Pull ARM SoC fixes from Arnd Bergmann:
 "Too many fixes have accumulated in the soc tree, so this is a fairly
  large set. As usual, most of the fixes are for devicetree files, but
  there are also notable code changes for imx and omap regressions as
  well as some maintainer file updates.

  imx:
   - Fix an Ethernet issue on imx6ul-14x14-evk board that is caused by
     independent PHY reset.

   - Add missing `dma-coherent` property for LayerScape device trees to
     fix a kernel BUG report.

   - Use IRQCHIP_DECLARE for AVIC driver to fix a boot issue on i.MX25
     with fw_devlink=on.

   - Add missing I2C pinctrl entry for imx8mp-phyboard-pollux-rdk board
     to fix the broken I2C GPIO recovery support.

   - Add `fsl,use-minimum-ecc` property for imx6ull-myir-mys-6ulx-eval
     device tree to fix UBI filesystem mount failure.

  at91:
   - wrong phy address that blocks Ethernet use on boards with sama5d27
     SoM1

   - restrictive pin possibilities for sam9x60

  omap:
   - Fix ocp interconnect bus access error reporting for omap_l3_noc by
     setting IRQF_NO_THREAD

   - Fix changed mmc slot order regression by adding mmc aliases for
     am335x

   - Fix dra7 reboot regression caused by invalid pcie reset map

   - Fix smartreflex init regression caused by dropped legacy data

   - Fix ti-sysc driver warning on unbind if reset is not deasserted

   - Fix flakey reset deassert for dra7 iva

On NVIDIA Carmel cores, CNP behaves differently than it does on standard
ARM cores. On Carmel, if two cores have CNP enabled and share an L2 TLB
entry created by core0 for a specific ASID, a non-shareable TLBI from
core1 may still see the shared entry. On standard ARM cores, that TLBI
will invalidate the shared entry as well.

This causes issues with patchsets that attempt to do local TLBIs based
on cpumasks instead of broadcast TLBIs. Avoid these issues by disabling
CNP support for NVIDIA Carmel cores.
