[PATCH 0/3] ASoC: da7219: Reorganise device/codec level probe/remove

[Adam Thomson]

This patch set reorganises and fixes device and codec level probe/remove
handling within the driver, to allow clean probe and remove at the codec level.

This set relates to an issue raised by Yong Zhi where a codec level re-probe
would fail due to clks still being registered from the previous instantiation.
In addition some improvements around regulator handling and soft reset have
also been included.

  ASoC: da7219: Move required devm_* allocations to device level code
  ASoC: da7219: Move soft reset handling to codec level probe
  ASoC: da7219: Fix clock handling around codec level probe

[PATCH 1/3] ASoC: da7219: Move required devm_* allocations to device level code

[Adam Thomson]

In preparation for cleanup of device level and codec level probe
funcitonality, all necessary devm_* allocations and fw retrieval
functions are moved to the I2C probe level code.

[PATCH 2/3] ASoC: da7219: Move soft reset handling to codec level probe

[Adam Thomson]

As part of the reorganisation of the device level and codec
level probe functionlity, the soft reset handling should really
reside at the codec level and after the instantiation of supplies.
This commit makes the relevant changes to support this change of
scope including the remove of devm_* functions being called for
regulator instantiation at the codec level.

[PATCH 2/3] ASoC: da7219: Move soft reset handling to codec level probe

[Adam Thomson]

As part of the reorganisation of the device level and codec
level probe functionlity, the soft reset handling should really
reside at the codec level and after the instantiation of supplies.
This commit makes the relevant changes to support this change of
scope including the remove of devm_* functions being called for
regulator instantiation at the codec level.

[PATCH 3/3] ASoC: da7219: Fix clock handling around codec level probe

[Adam Thomson]

Previously the driver would use devm_* related functions at
the codec level probe() to allocate clock resources for MCLK
and the DAI clocks exposed by the device. This caused issues
when registering clocks on a re-probe (no device level
remove/prove involved) as the devm_* resources were never
freed up so the clocks were still registered from the previous
codec level probe().

This commit updates the clock handling for MCLK usage and DAI
clock provision to fix this discrepancy and allow the codec level
probe/remove functionality to operate as intended.

[PATCH 3/3] ASoC: da7219: Fix clock handling around codec level probe

[Adam Thomson]

Previously the driver would use devm_* related functions at
the codec level probe() to allocate clock resources for MCLK
and the DAI clocks exposed by the device. This caused issues
when registering clocks on a re-probe (no device level
remove/prove involved) as the devm_* resources were never
freed up so the clocks were still registered from the previous
codec level probe().

This commit updates the clock handling for MCLK usage and DAI
clock provision to fix this discrepancy and allow the codec level
probe/remove functionality to operate as intended.

Just to let you know that I tested this series on the JSL platform, the original issue was resolved, also sanity checked basic use case like plug/unplug and
suspend/resume, no regression found.

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
