SUMMARY = "Linux Kernel provided by NXP and supported by Community"
DESCRIPTION = "Linux Kernel provided by NXP as the part of release distribution. \
Main focus is set on i.MX Family Reference Boards. \
It includes support for many NXP Proprietary IPs (GPU, VPU, IPU). \
Latest stable Kernel patchlevel is applied and maintained by Community."

###############################################################################
# This recipe (and corresponding kernel repository and branch) receives updates
# from 3 different sources:
# 1. Stable [linux-6.1.y] branch updates of korg;
# 2. NXP-specific updates via branch [lf-6.1.y] shared via GitHub NXP repo;
# 3. Critical patches, which are not (yet) integrated into either of 2 above
#    sources, but are required to be applied to the kernel tree.
#
# Therefore, there is a need to keep track on the patches which are introduced
# from every source. This could be achieved in this recipe by filling the
# below list with the information once the update is performed from any source.
#
# Once the critical patch gets merged into the stable branch, or NXP-specific
# patches would be covered by the tag - individual entries from sections below
# could be removed.
#
# ------------------------------------------------------------------------------
# 1. Stable (tag or SHA(s))
# ------------------------------------------------------------------------------
#    tag: v6.1.70
#
# ------------------------------------------------------------------------------
# 2. NXP-specific (tag or SHA(s))
# ------------------------------------------------------------------------------
#    tag: lf-6.1.55-2.2.0
#
# ------------------------------------------------------------------------------
# 3. Critical patches (SHA(s))

# NOTE to upgraders:
# This recipe should NOT collect individual patches, they should be applied to
# the linux-fslc kernel tree on the corresponding branch, and tracking
# information should be properly filled in above.
