[PATCH v4 0/9] Add support for DU, LVDS and DSI on the Renesas RZ/G3L SoC

[PATCH v4 0/9] Add support for DU, LVDS and DSI on the Renesas RZ/G3L SoC

[Biju]

From: Biju Das <biju.das.jz@bp.renesas.com>

Hi All,

This patch series aims to add DSI, LVDS and LCD support for the RZ/G3L
SMARC EVK. The RZ/G3L LCDC is similar to the one found on RZ/G2L, but has
LVDS support.

The LVDS series [1] is merged here to get an overall picture.

[1] https://lore.kernel.org/all/20260625172359.292631-1-biju.das.jz@bp.renesas.com/

v3->v4:
 * Collected tag.
 * Dropped pwrrdy variable from struct rzg2l_mipi_dsi_hw_info and instead
   using feature flag RZ_MIPI_DSI_FEATURE_PWRRDY
 * Dropped rzg2l_mipi_dsi_pwrrdy_off() as it is taken care by
   devm_pwrseq_get().
 * Updated mode_clock_min from 5440->5400 kHz.
 * Added resets in pair for simplification.
 * Added comment in probe() for asserting resets.
 * Updated commit description for patch#8 and #9.
 * Updated license header  for patch#8 and #9.
 * Added HDMI audio support.
 * Dropped reg_1v8 and reg_3v3 nodes as they are redundant.
 * Renamed it6263 node name from it6263 to hdmi.
v2->v3:
 * Dropped binding patches as it is accepted.
v1->v2:
 * Dropped renesas,sysc-pwrrdy property as it is modelled as power
   sequence.
 * Switched to power sequence for handling pwrrdy signal.
 * Dropped header file regmap.h and mfd/syscon.h
 * Added header file pwrseq/consumer.h
 * Replaced syscon_field->pwrrdy in struct rzg3l_mipi_dsi_info.
 * Restored ports in DU bindings.
 * Replaced endpoint with port in ports node.
 * Dropped the macro RZG2L_DU_FEATURE_SMUX2_DSI_CLK and RZG2L_DU_MAX_LVDS.
 * Dropped the variable rcdu from struct rzg2l_du_encoder.
 * Dropped the variable lvds from struct rzg2l_du_device.
 * Dropped renesas,sysc-pwrrdy from dsi node.

[PATCH v4 8/9] arm64: dts: renesas: Add DSI overlay for RZ/G3L SMARC EVK with ADV7535

[Biju]

From: Biju Das <biju.das.jz@bp.renesas.com>

Add a Device Tree overlay (r9a08g046l48-smarc-dsi-adv7535.dtso) for the
RZ/G3L (R9A08G046) SMARC EVK board to support DSI-to-HDMI output via the
Analog Devices ADV7535 HDMI transmitter.

The overlay enables the DSI controller with a 4-lane data path, the
display unit (DU/LCDC), HDMI audio and configures the ADV7535 on I2C2.

Update the Makefile to build the overlay as both a standalone .dtbo and
a composite .dtb (base DTB + overlay).

[Severity: Low]
Will this composite DTB generation fail and halt the build process?

The fdtoverlay tool requires that target nodes exist in the base DTB. Because
the labels referenced in the overlay do not exist in the base DTB, it appears
this will break make dtbs for the architecture.

Does this target label actually exist?

This fragment targets the &dsi label, which appears to be missing from the

[Severity: Low]
Does this target label actually exist?

This fragment targets the &du (Display Unit) label, which also appears to

[Severity: Low]
Will this composite build target fail when fdtoverlay runs?

The base SoC device tree (r9a08g046l48-smarc.dtb) appears to lack any nodes
for the display controller or LVDS interface. When fdtoverlay attempts to
resolve the __fixups__ for the &du and &lvds nodes against the base DTB's
__symbols__, it will fail with an FDT_ERR_NOTFOUND error and break make dtbs.

[Severity: Low]
Are these includes necessary?

There don't appear to be any GPIO properties, interrupts, or pinctrl nodes
defined or referenced in this overlay file, so these directives could be
safely dropped.

[Severity: Low]
Does the &du label exist in the base r9a08g046l48-smarc.dtb?

If it's missing, fdtoverlay won't be able to resolve the symbol and will
fail.

[Severity: Low]
Does the &lvds label exist in the base r9a08g046l48-smarc.dtb?

Similar to the &du node, if this label is not present in the base tree,
fdtoverlay will fail during the build.
