[ Upstream commit bceec87a73804bb4c33b9a6c96e2d27cd893a801 ]

Loading the amd_pmc module as:

    amd_pmc enable_stb=1

...can result in the following messages in the kernel ring buffer:

    amd_pmc AMDI0009:00: SMU cmd failed. err: 0xff
    ioremap on RAM at 0x0000000000000000 - 0x0000000000ffffff
    WARNING: CPU: 10 PID: 2151 at arch/x86/mm/ioremap.c:217 __ioremap_caller+0x2cd/0x340

Further debugging reveals that this occurs when the requests for
S2D_PHYS_ADDR_LOW and S2D_PHYS_ADDR_HIGH return a value of 0,
indicating that the STB is inaccessible. To prevent the ioremap
warning and provide clarity to the user, handle the invalid address
and display an error message.

Some machines like the Dell G15 5155 emit WMI events when
suspending/resuming. Ignore those WMI events.

[ Upstream commit 6f7d0f5fd8e440c3446560100ac4ff9a55eec340 ]

The Lenovo workstations require the password opcode to be run before
the attribute value is changed (if Admin password is enabled).

Tested on some Thinkpads to confirm they are OK with this order too.

[ Upstream commit 2fae3129c0c08e72b1fe93e61fd8fd203252094a ]

x86_android_tablet_remove() frees the pdevs[] array, so it should not
be used after calling x86_android_tablet_remove().

When platform_device_register() fails, store the pdevs[x] PTR_ERR() value
into the local ret variable before calling x86_android_tablet_remove()
to avoid using pdevs[] after it has been freed.

Create a platform_device from module_init() and change

probe() and remove() functions.

This is a preparation patch for refactoring x86_android_tablet_get_gpiod()

The reason for this error is physical_package_ids assigned by VMware VMM
are not continuous and have gaps. This will cause value returned by
topology_physical_package_id() to be more than topology_max_packages().

Here the allocation uses topology_max_packages(). The call to
topology_max_packages() returns maximum logical package ID not physical
ID. Hence use topology_logical_package_id() instead of
topology_physical_package_id().

[ Upstream commit d9dca215708d32e7f88ac0591fbb187cbf368adb ]

While booting, Lenovo 14ARB7 reports 'lenovo-ymc: Unknown key 0 pressed'
warning. This is caused by lenovo_ymc_probe() calling lenovo_ymc_notify()
at probe time to get the initial tablet-mode-switch state and the key-code
lenovo_ymc_notify() reads from the firmware is not initialized at probe
time yet on the Lenovo 14ARB7.

The hardware/firmware does an ACPI notify on the WMI device itself when
it initializes the tablet-mode-switch state later on.

Add 0x0 YMC state to the sparse keymap to silence the warning.

[ Upstream commit a3379eca24a7da5118a7d090da6f8eb8611acac8 ]

There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it
turns out that the 2G version has a DMI product name of
"CHERRYVIEW D1 PLATFORM" where as the 4G version has
"CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are
unique enough that the product-name check is not necessary.

Drop the product-name check so that the existing DMI match for the 4G
RAM version also matches the 2G RAM version.
