33 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
34 same GPIO Controller IP hence this driver could be used for all.

54 It provides the framework where pins from the individual GPIO can be
55 individually muxed to GPIO function, through interaction with the
56 SoCs IOMUX controller. This features could be used only on SoCs which
57 support individual pin muxing.
