8412b4563e cpufreq: Specify default governor on command line
Currently, the only way to specify the default CPUfreq governor is
via Kconfig options, which suits users who can build the kernel
themselves perfectly.

However, for those who use a distro-like kernel (such as Android,
with the Generic Kernel Image project), the only way to use a
non-default governor is to boot to userspace, and to then switch
using the sysfs interface. Being able to specify the default governor
on the command line, like is the case for cpuidle, would allow those
users to specify their governor of choice earlier on, and to simplify
the userspace boot procedure slighlty.

To support this use-case, add a kernel command line parameter
allowing the default governor for CPUfreq to be specified, which
takes precedence over the built-in default.

This implementation has one notable limitation: the default governor
must be registered before the driver. This is solved for builtin
governors and drivers using appropriate *_initcall() functions. And
in the modular case, this must be reflected as a constraint on the
module loading order.

f473bf398b cpufreq: intel_pstate: Allow raw energy performance preference value
Currently using attribute "energy_performance_preference", user space can
write one of the four per-defined preference string. These preference
strings gets mapped to a hard-coded Energy-Performance Preference (EPP) or
Energy-Performance Bias (EPB) knob.

These four values are supposed to cover broad spectrum of use cases, but
are not uniformly distributed in the range. There are number of cases,
where this is not enough. For example:

Suppose user wants more performance when connected to AC. Instead of using
default "balance performance", the "performance" setting can be used. This
changes EPP value from 0x80 to 0x00. But setting EPP to 0, results in
electrical and thermal issues on some platforms. This results in
aggressive throttling, which causes a drop in performance. But some value
between 0x80 and 0x00 results in better performance. But that value can't
be fixed as the power curve is not linear. In some cases just changing EPP
from 0x80 to 0x75 is enough to get significant performance gain.

Similarly on battery the default "balance_performance" mode can be
aggressive in power consumption. But picking up the next choice
"balance power" results in too much loss of performance, which results in
bad user experience in use cases like "Google Hangout". It was observed
that some value between these two EPP is optimal.

This change allows fine grain EPP tuning for platform like Chromebook or
for users who wants to fine tune power and performance.
Here based on the product and use cases, different EPP values can be set.
This change is similar to the change done for:
/sys/devices/system/cpu/cpu*/power/energy_perf_bias
where user has choice to write a predefined string or raw value.

The change itself is trivial. When user preference doesn't match
predefined string preferences and value is an unsigned integer and in
range, use that value for EPP. When the EPP feature is not present
writing raw value is not supported.

ed7bde7a6d cpufreq: intel_pstate: Allow enable/disable energy efficiency
By default intel_pstate the driver disables energy efficiency by setting
MSR_IA32_POWER_CTL bit 19 for Kaby Lake desktop CPU model in HWP mode.
This CPU model is also shared by Coffee Lake desktop CPUs. This allows
these systems to reach maximum possible frequency. But this adds power
penalty, which some customers don't want. They want some way to enable/
disable dynamically.

So, add an additional attribute "energy_efficiency" under
/sys/devices/system/cpu/intel_pstate/ for these CPU models. This allows
to read and write bit 19 ("Disable Energy Efficiency Optimization") in
the MSR IA32_POWER_CTL.

This attribute is present in both HWP and non-HWP mode as this has an
effect in both modes. Refer to Intel Software Developer's manual for
details.

The scope of this bit is package wide. Also these systems are single
package systems. So read/write MSR on the current CPU is enough.

The energy efficiency (EE) bit setting needs to be preserved during
suspend/resume and CPU offline/online operation. To do this:
- Restoring the EE setting from the cpufreq resume() callback, if there
is change from the system default.
- By default, don't disable EE from cpufreq init() callback for matching
CPU models. Since the scope is package wide and is a single package
system, move the disable EE calls from init() callback to
intel_pstate_init() function, which is called only once.

d5ff5fb977 Merge series "Introduce PMIC based USB type C detection" from Wesley Cheng <wcheng@codeaurora.org>:
Changes in v4:
 - Modified qcom,pmic-typec binding to include the SS mux and the DRD remote
   endpoint nodes underneath port@1, which is assigned to the SSUSB path
   according to usb-connector
 - Added usb-connector reference to the typec dt-binding
 - Added tags to the usb type c and vbus nodes
 - Removed "qcom" tags from type c and vbus nodes
 - Modified Kconfig module name, and removed module alias from the typec driver

Changes in v3:
 - Fix driver reference to match driver name in Kconfig for
   qcom_usb_vbus-regulator.c
 - Utilize regulator bitmap helpers for enable, disable and is enabled calls in
   qcom_usb_vbus-regulator.c
 - Use of_get_regulator_init_data() to initialize regulator init data, and to
   set constraints in qcom_usb_vbus-regulator.c
 - Remove the need for a local device structure in the vbus regulator driver

Changes in v2:
 - Use devm_kzalloc() in qcom_pmic_typec_probe()
 - Add checks to make sure return value of typec_find_port_power_role() is
   valid
 - Added a VBUS output regulator driver, which will be used by the PMIC USB
   type c driver to enable/disable the source
 - Added logic to control vbus source from the PMIC type c driver when
   UFP/DFP is detected
 - Added dt-binding for this new regulator driver
 - Fixed Kconfig typec notation to match others
 - Leave type C block disabled until enabled by a platform DTS

Add the required drivers for implementing type C orientation and role
detection using the Qualcomm PMIC.  Currently, PMICs such as the PM8150B
have an integrated type C block, which can be utilized for this.  This
series adds the dt-binding, PMIC type C driver, and DTS nodes.

The PMIC type C driver will register itself as a type C port w/ a
registered type C switch for orientation, and will fetch a USB role switch
handle for the role notifications.  It will also have the ability to enable
the VBUS output to any connected devices based on if the device is behaving
as a UFP or DFP.

a2b782d59c Merge series "ASoC: ti: Add support for audio on J721e EVM" from Peter Ujfalusi <peter.ujfalusi@ti.com>:
Hi,

Changes since v3:
- Fix the single clock source handling and typo

Changes since v2:
- DT binding:
 - use proper (?) patch subject for the binding docuemtn patch
 - drop pll4 and pll15 from DT - driver should check the rate via
   clk_get_parent. If it is not available (as it is not currently) then use the
   match_data provided rates.
 - add simple explanation for the clocking setup
 - Use descriptive names for clocks: cpb/ivi-mcasp-auxclk and cpb/ivi-codec-scki
 - dt_binding_check shows no errors/warnings
- ASoC machine driver:
 - Try to read the PLL4/15 rate with clk API (parent of the two clock divider)
   if it is not available then use the match_data provided numbers.
 - Support for single PLL setup

Changes since v1:
- Fixed DT binding documentation errors
- Rebased on ASoC head and updated the driver to compile and work

This series adds support for the analog audio setup on the j721e EVM.
The audio setup of the EVM is:
Common Processor Board (CPB): McASP10 <-> pcm3168a
Infotainment Expansion Board (IVI): McASP0 <-> 2x pcm3168a

Both CPB and IVI wired in parallel serializer setup.

The first patch adds the stream_name for McASP driver as it is needed in
multicodec (and would be needed in DPCM) setup for proper DAPM handling.

The second patch adds two DT schema, one for the cpb and one for the cpb+ivi
card.

Regards,
Peter

8142500e7d ASoC: dt-bindings: Add documentation for TI j721e EVM (CPB and IVI)
The audio support on the Common Processor Board board is using
pcm3168a codec connected to McASP10 serializers in parallel setup.

The Infotainment board plugs into the Common Processor Board, the support
of the extension board is extending the CPB audio support by adding
the two codecs on the expansion board.

The audio support on the Infotainment Expansion Board consists of McASP0
connected to two pcm3168a codecs with dedicated set of serializers to each.
The SCKI for pcm3168a is sourced from j721e AUDIO_REFCLK0 pin.

upstream toolchain that can create unicore32 binaries and all the links to
prebuilt toolchains for unicore32 are dead. Even compilers that were

Guenter Roeck says:

  that support for it has not been removed from the kernel.

ac3a68d566 net: phy: don't abuse devres in devm_mdiobus_register()
We currently have two managed helpers for mdiobus - devm_mdiobus_alloc()
and devm_mdiobus_register(). The idea behind devres is that the release
callback releases whatever resource the devm function allocates. In the
mdiobus case however there's no devres associated with the device by
devm_mdiobus_register(). Instead the release callback for
devm_mdiobus_alloc(): _devm_mdiobus_free() unregisters the device if
it is marked as managed.

This all seems wrong. The managed structure shouldn't need to know or
care about whether it's managed or not - and this is the case now for
struct mii_bus. The devres wrapper should be opaque to the managed
resource.

This changeset makes devm_mdiobus_alloc() and devm_mdiobus_register()
conform to common devres standards: devm_mdiobus_alloc() allocates a
devres structure and registers a callback that will call mdiobus_free().
__devm_mdiobus_register() allocated another devres and registers a
callback that will unregister the bus.

dee9c0b575 dt-bindings: copy process-schema-examples.yaml to process-schema.yaml
There are two processed schema files:

 - processed-schema-examples.yaml

    Used for 'make dt_binding_check'. This is always a full schema.

 - processed-schema.yaml

    Used for 'make dtbs_check'. This may be a full schema, or a smaller
    subset if DT_SCHEMA_FILES is given by a user.

If DT_SCHEMA_FILES is not specified, they are the same. You can copy
the former to the latter instead of running dt-mk-schema twice. This
saves the cpu time a lot when you do 'make dt_binding_check dtbs_check'
because building the full schema takes a couple of seconds.

If DT_SCHEMA_FILES is specified, processed-schema.yaml is generated
based on the specified yaml files.

fa714cf58c dt-bindings: fix error in 'make clean' after 'make dt_binding_check'
We are having more and more schema files.

Commit 8b6b80218b ("dt-bindings: Fix command line length limit
calling dt-mk-schema") fixed the 'Argument list too long' error of
the schema checks, but the same error happens while cleaning too.

'make clean' after 'make dt_binding_check' fails as follows:

  $ make dt_binding_check
    [ snip ]
  $ make clean
  make[2]: execvp: /bin/sh: Argument list too long

  make[1]: *** [scripts/Makefile.clean:66: Documentation/devicetree/bindings] Error 2
  make: *** [Makefile:1763: _clean_Documentation] Error 2

'make dt_binding_check' generates so many .example.dts, .dt.yaml files,
which are passed to the 'rm' command when you run 'make clean'.

I added a small hack to use the 'find' command to clean up most of the
build artifacts before they are processed by scripts/Makefile.clean
