Subject: [PATCH v2 0/3] Add IMX8 SCU GPIO support
Date: Tue, 9 Aug 2022 09:31:02 -0500 [thread overview]
Message-ID: <20220809143105.17967-1-shenwei.wang@nxp.com> (raw)
The system controller (SCU) is the central unit to manage the resources
on i.MX8 platforms. The SCU firmware provides a set of APIs to access
the GPIO PINs on the SCU domain.
This patch series implements the standard GPIO driver over the SCU
firmware APIs, so that the GPIOs on the SCU domain could be accessed
like a local GPIO PINs.
Changes in V2:
- move the driver into the gpio directory per Krzysztof's feedback
- change the subnode description in file fsl,scu.yaml
- fix the dt_binding_check error
