Subject: [PATCH 2/3] RTF: drm/panel: simple: Add TI nspire panels
Date: Tue, 23 Jul 2019 15:37:54 +0200 [thread overview]
Message-ID: <20190723133755.22677-3-linus.walleij@linaro.org> (raw)
In-Reply-To: <20190723133755.22677-1-linus.walleij@linaro.org>
This adds support for the TI nspire panels to the simple panel
roster. This code is based on arch/arm/mach-nspire/clcd.c.
This includes likely the first grayscale panel supported.
These panels will be used with the PL11x DRM driver.
