[PATCH v5 00/10] ARM: dts: exynos: Prepare Spring

[PATCH v5 00/10] ARM: dts: exynos: Prepare Spring

[Andreas Färber]

Hello,

Based on the preinstalled 3.8 based ChromeOS kernel and previous 3.15 
based attempts by Stephan and me that broke for 3.16, I've prepared a 
device tree for the HP Chromebook 11 aka Google Spring.

v5 cleans up a regulator and the USB3503 hub and touches more 
exynos5250 files.

Not yet enabled are trackpad, Wifi and sound.

My rebasing branch for testing is here:
https://github.com/afaerber/linux/commits/spring-next

Regards,
Andreas

v1 -> v2:
* Dropped 3 documentation patches from series:
  2 picked up,
  https://patchwork.kernel.org/patch/4397271/
  https://patchwork.kernel.org/patch/4397291/
  1 already sent separately as v2, pending.
  https://patchwork.kernel.org/patch/4424881/
* Minimized and beautified Spring device tree and to some degree Snow as well.
  See individual patches.

v2 -> v3:
* Rebased: Two -cros-common cleanup patches were already applied
* Lots of small cleanups for both Snow and Spring
* Enabled I2S in Spring for symmetry
* Added lid-switch and gpio-keys pinctrls to Spring

v3 -> v4:
* Fixed pin-function 1 -> 0 for dp-hpd pinctrl, style cleanup

v4 -> v5:
* Dropped regulator and fixed USB3503 for Spring
* More cleanups, including SMDK5250 and Arndale

[PATCH v5 01/10] ARM: dts: Fix MMC pinctrl for exynos5250-snow

[Andreas Färber]

The pinctrl properties should be on the device directly and not on the
slot sub-node.

 v3: New (Doug Anderson)
 Redundant with Jaehoon Chung's general slot@0 deprecation,
 in case that hits the tree earlier.

Let's land this one before Jaehoon's, since it was a hidden
functionality change in his patch.  It will be an easy conflict to
resolve when his patch is applied.

Sounds good to me, I've applied this before Jaehoon's change.

Version 6 of this series has been already posted. However this
particular patch has not changed, so it's fine.

It is documented as such. :) Others did have changes, of course.

I've started looking into rebasing myself: beware that the smdk5250
cleanup has an additional conflict in the spi node (cs-gpios movement).

[PATCH v5 02/10] ARM: dts: Fold exynos5250-cros-common into exynos5250-snow

[Andreas Färber]

exynos5250-cros-common.dtsi was meant for sharing common pieces across
ChromeOS devices. This turned out premature, as several devices ended up
in the common file that are not common after all. Since the remaining
common ChromeOS pieces are fairly minor,  exynos5250-cros-common.dtsi
was requested to be merged into the Snow device tree, sharing only the
keyboard controller for now. This may be re-evaluated as both mature.

[PATCH v5 03/10] ARM: dts: Clean up exynos5250-snow

[Andreas Färber]

Use the new style of referencing inherited nodes and use symbolic names.
Reorder one pinctrl node in GPIO order.

Goal is the alignment of all exynos5250 based device trees for comparison.

Suggested-by: Doug Anderson <dianders@chromium.org>
Signed-off-by: Andreas Färber <afaerber@suse.de>
---
 v4 -> v5:
 * Introduced labels to consistently use new referencing style (Tomasz)
 * Use IRQ_TYPE_* constants
 * Use some more GPIO_ACTIVE_*

 v3 -> v4: Unchanged
 
 v3: New (Doug Anderson)

As much as possible it's nice to touch the main exynos dtsi file and
specific board files in different patches.  Among other things it
makes backporting the patch and resolving merge conflicts easier (if
someone doesn't care about snow they could just pick up the main dtsi,
for instance).

I'm not a total stickler and I'd love to see this land quickly to
avoid conflicts, though...

Itty bitty bitty nit that "bus" sorts alphabetically above "clk".  ;)
Maybe Kukjin would be willing to sort these when he applies?


Thank you for all your hard work on this one.  Things look MUCH MUCH
nicer!  I did a pretty thorough review of your changes and it all
looks good.

True. I guess I just reused the original order from within pinctrl.

I need to respin anyway for a .dtsi label, so I can factor this out
while at it.

Patches 1-2 could meanwhile already be applied by Kukjin.

As mentioned earlier, I don't think this is a particularly useful
change.  Just this boot argument is not enough to boot with anyway, so
listing it doesn't really help anyone.  In theory you could make some
assertion about what the "most popular" boot device and filesystem is,
but it seems unlikely to cover the majority of the cases.

I won't NAK this change myself, but I certainly won't push for it.

This patch should be entirely optional.

I believe you said it wasn't necessary because the bootloader supplies
it. My point is that someone needs to know what to put into the bootargs
(setenv / boot.scr / uEnv.txt) - knowing whether it's ttySAC3 vs.
ttySAC2 vs. ttyS0 etc. has been pretty handy for me. In this case, Snow
and Spring use an identical console, so not sure if it might be tty2 or
something elsewhere?

My question of what to use for linux,stdout-path (which was elsewhere
mentioned as successor to bootargs in that regard) remained unanswered.
Should it point to the dp-controller node or what?

...but in your case you're not including any of that info.  tty1 is a
LCD console, isn't it?

No idea since I've never heard of linux,stdout-path other than your
emails.  Maybe someone else can chime in and I'll learn something.  ;)

NAK.  dp_hpd is a generic SoC piece.  Pin function 0 and 1 are GPIOs.
Pin function 3 is special function.  This pin _is_ the hot plug detect
pin for display port.  When it's set as special function 3 it goes
straight into the hot plug logic of the display port controller.

Spring may have had its reasons to detect hot plug events on a GPIO
instead of using this pin, but that doesn't make this pin any less the
"hot plug pin".

Please advise how to handle it then: Should there be two different
pinctrl entries (if so, how should it be named?), or should spring
override the generic entry? As I reported, 3.8 has only one dp-hpd
pinctrl entry, so I dropped the dp-hpd-gpio naming.

IMHO this is the right way. Just name the GPIO variant dp_hpd_gpio.

Hi Andreas Färber,

I agree with Tomasz Figa and Doug Anderson.
Please refer to the following.

1. case: Standard HPD pin is used. (smdk5420)
arch/arm/boot/dts/exynos5420-pinctrl.dts
	pinctrl@13400000 {
		dp_hpd: dp_hpd {
			samsung,pins = "gpx0-7";
			samsung,pin-function = <3>;
			samsung,pin-pud = <0>;
			samsung,pin-drv = <0>;
		};
arch/arm/boot/dts/exynos5420-smdk5420.dts
	dp-controller@145B0000 {
		pinctrl-names = "default";
		pinctrl-0 = <&dp_hpd>;
		...

2. case: non-standard HPD pin such as GPIO is used. (peach pit)
arch/arm/boot/dts/exynos5420-peach-pit.dts
	pinctrl@13400000 {
		dp_hpd_gpio: dp_hpd_gpio {
			samsung,pins = "gpx2-6";
			samsung,pin-function = <0>;
			samsung,pin-pud = <3>;
			samsung,pin-drv = <0>;
		};
	dp-controller@145B0000 {
		pinctrl-names = "default";
		pinctrl-0 = <&dp_hpd_gpio>;
		...
		samsung,hpd-gpio = <&gpx2 6 0>;

So, you need to follow the second case.
"dp_hpd_gpio" can be used for Spring board.

Jingoo Han

I believe I already did so in v6 [0]? Please take a look there and let
me know if you still need anything changed. The label name seems
identical, whereas for the node name I adopted the dashes convention.

[PATCH v5 06/10] ARM: dts: Clean up exynos5250-smdk5250

[Andreas Färber]

Use the new style for referencing inherited nodes and use symbolic names.

Goal is the alignment of all exynos5250 based device trees for comparison.

Signed-off-by: Andreas Färber <afaerber@suse.de>

 v5: New
 Follow-up after adding dp_hpd pinctrl node new-style.

I notice that Ajay's iommu patch uses mfc here, so let's use it here,
too. Affects patches 7 and 10.

Since I NAKed that one, are you going to drop this patch?  It's
probably still a useful thing to do.

It sounds like you might be spinning?  ...if so I'll review it in the
next cycle...  Note: same feedback as before about splitting changes
to exynos5250.dtsi and actual board files...

[PATCH v5 07/10] ARM: dts: Clean up exynos5250-arndale

[Andreas Färber]

Use the new style of referencing inherited nodes, use symbolic names,
tidy indentation and reorder includes.

Goal is the alignment of all exynos5250 based device trees for comparison.

 v5: New
 Aligns with SMDK.

Re: [PATCH v5 07/10] ARM: dts: Clean up exynos5250-arndale

[Tomasz Figa]

Just wanted to report one issue unrelated to your changes I spotted
while reviewing this patch. See below.

This apparently makes little sense as I doubt anybody would be willing
to run a DP panel with refresh rate of 0,012 Hz...

Anyway, your patch just moves it, so this is just an unrelated report.

Best regards,
Tomasz

[PATCH v5 08/10] ARM: dts: Fix apparent GPIO typo in exynos5250-arndale

[Andreas Färber]

The GPIO flag 2 has no constant assigned, so this was probably active-low.

[PATCH v5 09/10] ARM: dts: Simplify USB3503 on exynos5250-arndale

[Andreas Färber]

There's no need for a simple-bus, place the smsc,usb3503a directly into
the root node. That's what we're going to do on exynos5250-spring.

Reported-by: Tomasz Figa <t.figa@samsung.com>

 v5: New
 Aligns with Spring's new USB3503 node.

 v4 -> v5:
 * Dropped bogus USB3 regulator (Vincent Palatin, Tomasz Figa)
 * Fixed USB3503 reset GPIO (Tomasz Figa)
 * Introduced labels to use new referencing style consistently (Tomasz Figa)
 * Don't override dp_hpd, moved to pinctrl_0 instead (Tomasz Figa)
 * mmc_1: Added comment from Snow's mmc_3 (Tomasz Figa / Doug Anderson)
 * Override /codec samsung,mfc-{l,r} properties for alignment with Arndale
 * Use more GPIO_ACTIVE_* constants
 * Use IRQ_TYPE_* constants
 * Dropped s5m_ prefix for s5m8767 LDO regulator labels (max77686 is gone)
 * Labeled also all s5m8767 BUCK regulators
 
 v3 -> v4:
 * Fixed samsung,pin-function 1 -> 0 for dp-hpd-gpio
 * Replaced dp-hpd-gpio with existing dp_hpd, overriding it
 
 v2 -> v3:
 * Use GPIO_ACTIVE_{LOW,HIGH} (Doug Anderson)
 * Use symbolic KEY_POWER instead of comment
 * Moved hsic_reset to new USB3503 node's reset-gpios (Vincent Palatin)
 * Use dp_hpd_gpio for dp-controller (Doug Anderson, Ajay Kumar)
 * Override sd1_{clk,cmd,cd,bus4} pinctrl similar to Snow (Doug Anderson)
 * Added ec_irq pinctrl for cros_ec (Doug Anderson)
 * Reordered nodes to minimize diff against Snow (Doug Anderson)
 * Dropped obsolete mmc_2 override (Doug Anderson)
 * Added lid-switch node (Doug Anderson)
 * Added gpio-keys pinctrl (Doug Anderson)
 * Added bootargs to avoid empty /chosen node and to document console setting
 * Renamed s5m8767_pmic node to avoid underscore
 * Use new style for overriding inherited pinctrl nodes, too
 * Enable i2s0 node
 
 v1 -> v2:
 * Use label-based overriding/extension of nodes. (Doug Anderson)
 * Dropped tps65090 for now, until we know where to place it.
 * Dropped non-Spring nodes from -cros-common.dtsi rather than disabling them.
 * Enabled a missing MMC node for access to internal storage.
 * Dropped display-timings from dp-controller node. (Ajay Kumar)

Note that these two are again untested! They are entirely optional.

I have looked through all the patches and they look good to me, so, for
the whole series:

Reviewed-by: Tomasz Figa <t.figa@samsung.com>

There is one unrelated issue I reported in my reply to patch 7/10, but
it is more of a bug report, not a comment to your patch.

Best regards,
Tomasz
