Subject: [PATCH v4 5/6] ARM: dts: stm32: set framebuffer bit depth on stm32f746-disco
Date: Mon, 19 Jun 2023 18:55:24 +0200	[thread overview]
Message-ID: <20230619165525.1035243-6-dario.binacchi@amarulasolutions.com> (raw)
In-Reply-To: <20230619165525.1035243-1-dario.binacchi@amarulasolutions.com>

The board uses a limited amounts of RAM. The added property halves the
memory footprint required by the framebuffer.
