Add SD card write-protect pin configuration to be sure that it will be properly pulled down to indicate write access. Suggested-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Anand Moon <linux.amoon@gmail.com> --- Changes since v4: 1. Remove cd-gpios and wp-gpios leaving only WP pin configuration (after Marek Szyprowski feedback). 2. Pull pin down. 3. change the subject and commit message.
