Subject: [PATCH v2 0/6] pinctrl: st: Fix disparity between Pinctrl & GPIO in /sysfs
Date: Wed, 18 Mar 2015 17:21:13 +0000 [thread overview]
Message-ID: <1426699279-9258-1-git-send-email-lee.jones@linaro.org> (raw)
Version 2:
Fixed up Maxime's review comments
- Reduce size of char array
- Use snprintf()
Applied Maxime's Acks
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.

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
