I do not see the driver part.. No Nishant, this is not a part of driver series. This binding patch is related to [1] which is merged to net-next. The regmap will not be used by drivers/soc/ti driver instead once both binding are in, the driver changes will be needed in drivers/net/ethernet/ti/icssg/icssg_prueth.c as there is no driver changes needed in drivers/soc/ti, I posted this patch as stand alone. Considering this binding and [1] they both go to different tree, I decided to get the bindings in first and in next kernel cycle when they both are part of mainline linux, I can post the driver changes. > if this is a memory map, why doesn't bus model work? > I am just trying to maintain consistency here. pa-stats sub-module is similar to mii-g-rt and mii-rt. I am adding pa-stats in the same way as mii-g-rt and mii-rt. All these three modules are eventually mapping a memory region so that the icssg driver can use them and read / configure registers. > >> interrupt-controller@[a-f0-9]+$: >> description: | >> PRUSS INTC Node.
