Subject: [PATCH v3] ARM: S3C24XX: Add WIZnet W5300E01-ARM board support
- The gpio routines are changed to use the gpio_request() functions from
comments of Vasily and Sylwester.
- The mistake of adding a character by my email client automatically is fixed.
Please review this patch and apply it if do not have any problems.
