Now that we know the sequence number at bind time, there is no need for

Note: the PCI_CAP_ID_EA code may need a look, but there are no test
failures so I have left it as is.

Some buses have their own rules which require assigning sequence numbers
with a bus-specific algorithm. For example, PCI requires that sub-buses
are numbered higher than their parent buses, meaning effectively that
parent buses must be numbered only after all of their child buses have
been numbered.
Add a uclass flag to indicate that driver model should not assign sequence
numbers. In this case, the uclass must do it.

Checking for seq == -1 is effectively checking that the device is
activated. The new sequence numbers are never -1 for a bound device, so
update the check.
Also drop the note about valid sequence numbers so it is accurate with the
new approach.

Use the new sequence number in all cases. Drop the logic to check for a

Also drop the numbering in the uclass, since we can rely on driver

At present each device has two sequence numbers, with 'req_seq' being
set up at bind time and 'seq' at probe time. The idea is that devices
can 'request' a sequence number and then the conflicts are resolved when
the device is probed.
This makes things complicated in a few cases, since we don't really know
what the sequence number will end up being. We want to honour the
bind-time requests if at all possible, but in fact the only source of
these at present is the devicetree aliases. Since we have the devicetree
available at bind time, we may as well just use it, in the hope that the
required processing will turn out to be useful later (i.e. the device
actually gets used).
Add a new 'sqq' member, the bind-time sequence number. It operates in
parallel to the old values for now. All devices get a valid sqq value,
i.e. it is never -1.
Drop an #ifdef while we are here.

At present this is passed a uclass ID and it has to do a lookup. The
callers all have the uclass pointer, except for the I2C uclass where the
code will soon be deleted.
Update the argument to a uclass * instead of an ID since it is more
efficient.

At present various drivers etc. access the device's 'seq' member directly.
This makes it harder to change the meaning of that member. Change access
to go through a function instead.

This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.
Signed-off-by: Simon Glass <sjg@chromium.org>
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).
Rename some of the latter variables to end with 'plat' for consistency.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

For eMMC HS400 mode, the DLL reset is a required step for mmc rescan.
This step has not been documented in reference manual, but the RM will

In previous commit to support eMMC HS400,
db8f936 mmc: fsl_esdhc: support eMMC HS400 mode
the steps to configure DLL could be found in commit message,
13. Set DLLCFG0[DLL_ENABLE] and DLLCFG0[DLL_FREQ_SEL].
14. Wait for delay chain to lock.
these would be fixed as,
13. Set DLLCFG0[DLL_ENABLE] and DLLCFG0[DLL_FREQ_SEL].
13.1 Write DLLCFG0[DLL_RESET] to 1 and wait for 1us,
then write DLLCFG0[DLL_RESET]
14. Wait for delay chain to lock.
This patch is to add the step of DLL reset, and make sure delay chain
locked for HS400.

mmc_send_cmd_quirks is a helper function to do this retrying behavior. It
