From 334eb9bcb94f6e02d96268b76dd270a399643176 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Tue, 4 Jun 2019 16:14:22 +0800 Subject: [PATCH] dt-bindings: mmc: sprd: Add another optional clock documentation For some Spreadtrum platforms like SC9860 platform, we should enable another gate clock '2x_enable' to make the SD host controller work well. Thus add documentation for this optional clock.
