+Subject: [PATCH 1/3] ARM: dts: orange-pi-zero: specify XR819 WiFi chip
+ interrupts
+
+The orange-pi-zero board has Allwinner XR819 SDIO wifi chip. The board
+dts file provides a node enabling mmc1 controller. Together with an
+out-of-tree driver https://github.com/fifteenhex/xradio this node
+enables using the wifi chip.
+
+This commit specifies XR819 interrupt configuration for the driver.
