Subject: [PATCH v1 1/4] dt-bindings: input: Add Himax HX83102J touchscreen
Date: Fri, 22 Mar 2024 16:56:03 +0800 [thread overview]
Message-ID: <TY0PR06MB56116F0902017225C78EDDDD9E312@TY0PR06MB5611.apcprd06.prod.outlook.com> (raw)
In-Reply-To: <20240322085606.993896-1-allencl_lin@hotmail.com>
Add the HX83102j touchscreen device tree bindings documents.
HX83102j is a Himax TDDI touchscreen controller.
It's power sequence should be bound with a lcm driver, thus it
needs to be a panel follower. Others are the same as normal SPI
touchscreen controller.
