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

[Biju]

From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>

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.

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.
