[PATCH] ASoC: SOF: OF: Add fw_path and tplg_path parameters

[PATCH] ASoC: SOF: OF: Add fw_path and tplg_path parameters

[Daniel Baluta]

From: Daniel Baluta <daniel.baluta@nxp.com>

This allows specifying an alternate path for SOF firmware or
SOF topology.

This is particularly useful for i.MX when running Linux vs Android.

[1/1] ASoC: SOF: OF: Add fw_path and tplg_path parameters
      commit: 7b84fd262d8a54ca609dd719c20c8a8e1a7ff759

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
