Merge tag 'arc-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC updates from Vineet Gupta
- Jump Label support for ARC
- kmemleak enabled
- arc mm backend TLB Miss / flush optimizations
- nSIM platform switching to dwuart (vs. arcuart) and ensuing defconfig
updates and cleanups
- axs platform pll / video-mode updates
