7 title: device tree bindings for children of the Texas Instruments GPMC
14 This binding is meant for the child nodes of the GPMC node. The node
15 represents any device connected to the GPMC bus. It may be a Flash chip,
17 configuring the GPMC settings/timings and will accompany the bindings
23 # GPMC Timing properties for child nodes. All are optional and default to 0.
