Legacy or non DT boot is no longer possible on systems where the
tw4030/5030 is used.

Drop the support for handling legacy pdata and replace it with a local
board_params struct to allow further cleanups on the mfd side.

Thanks!

[1/1] ASoC: twl4030: Drop legacy, non DT boot support
      commit: 7adadfb06b9839fa7d9de0cde7ad57a3be3665f0

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
