Subject: [PATCH v6 08/14] dt-bindings: display: bridge: Add i.MX8qxp pixel link to DPI binding
Date: Wed, 17 Mar 2021 11:42:43 +0800 [thread overview]
Message-ID: <1615952569-4711-9-git-send-email-victor.liu@nxp.com> (raw)
In-Reply-To: <1615952569-4711-1-git-send-email-victor.liu@nxp.com>
This patch adds bindings for i.MX8qxp pixel link to DPI(PXL2DPI).
Reviewed-by: Rob Herring <robh@kernel.org>
Signed-off-by: Liu Ying <victor.liu@nxp.com>
---
v5->v6:
* Add Rob's R-b tag.
v4->v5:
* No change.
v3->v4:
* Add 'fsl,sc-resource' property. (Rob)
v2->v3:
* Drop 'fsl,syscon' property. (Rob)
* Mention the CSR module controls PXL2DPI.
v1->v2:
* Use graph schema. (Laurent)

+description: |
+ The Freescale i.MX8qxp Pixel Link to Display Pixel Interface(PXL2DPI)
+ interfaces the pixel link 36-bit data output and the DSI controller’s
+ MIPI-DPI 24-bit data input, and inputs of LVDS Display Bridge(LDB) module
+ used in LVDS mode, to remap the pixel color codings between those modules.
+ This module is purely combinatorial.
+
+ The i.MX8qxp PXL2DPI is controlled by Control and Status Registers(CSR) module.
+ The CSR module, as a system controller, contains the PXL2DPI's configuration
+ register.
