Subject: [PATCH v2 0/2] drm: Add support for tiny LCD displays
Date: Fri, 27 Jan 2017 20:56:29 +0100 [thread overview]
Message-ID: <20170127195631.25265-1-noralf@tronnes.org> (raw)
This is an attempt at providing a DRM version of drivers/staging/fbtft.
The tinydrm library provides a very simplified view of DRM in particular
for tiny displays that has onboard video memory and is connected through
a slow bus like SPI/I2C.
Only core patches this time.
Noralf.
Changes since version 1:
- Add tinydrm.rst
- Set tdev->fbdev_cma=NULL on unregister (lastclose is called after that).
- Remove some DRM_DEBUG*()
- Write-combined memory has uncached reads, so speed up by copying/buffering
one pixel line before conversion.
