None are dire enough to be Cc'd to stable which may be interpreted to
mean that users of the framework are reaching stability. Lots of new
adoption of this framework is via DeviceTree data and that comes through
the respective architecture and platform trees instead of through the
clk framework tree. Two new features are improved debugfs output and an
improvement to how DT clocks are initialized by reusing a common method.

A simple DRM/KMS driver for the TI LCD Controller found in various
smaller TI parts (AM33xx, OMAPL138, etc). This driver uses the
CMA helpers. Currently only the TFP410 DVI encoder is supported
(tested with beaglebone + DVI cape). There are also various LCD
displays, for which support can be added (as I get hw to test on),
and an external i2c HDMI encoder found on some boards.
The display controller supports a single CRTC. And the encoder+
connector are split out into sub-devices. Depending on which LCD
or external encoder is actually present, the appropriate output
module(s) will be loaded.

The PAMU caches use the LIODNs to determine which cache lines hold the
entries for the corresponding LIODs. The LIODNs must therefore be
carefully assigned to avoid cache thrashing -- two active LIODs with
LIODNs that put them in the same cache line.
Currently, LIODNs are statically assigned by U-Boot, but this has
limitations. LIODNs are assigned even for devices that may be disabled
or unused by the kernel. Static assignments also do not allow for device
drivers which may know which LIODs can be used simultaneously. In
other words, we really should assign LIODNs dynamically in Linux.
To do that, we need to describe the PAMU device and cache topologies in
the device trees.

This patch adds a simple Device Tree binding for the mvsdio driver, as
well as the necessary documentation for it. Compatibility with non-DT
platforms is preserved, by keeping the platform_data based
initialization.
We introduce a small difference between non-DT and DT platforms: DT
platforms are required to provide a clocks = <...> property, which the
driver uses to get the frequency of the clock that goes to the SDIO
IP. The behaviour on non-DT platforms is kept unchanged: a clock
reference is not mandatory, but the clock frequency must be passed in
the "clock" field of the mvsdio_platform_data structure.

The Tegra USB driver has a number of issues:
1) The PHY driver isn't a true platform device, and doesn't implement
the standard USB PHY API.
2) struct device instance numbers were used to make decisions in the
driver, rather than being parameterized by DT or platform data.
This pull request solves issue (2), and lays the groundwork for solving
issue (1). The work on issue (1) involved introducing new DT nodes for
the USB PHYs, which in turn interacted with the Tegra common clock
framework changes, due to the move of clock lookups into device tree.
Hence, these USB driver changes are taken through the Tegra tree with
acks from USB maintainers.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-soc-ccf.

Merge tag 'tegra-for-3.9-soc-usb' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/soc
From Stephen Warren:
ARM: tegra: USB driver cleanup
The Tegra USB driver has a number of issues:
1) The PHY driver isn't a true platform device, and doesn't implement
the standard USB PHY API.
2) struct device instance numbers were used to make decisions in the
driver, rather than being parameterized by DT or platform data.
This pull request solves issue (2), and lays the groundwork for solving
issue (1). The work on issue (1) involved introducing new DT nodes for
the USB PHYs, which in turn interacted with the Tegra common clock
framework changes, due to the move of clock lookups into device tree.
Hence, these USB driver changes are taken through the Tegra tree with
acks from USB maintainers.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-soc-ccf.

Tegra already supports the common clock framework, but had issues:
1) The clock driver was located in arch/arm/mach-tegra/ rather than
drivers/clk/.
2) A single "Tegra clock" type was implemented, rather than separate
clock types for PLL, mux, divider, ... type in HW.
3) Clock lookups by device drivers were still driven by device name
and connection ID, rather than through device tree.
This pull request solves all three issues. This required some DT changes
to add clocks properties, and driver changes to request clocks more
"correctly". Finally, this rework allows all AUXDATA to be removed from
Tegra board files, and various duplicate clock lookup entries to be
removed from the driver.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-cleanup.

Convert MicBias widgets to supply widget.
On tlv320aic3x, Mic bias power on/off shares the same register bits
with output mic bias voltage. So, when power on mic bias, we need
reclaim it to voltage value.
Provide a new platform data so that the micbias voltage can be sent
according to board requirement. Now since tlv320aic3x codec driver
is DT aware, update dt files and functions to handle this new
"micbias-vg" platform data.
Because of sharing of bits, when enabling the micbias, voltage also
needs to be updated. So use SND_SOC_DAPM_POST_PMU & SND_SOC_DAPM_PRE_PMD
macro to create an event to handle this.
Since micbias is converted to supply widget, updated machine drivers as
well.
This change is runtime tested on da850-evm with audio loopback

Currently cfi_cmdset_0002.c does not support PPB locking of sectors. This
patch adds support for this locking/unlocking mechanism. It is needed on
some platforms, since newer U-Boot versions do support this PPB locking
and protect for example their environment sector(s) this way.
This PPB locking/unlocking will be enabled for all devices supported by
cfi_cmdset_0002 reporting 8 in the CFI word 0x49 (Sector Protect/Unprotect
scheme).
Please note that PPB locking does support sector-by-sector locking. But
the whole chip can only be unlocked together. So unlocking one sector
will automatically unlock all sectors of this device. Because of this
chip limitation, the PPB unlocking function saves the current locking
status of all sectors before unlocking the whole device. After unlocking
the saved locking status is re-configured. This way only the addressed
sectors will be unlocked.
To selectively enable this advanced sector protection mechanism, the
device-tree property "use-advanced-sector-protection" has been created.
To enable support for this locking this property needs to be present in the
flash DT node. E.g.:
nor_flash@0,0 {
compatible = "amd,s29gl256n", "cfi-flash";
bank-width = <2>;
use-advanced-sector-protection;
...

The DT binding for the pwm-leds devices are similar to the gpio-leds type.
LEDs are represented as sub-nodes of the pwm-leds device.
The code for handling the DT boot is based on the code found in the
leds-gpio driver and adapted to use PWMs instead of GPIOs.
To avoid having custom cleanup code in case of DT boot the newly created
devm_of_pwm_get() API is used to get the correct PWM instance.
