From 1e6ca1a6ad7285569b22465b8387db242b310553 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 4 Jul 2016 11:58:22 -0600 Subject: dm: core: Add an implementation of regmap_init_mem_platdata() Add an implementation of this function which mirrors the functions of the automatic device-tree implementation. This can be used with of-platdata to create regmaps.
