From 4c9d53794bcfd3db45103269696b019d5ef09d41 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 3 Feb 2026 11:04:51 +0100 Subject: [PATCH] dt-bindings: spi: Add binding for Faraday FTSSP010 This adds a binding for the Faraday FTSSP010 SSP controller, a pretty straight-forward syncronous serial port and SPI controller. The bindings are submitted separately because the one device that has this is using it in a "nonstandard way" with regards to the electronics, and does not make it possible to develop or test a proper driver. However we want to be able to add this resource to the device trees and it's not complex.
