[PATCH 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 step planned is
to add DT support.

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 your comments!
