Subject: [PATCH 1/3] [v5 net-next] dt-bindings: net: add st,stlc4560/p54spi binding
Date: Thu, 7 May 2026 23:24:49 +0200 [thread overview]
Message-ID: <20260507212451.3333185-2-arnd@kernel.org> (raw)
In-Reply-To: <20260507212451.3333185-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb•de>
The SPI version of Prism54 was sold under a couple of different
names and supported by the Linux p54spi driver, but there was
never a DT binding for it.
Document the four known names of this device and the properties
that are sufficient for its use on the Nokia N8x0 tablet.
As I don't have this hardware or documentation for it, this is
purely based on existing usage in the driver.
