All carried changes to the upstream kernel that are needed to boot it on
TI platforms should be considered tech debt. Changes to the default ARMv8
configuration are no different. We need to reduced these over time by
working to get these options in the upstream defconfig. To start to see
where we stand today, lets remove all the options that do not change the
upstream default. Then anything remaining in this file should be
investigated for appropriateness in upstream and sent accordingly.

While pruning is useful for making small and fast-building kernels for
our SDK releases, these are not so useful for general purpose or distro
kernels where these options might still be needed.

For these cases one would only want to apply our additions to gain
support for our platforms but not trim out support for others. To make
this separation clean, move all the pruning from baseport.cfg into
multi_v7_prune.cfg.

The K3 platforms configure the DMA resources with the
help of the TI's System Firmware's Device Manager(DM)
over TISCI. The group of DMA related Resource Manager[1]
TISCI messages includes: INTA, RINGACC, UDMAP, and PSI-L.
This configuration however, does not persist in the DM
after leaving from Suspend-to-RAM state. We have to restore
the DMA channel configuration over TISCI for all configured
channels when entering suspend.

The TISCI resource management calls for each DMA type (UDMA,
PKTDMA, BCDMA) happen in device_free_chan_resources() and
device_alloc_chan_resources(). In pm_suspend() we store
the current udma_chan_config for channels that still have
attached clients and call device_free_chan_resources().
In pm_resume() restore the udma_channel_config from backup
and call device_alloc_chan_resources() for those channels.
Drivers like CPSW do their own DMA resource management,
so use the late system suspend/resume hooks.

commit 5fc6b1b6 upstream.

The AM62A SoC belongs to the K3 Multicore SoC architecture platform that
can run edge AI applications with Video/Vision processing. This provides
advanced system integration with high security support to enable a broad
set of applications in industrial/automotive markets such as, driver
monitoring, machine vision, smart camera, eMirror, front camera,
robotics, and building automation.

Some highlights of AM62A SoC are:
* Quad-Cortex-A53s (running up to 1.4GHz) in a single cluster. Dual/Single
  core variants are provided in the same package to allow HW compatible
  designs.
* One Device manager Cortex-R5F for system power and resource management, and
  one Cortex-R5F for Functional Safety or general-purpose usage.
* One AI accelerator (up to 2 TOPS), using one C7x256V DSP w/Matrix Multiplier
  accelerator (MMA) for Deep Learning usage.
* VPAC3L(Vision Pre-processing Accelerator), providing 12-bit ISP up to
  315MPixel/s RGB+IR support, and Noise Filter for improved integrated imaging
  and vision image processing.
* H.264/H.265 Video Encode/Decode. + Motion JPEG encode
* Display support, providing 24-bit RBG parallel interface up to 200MHz pixel
  clock support for 2K display resolution.
* Integrated Giga-bit Ethernet switch supporting up to a total of two external
  ports (TSN capable).
* 9xUARTs, 5xSPI, 6xI2C, 2xUSB2, 3xCAN-FD, 3x eMMC and SD, GPMC for NAND/FPGA
  connection, OSPI memory controller, 3x McASP for audio, 1x CSI-RX-4L for
  Camera, eCAP/eQEP, ePWM, among other peripherals.
* Dedicated Centralized Hardware Security Module with support for secure boot,
  debug security and crypto acceleration and trusted execution environment
* One 32 bit DDR Subsystem that supports LPDDR4, DDR4 memory types.
* Multiple low power modes support, ex: Deep sleep, Standby, MCU-only, enabling
  battery powered system design.

commit 1607e6f9

 upstream.

Add pinctrl macros for AM62AX SoCs. These macro definitions are similar
to that of previous platforms, but adding new definitions to avoid any
naming confusions in the SoC dts files.

checkpatch insists the following error exists:
ERROR: Macros with complex values should be enclosed in parentheses

However, we do not need parentheses enclosing the values for this
macro as we do intend it to generate two separate values as has been
done for other similar platforms.
