Subject: Two thoughts about SPI chip-selects in the DTS
Date: Thu, 26 Feb 2009 13:13:34 +0100 [thread overview]
Message-ID: <ae4f76fd0902260413t2220d311v3dbd4e0254a27c66@mail.gmail.com> (raw)
As far as I understand the DTS bindings now support an SPI master controller to
- use the chip-selects controlled directly by the SPI master controller hardware
or
- to use GPIO's trough gpiolib as chip selects
but not a combination of both, am I right?
Now every SPI driver needs to be adapted to provide support for using
gpios as chip-selects, Wouldn't it be possible to let the
divers/of/of_spi take care of all the work required to use gpios as
chip-selects?
