This patchset series adds support for the TPS6594x PMIC along with
initial support for its RTC + GPIO interface, and poweroff sequence.

Additionally, add usage of the PMIC for the various Jacintor platforms
devicetree's.

Changes from v1:
* Corrected devicetree documentation issues found with dt-schema
* Changed MFD references to PMIC reflecting the more valid use of driver
* Cleaning up variable naming and ordering within functions
* Adding gpio + regulator cells for upcoming driver support
* Switching from .probe to .probe_new API
* Revising comments within drivers to be more concise
* Adding device tree nodes for j721s2 and j721e platforms

Changes from v2:
* Adding gpio-tps6594x driver support
* Enabling gpio cell in MFD driver

Changes from v3:
* Refactoring gpio driver to use regmap gpio helpers
* Changing rtc driver to use more of device resource management
* Minor code changes related to error messages that aren't useful
being dropped
* Dropped wildcard in device-tree compatible, and i2c device id
* Dropped device tree changes from the series; since these should
be in their own series later
