[PATCH 0/6] pinctrl: st: Fix disparity between Pinctrl & GPIO in /sysfs

[Lee Jones <lee.jones@linaro.org>]

ST's hardware differentiates between GPIO mode and Pinctrl alternate
functions.  When a pin is in GPIO mode, there are dedicated registers
to set and obtain direction status.  However, If a pin's alternate
function is in use then the direction is set and status is derived
from a bunch of syscon registers.  The issue is; until now there was
a lack of parity between the two.

Further explanation with examples can be found in the commit logs.
