From 833462e94cf091ef11f34219ca92d093ff9d2c3c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Mon, 20 Aug 2012 09:57:04 +0200 Subject: serial/imx: improve error diagnosics for clock and pinctrl failures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit These error paths are used more often now after deep changes to the clock code and pinctrl is still new for imx. So help debugging and give clues in the boot log.
