+Subject: [PATCH] pinctrl: sunxi: Disable strict mode for A64 pinctrl driver
+
+With kernel 4.15.y (and later):
+*  Strict mode was enabled by default via commit 1396007286b1e2fd5dd10ae6a5ccaaaed51ab762 which can/will cause breakage with existing implementations.
+* The ability to configure strict mode was added via commit aae842a3ff3385f27f1df8a9ee1494a416ec032d to allow older drivers to maintain existing behavior and avoid breakage.
+* Commit cd70387f892205bcd7b8093b0837269b0739cbe0 had then explicitly disabled strict mode for most other existing SoCs but did not include A64.
+
+This change is to update the A64 pinctrl driver similar to the other pre-existing SoC pinctrl drivers.
