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.

Description
|
|
-----------
|
|
|
|
This driver provides connects a NXP SC18IS602/603 I2C-bus to SPI bridge to the
|
|
kernel's SPI core subsystem.
|
|
|
|
The driver does not probe for supported chips, since the SI18IS602/603 does not
|
|
support Chip ID registers. You will have to instantiate the devices explicitly.
|
|
Please see Documentation/i2c/instantiating-devices.rst for details.
|

|
Usage Notes
|
|
-----------
|
|
|
|
This driver requires the I2C adapter driver to support raw I2C messages. I2C
|
|
adapter drivers which can only handle the SMBus protocol are not supported.
|
|
|
|
The maximum SPI message size supported by SC18IS602/603 is 200 bytes. Attempts
|
|
to initiate longer transfers will fail with -EINVAL. EEPROM read operations and
|
|
similar large accesses have to be split into multiple chunks of no more than
|
|
200 bytes per SPI message (128 bytes of data per message is recommended). This
|
|
means that programs such as "cp" or "od", which automatically use large block
|
|
sizes to access a device, can not be used directly to read data from EEPROM.
|
|
Programs such as dd, where the block size can be specified, should be used
|
|
instead.
