From afefc4158f3c8529e4bb99c1dc119fd792bac220 Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Mon, 19 Jun 2006 19:53:19 +0100 Subject: [ARM] 3592/1: AT91RM9200 Serial driver update Patch from Andrew Victor This patch includes a number of updates to the AT91RM9200 serial driver. Changes include: 1. Conversion to a platform_driver. [Ivan Kokshaysky] 2. Replaced all references to AT91RM9200 with AT91. This driver can now also be used for the AT91SAM9216. 3. Allow TIOCM_LOOP to configure local loopback mode. 4. Cleaned up the 'read_status_mask' usage and interrupt handler code. [Chip Coldwell] 5. Suspend/resume support. [David Brownell] There are a few 'unused variable' warning when compiling this - I removed the new DMA support to keep this first patch simpler.
