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.

Only the desc field is really used, so use struct regulator_desc instead.
Then struct pbias_regulator_data can be removed.

Reference manuals of OMAP5x and DRA7x have been updated to reflect
the PBIAS regulator max-voltage as 3.3V instead of 3.0V, while OMAP3x
and OMAP4x are still quoting 3.0V. So, as of now, the pbias driver
needs to support both 3.0V and 3.3V IO voltage based on the max-voltage
supported by the PBIAS regulator.

Declare regulator_ops structure as const as it is only stored in the ops
field of a regulator_desc structure. This field is of type const, so
regulator_ops structures having this property can be made const too.

Add separate compatible strings for every platform and populate the
pbias register offset in the driver data.
This helps avoid depending on the dt for pbias register offset.
Also update the dt binding documentation for the new compatible
strings.

regulator_disable of pbias always writes '0' to the enable_reg.
However actual disable value of pbias regulator is not always '0'.
Fix it by populating the disable_val in pbias_reg_info for the
various platforms and assign it to the disable_val of
pbias regulator descriptor. This will be used by
regulator_disable_regmap while disabling pbias regulator.

"regulator: helpers: Modify helpers enabling multi-bit control",
we can set enable_val setting for device that use multiple bits for control
when using regmap enable/disable/bypass ops.

The is_enabled implementation is wrong in some cases:
e.g. for pbias_mmc_omap5: enable_mask is : BIT(27) | BIT(25) | BIT(26)
However, pbias_regulator_enable() only sets BIT(27) | BIT(26) bits.
So is_enabled callback will always return false in this case.
Fix the logic to compare the register value with info->enable rather than
info->enable_mask.

pbias register controls internal power supply to sd card i/o pads
in most OMAPs (OMAP2-5, DRA7).
Control bits for selecting voltage level and
enabling/disabling are in the same PBIAS register.
