Subject: [PATCH v4 0/8] arm64: rockchip: Initial GeekBox enablement

Hello,

This series adds initial support for the RK3368 based GeekBox.

v4 does small cleanups and decouples us again from the stmmac discussions v3 kicked off.

stmmac patches have been proposed to fix GMAC issues in linux-next (and v4.5):

https://patchwork.ozlabs.org/patch/598331/
https://patchwork.ozlabs.org/patch/598332/

Regards,
Andreas

Subject: [PATCH v4 1/8] arm64: dts: rockchip: Clean up /memory nodes

A dtc update results in warnings for nodes with reg property but without
unit address in the node name, so rename /memory to /memory@0.

Subject: [PATCH v4 4/8] arm64: dts: rockchip: Add GeekBox config

The GeekBox contains an MXM3 module with a Rockchip RK3368 SoC.
Some connectors are available directly on the module.

This adds initial support, namely serial, USB, GMAC, eMMC, IR and TSADC.

Signed-off-by: Andreas Färber <[email protected]>

v3 -> v4:
* Renamed /memory node to resolve dtc warning

v2 -> v3:
* Squashed GMAC, eMMC, IR, TSADC (Heiko)
* Fixed IR pinctrl pull setting (Julien)
* Changed TSADC polarity (rebooted immediately due to fixed otp-out pin)

v1 -> v2:
* Dropped rk3368-geekbox.dtsi. rk3368-geekbox-landingship.dts can
#include "rk3368-geekbox.dts" just fine, when leaving out /dts-v1/;.
* Revisited always-on / boot-on for PMIC regulator nodes. (Heiko)
* Switched pmic-sleep from RK_FUNC_GPIO to RK_FUNC_2. (schematics)

Either you just made a mistake in my name or
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/Documentation/devicetree/bindings/submitting-patches.txt
needs an update. It clearly says:

"1) The Documentation/ portion of the patch should be a separate patch."

That's why I always do it this way.

looking at the dt-bindings git log, it seems that is handled in a variety of
ways :-) . Personally I'm doing completely new bindings separately but the
125th addition of a board just inside the dts patch.

But I guess we can also move it out again into a separate patch if you prefer
that :-) .

You're probably right about the commit message, but there is no voodoo
about i2c2 below.

Would you rather have i2c1 dropped for now? Having it disabled at least
documents that the connectors are there.

Separate would've been copy&paste! It's using the preprocessor
specifically to avoid having them be separate.

> I guess I'll just go to the talk about "Portable Device Tree Connector:

This is not a random expansion board to exchange, it's a baseboard and
as we found out one very specific to this module, so no reuse unlike
Shields. As mentioned elsewhere, I2C are not the only difference,
they're the only difference _for now_. USB-SATA bridge comes for free
via USB node; there's four GPIO buttons to be figured out, an I2S codec
somewhere, display options (that I cannot test myself) and additional
regulator(s) needed.

Do enjoy the talk and report your findings. The pure existence of
overlays for Beagleboard is not convincing to me for dropping this patch
though - we've had similar discussions among distro people before
settling for EFI boot. Reality is messy, unfortunately. For an FPGA I've
grudgingly agreed that given a sane U-Boot one can use dtb commands to
add a couple nodes via a boot.scr, sanitizing the matrix of hardware
models x FPGA bitstreams to just the hardware models; however this
Landingship board is actually sold in hardware and is the only sane
rk3368 devboard to date rather than just some bitstream file, and we at
openSUSE are looking to abandon boot.scr in favor of generic bootefi,
running counter to that idea. Here I'm still dealing with a vendor
U-Boot, so neither works for now, only supplying a feature-complete .dtb
in the resource image partition does, which I need to build from
something - this patch. So no is not a solution. And it's not like
you're swamped in rk3368 .dts files anyway.

Thanks for queuing the core bits,

Andreas

I've split out that documentation addition again and applied this separate

This dtc update in question hasn't landed in v4.6-rc1 and from what I
gathered will need some changes. The patch is obviously still correct, but I
have now moved it from v4.6-fixes to the regular v4.7 64bit dts changes.

also it seems "memory" is special and memory without unitname will stay
allowed [0], especially as uboot or other bootloaders may expect such a node
to insert the actual amount of memory into it.

Looking at uboot, fdt_fixup_memory_banks seems to look explicitly for a
"memory" node, so I'm actually not sure, if this is safe to keep at all.

so after pondering this some more, I decided to drop this change again.
/memory will stay allowed and might produce less issues with bootloaders
touching the memory values.
