In the past, there have been words on various lists that if LDO3 is
disabled in u-boot, but enabled in the DTS, the axp209 driver would
fail to continue/hang. Several enable/disable patches have been
issues to devicetree's in both the kernel and u-boot to address
this issue.
What really happened however, was that the AXP209 shuts down without
a notice and without setting an interrupt. This is caused when LDO3
gets overloaded, for example with large capacitors on the LDO3 output.
Normally, we would expect that AXP209 would source 200 mA as per
datasheet and set and trigger an interrupt when being overloaded.
For some reason however, this does not happen.
As a work-around, implement software-based 'regulator-soft-start'
property for AXP209 LDO3 regulator, which is used to first bring up
the LDO3 to the lowest possible voltage and then enable the LDO.
After that, we can set the requested voltage as usual.
Combining this setting with the regulator-ramp-delay allows LDO3 to
come up slowly and staggered, potentially reducing overall inrush current.

The AXP209 supports ramping up voltages on several regulators such as
DCDC2 and LDO3, therefore we can use the standard 'regulator-ramp-delay'
property for those 2 regulators.
Note that the voltage ramp only works when the regulator is already
enabled. E.g. when going from say 0.7 V to 3.6 V.
When turning on the regulator, no voltage ramp is performed in hardware.
What this means, is that if the bootloader brings up the voltage at 0.7 V,
the ramp delay property is properly applied. If however, the bootloader
leaves the power off, no ramp delay is applied when the power is
enabled by the regulator framework.

Convert the i2c-gpio binding to DT schema format using json-schema. This
serves as an example of how to include other schema (i2c-controller.yaml
in this case).
Signed-off-by: Rob Herring <robh@kernel.org>
Add a how-to doc on writing DT schema documentation. This gives a
description of each section and details on how to validate the DT schema
file. The DT schema are written using json-schema vocabulary in a YAML
encoded document. Using jsonschema gives us access to existing tooling.
A YAML encoding gives us something easy to edit. The example is
annotated to help explain what each section does.
This example is just the tip of the iceberg, but is it the part most
developers writing bindings will interact with. Backing all this up
are meta-schema (to validate the binding schemas), some DT core schema,
YAML encoded DT output with dtc, and a small number of python scripts to
run validation.

This adds the build infrastructure for checking DT binding schema
documents and validating dts files using the binding schema.
Check DT binding schema documents:
make dt_binding_check
Build dts files and check using DT binding schema:
make dtbs_check
Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.
Currently, the validation targets are separate from a normal build to
avoid a hard dependency on the external DT schema project and because
there are lots of warnings generated.

So it looks like folks are interested in dwc3 again. Almost 64% of the

There are two important parts here: a. removal of the waitqueue from

functions can dequeue from any context and; b. better method for
starting isochronous transfers to avoid, as much as possible, missed

The phy-qcom-qmp bindings specified #clock-cells as 1. This was never used
because of_clk_add_provider() was never called, so there was no way anybody
could reference these clocks from DT. Furthermore, even if they could be
accessed, the bindings never specified what should go in that additional
cell.
Fix these incomplete and broken bindings. Move the #clock-cells into the
child node, since that is the actual clock provider, and not all
instances of qcom-qmp-phy are clock providers. Also set #clock-cells to
zero, since there's nothing to pass to it.

This additional specification is needed so that the driver can stop
reaching beyond the tx and rx register allocations to get at the
second lane registers in a dual-lane PHY.
While in there, document #clock-cells as optional for PHYs that don't
provide a pipe clock. Also, document the pcs_misc register region, which
was being quietly supplied and used.

The cpsw-phy-sel driver was replaced with new PHY driver phy-gmii-sel, so
deprecate cpsw-phy-sel bindings and update CPSW binding to use phy-gmii-sel
PHY bindings.

Add DT binding documentation for Sierra PHY. The PHY supports
a number of different protocols, including PCIe and USB.
The PHY lanes may be configured as single or multi-lane links.
Each link is treated as a separate sub-node. For example, if
there are 4 lanes in total the first 2 might be configured as
a multi-lane PCIe link while the other two are single lane
USB links, and in this case there would be 3 sub-nodes.
There are two resets for the PHY block (one for APB register
access, one for the PHY link) and separate resets for each
link. For multi-lane links, the reset corresponds to the
reset line on the master lane, the resets on other lanes
have no effect.

The USB2.0 PHY on Allwinner H6 is similar to the ones on the ones on
older SoCs, but with holes in PHY number (USB1 and USB2 are missing, in
which USB1 is a USB3 PHY).
Add binding for the PHY.
