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!
