ARM: SoC fixes for v5.10, part 3 

Another set of patches for devicetree files and Arm
 SoC specific drivers:
 
  - A fix for OP-TEE shared memory on non-SMP systems
 
  - multiple code fixes for the OMAP platform, including
    one regression for the CPSW network driver and a few
    runtime warning fixes
 
  - Some DT patches for the Rockchip RK3399 platform,
    in particular fixing the MMC device ordering that
    recently became nondeterministic with async probe.
 
  - Multiple DT fixes for the Tegra platform, including
    a regression fix for suspend/resume on TX2
 
  - A regression fix for a user-triggered fault in the
    NXP dpio driver
 
  - A regression fix for a bug caused by an earlier bug
    fix in the xilinx firmware driver
 
  - Two more DTC warning fixes
 
  - Sylvain Lemieux steps down as maintainer for the
    NXP LPC32xx platform
