a5467ebd68 drm/amd/pm: Fix a memory leak in an error handling path in 'vangogh_tables_init()'
'watermarks_table' must be freed instead 'clocks_table', because
'clocks_table' is known to be NULL at this point and 'watermarks_table' is
never freed if the last kzalloc fails.

  - For those changes which had been fed to SMU before S3/S4/Runpm

5810323ba6 drm/amd/pm: Fix a bug communicating with the SMU (v5)
This fixes a bug which if we probe a non-existing
I2C device, and the SMU returns 0xFF, from then on
we can never communicate with the SMU, because the
code before this patch reads and interprets 0xFF
as a terminal error, and thus we never write 0
into register 90 to clear the status (and
subsequently send a new command to the SMU.)

It is not an error that the SMU returns status
0xFF. This means that the SMU executed the last
command successfully (execution status), but the
command result is an error of some sort (execution
result), depending on what the command was.

When doing a status check of the SMU, before we
send a new command, the only status which
precludes us from sending a new command is 0--the
SMU hasn't finished executing a previous command,
and 0xFC--the SMU is busy.

This bug was seen as the following line in the
kernel log,

amdgpu: Msg issuing pre-check failed(0xff) and SMU may be not in the right state!

when subsequent SMU commands, not necessarily
related to I2C, were sent to the SMU.

This patch fixes this bug.

v2: Add a comment to the description of
__smu_cmn_poll_stat() to explain why we're NOT
defining the SMU FW return codes as macros, but
are instead hard-coding them. Such a change, can
be followed up by a subsequent patch.

v3: The changes are,
a) Add comments to break labels in
   __smu_cmn_reg2errno().

b) When an unknown/unspecified/undefined result is
   returned back from the SMU, map that to
   -EREMOTEIO, to distinguish failure at the SMU
   FW.

c) Add kernel-doc to
   smu_cmn_send_msg_without_waiting(),
   smu_cmn_wait_for_response(),
   smu_cmn_send_smc_msg_with_param().

d) In smu_cmn_send_smc_msg_with_param(), since we
   wait for completion of the command, if the
   result of the completion is
   undefined/unknown/unspecified, we print that to
   the kernel log.

v4: a) Add macros as requested, though redundant, to
    be removed when SMU consolidates for all
    ASICs--see comment in code.
    b) Get out if the SMU code is unknown.

v5: Rename the macro names.

c0838d3a93 drm/amdgpu: The I2C IP doesn't support 0 writes/reads
The I2C IP doesn't support writes or reads of 0 bytes.

In order for a START/STOP transaction to take
place on the bus, the data written/read has to be
at least one byte.

That is, you cannot generate a write with 0 bytes,
just to get the ACK from a device, just so you can
probe that device if it is on the bus and so to
discover all devices on the bus--you'll have to
read at least one byte. Writes of 0 bytes generate
no START/STOP on this I2C IP--the bus is not
engaged at all.

Set the I2C_AQ_NO_ZERO_LEN to the existing I2C
quirk tables for Aldebaran, Arcturus, Navi10 and
Sienna Cichlid, and add a quirk table to the I2C
driver which drives the bus when the SMU
doesn't--for instance on Vega20.

ebe57d0c8e drm/amd/pm: Simplify managed I2C transfer functions
Now that we have an I2C quirk table for
SMU-managed I2C controllers, the I2C core does the
checks for us, so we don't need to do them, and so
simplify the managed I2C transfer functions.

Also, for Arcturus and Navi10, fix setting the
command type from "cmd->CmdConfig" to "cmd->Cmd".
The latter is what appears to be taking in
the enumeration I2C_CMD_... as an integer,
not a bit-flag.

For Sienna, the "Cmd" field seems to have been
eliminated, and command type and flags all live in
the "CmdConfig" field--this is left untouched.

Fix: Detect and add changing of direction
bit-flag, as this is necessary for the SMU to
detect the direction change in the 1-d array of
data it gets.

0e2125227e drm/amd/pm: skip PrepareMp1ForUnload message in s0ix
The documentation around PrepareMp1ForUnload message says that
anything sent to SMU after this command would be stalled as the
PMFW would not be in a state to take further job requests.

Technically this is right in case of S3 scenario. But, this might
not be the case during s0ix as the PMC driver would be the last
to send the SMU on the OS_HINT. If SMU gets a PrepareMp1ForUnload
message before the OS_HINT, this would stall the entire S0ix process.

Results show that, this message to SMU is not required during S0ix
and hence skip it.
