Are there any exynos*.txt bindings actually left after this series? If
no, maybe it's worth to remove this line while at it.

Yes, there are. These are the bindings which expect specific  external
fixed clock and I don't know yet how to model it in dtschema.

-* Samsung Exynos5250 Clock Controller
-
-The Exynos5250 clock controller generates and supplies clock to various
-controllers within the Exynos5250 SoC.
-
-Required Properties:
-
-- compatible: should be one of the following.
-  - "samsung,exynos5250-clock" - controller compatible with Exynos5250 SoC.
-
-- reg: physical base address of the controller and length of memory mapped
-  region.
-
-- #clock-cells: should be 1.
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos5250.h header and can be used in device
-tree sources.
-
-Example 1: An example of a clock controller node is listed below.
-
-	clock: clock-controller@10010000 {
-		compatible = "samsung,exynos5250-clock";
-		reg = <0x10010000 0x30000>;
-		#clock-cells = <1>;
-	};
-
-Example 2: UART controller node that consumes the clock generated by the clock
-	   controller. Refer to the standard clock bindings for information
-	   about 'clocks' and 'clock-names' property.
-
-	serial@13820000 {
-		compatible = "samsung,exynos4210-uart";
-		reg = <0x13820000 0x100>;
-		interrupts = <0 54 0>;
-		clocks = <&clock CLK_UART2>, <&clock CLK_SCLK_UART2>;
-		clock-names = "uart", "clk_uart_baud0";
-	};
