Subject: [PATCH v2 0/2] Add support for ADP5055 triple buck regulator.

Introduce a regulator driver support for ADP5055. The device combines 3
high performance buck regulators in a 43-termminal land grid array
package. The device enables direct connection to high input voltages up
to 18V with no preregulator. Channel 1 and 2 deliver a programmable
output current of 3.5A or 7.5A or provide a single output with up to 14A
in parallel operation. Channel 3 has a programmable output current of
1.5A or 3A.

Changes in v2:
- Kconfig - fixed indention problem, occured due to using spaces rather tabs
- adp5055-regulator.c
  - Turned initial comment block into c++ style, using // per line
  - Merged the similar read/write ranges variable called access_ranges_table
  - Set max_register value correctly to 0xE0 instead of 0xFF
  - Fixed issue where ndescs was an error code. replaced with -EINVAL
  - Enable/disable ops functions, now use helpers like regulator_enable_regmap
  - Added config.ena_gpiod for the regulator config  
  - Used of_parse_cb to do per regulator properties, new function added
  - Migrated some yaml properties to the core regulator function
-adi,adp5055-regulator.yaml
  - Moved property power_saving_mode to set/get mode under 'IDLE' mode
  - Moved property output-discharge-func to core func set_active_discharge
  - Moved property enable-delay-us to core function set_ramp_delay.
  - Removed property disable-delay-us, as suggested to not worry about
  - adjusted sample device tree to match changes due to use of of_parse_cb
- Link to v1: https://lore.kernel.org/r/20250225-upstream-adp5055-v1-0-a5a7f8e46986@analog.com
