Subject: Re: [PATCH v14 4/6] pinctrl: add NXP MC33978/MC34978 pinctrl driver
Date: Fri, 22 May 2026 06:22:24 +0000 [thread overview]
Message-ID: <20260522062224.D2F001F000E9@smtp.kernel.org> (raw)
In-Reply-To: <20260522044855.1772639-5-o.rempel@pengutronix.de>

> Add pin control and GPIO driver for the NXP MC33978/MC34978 Multiple
> Switch Detection Interface (MSDI) devices.
>
> This driver exposes the 22 mechanical switch detection inputs (14
> Switch-to-Ground, 8 Programmable) as standard GPIOs.
>
> Key features implemented:
> - GPIO read/write: Translates physical switch states (open/closed)
> to logical GPIO levels based on the configured switch topology
> (Switch-to-Ground vs. Switch-to-Battery).
> - Emulated Output: Allows setting pins "high" or "low" by manipulating
> the tri-state registers and hardware pull topologies.
> - Interrupt routing: Proxies GPIO interrupt requests to the irq_domain
> managed by the parent MFD core driver via a hierarchical irq_chip.
