88b697fb37 clk: microchip: mpfs: fix periph clk parentage
Not all "periph" clocks are children of the AHB clock, some have the AXI
clock as their parent & the mtimer clock is derived from the external
reference clock directly. Stop assuming the AHB clock to be the parent

32cfdd5163 clk: microchip: mpfs: fix reference clock handling
The original devicetrees for PolarFire SoC messed up & defined the
msspll's output as a fixed-frequency, 600 MHz clock & used that as the
input for the clock controller node. The msspll is not a fixed
frequency clock and later devicetrees handled this properly. Check the
devicetree & if it is one of the fixed ones, register the msspll.
Otherwise, skip registering it & pass the reference clock directly to
the cfg clock registration function so that existing devicetrees are
not broken by this change.

As the MSS PLL is not a "cfg" or a "periph" clock, add a new driver for
it, based on the one in Linux.

fb103971fe clk: microchip: mpfs: convert parent rate acquistion to get_get_rate()
Currently the clock driver for PolarFire SoC takes a very naive approach
to the relationship between clocks. It reads the dt to get an input
clock, assumes that that is fixed frequency, reads the "clock-frequency"
property & uses that to set up both the "cfg" and "periph" clocks.

Simplifying for the sake of incremental fixes, the "correct" parentage for
the clocks currently supported in U-Boot is that the "cfg" clocks should
be children of the fixed frequency clock in the dt. The AHB clock is one
of these "cfg" clocks and is the parent of the "periph" clocks.

Instead of passing the clock rate of the fixed-frequency clock to the
"cfg" and "periph" registration functions and the name of the parents,
pass their actual parents & use clk_get_rate() to determine their parents
rates.

The "periph" clocks are purely gate clocks and should not be reading the
AHB clocks registers to determine their rates, as they can simply report
the output of clk_get_rate() on their parent.

A late ack is currently being sent at the end of a transfer due to
incorrect logic in mchp_corei2c_empty_rx(). Currently the Assert Ack
bit is being written to the controller's control reg after the last

Instead, the AA flag should be written to the control register when
the penultimate byte is read so it is sent out for the last byte.

At present there is no uclass for this. The devices are attached to the

is confusing.

Block devices should be attached to a 'media' device instead, something
which handles access to the actual media and provides the block driver
for the block device.

Create a new uclass to handle this. It supports two operations, to attach
and detach a file on the host machine.

5ea894ac42 dm: test: Clear the block cache after running a test
Some tests access data in block devices and so cause the cache to fill
up. This results in memory being allocated.

Some tests check the malloc usage at the beginning and then again at the
end, to ensure there is no memory leak caused by the test. The block cache
makes this difficult, since the any test may cause entries to be allocated
or even freed, if the cache becomes full.

It is simpler to clear the block cache after each test. This ensures that
it will not introduce noise in tests which check malloc usage.

Add the logic to clear the cache, using the existing blkcache_invalidate()
function. Drop the duplicate code at the same time.

timer IP with interrupt functionality, and is used in some SoCs from
various vendors.

Add a simple DM compliant timer driver, to allow users of the SP804 to

This relies on the input clock to be accessible via the DM clock
framework, which should be fine as we probably look at fixed-clock's
here anyway.
We re-program the control register in the probe() function, but keep
the divider in place, in case this has been set to something on purpose
before.

At the time of update, the metadata is read to identify the bank to
which the images need to be flashed(update bank). On a successful
update, the metadata is modified to set the updated bank as active
bank to subsequently boot from.

updatable images is stored as part of the metadata, which is stored on
a dedicated partition. Add the metadata structure, and a driver model
uclass which provides functions to access the metadata. These are
generic API's, and implementations can be added based on parameters
like how the metadata partition is accessed and what type of storage
device houses the metadata.

879a9416d1 dm: blk: mmc: Tidy up some Makefile rules for SPL
Use the correct SPL_TPL_ variable so that these features can be enabled in
TPL and VPL as needed.

Disable it by default in TPL to avoid any code-size increase. No boards
are actually using it since the Makefile rules don't allow including
drivers/block/ with TPL_DM enabled. It can be manually enabled as needed.
