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

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.
