Subject: atmel_spi: label GPIOs better
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=65f97a56944b797f5df714d677b541cca0829669;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

atmel_spi: label GPIOs better

Make the atmel_spi driver label GPIOs according to the device for which
they're acting as a chipselect.  This way the debugfs dump of gpio state is
more informative.
