external MHI devices like modem and WLAN. UCI driver
probe creates standard character device file nodes for userspace clients to
perform open, read, write, poll and release file operations. These file
operations call MHI core layer APIs to perform data transfer using MHI bus
to communicate with MHI device. Patch is tested using arm64 based platform.
Wait, I thought this was for modems.

Like it or not, but Jakub is absolutely right with his claim that
providing user-visible interfaces without any standardization is proven
as wrong.
Everybody agrees with standardizing things but the problem is, the
standardization will only happen when more than one person implements the
same functionality.
From my experience in RDMA and netdev, I can't agree with both of your
statements. There are a lot of people who see standardization as a bad
thing. Also we are pushing even one person to make user visible interfaces
right from the beginning without relation to how wide it will be adopted
later.
