[PATCH] ARM: LPC32xx: Adjust dts files to gpio dt binding

Roland Stigge stigge at antcom.de
Sat May 19 06:28:53 EDT 2012


The GPIO devicetree binding in 3.5 doesn't register the various LPC32xx GPIO
banks via DT subnodes but always all at once, and changes the gpio referencing
to 3 cells (bank, gpio, flags). This patch adjusts the DTS files to this
binding that was just accepted to the gpio subsystem.
