Subject: [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.

Karim BEN BELGACEM (1):
  ARM: STi: DT: STiH407: Fix retime pin mask for PIO5 and PIO35

Lee Jones (5):
  pinctrl: st: Introduce a 'get pin function' call
  pinctrl: st: Move st_get_pio_control() further up the source file
  pinctrl: st: Supply a GPIO get_direction() call-back
  pinctrl: st: Show correct pin direction -- even when in GPIO mode
  pinctrl: st: Display pin's function when printing pinctrl debug
    information
