From a9cd4a2f117f03abb4e4433b040c2225242fd35f Mon Sep 17 00:00:00 2001 From: Vadim Bendebury Date: Thu, 12 May 2016 16:40:37 +0800 Subject: rk3399: add GPIO register definitions for SDMMC0 The code needs to be able to set drive strength for the pins used for SDMMC0 interface. This patch adds the definitions for the two registers, as per page 378 of the RK3399 TRM Part 1. Instead of calculation of the reserved range size just use known offsets of the registers included in the structure. BRANCH=none BUG=chrome-os-partner:53257 TEST=with the upcoming driver change it is possible to boot chrome OS on Gru from various micro SD cards which were failing before.
