Subject: [PATCH v2] gpio: vf610: allow disabling the vf610 driver
Date: Tue, 16 Jan 2024 10:58:45 +0100 [thread overview]
Message-ID: <20240116095845.47458-1-martin@kaiser.cx> (raw)
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. Enable the driver in arm64's default
config and in imx_v6_v7_defconfig to support chips like i.MX7ULP,
i.MX8QM, DXL, ULP and i.MX93.
Fixes: 30a35c07d9e9 ("gpio: vf610: drop the SOC_VF610 dependency for GPIO_VF610")

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