It currently supports DSI mode only. This unit supports MIPI Alliance Specification for Display Serial Interface (DSI) Specification. This unit provides a solution for transmitting MIPI DSI compliant digital video and packets. Normative References are below. * MIPI Alliance Specification for Display Serial Interface Version 1.3.1 * MIPI Alliance Specification for D-PHY Version 2.1 The following are key features of this unit. * 1 channel * The number of Lane: 4-lane * Support up to Full HD (1920 × 1080), 60 fps (RGB888) * Maximum Bandwidth: 1.5 Gbps per lane * Support Output Data Format: RGB666 / RGB888 RFC->v1: * Added a ref to dsi-controller.yaml. * Added "depends on ARCH_RENESAS || COMPILE_TEST" on KCONFIG and dropped DRM as it is implied by DRM_BRIDGE * Used devm_reset_control_get_exclusive() for reset handle * Removed bool hsclkmode from struct rzg2l_mipi_dsi * Added error check for pm, using pm_runtime_resume_and_get() instead of pm_runtime_get_sync() * Added check for unsupported formats in rzg2l_mipi_dsi_host_attach() * Avoided read-modify-write stopping hsclock * Used devm_platform_ioremap_resource for resource allocation * Removed unnecessary assert call from probe and remove. * wrap the line after the PTR_ERR() in probe() * Updated reset failure messages in probe * Fixed the typo arstc->prstc * Made hex constants to lower case.
