Subject: [PATCH v3 1/3] gpio: vf610: allow disabling the vf610 driver
Date: Sat, 20 Jan 2024 19:29:27 +0100

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.

Fixes: 30a35c07d9e9 ("gpio: vf610: drop the SOC_VF610 dependency for GPIO_VF610")

v3:
 - split the changes into three patches

v2:
 - enable the vf610 gpio driver in the defconfig files for arm_v7
   (i.MX7ULP) and arm64 (i.MX8QM, DXL, ULP and i.MX93)
