Confine the memory map changes into a separate rtos-memory-map.dts
which describes the common memory map for all RTOS remoteprocs.

vision-apps.dtbo uses this and also disables capture and display
related peripherals from Linux so that it can be used by RTOS.

edgeai-apps.dtbo expects these devices to be owned by linux, so
it uses the rtos-memory-map customization only.

The parent's input irq number is wrongly subtracted with 32 instead of
using the exact numbers in:

The GPIO interrupts are not working because of that. The toggling works

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.

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

Vaishnav Achath authored 2 years ago and Vignesh Raghavendra committed 2 years ago

In MCSPI controller EOW interrupt is triggered when the channel has
transmitted the set number of bytes in MCSPI_XFERLEVEL[31-16] WCNT,
this can be used to signal the completion of a TX/RX when the internal
FIFO is enabled, when DMA is enabled the internal FIFO is always enabled.
Waiting for the DMA completion adds unpredictable delays due to the
non-realtime completion calculation mechanism.

This commit removes the dma_tx_completion and dma_rx_completion
and relies on the MCSPI controller EOW interrupt to signal transaction
completion.This fixes the real-time performance issues in master and
slave mode when DMA was enabled which resulted from the DMA completion
calculation delays.

Since the MCSPI driver now uses internal mechanism to identify a transfer
completion we disable the TX and RX DMA completion callback and remove
DMA_PREP_INTERRUPT.

If the DMA consumer driver does not expect the callback for TX done, then
we need not perform the channel RT byte counter calculations and estimate
the completion but return complete on first attempt itself.This assumes
that the consumer who did not request DMA_PREP_INTERRUPT has its own
mechanism for understanding TX completion, example: MCSPI EOW interrupt
can be used as TX completion signal for a SPI transaction.
