From: Leonard Göhrs Date: Wed, 14 Jun 2023 12:32:17 +0000 (+0200) Subject: dt-bindings: display: panel: mipi-dbi-spi: add spi-3wire property X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=222e0a8e2f8a89f41c518a43ced46e73c57a700e;p=linux.git dt-bindings: display: panel: mipi-dbi-spi: add spi-3wire property Some MIPI DBI panels support a three wire mode (clock, chip select, bidirectional data) that can be used to ask the panel if it is already set up by e.g. the bootloader and can thus skip the initialization. This enables a flicker-free boot.
