[PATCH 0/7] arm64: dts: ls1028: GPU support and cleanups

[PATCH 0/7] arm64: dts: ls1028: GPU support and cleanups

[Michael Walle]

In an attempt to unify u-boot's and linux' device tree for the LS1028A SoC
we first need to clean up some network related stuff. Vladimir suggested to
move the Ethernet PHYs into the MDIO controller node, which is already the
case for u-boot's device tree. Further we unify the use of phy-mode and
phy-connection-type. Both have the same meaning, but phy-mode is used more
often in the kernel and for the ls1028a both were used. Replace
phy-connection-type with phy-mode.

Further move all the nodes which belongs to the CCSR into the /soc node.
These are the Mali display conntroller and its associated pixel clock PLL.
Finally, add the GPU node for the etnaviv driver under /soc.

[PATCH 1/7] arm64: dts: ls1028a: move pixel clock pll into /soc

Move it inside the /soc subnode because it is part of the CCSR space.

I just noticed that the dp0_out label has been changed to dpi0_out besides the move.  Is this an intentional change or a typo?  If intentional we probably should mention it, otherwise we should change it back as it is breaking build for off-tree patch that uses the label.

It's intentional, because dp0_out might sound like displayport. And
from what I've found the output is a display pixel interface, hence dpi.

I agree, that this should have been two patches, must have slipped.
But this series was merged months ago, so we can't change anything
anymore.

Besides, given the fact that there is no support for the DisplayPort
PHY in upstream (yet, I'm working on that), I doubt there are any
out-of-tree device trees, which don't use the proprietary NXP
driver.

Also, if there is an out-of-tree device tree, it should be easy
enough for NXP to change that :)

[PATCH 5/7] arm64: dts: ls1028a: disable usb controller by default

[Michael Walle]

One of the last devices which are enabled by default are the USB
controllers. Although the pins are not multi-function pins, some boards
might not use USB at all. Apply the "disabled-by-default" style also for
the USB controllers and enable the controllers in the actual device tree
of the boards.

[PATCH 6/7] arm64: dts: ls1028a: move PHY nodes to MDIO controller

[Michael Walle]

Move the PHY nodes from the network controller to the dedicated MDIO
controller. According to Vladimir Oltean direct MDIO access via the PF,
that is when the PHY is put under the "mdio" subnode, is defeatured and
in fact the latest reference manual isn't mentioning it anymore.

[PATCH 6/7] arm64: dts: ls1028a: move PHY nodes to MDIO controller

[Michael Walle]

Move the PHY nodes from the network controller to the dedicated MDIO
controller. According to Vladimir Oltean direct MDIO access via the PF,
that is when the PHY is put under the "mdio" subnode, is defeatured and
in fact the latest reference manual isn't mentioning it anymore.

[PATCH 7/7] arm64: dts: ls1028a: use phy-mode instead of phy-connection-type

[Michael Walle]

In linux both are identical, phy-mode is used more often, though. Also
for the ls1028a both phy-connection-type and phy-mode was used, one for
the enetc nodes and the other for the switch nodes. Unify them. But the
main reason for this is that the device tree files can be shared with
the u-boot ones; there the enetc driver only supports the "phy-mode"
property.

Actually that is not really a valid reason in itself for this change.
The enetc U-Boot driver is perhaps a bit silly in that it calls
ofnode_read_string(dev_ofnode(dev), "phy-mode") manually, especially
since right below, it uses dm_eth_phy_connect() which searches for both.

So we are artificially restricting what we support. It would be fine to
do the dm_eth_phy_connect first, then use phy->interface for enetc_start_pcs().

Anyway, I do not mind the patch at all.

You mean in u-boot. I had a patch for it, but because you suggested
to convert it to the new property name, it isn't really needed anyway.
u-boot is just using the device trees within its source tree, so I
didn't care anymore ;)

Applied all, except #4 which had been picked up separately.
