Merge tag 'mips_5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux

Pull MIPS updates from Paul Burton:
 "A light batch this time around but significant improvements for
  certain systems:

   - Removal of readq & writeq for MIPS32 kernels where they would
     simply BUG() anyway, allowing drivers or other code that #ifdefs on
     their presence to work properly.

   - Improvements for Ingenic JZ4740 systems, including support for the
     external memory controller & pinmuxing fixes for qi_lb60/NanoNote
     systems.

   - Improvements for Lantiq systems, in particular around SMP & IPIs.

   - DT updates for ralink/MediaTek MT7628a systems to probe & configure
     a bunch more devices.

   - Miscellaneous cleanups & build fixes"
