[opensuse-arm] Drivers for display for rpi3
Hi Guys, I recently bought a display that depends on the following driver: https://kernel.googlesource.com/pub/scm/linux/kernel/git/gregkh/staging/+/ma... Could I get these drivers added to the kernel build for: http://download.opensuse.org/ports/aarch64/distribution/leap/42.2/appliances... Or point me in the right direction so I can make this contribution myself? I'm trying to get this into the upstream kernel also.

Looking at kernel.opensuse.org, kernel-source.git master branch has CONFIG_FB_TFT=m set in config/arm64/default, and so does stable branch. So before we discuss making changes to Leap releases, please verify that it works with a Kernel:stable (i.e., Tumbleweed) or even better Kernel:HEAD kernel-default. The latter is where new and experimental drivers get enabled. I need to know exactly which config options you need, as I do not have any MIPI DSI displays myself - there's several CONFIG_FB_TFT_* sub-options available. If it does work, the next question is, are all options available on openSUSE-42.2 branch. If so, you'll need to open a Bugzilla ticket. Ways to contribute yourself would be sending a patch to opensuse-kernel list or doing a pull request on GitHub (may need a ping on the list), but for stable branches a boo# is required. Whether kernel maintainers agree to enable new options for 42.2 now is out of our control; note that 42.3 is in the works. If the options are unavailable in 42.2/42.3, you could build a KMP.

You will probably need a devicetree overlay for the display as well. These are typically not autoconfigured. Thanks Michal -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

True. The Leap 42.2 version of u-boot-rpi3 did not enable support for "fdt apply", but the Tumbleweed version does, and in Base:System:Staging I have now enabled that feature for all boards and am waiting for anyone to complain. :) The Wiki links to overlay file examples in my GitHub repo for several expansion boards as inspiration. For our dtbs I have updated packaging branch, but it hasn't been merged into master yet, so I am testing a branch; without -@ full target-path needs to be used, and phandle references won't work beyond the local file, making pinctrl and gpio usage somewhat hard. -> upstream discussion and patches The older alternative of using individual "fdt" commands in U-Boot, that could be used in Leap 42.2, is still documented for some expansion boards, but may still have an endianness bug for phandles in Leap 42.2.
