The timeout link table works in HIP08 ES version and the hns driver only
support the CS version for HIP08, so delete the related code. Then
simplify the buffer allocation for link table to make the code more
readable.

It is possible that RX TIMEOUT is signalled after RX FIFO has been
drained, in which case a dummy read of RX FIFO is required to clear RX
TIMEOUT condition. Otherwise, RX TIMEOUT condition is not cleared
leading to an interrupt storm

Aspeed Virtual UARTs directly bridge e.g. the system console UART on the
LPC bus to the UART interface on the BMC's internal APB. As such there's
no RS-232 signalling involved - the UART interfaces on each bus are
directly connected as the producers and consumers of the one set of
FIFOs.
The APB in the AST2600 generally runs at 100MHz while the LPC bus peaks
at 33MHz. The difference in clock speeds exposes a race in the VUART
design where a Tx data burst on the APB interface can result in a byte
lost on the LPC interface. The symptom is LSR[DR] remains clear on the
LPC interface despite data being present in its Rx FIFO, while LSR[THRE]
remains clear on the APB interface as the host has not consumed the data
the BMC has transmitted. In this state, the UART has stalled and no
further data can be transmitted without manual intervention (e.g.
resetting the FIFOs, resulting in loss of data).
The recommended work-around is to insert a read cycle on the APB
interface between writes to THR.

The transition of the QP state from SQD to RTS is allowed by the IB
specification. The hardware also supports that, but it is not
implemented in mlx5_ib.
This commit adds SQD2RTS command to the modify QP in mlx5_ib to support
the missing feature. The feature is required by the signature pipelining
API that will be added to rdma-core.

added pm_runtime_resume_and_get() in order to automatically handle
dev->power.usage_count decrement on errors.
Use the new API, in order to cleanup the error check logic.
As a bonus, pm_runtime_resume_and_get() always return 0 on success.
So, the code can be simplified.

The Bay Trail Glavey TM800A550L tablet, which ships with Android installed
from the factory, uses a GT912 touchscreen controller which needs to have
its firmware uploaded by the OS to work (this is a first for a x86 based
device with a Goodix touchscreen controller).
Add a touchscreen_dmi entry for this which specifies the filenames
to use for the firmware and config files needed for this.
Note this matches on a GDIX1001 ACPI HID, while the original DSDT uses
a HID of GODX0911. For the touchscreen to work on these devices a DSDT
override is necessary to fix a missing IRQ and broken GPIO settings in
the ACPI-resources for the touchscreen. This override also changes the
HID to the standard GDIX1001 id typically used for Goodix touchscreens.
The DSDT override is available here:

Teclast X89 tablets come in 2 versions, with Windows pre-installed and with
Android pre-installed. These 2 versions have different DMI strings.
Add a match for the DMI strings used by the Android version BIOS.
Note the Android version BIOS has a bug in the DSDT where no IRQ is
provided, so for the touchscreen to work a DSDT override fixing this
is necessary as well.
