[Bug 1134838] New: No Raspberry Pi official 7' touchscreen support with DRM/VC4
http://bugzilla.suse.com/show_bug.cgi?id=1134838 Bug ID: 1134838 Summary: No Raspberry Pi official 7' touchscreen support with DRM/VC4 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: nsaenzjulienne@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- So far we've been able to use the official 7' touchscreen using the frame buffer device provided by UEFI. This comes with the downside that VC4 has to be disabled in order for the setup to work. The alternative is to use VC4 and the raspberrypi-panel driver. This comes with some downsides: the setup depends on an overlay which isn't provided by anyone (Raspbian uses a custom firmware based frame buffer device) and the back-light is operated through the I2C0 bus, which is owned by the firmware. We should work towards getting the firmware based back-light implementation into the upstream kernel and with that discuss on integrating a suitable overlay into raspbian's kernel tree. -- You are receiving this mail because: You are on the CC list for the bug.
