Subject: [PATCH] x86/platform/geode: Convert LED to GPIO machine descriptor
Date: Mon, 27 Jul 2020 10:00:19 +0200 [thread overview]
Message-ID: <20200727080019.286172-1-linus.walleij@linaro.org> (raw)
This makes the machine look up the LED from a GPIO machine
descriptor table. The Geode LEDs should be on the CS5535
companion chip.
