Moving to kernel dev-4.13

Moving to kernel dev-4.13

[Joel Stanley]

Hello OpenBMCers,

I've pushed a new branch to the OpenBMC kernel repository. It's called
dev-4.13, and is based on the latest stable release from the 4.13
branch (4.13.5).

There are currently 40 patches on top of the upstream release that
include the patches sent upstream since 4.13 was released. In
addition, there is the new Aspeed clk driver that is out on the
upstream lists for review.

If you wish to have your non-upstreamed patches added to this tree,
please send them to the list with the [PATCH linux dev-4.13] tag.

If you have any questions or concerns then please use this thread to
kick off a discussion.

Cheers,

Joel

Have you looked at my reviews on v4 yet? They're not all acks :)

I haven't looked at the tree yet, but do we have a list of major
features that we expose in dev-4.10 to match against dev-4.13 to know
what needs to go in?

Maybe that's a lazy question and I should generate it myself...

Forgive me if I've forgotten, but did you send a patch to fix it? From
reading the issue it looks like you've got a clear understanding of the
bug and what might be done to fix it, and I think it would be best if
you sent a patch. However if you don't have one or don't feel you can
make one then Joel or I will look into it.

Cheers,

Andrew

Not yet. Thanks for the reviews, I'll get to that today

We should have a list. Here's a rough one:

$ git diff --dirstat=lines,1 v4.10.17..dev-4.10  | sort -hr
  20.1% arch/arm/boot/dts/
  13.2% drivers/fsi/
  10.6% drivers/pinctrl/aspeed/
   6.9% drivers/hwmon/pmbus/
   6.2% drivers/net/ethernet/faraday/
   6.0% drivers/hwmon/occ/
   5.0% drivers/i2c/busses/
   4.2% drivers/mtd/spi-nor/
   3.1% drivers/hwmon/
   3.1% drivers/
   3.0% Documentation/devicetree/bindings/
   2.5% drivers/gpio/
   1.9% include/
   1.7% drivers/misc/
   1.5% drivers/iio/pressure/
   1.5% drivers/clk/aspeed/
   1.3% arch/arm/mach-aspeed/
   1.1% drivers/leds/
   1.1% arch/arm/configs/
   1.0% net/ncsi/
   1.0% drivers/tty/serial/8250/
   1.0% drivers/mailbox/
   1.0% drivers/iio/adc/

A number of these were upstreamed between 4.10 and 4.13, so we do not
require any patches to be sent.

Cheers,

Joel
