Please don't combine dts and clk driver changes together. We generally
don't take dts changes through clk tree.

What tree is this based on?

This sort of depends shouldn't be necessary.

Allocations already print a big error message so this is useless.

OK, will separate clk driver in single submit next time.

Also 4.8-rc1, will base on clk-next to sent the patch.

Got it. Will fix like this:
+config COMMON_CLK_MT6797
+	bool "Clock driver for Mediatek MT6797"
+	select COMMON_CLK_MEDIATEK
+	default ARCH_MEDIATEK
+	---help---
+	  This driver supports Mediatek MT6797 basic clocks.
