[PATCH v2 0/5] drm: shmobile: Fixes and enhancements

[PATCH v2 0/5] drm: shmobile: Fixes and enhancements

[Geert Uytterhoeven]

	Hi all,

Currently, there are two drivers for the LCD controller on Renesas
SuperH-based and ARM-based SH-Mobile and R-Mobile SoCs:
  1. sh_mobile_lcdcfb, using the fbdev framework,
  2. shmob_drm, using the DRM framework.
However, only the former driver can be used, as all platform support
integrates the former.  None of these drivers support DT-based systems.

This patch series is a first step to enable the SH-Mobile DRM driver for
Renesas ARM-based SH-Mobile and R-Mobile SoCs.  The next step planned is
to add DT support.

Changes compared to v1:
  - Add Reviewed-by,
  - Drop dependency on ARM.

This has been tested on the R-Mobile A1-based Atmark Techno
Armadillo-800-EVA development board, using a temporary
platform-enablement patch[1].

Thanks for applying to drm-misc!

[PATCH v2 1/5] drm: shmobile: Use %p4cc to print fourcc codes

[Geert Uytterhoeven]

Replace the printing of hexadecimal fourcc format codes by
pretty-printed format names, using the "%p4cc" format specifier.

[PATCH v2 2/5] drm: shmobile: Add support for DRM_FORMAT_XRGB8888

[Geert Uytterhoeven]

DRM_FORMAT_XRGB8888 aka XR24 is the modus francus of DRM, and should be
supported by all drivers.

The handling for DRM_FORMAT_XRGB8888 is similar to DRM_FORMAT_ARGB8888,
just ignore the alpha channel.

[PATCH v2 3/5] drm: shmobile: Switch to drm_crtc_init_with_planes()

[Geert Uytterhoeven]

The SH-Mobile DRM driver uses the legacy drm_crtc_init(), which
advertizes only the formats in safe_modeset_formats[] (XR24 and AR24) as
being supported.

Switch to drm_crtc_init_with_planes(), and advertize all supported
(A)RGB modes, so we can use RGB565 as the default mode for the console.

[PATCH v2 4/5] drm: shmobile: Add missing call to drm_fbdev_generic_setup()

[Geert Uytterhoeven]

Set up generic fbdev emulation, to enable support for the Linux console.

Use 16 as the preferred depth, as that is a good compromise between
colorfulness and resource utilization, and the default of the fbdev
driver.

[PATCH v2 5/5] drm: shmobile: Make DRM_SHMOBILE visible on Renesas SoC platforms

[Geert Uytterhoeven]

The LCD Controller supported by the drm-shmob driver is present
on SuperH SH-Mobile SoCs, and on Renesas ARM SH/R-Mobile SoCs.
Unfortunately its config option is not visible on either, so the user
can never enable the support.

Fix this by dropping the dependency on ARM (for SuperH), and by widening
the dependency range to ARCH_RENESAS (for ARM).

  - Drop dependency on ARM, reword.

This driver was disabled on SuperH in commit c66de8cc2ea62941
("drm/shmobile: Add run-time dependencies") in v3.16 because of build
issues.  I couldn't find further details, but currently it builds fine
on (at least) arm, arm64, sh, riscv, and m68k.

Actually, as you're taking over maintenance for this driver, would you
