+Subject: [PATCH] pinctrl: bcm: bcm6362: fix warning
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The current implementation of bcm6362_set_gpio() produces the following
+warning on x86_64:
+drivers/pinctrl/bcm/pinctrl-bcm6362.c: In function 'bcm6362_set_gpio':
+drivers/pinctrl/bcm/pinctrl-bcm6362.c:503:8: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
+  503 |        (uint32_t) desc->drv_data, 0);
+      |        ^
+
+Modify the code to make it similar to bcm63268_set_gpio() in order to fix
+the warning.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+Add depends on OF so we don't get weird build errors on
+randconfig.
+
+Also order selects the same as the other drivers for
+pure aestetic reasons.
