platform/x86: intel-vbtn: Allow switch events on Acer Switch Alpha 12

2020-12-30T10:54:28+00:00

commit fe6000990394639ed374cb76c313be3640714f47 upstream.

This 2-in-1 model (Product name: Switch SA5-271) features a SW_TABLET_MODE
that works as it would be expected, both when detaching the keyboard and
when folding it behind the tablet body.

It used to work until the introduction of the allow list at
commit 8169bd3e6e193 ("platform/x86: intel-vbtn: Switch to an allow-list
for SW_TABLET_MODE reporting"). Add this model to it, so that the Virtual
Buttons device announces the EV_SW features again.

platform/x86: mlx-platform: remove an unused variable

2020-12-30T10:54:19+00:00

commit eca6ba20f38cfa2f148d7bd13db7ccd19e88635b upstream.

The only reference to the mlxplat_mlxcpld_psu[] array got removed,
so there is now a warning from clang:

drivers/platform/x86/mlx-platform.c:322:30: error: variable 'mlxplat_mlxcpld_psu' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
static struct i2c_board_info mlxplat_mlxcpld_psu[] = {

Remove the array as well and adapt the ARRAY_SIZE() call
accordingly.

platform/chrome: cros_ec_spi: Don't overwrite spi::mode

2020-12-30T10:53:45+00:00

[ Upstream commit 74639cbf51d7c0304342544a83dfda354a6bd208 ]

There isn't any need to overwrite the mode here in the driver with what
has been detected by the firmware, such as DT or ACPI. In fact, if we
use the SPI CS gpio descriptor feature we will overwrite the mode with
SPI_MODE_0 where it already contains SPI_MODE_0 and more importantly
SPI_CS_HIGH. Clearing the SPI_CS_HIGH bit causes the CS line to toggle
when the device is probed when it shouldn't change, confusing the driver
and making it fail to probe. Drop the assignment and let the spi core
take care of it.

platform/x86: mlx-platform: Fix item counter assignment for MSN2700/ComEx system

platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on some HP x360 models

2020-12-30T10:53:40+00:00

[ Upstream commit a4327979a19e8734ddefbd8bcbb73bd9905b69cd ]

Some HP x360 models have an ACPI VGBS method which sets bit 4 instead of
bit 6 when NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT
collection shows only one other model, the Medion E1239T ever setting bit 4
and it always sets this together with bit 6.

So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.

While at it also prefix all VGBS constant defines with "VGBS_".

Note this wrokaround was first added to the kernel as
commit d823346876a9 ("platform/x86: intel-vbtn: Fix SW_TABLET_MODE always
reporting 1 on the HP Pavilion 11 x360").
After commit 8169bd3e6e19 ("platform/x86: intel-vbtn: Switch to an
allow-list for SW_TABLET_MODE reporting") got added to the kernel this
was reverted, because with the new allow-list approach the workaround
was no longer necessary for the model on which the issue was first
reported.

But it turns out that the workaround is still necessary because some
affected models report a chassis-type of 31 which is on the allow-list.

platform/x86: mlx-platform: Remove PSU EEPROM from MSN274x platform configuration

2020-12-30T10:53:23+00:00

[ Upstream commit 912b341585e302ee44fc5a2733f7bcf505e2c86f ]

Remove PSU EEPROM configuration for systems class equipped with
Mellanox chip Spectrum and ATOM CPU - system types MSN274x. Till now
all the systems from this class used few types of power units, all
equipped with EEPROM device with address space two bytes. Thus, all
these devices have been handled by EEPROM driver "24c02".

There is a new requirement is to support power unit replacement by "off
the shelf" device, matching electrical required parameters. Such device
can be equipped with different EEPROM type, which could be one byte
address space addressing or even could be not equipped with EEPROM.
In such case "24c02" will not work.
