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.

Patch#4 has build dependency on [1]
[1] https://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux.git/commit/?id=d51fc9d4cd6eb18ac82913d83ecf7bd8c85f71ee

v2->v3:
* Dropped binding patches as it is accepted.
* Collected tags.
* Dropped .dsi_global_timings from rzv2h_mipi_dsi_info as it uses
different path.
* Updated powerseq API names.
* Moved set duty cycle from bridge driver to DU encoder.
* Added min/max frequencies for DPI.
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.
