The Tegra AGIC interrupt controller is an ARM GIC400 interrupt
controller. Per the ARM GIC device-tree binding, the first address
region is for the GIC distributor registers and the second address
region is for the GIC CPU interface registers. The address space for
the distributor registers is 4kB, but currently this is incorrectly
defined as 8kB for the Tegra AGIC and overlaps with the CPU interface
registers. Correct the address space for the distributor to be 4kB.

Two of the Tegra I2C controllers share pads with the DPAUX controllers.
In order for the I2C controllers to use these pads, they have to be set
into I2C mode. Use the I2C and off pin control states defined in the DT
nodes for DPAUX as "default" and "idle" states, respectively. This
ensures that the I2C controller driver can properly configure the pins
when it needs to perform I2C transactions.

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

HDMI 2.0 or DP 1.2 are available for display, four USB ports (3 USB 2.0
and 1 USB 3.0) can be used to attach a variety of peripherals and a PCI
Ethernet controller provides onboard network connectivity. An M.2 Key-E

- Cleanups about PCM buffer preallocation calls
- Kill NULL device object in memory allocations

ASoC drivers:

- Quite a few improvements to simplify the generic card drivers,
especially the merge of the SCU cards into the main generic drivers
- Lots of fixes for probing on Intel systems to follow more standard
styles
- A big refresh and cleanup of the Samsung drivers
- New drivers: Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341
and CS35L26, Google ChromeOS embedded controllers, Ingenic JZ4725B,
MediaTek BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328,
Spreadtrum DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM

ALSA drivers:

- HD-audio codec quirks for ALC294 S4 resume, ASUS laptop, Chrome

Add SDMMC initial pad offsets used by auto calibration process.
Add SDMMC fixed drive strengths for Tegra210, Tegra186 and
Tegra194 which are used when calibration timeouts.
Fixed drive strengths are based on Pre SI Analysis of the pads.
