From: Andrew Victor Date: Mon, 19 Jun 2006 16:26:23 +0000 (+0100) Subject: [ARM] 3588/1: AT91RM9200 CSB337/637 board update X-Git-Tag: v2.6.18-rc1~1098^2~5^2~8 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=466e6227e6a54d9b94b50972612fe8bf0450f786;p=linux-2.6 [ARM] 3588/1: AT91RM9200 CSB337/637 board update Patch from Andrew Victor This patch updates the support for the Cogent CSB337 and CSB637 boards. The changes include: 1. Use the new at91_uart_config structure and device registration functions for the UARTs. 2. Registration of I2C and SPI platform devices. 3. The CSB337 board uses PB0 & PB1 (and not PB2) for the LEDs.
