commit ce35e21d82bcac8b3fd5128888f9e233f8444293 upstream.

Mediatek CMDQ driver have a mechanism to do TXDONE_BY_ACK,
so we should set knows_txdone.

NXP/FSL soc driver fixes for v5.6

DPAA2 DPIO
- Fix a kernel hang caused by irq requested before creating dpio

  soc: fsl: dpio: register dpio irq handlers after dpio create

The dpio irqs must be registered when you can actually
receive interrupts, ie when the dpios are created.
Kernel goes through NULL pointer dereference errors
followed by kernel panic [1] because the dpio irqs are
enabled before the dpio is created.

i.MX fixes for 5.6:

 - Build v7_cpu_resume() unconditionally to fix system hang in case that
   suspend is disabled but cpuidle support is enabled.
 - Drop unexisting Ethernet PHY device from imx8qxp-mek board.
 - Fix SRAM compatible strings on imx6dl-colibri-eval-v3 board.
 - Fix imx-scu driver to make sure that all messages words are written
   sequentially.
 - A series from Leonard Crestez to fix i.MX SC API users, having all
   messages aligned on 4 bytes.
 - Fix eMMC supply for phycore-som board.
 - Drop bogus frequency setting from imx7-colibri SD/MMC device, so that
   HS200 mode starts working and delivers better performance.
 - Fix opp-supported-hw for i.MX7D to get consumer and industrial parts
   work with correct frequency settings.
 - Restore MDIO compatible to the correct one for LS1021A SoC.

The imx SC api strongly assumes that messages are composed out of
4-bytes words but some of our message structs have odd sizeofs.

This produces many oopses with CONFIG_KASAN=y.

Fix by marking with __aligned(4).

If only Tegra194 support is enabled, the tegra30_fuse_read() and
tegra30_fuse_init() function are not declared and cause a build failure.
Add Tegra194 to the preprocessor guard to make sure these functions are
available for Tegra194-only builds as well.

 "Nothing too big or scary in here:

   - Support mremap() for the VDSO, primarily to allow CRIU to restore

   - Restore the MIPS32 cBPF JIT, after having reverted the enablement
     of the eBPF JIT for MIPS32 systems in the 5.5 cycle.

   - Improve cop0 counter synchronization behaviour whilst onlining CPUs
     by running with interrupts disabled.

   - Better match FPU behaviour when emulating multiply-accumulate
     instructions on pre-r6 systems that implement IEEE754-2008 style
     MACs.

   - Loongson64 kernels now build using the MIPS64r2 ISA, allowing them

   - Support for the Ingenic X1000 SoC & the really nice little CU Neo
     development board that's using it.
