regulator: raa215300: Add build dependency with COMMON_CLK

The COMMON_CLK config is not enabled in some of the architectures.
This causes build issues. Fix these issues by adding build dependency.

2023-06-28T14:17:45+00:00

Regulator driver for both MAX77541 and MAX77540.
The MAX77541 is a high-efficiency step-down converter
with two 3A switching phases for single-cell Li+ battery
and 5VDC systems.

The MAX77540 is a high-efficiency step-down converter
with two 3A switching phases.

Add Renesas PMIC RAA215300 and built-in RTC

2023-06-24T00:57:59+00:00

Merge series from Biju Das :

This patch series aims to add support for Renesas PMIC RAA215300 and
built-in RTC found on this PMIC device.

The details of PMIC can be found here[1].

Renesas PMIC RAA215300 exposes two separate i2c devices, one for the main
device and another for rtc device.

regulator: Add Renesas PMIC RAA215300 driver

2023-06-23T15:29:00+00:00

The RAA215300 is a 9-channel PMIC that consists of
 * Internally compensated regulators
 * built-in Real Time Clock (RTC)
 * 32kHz crystal oscillator
 * coin cell battery charger

The RTC on RAA215300 is similar to the IP found in the ISL1208.
The existing driver for the ISL1208 works for this PMIC too,
however the RAA215300 exposes two devices via I2C, one for the RTC
IP, and one for everything else. The RTC IP has to be enabled
by the other I2C device, therefore this driver is necessary to get
the RTC to work.

The external oscillator bit is inverted on PMIC version 0x11.

Add PMIC RAA215300 driver for enabling RTC block and instantiating
RTC device based on PMIC version.

regulator: ltc3676: Use maple tree register cache

2023-06-19T11:59:45+00:00

The ltc3676 can only support single register read and write operations
so does not benefit from block writes. This means it gets no benefit from
using the rbtree register cache over the maple tree register cache so
convert it to use maple trees instead, it is more modern.

regulator: mt6358: Use linear voltage helpers for single range regulators

2023-06-14T13:25:48+00:00

Some of the regulators on the MT6358/MT6366 PMICs have just one linear
voltage range. These are the bulk regulators and VSRAM_* LDOs. Currently
they are modeled with one linear range, but also have their minimum,
maximum, and step voltage described.

Convert them to the linear voltage helpers. These helpers are a bit
simpler, and we can also drop the linear range definitions. Also reflow
the touched lines now that they are shorter.
