Subject: [PATCH 11/13] ARM: dts: stm32: fix LTDC port node on STM32 MCU ad MPU
Date: Thu, 15 Apr 2021 12:10:35 +0200	[thread overview]
Message-ID: <20210415101037.1465-12-alexandre.torgue@foss.st.com> (raw)
In-Reply-To: <20210415101037.1465-1-alexandre.torgue@foss.st.com>

Running "make dtbs_check W=1", some warnings are reported concerning
LTDC port subnode:

/soc/display-controller@5a001000/port:
unnecessary #address-cells/#size-cells without "ranges" or child "reg"
property
/soc/display-controller@5a001000/port: graph node has single child node
'endpoint', #address-cells/#size-cells are not necessary

Signed-off-by: Alexandre Torgue <alexandre.torgue@foss.st.com>
