We've introduced power management logics for the Spreadtrum serial
controller by commit 062ec2774c8a ("serial: sprd: Add power management
for the Spreadtrum serial controller"), thus add related clock properties
to support this feature.

arm64: tegra: Device tree fixes for v5.2-rc1
This contains one patch to disable the recently added XUSB support on
Jetson TX2 which is reported to cause boot and CPU hotplug failures in
some cases and doesn't allow the core power rail to be switched off.
Furthermore there are some changes to enable IOMMU support on more
devices. This is needed in order to prevent these devices from breaking
with the policy change in the ARM SMMU driver to break insecure devices
that is currently headed for v5.2.

The recently introduced XUSB support for Jetson TX2 is causing boot, CPU
hotplug and suspend/resume failures according to several reports.
Temporarily work around this by disabling the XUSB controller and XUSB
pad controller nodes in device tree, while we figure out what's causing
this.

Commit 954a03be033c ("iommu/arm-smmu: Break insecure users by disabling
bypass by default") intentionally breaks all devices using the SMMU in
bypass mode. This breaks, among other things, PCI support on Tegra186.
Fix this by populating the iommus property and friends for the PCIe
controller.

v2 of "clk: imx: Refactor entire sccg pll clk" dropped the implicit
reparenting of the PLL output from the bypass clock to the real
PLL. The commit introducing the GPU node had only been tested against
v1 of this patch. Without an explicit reparent to the real PLL the
GPU is stuck at the bypass clock rate of 25MHz, serverly hampering
performance.

This is very similar to imx8mq cpufreq-dt support.
Operating points are from datasheet:

Higher opps were omitted (just like imx8mq) because it requires checking

The Zii Ultra design, also known as RDU3, is the i.MX8M based successor
to the the i.MX6 based RDU2. This adds the basic board support for all
components which are supported by the upstream kernel at this time.
The board comes in 2 different versions, called RMB3 and Zest, which
are derived from the same design, but have different layouts and a
few small differences in the populated components.

According to NXP's FAE feedback and a comment in ATF firmware, PCIE1
and PCIE2 power domains can't really be used independently. Due to
shared reset line both power domains have to be turned on at the same
time. Account for that quirk by combining PCIE power domains into a
single 'pgc_pcie' power domain.

The i.MX8M Mini is new SOC of the i.MX8M family. it is
focused on delivering the latest and greatest video and
audio experience combining state-of-the-art media-specific
features with high-performance processing while optimized
for lowest power consumption. The i.MX 8M Mini Media Applications
Processor is 14nm FinFET product of the growing i.MX8M family
targeting the consumer & industrial market. It is built in 14LPP
to achieve both high performance and low power consumption
and relies on a powerful fully coherent core complex based on
a quad Cortex-A53 cluster with video and graphics accelerators
This patch adds the basic dtsi support for i.MX8MM.

The driver now uses the 'reg' property to determine the bus and

The main Audio DAC used on the EVK board is wm8524
The EVK provides the MCLK to wm8524.
Digital interface is SAI2 which includes three signals:
SYNC_CLK, BCLK and DACDAT.
This patch sets:
* SAI2 pinctrl configuration
* clock hierarchy
* wm8524 codec
Then uses simple-card machine driver to connect them
into a sound card.
