Subject: [PATCH] ARM: dts: st: add buswidth property to stm32f429-disco
Date: Sun, 2 Jul 2023 12:35:16 +0200 [thread overview]
Message-ID: <20230702103516.139440-1-rgallaispou@gmail.com> (raw)
The ili9341 is left without a mandatory buswidth to properly communicate
between the SI bus and the display. Add the device-tree property.
