> Subject: [PATCH v8 0/3] Add RZ/G2L DSI driver
>
> This patch series aims to support the MIPI DSI encoder found in the
> RZ/G2L SoC. It currently supports DSI video 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
>
> This patch series is based on drm_misc and patches from drm/du/next
> [1]

> v7->v8:
> * Added Rb tag from Laurent.
> * Added hsfreq_max to struct rzg2l_mipi_dsi_timings.
> * Removed enums rzg2l_mipi_dsi_dphy_timings.
> * Replaced if else with for loop for finding dphy_timings
> based on hsfreq.
> * Removed checking "number of lanes capability" from rzg2l_mipi_dsi_
> startup() and added patch#3 for handling it in probe() and
> enforcing
> it in rzg2l_mipi_dsi_host_attach().
> * Added Labels with an "err_" prefix.
> out_pm_put->err_pm_put
> out_assert_rst_and_stop_clocks->err_stop
> out_stop_hs_clock->err_stop_clock
> out_pm_disable->err_pm_disable
> * Added error message for lane check in rzg2l_mipi_dsi_host_attach()
> * Replaced dev_warn->dev_err for the format error in
> rzg2l_mipi_dsi_host
> _attach(). Added missing "\n" and print the format for debugging.
> v6->v7:
> * Added rzg2l_mipi_dsi_stop() counterpart of
> rzg2l_mipi_dsi_startup().
> * Error labels are named according to the cleanup operation they
> perform.
> * Restored Max lane capability read after dphy timing initialization
> as per the guide lines from SoC design team.
> * Added recommended lut values for the Global Operation Timing
> parameters for MIPI DPHY.
> v5->v6:
> * Updated commit description
> * Moved handling of arst and prst from rzg2l_mipi_dsi_startup-
> >runtime
> PM suspend/resume handlers.
> * Max lane capability read at probe(), and enforced in
> rzg2l_mipi_dsi_host_attach()
> * Simplified vich1ppsetr setting.
> * Renamed hsclk_running_mode,hsclk_mode->is_clk_cont.
> * Fixed typo in probe error message(arst->rst).
> * Reordered DRM bridge initaization in probe()
> * Updated typo in e-mail address.
> v4->v5:
> * Added Ack from Sam.
> * Added a trivial change, replaced rzg2l_mipi_dsi_parse_dt()
> with drm_of_get_data_lanes_count_ep() in probe.
> v3->v4:
> * Updated error handling in rzg2l_mipi_dsi_startup() and
> rzg2l_mipi_dsi_atomic_enable().
> v2->v3:
> * Added Rb tag from Geert and Laurent
> * Fixed the typo "Receive" -> "transmit"
> * Added accepible values for data-lanes
> * Sorted Header file in the example
> * Added SoC specific compaible along with generic one.
> * pass rzg2l_mipi_dsi pointer to {Link,Phy} register rd/wr function
> instead
> of the memory pointer
> * Fixed the comment in rzg2l_mipi_dsi_startup()
> * Removed unnecessary dbg message from rzg2l_mipi_dsi_start_video()
> * DRM bridge parameter initialization moved to probe
> * Replaced dev_dbg->dev_err in rzg2l_mipi_dsi_parse_dt()
> * Inserted the missing blank lane after return in probe()
> * Added missing MODULE_DEVICE_TABLE
> * Added include linux/bits.h in header file
> * Fixed various macros in header file.
> * Reorder the make file for DSI, so that it is no more dependent
> on RZ/G2L DU patch series.
> v1->v2:
> * Added full path for dsi-controller.yaml
> * Modeled DSI + D-PHY as single block and updated reg property
> * Fixed typo D_PHY->D-PHY
> * Updated description
> * Added interrupts and interrupt-names and updated the example
> * Driver rework based on dt-binding changes (DSI + D-PHY) as single
> block
> * Replaced link_mmio and phy_mmio with mmio in struct rzg2l_mipi_dsi
> * Replaced rzg2l_mipi_phy_write with rzg2l_mipi_dsi_phy_write
> and rzg2l_mipi_dsi_link_write
> * Replaced rzg2l_mipi_phy_read->rzg2l_mipi_dsi_link_read
> 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.
