[PATCH 6.1.y-cip 1/8] drm: renesas: rz-du: Drop DU_MCR0_DPI_OE macro

[Biju Das]

commit e22c857aed59ed3f5f3e144039ef095521f15179 upstream.

The DPI_OE bit is removed from the latest RZ/G2UL and RZ/G2L hardware
manual. So, drop this macro.

[PATCH 6.1.y-cip 2/8] drm: renesas: rz-du: rzg2l_du_encoder: Fix max dot clock for DPI

[Biju Das]

commit 68573a561362cc11d4dbfdcf97127fbf0e118896 upstream.

As per the RZ/G2UL hardware manual Table 33.4 Clock List, the maximum
dot clock for the DPI interface is 83.5 MHz. Add mode_valid callback
to reject modes greater than 83.5 MHz.

[PATCH 6.1.y-cip 3/8] drm: renesas: rz-du: Add Kconfig dependency between RZG2L_DU and RZG2L_MIPI_DSI

[Biju Das]

commit 7e6cb7290b4a92a6af096b137b84bf285801a5d6 upstream.

Add Kconfig dependency between RZG2L_DU and RZG2L_MIPI_DSI, so that
DSI module has functional dependency on DU. It is similar way that
the R-Car MIPI DSI encoder is handled.

While at it drop ARCH_RENESAS dependency as DRM_RZG2L_DU depend on
ARCH_RZG2L.

[PATCH 6.1.y-cip 4/8] drm: renesas: rz-du: Support dmabuf import

[Biju Das]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

commit 66c302563985756f8154c4783b7a31e7137eb0fa upstream.

The rz-du driver uses GEM DMA helpers, but does not implement the
drm_driver .gem_prime_import_sg_table operation. This  prevents
importing dmabufs. Fix it by implementing the missing operation using
the DRM_GEM_DMA_DRIVER_OPS_WITH_DUMB_CREATE() helper macro.

[PATCH 6.1.y-cip 6/8] drm: renesas: Extend RZ/G2L supported KMS formats

[Biju Das]

From: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>

commit bc3faba1f96983f0aa9a6b2e800457e7e3b9a051 upstream.

The RZ/G2L driver utilises the VSPD to read data from input sources.

The rzg2l_du_kms component lists a restricted subset of the capabilities
of the VSPD which prevents additional formats from being used for
display planes.

The supported display plane formats are mapped in rzg2l_du_vsp_formats[].

Extend the rzg2l_du_format_infos[] table with the corresponding mappings
between the supported DRM formats and the formats exposed by the VSP in
rzg2l_du_vsp_formats, maintaining the same ordering in both tables.

The RPF module on VSPD supports various format conversion and send the
image data to BRS(Blend ROP Sub Unit) for further processing.

[PATCH 6.1.y-cip 7/8] drm: renesas: Add zpos, alpha and blend properties to RZ/G2L DU

commit e7bb7d44c3b97aea1f0e354c6499900154ac67f2 upstream.

Add support for zpos, alpha and blend properties to RZ/G2L DU
driver as the IP supports all these properties.

It is tested by the below modetest commands:

modetest -M rzg2l-du -s 44@42:1920x1080@AR24 -d -P \
37@42:512x300+200+200@XR15

modetest -M rzg2l-du -w {32,37}:alpha:{0,65535}
modetest -M rzg2l-du -w {32,37}:zpos:{0,1}
