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.
Until you CC netdev on this (as suggested [1]), here's my:

UCI driver patch series includes following patches
1) bus: mhi: core: Add helper API to return number of free TREs
2) bus: mhi: core: Move MHI_MAX_MTU to external header file
3) docs: Add documentation for userspace client interface
4) bus: mhi: Add userspace client interface driver
mhi net driver can use #1 and #2 and these two are part of MHI core
driver change. These are helper API/macro which can be used by any mhi
clients like UCI or mhi net dev.
#3 and #4 are MHI UCI character driver completely unrelated to netdev.
How about splitting the patch series between #1,#2 and #3, #4 and add
netdev to #1, #2?
#1,#2 were already reviewed by two folks in community so it would be
much easier for netdev folks to refer that in context of mhi net device
driver.
Please let me know what do you think about this idea.
Thanks,
Hemant
