b23c4771ff A fair amount of stuff this time around, dominated by yet another massive
set from Mauro toward the completion of the RST conversion.  I *really*
 hope we are getting close to the end of this.  Meanwhile, those patches
 reach pretty far afield to update document references around the tree;
 there should be no actual code changes there.  There will be, alas, more of
 the usual trivial merge conflicts.
 
 Beyond that we have more translations, improvements to the sphinx
 scripting, a number of additions to the sysctl documentation, and lots of
 fixes.

e24e03aa00 arm64: docs: Mandate that the I-cache doesn't hold stale kernel text
Although we require that the loaded kernel Image has been cleaned to the
PoC, we neglect to spell out the state of the I-cache. Although this
should be reasonably obvious, it doesn't hurt to be explicit.

Require that the I-cache doesn't hold any stale entries for the kernel
Image at boot.

877a37d31e docs: arm64: booting.rst: get rid of some warnings
Get rid of those warnings:

    Documentation/arm64/booting.rst:253: WARNING: Unexpected indentation.
    Documentation/arm64/booting.rst:259: WARNING: Block quote ends without a blank line; unexpected unindent.

By adding an extra blank lines where needed.

While here, use list markups on some places, as otherwise Sphinx
will consider the next lines as continuation of the privious ones.

7e3a57fa6c arm64: Document ICC_CTLR_EL3.PMHE setting requirements
It goes without saying, but better saying it: the kernel expects
ICC_CTLR_EL3.PMHE to have the same value across all CPUs, and
for that setting not to change during the lifetime of the kernel.

   Various examples are fixed due to that.
 
 - Sync dtc with upstream version v1.5.0-30-g702c1b6c0e73
 
 - Initial schemas for networking bindings. This includes ethernet, phy
   and mdio common bindings with several Allwinner and stmmac converted
   to the schema.
 
 - Conversion of more Arm top-level SoC/board bindings to DT schema
 
 - Conversion of PSCI binding to DT schema
 
 - Rework Arm CPU schema to coexist with other CPU schemas
 
 - Add a bunch of missing vendor prefixes and new ones for SoChip,
   Sipeed, Kontron, B&R Industrial Automation GmbH, and Espressif
 
 - Add Mediatek UART RX wakeup support to binding
 
 - Add reset to ST UART binding
 
 - Remove some Linuxisms from the endianness common-properties.txt

b693d0b372 docs: arm64: convert docs to ReST and rename to .rst
The documentation is in a format that is very close to ReST format.

The conversion is actually:
  - add blank lines in order to identify paragraphs;
  - fixing tables markups;
  - adding some lists markups;
  - marking literal blocks;
  - adjust some title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
