[U-Boot] [PATCH 0/2] syscon: update syscon_regmap_lookup_by_phandle

[Patrick Delaunay]

Change the function syscon_regmap_lookup_by_phandle()
introduced by commit 6c3af1f24e4b ("syscon: dm: Add a
new method to get a regmap from DTS") to have
Linux-compatible syscon API and add test for this case:
phandle to node with generic "syscon" compatible
not bound as syscon UCLASS by default.

Without the patch the added test failed.

And I also update sysreset-syscon driver to use
this function and simplify the code,
tested on my stm32mp1 board with:

	rcc_reboot: rcc-reboot at 50000000 {
		compatible = "syscon-reboot";
		regmap = <&rcc>;
		offset = <0x404>;
		mask = <0x1>;
	};

	rcc: rcc at 50000000 {
		compatible = "st,stm32mp1-rcc", "syscon";
		reg = <0x50000000 0x1000>;
		#clock-cells = <1>;
		#reset-cells = <1>;
	};

PS: compatible st,stm32mp1-rcc is bound to driver
    drivers/misc/stm32_rcc.c
