5eee5ab916 net: dsa: refactor the code to set the port MAC address into a dedicated function
This snippet of code has a bothering "if (...) return 0" in it which
assumes it is the last piece of code running in dsa_port_probe().

This makes it difficult to add further code at the end of dsa_port_probe()
which does not depend on MAC address stuff.

So move the code to a dedicated function which returns void and let the
code flow through.

In commit b24bb99d cp110 configuration initially done in u-boot

That commit didn't account for later introduced in d13b740c SATA invert polarity support.

This patch adds support of passing SATA invert polarity flags to atf

019801863b efi_loader: Fix spec ID event creation
TCG EFI Protocol Specification defines the number_of_algorithms
field in spec ID event to be equal to the number of active
algorithms supported by the TPM device. In current implementation,
this field is populated with the count of all algorithms supported
by the TPM which leads to incorrect spec ID event creation.

Similarly, the algorithm array in spec ID event should be a variable
length array with length being equal to the number_of_algorithms field.
In current implementation this is defined as a fixed length array
which has been fixed.

a partition table is used and the whole disk (partition number 0) doesn't
contain a filesytem. Some partitions may only contain a blob. Not seeing a

a0a5c43193 usb: xhci-pci: Move reset logic out of XHCI core
Resetting an XHCI controller inside xhci_register undoes any register
setup performed by the platform driver. And at least on the Allwinner
H6, resetting the XHCI controller also resets the PHY, which prevents
the controller from working. That means the controller must be taken out
of reset before initializing the PHY, which must be done before calling
xhci_register.

The logic in the XHCI core was added to support the Raspberry Pi 4
(although this was not mentioned in the commit log!), which uses the
xhci-pci platform driver. Move the reset logic to the platform driver,
where it belongs, and where it cannot interfere with other platform
drivers.

This also fixes a failure to call reset_free if xhci_register failed.

ee91d46557 arm: mach-k3: common: Make sure firmware sections are loaded prior to armv8 startup
With Device Manager firmware in an elf file form, we cannot load the FIT
image to the exact same address as any of the executable sections of the
elf file itself is located.

However, the device tree descriptions for the ARMV8 bootloader/OS
includes DDR regions only the final sections in DDR where the Device
Manager firmware is actually executing out of.

As the R5 uC is usually operating at a slower rate than an ARMv8 MPU,
by starting the Armv8 ahead of parsing the elf and copying the correct
sections to the required memories creates a race condition where the
ARMv8 could overwrite the elf image loaded from the FIT image prior to
the R5 completing parsing and putting the correct sections of elf in
the required memory locations. OR create rather obscure debug conditions
where data in the section is being modified by ARMV8 OS while the elf
copy is in progress.

To prevent all these conditions, lets make sure that the elf parse and
copy operations are completed ahead of ARMv8 being released to execute.

We will pay a penalty of elf copy time, but that is a valid tradeoff in
comparison to debug of alternate scenarios.

6887f8e00b arm: mach-k3: am6_init: Prioritize MSMC traffic over DDR in NAVSS Northbridge
NB0 is bridge to SRAM and NB1 is bridge to DDR.

To ensure that SRAM transfers are not stalled due to delays during DDR
refreshes, SRAM traffic should be higher priority (threadmap=2) than
DDR traffic (threadmap=0).

This fixup is critical to provide deterministic access latency to
MSMC from ICSSG, it applies to all AM65 silicon revisions and is due
to incorrect reset values (has no erratum id) and statically setting
things up should be done independent of usecases and board.

This specific style of Northbridge configuration is specific only to
AM65x devices, follow-on K3 devices have different data prioritization
schemes (ASEL and the like) and hence the fixup applies purely to
AM65x.

Without this fix, ICSSG TX lock-ups due to delays in MSMC transfers in
case of SR1 devices, on SR2 devices, lockups were not observed so far
but high retry rates of ICSSG Ethernet (icssg-eth) and, thus, lower
throughput.

cfd50dfb72 clk: ti: k3: Update driver to account for divider flags
The K3 SoCs have some PLL output clocks (POSTDIV clocks) which in
turn serve as inputs to other HSDIV output clocks. These clocks use
the actual value to compute the divider clock rate, and need to be
registered with the CLK_DIVIDER_ONE_BASED flags. The current k3-clk
driver and data lacks the infrastructure to pass in divider flags.
Update the driver and data to account for these divider flags.

d3c56e2a82 clk: ti: k3-pll: Change DIV_CTRL programming to read-modify-write
There are three different divider values in the DIV_CTRL register
controlled by the k3-pll driver. Currently the ti_pll_clk_set_rate
function writes the entire register when programming plld, even though
plld only resides in the lower 6 bits.

Change the plld programming to read-modify-write to only affect the
relevant bits for plld and to preserve the other two divider values
present in the upper 16 bits, otherwise they will always get set to zero
when programming plld.

ae8d3d236a arm: mach-k3: Add note to auto-generated files
Add a note to the automatically generated clk-data and dev-data files
for j721e and j7200 to indicate that they are in fact auto-generated and
should not be hand edited.

Also adjust TI URL to use https instead of http and also add an empty
line before first header inclusion.

326c03b548 arm: mach-k3: j7200: Fix clk-data parenting for postdiv PLL clocks
The TI K3 Fractional PLLs use two programmable POSTDIV1 and POSTDIV2
divisors to generate the final FOUTPOSTDIV clock. These are in sequence
with POSTDIV2 following the POSTDIV1 clock. The current J7200 clock data
has the POSTDIV2 clock as the parent for the POSTDIV1 clock, which is
opposite of the actual implementation. Fix the data by simply adjusting
the register bit-shifts.

The Main PLL1 POSTDIV clocks were also defined incorrectly using Main PLL0
register values, fix these as well.
