f516fb704d dt-bindings: Whitespace clean-ups in schema files
Clean-up incorrect indentation, extra spaces, long lines, and missing
EOF newline in schema files. Most of the clean-ups are for list
indentation which should always be 2 spaces more than the preceding
keyword.

Found with yamllint (which I plan to integrate into the checks).

441977979a Merge tag 'devicetree-for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring:

 - Improve device links cycle detection and breaking. Add more bindings
   for device link dependencies.

 - Refactor parsing 'no-map' in __reserved_mem_alloc_size()

 - Improve DT unittest 'ranges' and 'dma-ranges' test case to check
   differing cell sizes

 - Various http to https link conversions

 - Add a schema check to prevent 'syscon' from being used by itself
   without a more specific compatible

 - A bunch more DT binding conversions to schema

7ac9bbf6ab dt-bindings: lpspi: New property in document DT bindings for LPSPI
Add "fsl,spi-only-use-cs1-sel" to fit i.MX8DXL-EVK.
Spi common code does not support use of CS signals discontinuously.
It only uses CS1 without using CS0. So, add this property to re-config
chipselect value.

3ea4eac3e2 SPI SUBSYSTEM: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

164c05f03f spi: Convert DW SPI binding to DT schema
Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces two DW SPI legacy
bare text bindings with YAML file. As before the bindings file states
that the corresponding dts node is supposed to be compatible either
with generic DW APB SSI controller or with Microsemi/Amazon/Renesas/Intel
vendors-specific controllers, to have registers, interrupts and clocks
properties. Though in case of Microsemi version of the controller
there must be two registers resources specified. Properties like
clock-names, reg-io-width, cs-gpio, num-cs, DMA and slave device
sub-nodes are optional.

fba5618451 dt-bindings: Fix incorrect 'reg' property sizes
The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.

The easiest fix in most cases is to change the 'reg' property to for 1 cell
address and size. In some cases with child devices having 2 cells, that
doesn't make sense so a bus node is needed.

3812a081d2 spi: dw-apb-ssi: Add compatible string for DesignWare DWC_ssi
This patch adds compatible string "snps,dwc-ssi-1.01a" to the above DT
binding document, to provide support for DesignWare DWC_ssi IP [1].

Current driver supports DW_apb_ssi IP [2].

3d21a46093 dt-bindings: Remove cases of 'allOf' containing a '$ref'
json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

9f60a65bc5 dt-bindings: Clean-up schema indentation formatting
Fix various inconsistencies in schema indentation. Most of these are
list indentation which should be 2 spaces more than the start of the
enclosing keyword. This doesn't matter functionally, but affects running
scripts which do transforms on the schema files.

  addition to the DT description

  A moderate number of new SoCs and machines are added, here is a full
  list:

   - Two new Qualcomm SoCs with their evaluation boards: Snapdragon 865
     (SM8250) is the current high-end phone chip, and IPQ6018 is a new
     WiFi-6 router chip.

   - Mediatek MT8516 application processor SoC for voice assistants,
     along with the "pumpkin" development board

     evaluation board.

   - Kontron "sl28" board family based on NXP LS1028A

   - Eleven variations of the new i.MX6 TechNexion Pico board, combining
     the "dwarf", "hobbit", "nymph" and "pi" baseboards with i.MX6/i.MX7
     SoM carriers

   - Three additional variants of the Toradex Colibri board family, all
     based on versions of the NXP i.MX7.

   - The Pinebook Pro laptop based on Rockchip RK3399

     on the ST-Ericsson u8500 platform

The descriptions for the spi-rx-bus-width and spi-tx-bus-width
properties refer to "MISO" and "MOSI", which are not explained in the
document.  While these abbreviations are fairly common when talking
about SPI, and thus may not need an explanation, they are not entirely
correct in this context, as the SPI controller may be used in slave mode
instead of master mode.

Fix this by replacing them by "read transfers" resp. "write transfers",
like is done for the spi-rx-delay-us and spi-tx-delay-us properties.

Currently, the DT bindings for an SPI controller specify that
"#address-cells" must be fixed to one.  However, that applies to an SPI
controller in master mode only.  When running in SPI slave mode,
"#address-cells" should not be specified.

Fix this making "#address-cells" mutually-exclusive with "spi-slave".

spi-mtk-nor is a driver to replace mtk-quadspi and they have almost
the same device-tree bindings. Reuse this binding documentation and
convert it for new driver:

1. "Mediatek SoCs" -> "Mediatek ARM SoCs" because MTK MIPS SoCs
   use different controllers.
2. document "interrupts" as a required property because it's
   available on all SoCs with this controller and new driver takes
   advantages of it. It's implemented as optional only to maintain
   backward compatibility.
3. add a dummy interrupt binding in example.
