Uses patchset from hrdl rather than m-weigand. It was rebased against v6.15 by myself, from v6.15_rc3. hrdl rebased m-weigand's patchset from v6.12 and improved upon it. Much like linux-rpi, source code is generated by first using upstream linux source code, patched with minor release patchset. The PineNote downstream patches are then applied.
