Merge tag 'tegra-for-4.21-firmware' of... 

Merge tag 'tegra-for-4.21-firmware' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/drivers

firmware: tegra: Changes for v4.21-rc1

These changes update the BPMP ABI header and implement a new variant of
the BPMP firmware version tag query if supported.

* tag 'tegra-for-4.21-firmware' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
  firmware: tegra: Use in-band messages for firmware version query
  soc/tegra: bpmp: Update ABI header
  firmware: tegra: Print version tag at full
  firmware: tegra: Switch to global mrq_is_supported()
  firmware: tegra: Add helper to check for supported MRQs
