I am trying to port U-Boot to a new product based on a Renesas RZ/G2M
(rcar-gen3). We're have this working with Renesas' version from
2018.09, but I am trying to integrate it with U-Boot 2020.07-rc4
What's happening is that it seems like all GPIO are failing to be
requested, so things like regulator-gpio fail, reset-gpios, etc. all
return errors.
The dm tree and gpio status commands all appear to show gpio banks are
enumerating, but since nothing can use the GPIO's it seems like the
common thread is the gpio driver for the rcar3.
I was hoping someone might have some thoughts of things I could try or
investigate. In order to properly set the voltage for the MMC card, I
need "regulator-gpio" to operate correctly.
The gpio regulator node looks like:
vccq_sdhi0: regulator-vccq-sdhi0 {
compatible = "regulator-gpio";
regulator-name = "SDHI0 VccQ";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <3300000>;
gpios = <&gpio6 30 GPIO_ACTIVE_HIGH>;
gpios-states = <1>;
states = <3300000 1>, <1800000 0>;
regulator-always-on;
};

Note that RZ/G2M is not supported by mainline U-Boot.
Also note that the GPIO driver and PFC drivers are working together,
grep for sh_pfc_config_mux_for_gpio(), so unless both work and probed,
the GPIO driver will likely not work.
Can you provide 'dm tree' output ?

I just sent a series [1] for review for porting the PFC, clock drivers
and MMC over.

It looks to me like the gpio driver looks for "rcar-gen3-gpio" which
is included in the SoC's DTSI file. I looked in Renesas' upstream
repo, but I didn't find anything unique in the gpio driver, but maybe
there is something in the gpio driver I missed.

I already submitted the board device tree stuff to the Linux community
and I am waiting for feedback to finalize it before attempting to post
here. If it's helpful, I can post the rest of my series with the
board device tree and board files instead of waiting.

Isn't the PFC driver missing here ?
