From 1e3fe0a434d0a08c4170b02c22c5c2251a2d2318 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Tue, 25 Mar 2014 15:51:50 +0100 Subject: [PATCH] spi: efm32: use $vendor,$device scheme for compatible string MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit 12f6dd860cf8bf036c0bec38c00a53da71bcd43a upstream. Wolfram Sang pointed out that "efm32,$device" is non-standard. So use the common scheme and prefix device with "efm32-". The old compatible string is left in place until arch/arm/boot/dts/efm32* is fixed.
