This driver uses platform data to pass GPIO lines using the

of this platform data.
Any out-of-tree or coming users of this driver can easily be

Commit 9c80662a74 ("power: supply: axp288_charger: Add special handling
for HP Pavilion x2 10") added special handling for HP Pavilion x2 10
models which use the weird combination of a Type-C connector and the
non Type-C aware AXP288 PMIC.
This special handling was activated by a DMI match a the product-name
of "HP Pavilion x2 Detachable". Recently I've learned that there are
also older "HP Pavilion x2 Detachable" models with an AXP288 PMIC +
a micro-usb connector where we should not activate the special handling
for the Type-C connectors.
Extend the matching to also match on the DMI board-name and match on the
2 boards (one Bay Trail based one Cherry Trail based) of which we are
certain that they use the AXP288 + Type-C connector combination.
Note the DSDT code from these older (AXP288 + micro-USB) models contains
some AML code (which never runs under Linux) which reads the micro-USB
connector id-pin and if it is pulled to ground, which would normally mean
the port is in host mode!, then it sets the input-current-limit to 3A,
it seems HP is using the micro-USB port as a charging only connector
and identifies their own 3A capable charger though this hack which is a
major violation of the USB specs. Note HP also hardcodes a 2A limit
when the id-pin is not pulled to ground, which is also in violation
of the specs.
I've no intention to add support for HP's hack to support 3A charging
on these older models. By making the DMI matches for the Type-C equipped
models workaround more tighter, these older models will be treated just
like any other AXP288 + micro-USB equipped device and the input-current
limit will follow the BC 1.2 spec (using the defacto standard values
there where the BC 1.2 spec defines a range).

The probe routine acquires the reset GPIO using GPIOD_OUT_LOW. Directly
afterwards it calls acx565akm_detect(), which sets the GPIO value to
HIGH. If the bootloader initialized the GPIO to HIGH before the probe
routine was called, there is only a very short time period of a few
instructions where the reset signal is LOW. Exact time depends on
compiler optimizations, kernel configuration and alignment of the stars,
but I expect it to be always way less than 10us. There are no public
datasheets for the panel, but acx565akm_power_on() has a comment with
timings and reset period should be at least 10us. So this potentially
brings the panel into a half-reset state.
The result is, that panel may not work after boot and can get into a
working state by re-enabling it (e.g. by blanking + unblanking), since
that does a clean reset cycle. This bug has recently been hit by Ivaylo
Dimitrov, but there are some older reports which are probably the same
bug. At least Tony Lindgren, Peter Ujfalusi and Jarkko Nikula have
experienced it in 2017 describing the blank/unblank procedure as
possible workaround.
Note, that the bug really goes back in time. It has originally been
introduced in the predecessor of the omapfb driver in commit 3c45d05be3
("OMAPDSS: acx565akm panel: handle gpios in panel driver") in 2012.
That driver eventually got replaced by a newer one, which had the bug
from the beginning in commit 84192742d9 ("OMAPDSS: Add Sony ACX565AKM
panel driver") and still exists in fbdev world. That driver has later
been copied to omapdrm and then was used as a basis for this driver.
Last but not least the omapdrm specific driver has been removed in
commit 45f16c82db ("drm/omap: displays: Remove unused panel drivers").

In case of panels with low vertical back porch, the prefill bw
requirement will be high as we will have less time(vbp+pw) to
fetch and fill the hw latency buffers before start of first line
in active period.
For ex:
Say hw_latency_line_buffers = 24, and if blanking vbp+pw = 10
Here we need to fetch 24 lines of data in 10 line times.
This will increase the bw to the ratio of linebuffers to blanking.
DPU hw can also fetch data during vertical front porch provided
interface prefetch is enabled. Use vfp in the prefill calculation
as dpu driver enables prefetch if the blanking is not sufficient
to fill the latency lines.

Pull irq fixes from Thomas Gleixner:
"Two fixes for irqchip drivers:
- Save and restore the GICV3 ITS state unconditionally on
suspend/resume to handle firmware which fails to do so.
- Use the correct index into the fwspec parameters to read the irq
trigger type in the EXIU chip driver"

GPU targets with an MMU-500 attached have a slightly different process for
enabling system cache. Use the compatible string on the IOMMU phandle
to see if an MMU-500 is attached and modify the programming sequence
accordingly.

The last level system cache can be partitioned to 32 different
slices of which GPU has two slices preallocated. One slice is
used for caching GPU buffers and the other slice is used for
caching the GPU SMMU pagetables. This talks to the core system
cache driver to acquire the slice handles, configure the SCID's
to those slices and activates and deactivates the slices upon
GPU power collapse and restore.
Some support from the IOMMU driver is also needed to make use
of the system cache to set the right TCR attributes. GPU then
has the ability to override a few cacheability parameters which
it does to override write-allocate to write-no-allocate as the
GPU hardware does not benefit much from it.
DOMAIN_ATTR_IO_PGTABLE_CFG is another domain level attribute used
by the IOMMU driver for pagetable configuration which will be used
to set a quirk initially to set the right attributes to cache the
hardware pagetables into the system cache.
