From e8120ad129c160ff5b2e2b197d025a2cd661c2f2 Mon Sep 17 00:00:00 2001 From: Philip Rakity Date: Tue, 30 Nov 2010 00:55:23 -0500 Subject: [PATCH] mmc: sdhci: print SD Command and CAPABILITY_1 when dumping registers More information should be shown when sdhci_dumpregs is called. Knowing the command is useful for debugging, and Capability 1 is useful for SD v3.
