Please submit patches using subject lines reflecting the style for the
subsystem.  This makes it easier for people to identify relevant
patches.  Look at what existing commits in the area you're changing are
doing and make sure your subject lines visually resemble what they're

Applied "spi: meson-axg: add SPICC driver support" to the spi tree

[Mark Brown]

The patch

   spi: meson-axg: add SPICC driver support

has been applied to the spi tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git 

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

Subject: [PATCH] spi: meson-axg: add SPICC driver support

Add new compatible string to support SPICC controller which
found at Amlogic Meson-AXG SoC. This is aiming at adding
a couple of enhanced feature patches.

Applied "spi: meson-axg: add SPICC driver support" to the spi tree

[Mark Brown]

The patch

   spi: meson-axg: add SPICC driver support

has been applied to the spi tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git 

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

This patch looks OK but it doesn't apply cleanly.

A quick glance suggests that it's becuase it has a dependency on the PWM
series, but that dependency was not described here (or in the cover
letter.)

If the series does not apply directly on mainline, the cover letter
should describe the dependencies clearly.

In your case, I understand it's difficult because you have many series
in parallel at the same time.  I would suggest that locally, you keep
each series as independent branches based on the latest -rc tag.  It's
pretty easy for me to resolve simple add-add conflicts when there are
two different series adding to the DT, but it can be more time consuming
when I have to figure out the dependencies myself, so I generally don't
do that and just reject the patches instead so the submitter can work
out (and document) the dependencies.

Also some questions...

Here you use the labels spicc_a and spicc_b, but the datasheet
uses 0 and 1.  Why the difference?

Hmm, but after looking at the pin definitions those are using A and B.
Confusing.

Can you clarify which is the right one, and also work with the datasheet
team on consistency?  Thanks!

This patch looks OK but it doesn't apply cleanly.

A quick glance suggests that it's becuase it has a dependency on the PWM
series, but that dependency was not described here (or in the cover
letter.)

If the series does not apply directly on mainline, the cover letter
should describe the dependencies clearly.

In your case, I understand it's difficult because you have many series
in parallel at the same time.  I would suggest that locally, you keep
each series as independent branches based on the latest -rc tag.  It's
pretty easy for me to resolve simple add-add conflicts when there are
two different series adding to the DT, but it can be more time consuming
when I have to figure out the dependencies myself, so I generally don't
do that and just reject the patches instead so the submitter can work
out (and document) the dependencies.

Also some questions...

Here you use the labels spicc_a and spicc_b, but the datasheet
uses 0 and 1.  Why the difference?

Hmm, but after looking at the pin definitions those are using A and B.
Confusing.

Can you clarify which is the right one, and also work with the datasheet
team on consistency?  Thanks!

Correction: while in general it's best to keep things based on the
latest -rc tag, for DT patches, it's even better if you base things on
my current <version>/dt64 branch (currently v4.16/dt64)
