[PATCH v5 0/2] Cirrus Logic Family of ADCs

[PATCH v5 0/2] Cirrus Logic Family of ADCs

[Paul Handrigan]

his patchset provides ASoC support for the latest family
of Cirrus Logic multichannel, high performance audio ADCs.
The devices that are supported are CS5302 (2 channel ADC),
CS5304 (4 channel ADC), and CS5308 (8 channel ADC).

v5 changes:
- Add MODULE_LICENSE to cs530x-i2c.c

Paul Handrigan (2):
  ASoC: dt-bindings: cirrus,cs530x: Add initial DT binding
  ASoC: cs530x: Support for cs530x ADCs

What changed here? Changelog is limited to v5, but what happened in v4
that you invalidated my tag?

For exactly this case I wrote you a guide. Did you read it?

[1/2] ASoC: dt-bindings: cirrus,cs530x: Add initial DT binding
      commit: 0e2407ae89b340c385afdca1e1c61dd651ae6b35
[2/2] ASoC: cs530x: Support for cs530x ADCs
      commit: 2884c29152c098c32e0041061f8327bcdb4e0697

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
