[PATCH v2 0/3] Add Renesas SoC identification driver support

[Biju Das]

This patch series aims to support Renesas SoC identification driver.

Added a helper function of_match_node to find the matching of_match
structure. This helper function can be used to replace the following
code in u-boot [1] and [2]
[1] https://elixir.bootlin.com/u-boot/latest/source/drivers/serial/serial_uniphier.c#L129
[2] https://elixir.bootlin.com/u-boot/latest/source/drivers/usb/phy/rockchip_usb2_phy.c#L77

Also added soc_id attribute support in UCLASS_SOC which is required for Renesas SoC
identification driver similar to mainline linux.
