Subject: [PATCH V2 52/69] SPEAr : Pad multiplexing handling modified
From: Vipin Kumar <vipin.kumar@...com>
Until now, the platform code assumed 1 32 bit register to be used for pad
multiplexing. This assumption is not true for SPEAr13xx devices, so the generic
implementation of pad multiplexing adopts a new concepts of multiple
multiplexing registers.
