platform/x86: thinkpad_acpi: Add profile force ability

2023-05-17T12:01:54+00:00

commit 1684878952929e20a864af5df7b498941c750f45 upstream.

There has been a lot of confusion around which platform profiles are
supported on various platforms and it would be useful to have a debug
method to be able to override the profile mode that is selected.

I don't expect this to be used in anything other than debugging in
conjunction with Lenovo engineers - but it does give a way to get a
system working whilst we wait for either FW fixes, or a driver fix
to land upstream, if something is wonky in the mode detection logic

platform/x86: thinkpad_acpi: Fix platform profiles on T490

2023-05-17T12:01:54+00:00

commit 0c0cd3e25a5b64b541dd83ba6e032475a9d77432 upstream.

I had incorrectly thought that PSC profiles were not usable on Intel
platforms so had blocked them in the driver initialistion. This broke
platform profiles on the T490.

After discussion with the FW team PSC does work on Intel platforms and
should be allowed.

Note - it's possible this may impact other platforms where it is advertised
but special driver support that only Windows has is needed. But if it does
then they will need fixing via quirks. Please report any issues to me so I
can get them addressed - but I haven't found any problems in testing...yet

platform/x86: touchscreen_dmi: Add upside-down quirk for GDIX1002 ts on the Juno Tablet

commit 6abfa99ce52f61a31bcfc2aaaae09006f5665495 upstream.

The Juno Computers Juno Tablet has an upside-down mounted Goodix
touchscreen. Add a quirk to invert both axis to correct for this.

commit 75e406b540c3eca67625d97bbefd4e3787eafbfe upstream.

Currently when the uncore_write() returns error, it is silently
ignored. Return error to user space when uncore_write() fails.

platform/chrome: cros_typec_switch: Add missing fwnode_handle_put()

[ Upstream commit dc70234c408c644505a24362b0f095f713e4697e ]

In cros_typec_register_switches(), we should add fwnode_handle_put()
when break out of the iteration device_for_each_child_node()
as it will automatically increase and decrease the refcounter.

platform/x86/amd: pmc: Move out of BIOS SMN pair for STB init

2023-05-11T14:17:08+00:00

[ Upstream commit 8d99129eef8f42377b41c1bacee9f8ce806e9f44 ]

The current SMN index used for the driver probe seems to be meant
for the BIOS pair and there are potential concurrency problems that can
occur with an inopportune SMI.

It is been advised to use SMN_INDEX_0 instead of SMN_INDEX_6, which is
what amd_nb.c provides and this function has protections to ensure that
only one caller can use it at a time.

platform/x86/amd: pmc: Move idlemask check into `amd_pmc_idlemask_read`

[ Upstream commit 9217bd1d7699f34a01b26ba14ff38c1714ce1185 ]

The version check requirement for idle mask support actually only
applies to RN/CZN/BRC platforms.

So far no issues have happened because the PMFW version string is
bigger on other supported systems.  This can be reset for any new platform
so move the check to only RN/CZN/BRC case.
