[PATCH 0/3] Fix the PowerQUICC audio support using the QMC

[Herve Codina]

A previous series added the PowerQUICC audio support using the QMC.
The v6 version of this previous series was applied but some feedbacks
lead to a v7 version.

The v6 can be found here:
 https://lore.kernel.org/linux-kernel/20230217145645.1768659-1-herve.codina@bootlin.com/
and the v7, here:
 https://lore.kernel.org/linux-kernel/20230306161754.89146-1-herve.codina@bootlin.com/

This 'fix' series is the incremental version of v6 -> v7 and can only be
applied on the Marc Brown's tree as the v6 patches it fixes are only
present on this tree.

Regards,
Herve Codina

[PATCH 3/3] soc: fsl: cpm1: qmc: Fix assigned timeslot masks

[Herve Codina]

The assigned timeslot masks are 64bit values.
In case of 64 timeslots the code uses (1 << 64) which is undefined on a
64bit value. On the PowerPC architecture, this lead to an incorrect
result as (1 << 64) produces the same result as (1 << 0).

Fix the masks values taking care of the 64 timeslots case.

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
