Alexander A. Klimov 3593cd5396 Replace HTTP links with HTTPS ones: drivers/iio
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 both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

Andrew F. Davis b36e825764 iio: health/afe440x: Use regmap fields
These drivers can use regmap fields to access fields in registers, this
allows us to remove some macros/defines and simplify code, do this here.

Andrew F. Davis 24b9dea764 iio: health/afe440x: Remove channel names
These AFEs have 4 ADC mesuring stages (called LED2, ALED2, LED1, and
ALED1 in the datasheet), we map these as channels, these stages can serve
different purposes depending on the application. For instance the AFE4404
has an additional LED (LED3), this LED can be timed to be active during
stage 2 (or anystage, but the datasheet describes this case and the name
of the stage reflects this use). This ability is used further in upcoming
parts that tie the front-end gain and the LED timings together. For these
reasons we remove explicit naming the channels.

Without channel names it is best that the index numbers are in order to
match the stage number, reorder the channel numbers.

Andrew F. Davis 9d3d9a57e4 iio: health/afe440x: Fix scan_index assignment
The LED channels are not scannable and so scan_index should
be negative, fix this here.

Andrew F. Davis 81f517270d iio: health/afe440x: Always use separate gain values
Locking the two gain stages to the same setting adds no value for us,
so initialize them as unlocked and remove the sysfs for unlocking them.
This also allows us to greatly simplify showing and setting the gain
registers.

Andrew F. Davis 87aec56e27 iio: health: Add driver for the TI AFE4404 heart monitor
Add driver for the TI AFE4404 heart rate monitor and pulse oximeter.
This device detects reflected LED light fluctuations and presents an ADC
value to the user space for further signal processing.
