[PATCH v4 0/4] gpio: vf610: allow disabling the vf610 driver

[PATCH v4 0/4] gpio: vf610: allow disabling the vf610 driver

[Martin Kaiser]

The vf610 gpio driver is enabled by default for all i.MX machines,
without any option to disable it in a board-specific config file.

Change gpio's Kconfig to allow disabling this driver. Disable it by
default unless we have a vf610 soc. Enable it in the defconfigs
for the i.MX chips that need it.

While at it, enable COMPILE_TEST for the vf610 gpio driver.

[PATCH v4 1/4] gpio: vf610: allow disabling the vf610 driver

[Martin Kaiser]

The vf610 gpio driver is enabled by default for all i.MX machines,
without any option to disable it in a board-specific config file.

Most i.MX chipsets have no hardware for this driver. Change the default
to enable GPIO_VF610 for SOC_VF610 and disable it otherwise.

Add a text description after the bool type, this makes the driver
selectable by make config etc.

any reason for having this default y for SOC_VF610, but not for the
other SOC that uses the same variant (i.MX7ULP, ... ?).

Ok, it's probably not as consistent as it could be.

It seems that there are three categories

* Vybrid SoCs

According to the reference manual, they all have the gpio-vf610 hardware.
Defaulting to y for SOC_VF610 makes sense. It's now possible to disable the
driver if a board doesn't need it.

There's a bunch of defconfigs, not sure which ones would have to enable
gpio-vf610 if it weren't on by default.

* imx7ulp

The devicetrees show that all imx7ulp have gpio-vf610 hardware. You're right,
we should use the same approach, i.e.
   default y if SOC_IMX7ULP
and get rid of the imx_v6_v7_defconfig change.

* imx8, imx9

For arm64, there are no SOC_... defines and there's only one defconfig. The
devicetrees don't show clearly which chip has gpio-vf610. We're on the safe
side if we enable gpio-vf610 in defconfig.

Does this make sense?

Sorry for the delay, other tasks got in the way.

The maintainers have meanwhile merged v4.

Basically, the conclusion of my last mail was that imx7ulp and soc_vf610 could
be configured in the same way to make things a bit clearer. This wouldn't be
much of an improvement compared to the v4 set, I'd suggest keeping the current
state.

Thanks,
Martin

[PATCH v4 3/4] ARM: imx_v6_v7_defconfig: enable the vf610 gpio driver

[Martin Kaiser]

The vf610 gpio driver is used in i.MX7ULP chips (Cortex A7, ARMv7-A
architecture). Enable it in imx_v6_v7_defconfig.

(vf610 gpio used to be enabled by default for all i.MX chips. This was
changed recently as most i.MX chips don't need this driver.)
