Subject: [PATCH v6 2/2] drm/panel: Add driver for Novatek NT36523
Add a driver for panels using the Novatek NT36523 display driver IC.
Signed-off-by: Jianhua Lu <lujianhua000@...il.com>
---
Changes in v6:
- Make the first mode to be DRM_MODE_TYPE_PREFERRED.
Changes in v5:
- use lowercase hex for init sequence
- fix code style
- enable DRM_MODE_TYPE_PREFERRED if where is only one mode.
Changes in v4:
- add multiple modes support
- use dev_err_probe helper
- fix dsi_info type string
- reimplement mipi_dsi_dual_dcs_write_seq() macro
Changes in v3:
- Refactor source code
Changes in v2:
- Refactor and clean up source code
