From 67cfac33a83176766cea5427a010d9e4d3f1b784 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20L=C3=BCtke-Stetzkamp?= Date: Sun, 29 Apr 2018 19:32:26 +0200 Subject: [PATCH] staging: mt7621-mmc: Remove transfer mode setting from proc MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently the transfer mode can be chosen between DMA, a size dependent mode and non-DMA by writing to a proc file. The upstream driver mtk-sd uses DMA all times. There is no apparent reason why somebody would like to change the transfer mode and the position of the setting in the debug part of the driver also indicates, that the option was used for debugging purposes. So it is removed to clean up the driver and bring it more in line with the upstream one.
