- eMMC
- spi flash (assembly option)

Additionally microSD and usb-2.0 otg are included in the SoM

- USB-2.0 Hub
- USB-A Connector
- LEDs
- 2x CAN transceiver
- 1x RS485 transceiver
- sensors

The M.2 connectors support either USB-3.1 or PCI-E depending on status
of a mux. By default the mux is switched off.

 "We still have some races in filesystem methods when exposed to RCU
  pathwalk. This series is a result of code audit (the second round of
  it) and it should deal with most of that stuff.

  Still pending: ntfs3 ->d_hash()/->d_compare() and ceph_d_revalidate().
  Up to maintainers (a note for NTFS folks - when documentation says
  that a method may not block, it *does* imply that blocking allocations
  are to be avoided. Really)"

[ More explanations for people who aren't familiar with the vagaries of
  RCU path walking: most of it is hidden from filesystems, but if a
  filesystem actively participates in the low-level path walking it
  needs to make sure the fields involved in that walk are RCU-safe.

  That "actively participate in low-level path walking" includes things
  like having its own ->d_hash()/->d_compare() routines, or by having
  its own directory permission function that doesn't just use the common
  helpers.  Having a ->d_revalidate() function will also have this issue.

  Note that instead of making everything RCU safe you can also choose to
  abort the RCU pathwalk if your operation cannot be done safely under
  RCU, but that obviously comes with a performance penalty. One common
  pattern is to allow the simple cases under RCU, and abort only if you
  need to do something more complicated.

  So not everything needs to be RCU-safe, and things like the inode etc
  that the VFS itself maintains obviously already are. But these fixes
  tend to be about properly RCU-delaying things like ->s_fs_info that
  are maintained by the filesystem and that got potentially released too

Michal Vokáč [Wed, 14 Feb 2024 09:03:28 +0000 (10:03 +0100)]
ARM: dts: imx6dl-yapp4: Move the internal switch PHYs under the switch node

We identified that the PHYs actually do not work since commit 7da7b84fee58
("ARM: dts: imx6dl-yapp4: Move phy reset into switch node") as
a coincidence of several circumstances.

The reset signal is kept asserted by a pull-down resistor on the board
unless it is deasserted by GPIO from the SoC. This is to keep the switch
dead until it is configured properly by the kernel and user space.

Prior to the referenced commit the switch was reset by the FEC driver
and the reset GPIO was actively deasserted. The mdio-bus was scanned
and the attached switch and its PHYs were found and configured.

With the referenced commit the switch is reset by the qca8k driver.
Because of another bug in the qca8k driver, functionality of the reset
pin depends on its pre-kernel configuration. See commit c44fc98f0a8f
("net: dsa: qca8k: fix illegal usage of GPIO")

The problem did not appear until we removed support for the switch
and configuration of its reset pin from the bootloader.

To fix that, properly describe the internal mdio-bus configuration of
the qca8334 switch. The PHYs are internal to the switch and sit on its
internal mdio-bus.

  The largest change in this set, that bordered on "new development", is
  the fix for the fact that the location of the new qos_class attribute
  did not match the Documentation. The fix ends up deleting more code
  than it added, and it has a new unit test to backstop basic errors in
  this interface going forward. So the "red-diff" and unit test saved
  the "rip it out and try again" response.

  In contrast, the new notification path for firmware reported CXL
  errors (CXL CPER notifications) has a locking context bug that can not
  be fixed with a red-diff. Given where the release cycle stands, it is
  not comfortable to squeeze in that fix in these waning days. So, that
  receives the "back it out and try again later" treatment.

  There is a regression fix in the code that establishes memory NUMA
  nodes for platform CXL regions. That has an ack from x86 folks. There
  are a couple more fixups for Linux to understand (reassemble) CXL
  regions instantiated by platform firmware. The policy around platforms
  that do not match host-physical-address with system-physical-address
  (i.e. systems that have an address translation mechanism between the
  address range reported in the ACPI CEDT.CFMWS and endpoint decoders)
  has been softened to abort driver load rather than teardown the memory
  range (can cause system hangs). Lastly, there is a robustness /
  regression fix for cases where the driver would previously continue in
  the face of error, and a fixup for PCI error notification handling.

  Summary:

   - Fix NUMA initialization from ACPI CEDT.CFMWS

   - Fix region assembly failures due to async init order

   - Fix / simplify export of qos_class information

   - Fix cxl_acpi initialization vs single-window-init failures

   - Fix handling of repeated 'pci_channel_io_frozen' notifications

   - Workaround platforms that violate host-physical-address ==

i2c: imx: when being a target, mark the last read as processed

'processed'. Otherwise index registers of backends may not increase.

ARM: dts: sun8i: Open FETA40i-C regulator aldo1

The USB PHY in the Allwinner R40 SoC seems to rely on voltage on the
VCC-TVIN/OUT supply pins for proper operation, on top of its own supply
voltage on VCC-USB. Without a 3.3V voltage supplied to VCC-TV*, USB
operation becomes unstable and can result in disconnects.

The Forlinx FETA40i-C SoM connects both the VCC-TVOUT and VCC-TVIN pins
to the ALDO1 rail of the PMIC, so we need to enable that rail for USB
operation. Since there is no supply property in the DT bindings for
the USB core, we need to always enable the regulator.

This fixes unstable USB operation on boards using the Forlinx FETA40i-C
module.

 "A simple fix to a definition in the CXL PMU driver, a couple of
  patches to restore SME control registers on the resume path (since
  Arm's fast model now clears them) and a revert for our jump label asm
  constraints after Geert noticed they broke the build with GCC 5.5.

  There was then the ensuing discussion about raising the minimum GCC
  (and corresponding binutils) versions at [1], but for now we'll keep
  things working as they were until that goes ahead.

   - Revert fix to jump label asm constraints, as it regresses the build
     with some GCC 5.5 toolchains.

   - Restore SME control registers when resuming from suspend

   - Fix incorrect filter definition in CXL PMU driver"
