[U-Boot] [PATCH 0/9] Add common pinctrl driver support for rockchip
The common pinctrl driver for rockchip Socs, it depends the PINCTRL_FULL config. If use it, the default pinctrl setup from DTS could be configured at device probe.
David Wu (9): rockchip: rk3399-evb: defconfig: Disable SPL_OF_PLATDATA for new pinctrl driver ARM: rockchip: rk3188: Remove the pinctrl setup and enable uart at SPL ARM: rockchip: Kconfig: Remove the SPL_PINCTRL for rk3188 ARM: rockchip: Remove the pinctrl request at rk3288-board-spl rk3288: chrome: defconfig: Disable SPL_OF_PLATDATA for new pinctrl driver pinctrl: rockchip: Add common rockchip pinctrl driver rockchip: defconfig: Clean the unused pinctrl config pinctrl: rockchip: Clean the unused rockchip pinctrl drivers ARM: dts: rk322x: Correct the uart2 default pin configuration

You should reword this, as "fdedesc" ist not how the device-tree is usually referred to.

If the MMC always set up correctly for all configurations (e.g. bus-width) or should some of the setup be duplicated there to ensure that we catch all corner cases?

For this, I will do a check if we need to setup duplicated.

It seems that pinctrl is not requested for rk3188 SPL, remove it so that can save more space for SPL image size.

Please split this into multiple comments (and possibly multiple files) for the relevant per-SoC data structures. I'd like this to be multiple commits to add the individual data structures for each of the SOCs.
We had the fundamental discussion of how to deal with drivers that require additional config-structures and code for some SOCs in the HDMI/VOP context and we should follow the same here.

No point in always adding all possible SOC support in U-Boot. Given that users may be space-sensitive, we should only pull in support for those chips that are needed.
Furthermore, we've had the decision on how to structure such drivers earlier (last time I remember was for HDMI): there should be a common driver infrastructure and multiple mini-drivers that reference it (see drivers/video/rockchip/*_{vop,hmdi}.[ch]) and that can be selectively pulled in.
+U_BOOT_DRIVER(pinctrl_rockchip) = {
- .name = "rockchip_pinctrl",
- .id = UCLASS_PINCTRL,
- .of_match = rockchip_pinctrl_dt_match,
- .priv_auto_alloc_size = sizeof(struct rockchip_pinctrl_priv),
- .ops = &rockchip_pinctrl_ops,
+#if !CONFIG_IS_ENABLED(OF_PLATDATA)
- .bind = dm_scan_fdt_dev,
+#endif
- .probe = rockchip_pinctrl_probe,

Hi Philipp,
Okay, each SOC should have its own file, which include private data structure, and probe(). Can reduce driver size.

Use this driver to fit all Rockchip SOCs and to support the desired pinctrl configuration via DTS.
Please split this into multiple comments (and possibly multiple files) for the relevant per-SoC data structures. I'd like this to be multiple commits to add the individual data structures for each of the SOCs.
We had the fundamental discussion of how to deal with drivers that require additional config-structures and code for some SOCs in the HDMI/VOP context and we should follow the same here.

No point in always adding all possible SOC support in U-Boot. Given that users may be space-sensitive, we should only pull in support for those chips that are needed.
Furthermore, we've had the decision on how to structure such drivers earlier (last time I remember was for HDMI): there should be a common driver infrastructure and multiple mini-drivers that reference it (see drivers/video/rockchip/*_{vop,hmdi}.[ch]) and that can be selectively pulled in.
+U_BOOT_DRIVER(pinctrl_rockchip) = { + .name = "rockchip_pinctrl", + .id = UCLASS_PINCTRL, + .of_match = rockchip_pinctrl_dt_match, + .priv_auto_alloc_size = sizeof(struct rockchip_pinctrl_priv), + .ops = &rockchip_pinctrl_ops, +#if !CONFIG_IS_ENABLED(OF_PLATDATA) + .bind = dm_scan_fdt_dev, +#endif + .probe = rockchip_pinctrl_probe, +};
If we used the pinctrl-rockchip driver, these config is not needed, so remove them.
