The main MIPS changes for a pretty light v5.3 cycle, including:

Browse Source 
- 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.

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

     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
