+Subject: pinctrl: max77620: Use define directive for max77620_pinconf_param values
+
+From: Nathan Chancellor <natechancellor@gmail.com>
+
+commit 1f60652dd586d1b3eee7c4602892a97a62fa937a upstream.
+
+Clang warns when one enumerated type is implicitly converted to another:
+
+drivers/pinctrl/pinctrl-max77620.c:56:12: warning: implicit conversion
+from enumeration type 'enum max77620_pinconf_param' to different
+enumeration type 'enum pin_config_param' [-Wenum-conversion]
+ .param = MAX77620_ACTIVE_FPS_SOURCE,
+ ^~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is expected that pinctrl drivers can extend pin_config_param because
+of the gap between PIN_CONFIG_END and PIN_CONFIG_MAX so this conversion
+isn't an issue. Most drivers that take advantage of this define the
+PIN_CONFIG variables as constants, rather than enumerated values. Do the
+same thing here so that Clang no longer warns.
