Message-ID: <20241026200213.1906375-1-csokas.bence@prolan.hu>

Subject: [PATCH v2] power: ip5xxx_power: Use regmap_field API
The IP53xx series [1] has a much different register
layout than the 51xx/52xx [2] currently supported
by this driver. To accommodate supporting the former,
refactor the code to use the flexible regmap_field API.

[2] https://www.windworkshop.cn/wp-content/uploads/2022/04/IP5209-IP5109-IP5207-IP5108-I2C-registers.pdf
Signed-off-by: Csókás, Bence <csokas.bence@...lan.hu>

Notes:
Changes in v2:
* s/&ip5xxx->regs/ip5xxx->regs/g
* and then undo it for the ADC regs...
* s/;/,/ on `ip51xx_fields`
* and some other typos...
