f7f062919f arm64: dts: rockchip: fix rk3399-puma eMMC HS400 signal integrity
[ Upstream commit 62966cbdda ]

There are signal integrity issues running the eMMC at 200MHz on Puma
RK3399-Q7.

Similar to the work-around found for RK3399 Gru boards, lowering the
frequency to 100MHz made the eMMC much more stable, so let's lower the
frequency to 100MHz.

It might be possible to run at 150MHz as on RK3399 Gru boards but only
100MHz was extensively tested.

6dd5e12c0b arm64: dts: rockchip: rename and label gpio-led subnodes part 2
Current dts files with 'gpio-led' nodes were manually verified.
In order to automate this process leds-gpio.txt
has been converted to yaml. With this conversion a check
for pattern properties was added. In part 2 rename and label
gpio-led subnodes that passed the regex, but still don't have
the preferred form. Any pin subnode that ends with '-gpio'
in the pinctrl node generates a warning.

Fix with help of the following rules:

1: Add nodename in the preferred form.

2: Always add a label that ends with '_led' to prevent conflicts
   with other labels such as 'power' and 'mmc'

3: If leds need pinctrl add a label that ends with '_led_pin'
   also to prevent conflicts with other labels.

patternProperties:
  # The first form is preferred, but fall back to just 'led'
  # anywhere in the node name to at least catch some child nodes.
  "(^led-[0-9a-f]$|led)":

8a445086f8 arm64: dts: rockchip: fix rk3399-puma gmac reset gpio
The puma gmac node currently uses opposite active-values for the
gmac phy reset pin. The gpio-declaration uses active-high while the
separate snps,reset-active-low property marks the pin as active low.

While on the kernel side this works ok, other DT users may get
confused - as seen with uboot right now.

So bring this in line and make both properties match, similar to the
other Rockchip board.

bfb70fa503 arm64: dts: rockchip: fix vqmmc-supply property name for rk3399 puma
A test with the command below does not detect all errors
in combination with 'additionalProperties: false' and
allOf:
  - $ref: "synopsys-dw-mshc-common.yaml#"
allOf:
  - $ref: "mmc-controller.yaml#"

'additionalProperties' applies to all properties that are not
accounted-for by 'properties' or 'patternProperties' in
the immediate schema.

First when we combine rockchip-dw-mshc.yaml,
synopsys-dw-mshc-common.yaml and mmc-controller.yaml it gives
this error:

arch/arm64/boot/dts/rockchip/rk3399-puma-haikou.dt.yaml: mmc@fe320000:
'vqmmc' does not match any of the regexes:
'^.*@[0-9]+$', '^clk-phase-(legacy|sd-hs|mmc-(hs|hs[24]00|ddr52)|
uhs-(sdr(12|25|50|104)|ddr50))$', 'pinctrl-[0-9]+'

'vqmmc' is not a valid property name for mmc nodes.
Fix this error by renaming it to 'vqmmc-supply'.

c8e3993dd5 dt-bindings: hwmon (pwm-fan) Remove dead "cooling-*-state" properties
The old "cooling-{min,max}-state" properties for thermal bindings were
ratified to "cooling-{min,max}-level" by commit eb168b70de ("of:
thermal: Fix inconsitency between cooling-*-state and cooling-*-level"),
which were later removed entirely by commit e04907dbc2 ("dt-bindings:
thermal: Remove "cooling-{min|max}-level" properties").

The pwm-fan binding, however, was apparently in-flight in parallel with
that ratification, and so managed to introduce an example of the old
properties which escaped the scope of the later cleanup and has thus
continued to be dutifully copied for new boards despite being useless.
Clean up these remaining undocumented anachronisms to minimise any
further confusion.

d64420e816 arm64: dts: rockchip: bulk convert gpios to their constant counterparts
Rockchip SoCs use 2 different numbering schemes. Where the gpio-
controllers just count 0-31 for their 32 gpios, the underlying
iomux controller splits these into 4 separate entities A-D.

Device-schematics always use these iomux-values to identify pins,
so to make mapping schematics to devicetree easier Andy Yan introduced
named constants for the pins but so far we only used them on new
additions.

Using a sed-script created by Emil Renner Berthing bulk-convert
the remaining raw gpio numbers into their descriptive counterparts
and also gets rid of the unhelpful RK_FUNC_x -> x and RK_GPIOx -> x
mappings:

b4e1728232 arm64: dts: rockchip: Decrease emmc-phy's drive impedance on rk3399-puma
The RK3399-Q7 (Puma) requires 33 Ohm drive strength to ensure signal
integrity at HS-400 (200MHz clock, DDR signalling).

A repeated EMC testing run validates that this increase does not
negatively impact EMC compliance (emissions have ample distance to
the regulatory limits).

Commit c301b327ae ("arm64: dts: rockchip: add usb3-phy otg-port

the following message appears a few times:

The driver is deferred waiting for the typec-phy, but this never happens
beause is disabled. So, enable it.

The offending commit was reverted in 4.16-rc but can be re-applied
after enabling the typec phys.

87eba07160 arm64: dts: rockchip: remove vdd_log from rk3399-puma
vdd_log has no consumer and therefore will not be set to a specific
voltage. Still the PWM output pin gets configured and thence the vdd_log
output voltage will changed from it's default. Depending on the idle
state of the PWM this will slightly over or undervoltage the logic supply
of the RK3399 and cause instability with GbE (undervoltage) and PCIe
(overvoltage). Since the default value set by a voltage divider is the
correct supply voltage and we don't need to change it during runtime we
remove the rail from the devicetree completely so the PWM pin will not
be configured.
