This patch adds support for Himax HX8369A MIPI DSI panel.
Reviewed-by: Andrzej Hajda
Signed-off-by: Liu Ying
---
v6->v7:
* Address Andrzej Hajda's following comments.
* Simplify the return logic in hx8369a_dcs_write().
* Replace the macro hx8369a_dsi_init_helper() with a function array to improve
the code quality.
* Handle error cases during getting gpios in probe().
* Add 'Reviewed-by: Andrzej Hajda '.
v5->v6:
* Make the checkpatch.pl script be happier.
* Do not set the dsi channel number to be zero in probe(), because the MIPI DSI
bus driver would set it.
v4->v5:
* Address Andrzej Hajda's comments.
* Get the bs-gpios property instead of the bs[3:0]-gpios properties.
* Implement error propagation for panel register configurations.
* Other minor changes to improve the code quality.
v3->v4:
* Move the relevant dt-bindings to a separate patch to address Stefan
Wahren's comment.
v2->v3:
* Sort the included header files alphabetically.
v1->v2:
* Address almost all comments from Thierry Reding.
* Remove several DT properties as they can be implied by the compatible string.
* Add the HIMAX/himax prefixes to the driver's Kconfig name and driver name.
* Move the driver's Makefile entry place to sort the entries alphabetically.
* Reuse several standard DCS functions instead of inventing wheels.
* Move the panel resetting and power logics to the driver probe/remove stages.
This may simplify panel prepare/unprepare hooks. The power consumption should
not change a lot at DPMS since the panel enters sleep mode at that time.
* Add the module author.
* Other minor changes, such as coding style issues.
