Difference between kernel branches in github.com/Freescale/linux-fslc repository

rspolyak — Mon, 04 Jan 2021 09:55:45 GMT

Repo https://github.com/Freescale/linux-fslc has branches that ends with -imx and branches that ends with -fslc. I suppose that -imx are official Freescale kernels whereas -fslc are supported by community. Are -imx branches merged to -fslc?

Currently I am using Yocto Dunfell with 5.4.x+fslc branch. However this branch does not include folder drivers/video/fbdev/mxc that contains video drivers that I need. On the other hand 5.4-2.1.x-imx does include this folder.

If I understood correctly, MXS video driver was removed in 5.3 kernel: https://patchwork.kernel.org/project/dri-devel/patch/20190520130612.2214-1-festevam@gmail.com/

Any examples how to port MXS based video driver to DRM version?

According to https://www.yoctoproject.org/pipermail/meta-freescale/2018-August/023214.html there is a branch `linux-fslc-imx` which include both community and iMX changes. However I do not see this branch neither at https://github.com/Freescale/linux-fslc/ nor at https://source.codeaurora.org/external/imx/linux-imx.

Is this information still up to date?

nxp does not support linux-fslc, please post this on meta-fsl-arm mailing list
