| Subject: ARM: shmobile: bockw: use wp-gpios instead of WP pin |
| |
| Latest Renesas Chip has some SDHI channels and the WP pin |
| availability depends on its channel or HW implementation. |
| Thus, this patch decides new policy whch indicates |
| WP is disabled as default. |
| But, we can use wp-gpios property to enable it as |
| other method. |
