Krzysztof Kozlowski aad6c588bd mfd: lp87565: Fix Wvoid-pointer-to-enum-cast warning
'dev_type' is an enum, thus cast of pointer on 64-bit compile test with
W=1 causes:

  lp87565.c:95:23: error: cast to smaller integer type 'enum lp87565_device_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

Uwe Kleine-König 9816d85923 mfd: Switch i2c drivers back to use .probe()
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

Uwe Kleine-König 7ec69cc2aa mfd: lp87565: Convert to i2c's .probe_new()
The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

Alexander A. Klimov 4f4ed4543e mfd: Replace HTTP links with HTTPS ones
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.

Keerthy 1e3496000c mfd: Add LP87565 PMIC support
The LP87565 chip is a power management IC for Portable Navigation Systems
and Tablet Computing devices. It contains the following components:

        - Configurable Bucks(Single and multi-phase).
        - Configurable General Purpose Output Signals (GPO).

The LP87565-Q1 variant device uses two 2-phase outputs configuration,
Buck0 is master for Buck0/1 output and Buck2 is master for Buck2/3
output.
