Re: [U-Boot] [PATCH v3 3/5] ARM: dm: mxs: gpio: Add support for DM/DTS in the mxs_gpio.c driver (DM_GPIO)

To have a consensus regarding the gpio-ranges and mxs_gpio - here is my proposition:

1. I can provide "gpio-ranges" properties to imx28-u-boot.dtsi

With support similar to one from drivers/gpio/gpio-rcar.c, which only extracts the info regarding pin mapping, but omits the phandle for pinmux (pinmux will not be supported).

2. I will not upstream those properties to Linux (and adjust the

working mxs gpio driver in any way) - they would be only U-Boot specific

Why not ?

3. The IMX_GPIO_NR() macro will not be defined for i.MX28 GPIO.

4. Considering point 3 - all converted boards will have to use dm_gpio*

API.

That's good.
