Do not set 'HCI_UART_PROTO_READY' before call 'hci_uart_register_dev()'.
Possible race is when someone calls 'hci_tty_uart_close()' after this bit
is set, but 'hci_uart_register_dev()' wasn't done. This leads to access
to uninitialized fields. To fix it let's set this bit after device was
registered (as before patch c411c62cc133) and to fix previous problem let's
add one more bit in addition to 'HCI_UART_PROTO_READY' which allows to
perform power up without original bit set (pls see commit c411c62cc133).

'hci_register_dev()' calls power up function, which is executed by
kworker - 'hci_power_on()'. This function does access to bluetooth chip
using callbacks from 'hci_ldisc.c', for example 'hci_uart_send_frame()'.
Now 'hci_uart_send_frame()' checks 'HCI_UART_PROTO_READY' bit set, and
if not - it fails. Problem is that 'HCI_UART_PROTO_READY' is set after
'hci_register_dev()', and there is tiny chance that 'hci_power_on()' will
be executed before setting this bit. In that case HCI init logic fails.
Patch moves setting of 'HCI_UART_PROTO_READY' before calling function
'hci_uart_register_dev()'.

PHYs that are within copper SFP modules have their MDIO bus accessible
through address 0x56 (usually) on the i2c bus. The MDIO-I2C bridge is
desgned for 16 bits accesses, but we can also perform 8bits accesses by
reading/writing the high and low bytes sequentially.
This commit adds support for this type of accesses, thus supporting
smbus controllers such as the one in the VSC8552.
This was only tested on Copper SFP modules that embed a Marvell 88e1111

The SFP module's eeprom and internals are accessible through an i2c bus.
It is possible that the SFP might be connected to an SMBus-only
controller, such as the one found in some PHY devices in the VSC85xx
family.
Introduce a set of sfp read/write ops that are going to be used if the
i2c bus is only capable of doing smbus byte accesses.
As Single-byte SMBus transaction go against SFF-8472 and breaks the
atomicity for diagnostics data access, hwmon is disabled in the case
of SMBus access.
Moreover, as this may cause other instabilities, print a warning at
probe time to indicate that the setup may be unreliable because of the
hardware design.
As hwmon may be disabled for both broken EEPROM and smbus, the warnings
are udpated accordingly.

Also, improve the message in prep_encoded_data() - it now prints
good/bad checksums, and checksum type.

DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.
No functional changes here, but saves some comments during reviews of
new patches built on existing code.

__bch2_read, before calling __bch2_read_extent(), sets bvec_iter.bi_size
to "the size we can read from the current extent" with a swap, and
restores it to "the size for the total read" after the read_extent call
with another swap.
But we neglected to do the restore before the "if (ret) goto err;" -
which is a problem if we're retrying those errors.

We now always set vrr.flipline, vmin, and vmax for all platforms that
support VRR. Therefore, we should set all TRANS_VRR_CTL bits except
VRR_ENABLE. Without this, the readback for these bits will fail because we
only read vrr.flipline, vmin, and vmax if TRANS_VRR_CTL has the
FLIPLINE_EN bit set.
For platforms that always have the VRR Timing Generator enabled,
the FLIPLINE_EN bit is always set in TRANS_VRR_CTL during
intel_transcoder_vrr_enable(). However, for the remaining platforms
(that do not always have the VRR Timing Generator enabled) if a full
modeset doesn't occur and VRR is not enabled, the bit is not set.
This results in a mismatch between the software state and hardware state
because the software state expects VRR timings like flipline, vmin, and
vmax to be set, but the readout for these doesn't happen since the
FLIPLINE_EN bit is not set in TRANS_VRR_CTL.
To avoid this mismatch, write trans_vrr_ctl in
intel_vrr_set_transcoder_timings() even when VRR is not enabled
for platforms that do not have the VRR Timing Generator always enabled.

Currently, the VRR timing generator is used only when VRR is enabled by
userspace for sinks that support VRR. Starting with PTL+, gradually move
away from the legacy timing generator and use the VRR timing generator
for both variable and fixed timings.
Note: For platforms where we always enable the VRR timing generator,
the LRR fastset is not allowed to avoid live programming of vrr.guardband
with VRR TG enabled. This effectively breaks the LRR fastset functionality
for these platforms and needs to be addressed.
v2: Use this for PTL for now to avoid losing LRR fastset for older
platforms. (Ville)

VRR with joiner is currently disabled as it still needs some work to
correctly sequence the primary and secondary transcoders. However, we can
still use VRR Timing generator in fixed refresh rate for joiner and since
it just need to program vrr timings once and does not involve changing
timings on the fly. We still need to skip the VRR and LRR for joiner.
To achieve this set vrr.in_range to 0 for joiner case, so that we do not
try VRR and LRR for the joiner case.
v2: Avoid checks for secondary pipes, where not required. (Ville)
v3: Remove a redundant check and reset vrr.in_range to false. (Ville)

Since the vrr.guardband can now change for platforms that always use the
VRR Timing Generator, and it is unsafe to reprogram the guardband on the
fly, move the guardband and pipeline_full checks from the pure !fastboot
path and add a check for intel_vrr_always_use_vrr_tg().
For older platforms the vrr.guardband change happens when VRR Timing
generator is off. For the platforms that always use the VRR Timing
Generator, this will prevent reprogramming the vrr.guardband without a
full modeset. However, this will disrupt LRR functionality for these
platforms.
v2: Modify the check to avoid breaking the LRR on older platform.
(Ville)
v3: Correct the oversight of not removing the lines from the original
location. (Ville)
