[PATCH v2 1/6] ARM: tegra: nyan: Use proper IRQ type definitions

[PATCH v2 1/6] ARM: tegra: nyan: Use proper IRQ type definitions

[Paul Kocialkowski]

This switches a few interrupt definitions that were using
GPIO_ACTIVE_HIGH as IRQ type, which is invalid.

This is mostly a cosmetic change, that doesn't affect any driver.

[PATCH v2 2/6] ARM: tegra: nyan: Use external control for bq24735 charger

[Paul Kocialkowski]

Nyan boards come with an embedded controller that controls when to
enable and disable the charge. Thus, it should not be left up to the
kernel to handle that.

Using the ti,external-control property allows specifying this use-case.

[PATCH v2 3/6] ARM: tegra: nyan-big: Include compatible revisions for proper detection

[Paul Kocialkowski]

Depthcharge (the payload used with cros devices) will attempt to detect
boards using their revision. This includes all the known revisions for
the nyan-big board so that the dtb can be selected preferably.

Defining compatibly revisions allows depthcharge to select the kernel
via the revision it detects instead of using the default kernel. This
allows having a FIT image with multiple kernels for multiple devices.

[PATCH v2 5/6] ARM: tegra: nyan-big: Proper pinmux for TPM i2c

Is the ti,ac-detect-gpios property still useful in that case? I guess it
would still allow to monitor whether or not a charger is connected, even
if the EC determines that it shouldn't charge.

Anyway, I've applied this.

Yes, this is mostly what the bq24735 is used for in nyan devices: reporting
connection and disconnection events.

This line is the same as two lines above, so I've removed this one. I've
also used slightly different padding (two tabs and align to the first
string in the first line with spaces) to make it consistent with other
string lists in the file.

I've applied an s/i2c/I2C/ in the commit message and applied this. Can
you also make sure that these changes go into the nyan-big configuration
of the tegra-pinmux-scripts[0]? I know Stephen wants to keep those in
sync with the DTS.

Oops, sorry I missed that last faulty line. Actually, it should have contained:
"google,nyan-blaze-rev1", "google,nyan-blaze-rev0";

instead so that all revision, from 7 down to 0 are covered.

Should I make another patch on top to fix that?

This is missing a Signed-off-by: from Jerome and you (since you
forwarded the patch). I've added those since I assume that that was
intended and your both willing to provide it.

Other than that, same substitution for "i2c" -> "I2C" as on 5/6, and
please also make sure this change gets into the pinmux configurations.

Here's what I've put into Tegra's for-next, that has all the necessary
revisions, doesn't it?

	https://git.kernel.org/cgit/linux/kernel/git/tegra/linux.git/commit/?h=for-next&id=bfa3c0d4e8ba8eff525d34dbde0e76a98ebfbade

If so, no need for another patch.
