Pull tty / serial updates from Greg KH:
"Here is the big set of tty and serial driver patches for 5.14-rc1.
A bit more than normal, but nothing major, lots of cleanups.
Highlights are:
- lots of tty api cleanups and mxser driver cleanups from Jiri
- build warning fixes
- various serial driver updates
- coding style cleanups
- various tty driver minor fixes and updates
- removal of broken and disable r3964 line discipline (finally!)
All of these have been in linux-next for a while with no reported
issues"

Line disciplines expect a positive value or zero returned from
tty->ops->write_room (invoked by tty_write_room). So make this
assumption explicit by using unsigned int as a return value. Both of
tty->ops->write_room and tty_write_room.

tty_unregister_ldisc now returns 0 = success. No need to check the
return value. In fact, the users only warned if an error occured and
didn't do anything useful anyway -- the ldisc module was unloaded in any
case.

Make tty_unregister_ldisc symmetric to tty_register_ldisc by accepting
struct tty_ldisc_ops as a parameter instead of ldisc number. This avoids
checking of the ldisc number bounds in tty_unregister_ldisc.

There is no reason to pass the ldisc number to tty_register_ldisc
separately. Just set it in the already defined tty_ldisc_ops in all the
ldiscs.
This simplifies tty_register_ldisc a bit too (no need to set the num
member there).

Char pointer (cp) passed to tty_ldisc_ops::receive_buf{,2} is const.
There is no reason for flag pointer (fp) not to be too. So switch it in
the definition and all uses.

Since the macro was introduced in 2019 (commit bb6243b4f73d ("drivers:
platform: provide devm_platform_ioremap_resource_wc()") there is only a
single user which hardly justifies the function for the small task it
provides.
So drop the helper and open-code it in the only user. Adapt the non-wc
case accordingly.
For a all-mod-config build on amd64 this change introduces the following
changes according to bloat-o-meter:
add/remove: 0/1 grow/shrink: 1/0 up/down: 20/-252 (-232)
Function old new delta
devm_platform_ioremap_resource_wc 252 - -252
sram_probe 796 816 +20

In preparation for a new feature that allows the user to reserve
signals ahead of submissions, we need to change a current assumption
in the code.
Currently, the driver uses 2 SOBs to support signal CS. When the first
SOB reaches max value, the driver switches to the other one and assumes
that when it will need to switch back to the first one, all of the
signals have already been handled.
This assumption won't hold when the new feature will be added, because
using signal reservation, the driver can reach the max SOB value very
fast.
The change is to add a validity check when submitting a signal CS, to
make sure the previous SOB is available (all the signals attached to
it indeed finished).

We introduce a new type of reset which is reset upon device release.
This reset is very similar to soft reset except the fact it is
performed only upon device release and not upon user sysfs request
nor TDR.
The purpose of this reset is to make sure the device is returned to
IDLE state after the current user has finished working with the device.

In case QMAN has an error and stop_on_err is true, print specific
information of the "offending" command buffer batch.
If the error occurred on one of the higher CPs, the CQ pointer and size
will be printed along with (up to) last 8 PQEs of the stream.
If the error occurred in the lower CP, the CQ pointer and size will be
printed along with (up to) last 8 PQEs of ALL upper CPs as we have no
way to know which upper CP sent the job there.
This is done so higher SW levels will be able to debug their CS by
extracting the raw data of the offending command buffer batch and
examine those offline to detect the issue.

In current code, for dynamic f/w loading flow, DRAM scrambling is
enabled post Linux fit image is loaded to the card. This can cause the
device CPU to go into reset state.
The correct sequence should be:
1. Load boot fit image
2. Enable scrambling
3. Load Linux fit image
This commit aligns the DRAM scrambling enabling with the static f/w load
flow.
