Subject: GPIO polarity in bindings for Freescale MXS
Date: Thu, 14 Mar 2013 11:02:53 +0100 [thread overview]
Message-ID: <5141A04D.8020805@digi.com> (raw)
Hello,
Maybe I'm missing something but the MXS processors (at least i.MX23 and i.MX28) cannot
set the polarity of the GPIOs, so shouldn't the #gpio-cells be 1?
(From Documentation/devicetree/bindings/gpio/fsl-imx-gpio.txt):
- #gpio-cells : Should be two. The first cell is the pin number and
the second cell is used to specify the gpio polarity:
0 = active high
1 = active low
Regards,
