[PATCH v4 0/4] Add Renesas SoC identification driver support

[PATCH v4 0/4] 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.

v3->v4
  * Added Simon's Rb tag
  * Updated patch description for SoC identification using soc_id
  * Updated probe function of Renesas SoC identification driver.

[PATCH v4 3/4] dm: soc: Add SoC id for attribute matching

[Biju Das]

Mainline kernel uses the "soc_id" attribute to identify the SoC for some
of the h/w platforms. Adding this attribute in u-boot will make SoC
identification similar to the mainline kernel, so that it can be easily
maintained.

Add a new attribute named "soc_id" to SOC uclass, in order to allow device
drivers for identifying the SoC using SoC identification string and also
for matching this attribute for selecting SoC specific data.

[PATCH v4 0/4] Add Renesas SoC identification driver support

[Biju Das]

Hi All,

Just found that some of the patches in this series doesn't apply cleanly on mainline.
Will rebase and post new patch series.
