Even if a board doesn't have otg pins connection, this hardware can
change the role by a register setting. So, this patch adds
"is_otg_channel" for it.

If uses_otg_pins is set to false, this driver 1) should disable otg

This patch changes a condition about dr_mode. If a device node has

set "is_otg_channel" to true. Also, this patch keeps the dr_mode

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 8b1087fa ("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.

Pull libnvdimm memory-failure update from Dave Jiang:
 "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
     {1}[Hardware Error]: event severity: corrected
     Memory failure: 0xaf34214: reserved kernel page still referenced by 1 users
     [..]
     Memory failure: 0xaf34214: recovery action for reserved kernel page: Failed
     mce: Memory error not recovered

  ...and with these changes:

     Injecting memory failure for pfn 0x20cb00 at process virtual address 0x7f763dd00000
     Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption
     Memory failure: 0x20cb00: recovery action for dax page: Recovered
