The host makes direct calls into phy using ufs_qcom_phy_*()
APIs. These APIs are only defined for 20nm qcom-ufs-qmp phy
which is not being used by any architecture as yet. Future
architectures too are not going to use 20nm ufs phy.
So remove these ufs_qcom_phy_*() calls from host to let further
change declare the 20nm phy as broken.
Also remove couple of stale enum defines for ufs phy.

The rk3188 also supports bringing the uart2 out through
the usb dm+dp pins, so add the necessary setup for it.
rk3066 does not seem to support usb-uart functionality and this
particular phy was only used on older Rockchip socs, so this leaves
room for a bit of cleanup as well, as there most likely won't be new

When runtime is not enabled, pm_runtime_get_sync() returns -EACCESS,
the counter will be incremented but the resume callback not called,
so enumeration and charging will not start properly.
To avoid that happen, disable irq on suspend and recheck on resume.
Practically this happens when the device is woken up from suspend by
plugging in usb.

Since All R-Car Gen3 SoCs have dedicated otg pins actually but
some boards don't use the otg pins (e.g. R-Car D3 Draak and R-Car E3
Ebisu), the driver should not choose SoC model base by using
rcar_gen3_phy_usb2_match_table's data. So, this patch checks a
"renesas,no-otg-pins" property to set the "uses_otg_pins".
Note that since r8a77995-draak.dts and r8a77990-ebisu.dts don't have
'dr_mode = "otg";' for now, if we apply this patch, no behavior
changes (the value of "uses_otg_pins" is false).

After the commit 8b1087fa3a ("phy: qcom-qmp: Fix dts bindings to
reflect reality") landed there was some review feedback that 'reg'
should have been documented differently. Fix it as per review
feedback.
As per that feedback:
- Subject should have been 'dt-bindings: phy:' which this patch now
has.
- We should leave no ambiguity in the ordering of 'reg' ranges even if
'reg-names' are also specified.
- Normally using reg-names is discouraged unless there's a strong
reason it's needed (like if there are optional ranges). In this
case reg-names wasn't needed but the driver already landed relying
on reg-names so we'll just document it and move on.

"As it stands, memory_failure() gets thoroughly confused by dev_pagemap
backed mappings. The recovery code has specific enabling for several
possible page states and needs new enabling to handle poison in dax
mappings.
In order to support reliable reverse mapping of user space addresses:
1/ Add new locking in the memory_failure() rmap path to prevent races
that would typically be handled by the page lock.
2/ Since dev_pagemap pages are hidden from the page allocator and the
"compound page" accounting machinery, add a mechanism to determine
the size of the mapping that encompasses a given poisoned pfn.
3/ Given pmem errors can be repaired, change the speculatively
accessed poison protection, mce_unmap_kpfn(), to be reversible and
otherwise allow ongoing access from the kernel.
A side effect of this enabling is that MADV_HWPOISON becomes usable
for dax mappings, however the primary motivation is to allow the
system to survive userspace consumption of hardware-poison via dax.
Specifically the current behavior is:
mce: Uncorrected hardware memory error in user-access at af34214200
{1}[Hardware Error]: It has been corrected by h/w and requires no further action
mce: [Hardware Error]: Machine check events logged
