By default the position updates are read from dsp box when streambox size is not defined.if the streambox size is defined to some value then position updates can be read from the streambox.

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

By default clock source is selected as internal clock of 96Mhz which is not configurable. Now we select the clock source to external clock (ACLK) which can be configurable to different clock ranges depending on usecase.
