8a703a728a arm64: defconfig: Enable USB2 PHY Driver
The USB controller on TI SoCs such as AM65x needs the
USB2 PHY driver to communicate with VBUS/ID comparator.
So enable the OMAP USB2 PHY driver.

2f79e7408a arm64: dts: ti: k3-am69-sk: Add PCIe support
The AM69-SK board has 3 instances of PCIe namely PCIe0, PCIe1 and PCIe3.
The x4 PCIe0 instance is connected to a Card Edge connector via SERDES1.
The x2 PCIe1 instance is connected to an M.2 M Key connector via SERDES0.
The x1 PCIe3 instance is connected to an M.2 E Key connector via SERDES0.

8ec9ce361d arm64: dts: ti: k3-am65-main: Add PRU system events for virtio
A PRU system event "vring" has been added to each PRU and RTU
node in each of the ICSSG0, ICSSG1 and ICSSG2 remote processor
subsystems to enable the virtio/rpmsg communication between MPU
and that PRU/RTU core. The additions are done in the base
k3-am65-main.dtsi, and so are inherited by all the K3 AM65x
boards.

The PRU system events is the preferred approach over using TI
mailboxes, as it eliminates an external peripheral access from
the PRU/RTU-side, and keeps the interrupt generation internal to
the ICSSG. The difference from MPU would be minimal in using one
versus the other.

Mailboxes can still be used if desired, but currently there is
no support on firmware-side for K3 SoCs to use mailboxes. Either
approach would require that an appropriate firmware image is
loaded/booted on the PRU.

12a29fb4f9 arm64: boot: dts: ti: k3-*: Add memory node to bootloader stage
Add the bootph-all property to the memory node so that it can be
accessed by FDT functions at bootloader stage.

The bootloader requires the memory node to be able to initialize and set
the size of the DRAM banks. For this purpose, make sure all memory nodes
are present and standardized, and modify them if not.

The RS485 transceiver RE (Receiver enable) and DE (Driver enable) are
shorted and connected to both RTS/CTS of the SoC UART.
RE is active-low, DE is active-high.

Remove the "rs485-rts-active-low" flag to match RTS polarity with DE,
and fix communication in both transmit and receive directions.

We missed to cover sanity_check_extent_cache() w/ extent cache lock,
so, below race case may happen, result in use after free issue.

- f2fs_iget
 - do_read_inode
  - f2fs_init_read_extent_tree
  : add largest extent entry in to cache
					- shrink
					 - f2fs_shrink_read_extent_tree
					  - __shrink_extent_tree
					   - __detach_extent_node
					   : drop largest extent entry
  - sanity_check_extent_cache
  : access et->largest w/o lock

let's refactor sanity_check_extent_cache() to avoid extent cache access
and call it before f2fs_init_read_extent_tree() to fix this issue.

So Macro IOPRIO_PRIO_LEVEL is more accurate to get ckpt thread

Besides, change variable name from "data" to "level" for more readable.
