Devicetree updates for v6.13:

Browse Source 
Bindings:
 
 - Enable dtc "interrupt_provider" warnings for binding examples.
   Fix the warnings in fsl,mu-msi and ti,sci-inta due to this.
 
 - Convert zii,rave-sp-wdt, zii,rave-sp-pwrbutton,  and
   altr,fpga-passive-serial to DT schema format
 
 - Add some documentation on the different forms of YAML text blocks
   which are a constant source of review comments
 
 - Fix some schema errors in constraints for arrays
 
 - Add compatibles for qcom,sar2130p-pdc and onnn,adt7462
 
 DT core:
 
 - Allow overlay kunit tests to run CONFIG_OF_OVERLAY=n
 
 - Add some warnings on deprecated address handling
 
 - Rework early_init_dt_scan() so the arch can pass in the phys address
   of the DTB as __pa() is not always valid to use. This fixes a warning
   for arm64 with kexec.
 
 - Add and use some new DT graph iterators for iterating over ports and
   endpoints
 
 - Rework reserved-memory handling to be sized dynamically for fixed
   regions
 
 - Optimize of_modalias() to avoid a strlen() call
 
 - Constify struct device_node and property pointers where ever possible

Altera Passive Serial SPI FPGA Manager
Altera FPGAs support a method of loading the bitstream over what is
referred to as "passive serial".
The passive serial link is not technically SPI, and might require extra
circuits in order to play nicely with other SPI slaves on the same bus.
See https://www.altera.com/literature/hb/cyc/cyc_c51013.pdf
Required properties:
- compatible: Must be one of the following:
"altr,fpga-passive-serial",
"altr,fpga-arria10-passive-serial"
- reg: SPI chip select of the FPGA
- nconfig-gpios: config pin (referred to as nCONFIG in the manual)
- nstat-gpios: status pin (referred to as nSTATUS in the manual)
Optional properties:
- confd-gpios: confd pin (referred to as CONF_DONE in the manual)
Example:
fpga: fpga@0 {
compatible = "altr,fpga-passive-serial";
spi-max-frequency = <20000000>;
reg = <0>;
nconfig-gpios = <&gpio4 9 GPIO_ACTIVE_LOW>;
nstat-gpios = <&gpio4 11 GPIO_ACTIVE_LOW>;
confd-gpios = <&gpio4 12 GPIO_ACTIVE_LOW>;

or device does, standards the device conforms to, and links to datasheets for
more information.
The YAML format has several options for defining the formatting of the text
block. The options are controlled with indicator characters following the key
(e.g. "description: \|"). The minimum formatting needed for a block should be
used. The formatting controls can not only affect whether the YAML can be
parsed correctly, but are important when the text blocks are rendered to
another form. The options are as follows.
The default without any indicators is flowed, plain scalar style where single
line breaks and leading whitespace are stripped. Paragraphs are delimited by
blank lines (i.e. double line break). This style cannot contain ": " in it as
it will be interpretted as a key. Any " #" sequence will be interpretted as
a comment. There's other restrictions on characters as well. Most
restrictions are on what the first character can be.
The second style is folded which is indicated by ">" character. In addition
to maintaining line breaks on double line breaks, the folded style also
maintains leading whitespace beyond indentation of the first line. The line
breaks on indented lines are also maintained.
The third style is literal which is indicated by "\|" character. The literal
style maintains all line breaks and whitespace (beyond indentation of the
first line).
The above is not a complete description of YAML text blocks. More details on
multi-line YAML text blocks can be found online:
