Subject: [PATCH v4 4/6] dt-bindings: display: stm32-ltdc: add optional st,fb-bpp property
Date: Mon, 19 Jun 2023 18:55:23 +0200 [thread overview]
Message-ID: <20230619165525.1035243-5-dario.binacchi@amarulasolutions.com> (raw)
In-Reply-To: <20230619165525.1035243-1-dario.binacchi@amarulasolutions.com>
Boards that use the STM32F{4,7} series have limited amounts of RAM. The
added property allows to size, within certain limits, the memory footprint
required by the framebuffer.
