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
|
|
-----------
|
|
|
|
- LTC2974 and LTC2975 are quad digital power supply managers.
|
|
- LTC2978 is an octal power supply monitor.
|
|
- LTC2977 is a pin compatible replacement for LTC2978.
|
|
- LTC2980 is a 16-channel Power System Manager, consisting of two LTC2977
|
|
- in a single die. The chip is instantiated and reported as two separate chips
|
|
- on two different I2C bus addresses.
|
|
- LTC3880, LTC3882, LTC3886, and LTC3887 are dual output poly-phase step-down
|
|
- DC/DC controllers.
|
|
- LTC3883 is a single phase step-down DC/DC controller.
|
|
- LTM2987 is a 16-channel Power System Manager with two LTC2977 plus
|
|
- additional components on a single die. The chip is instantiated and reported
|
|
- as two separate chips on two different I2C bus addresses.
|
|
- LTM4675 is a dual 9A or single 18A μModule regulator
|
|
- LTM4676 is a dual 13A or single 26A uModule regulator.
|
|
- LTM4686 is a dual 10A or single 20A uModule regulator.
|

Usage Notes
|
|
-----------
|
|
|
|
This driver does not probe for PMBus devices. You will have to instantiate
|
|
devices explicitly.
|
|
|
|
Example: the following commands will load the driver for an LTC2978 at address
|
|
0x60 on I2C bus #1::
|
|
|
|
# modprobe ltc2978
|
|
# echo ltc2978 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
