Hi All, As part of testing that my "ARM: dts: sun5i: Move display blocks to sun5i.dtsi" patch did not break anything I've been trying to get the sun4i-drm kms driver to work on a q8 a13 tablet.
I've build the drm / panel bits as modules after doing : [root@localhost ~]# insmod syscopyarea.ko [root@localhost ~]# insmod sysfillrect.ko [root@localhost ~]# insmod sysimgblt.ko [root@localhost ~]# insmod fb_sys_fops.ko [root@localhost ~]# insmod drm.ko [root@localhost ~]# insmod drm_kms_helper.ko [root@localhost ~]# insmod sun4i-tcon.ko [root@localhost ~]# insmod sun4i_backend.ko [root@localhost ~]# insmod panel-simple.ko [root@localhost ~]# insmod sun4i-drm.ko I get the following in dmesg: [ 87.791338] [drm] Initialized drm 1.1.0 20060810 [ 113.883947] panel supply power not found, using dummy regulator [ 119.199189] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
