From 04e24b80a3ddf4cdf85e49a99d33aec27c9432ad Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 19 Jan 2016 12:28:31 +0100 Subject: mmc: tmio: add flag to reduce delay after changing clock status The docs for RCar Gen2 & 3 I have access to, mention delays of 5ms after stop and 1ms after start. Make it possible to apply these values.
