Subject: [PATCH v3 0/5] drm: shmobile: Fixes and enhancements

	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 steps planned are
to (1) add DT support (works, but needs a hack due to lack of (2)), and (2)
convert the driver to atomic modesetting.

Changes compared to v2[1]:
  - Add Reviewed-by.

Changes compared to v1[2]:
  - 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[3].

Thanks for applying to drm-misc!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
