Subject: [PATCH v2 07/15] mfd: bd71828: Support ROHM BD72720
The ROHM BD72720 is a power management IC which continues the BD71828
family of PMICs. Similarly to the BD71815 and BD71828, the BD72720
integrates regulators, charger, RTC, clock gate and GPIOs.
The main difference to the earlier PMICs is that the BD72720 has two
different I2C slave addresses. In addition to the registers behind the
'main I2C address', most of the charger (and to some extent LED) control
is done via registers behind a 'secondary I2C slave address', 0x4c.

For some reason the gmail SMTP server refused from sending this (several
times). If anyone receives this more than once - I am sorry! In order to
get this through I now send this only to the lists, dropping all the
direct CCs...
Seems I need to find alternate SMTP server for my patches :(
Revision history:
RFCv1 => v2: (Mostly addressed comments from Lee and Andreas)
- Use stacked regmaps to avoid platform data and the tango with
multiple regmaps in the power-supply driver
- Use regmap_reg_range()
- make it clear bd72720_irq_type_base is an array
- tab-out definitions in the bd72720 header
- minor styling
Note: This patch depends on the series: "power: supply: add charger for
BD71828" by Andreas:
https://lore.kernel.org/all/20250918-bd71828-charger-v5-0-851164839c28@kemnade.info/
There are some new variants being planned. Most notably, the BD73900
should be almost identical to the BD72720 - for everything else except
the charger block.

+ * The BD72720 is an odd beast in that it contains two separate sets of

+ * a slave address 0x4b, which will be used as the "main" address for this
+ * device.
+ * Most of the charger related registers are located behind slave address 0x4c.
+ * It is tempting to push the dealing with the charger registers and the extra
+ * 0x4c device in power-supply driver - but perhaps it's better for the sake of
+ * the cleaner re-use to deal with setting up all of the regmaps here.
+ * Furthermore, the LED stuff may need access to both of these devices.
+ *
+ * Instead of providing one of the regmaps to sub-devices in MFD platform data,
+ * we create one more 'wrapper regmap' with custom read/write operations. These
+ * custom accessors will select which of the 'real' regmaps to use, based on
+ * the register address.
+ * The register addresses are 8-bit, so we add offset 0x100 to the addresses
+ * behind the secondary slave 0x4c. The 'wrapper' regmap can then detect the
+ * correct slave address based on the register address and call regmap_write()
+ * and regmap_read() using correct 'real' regmap. This way the registers of
+ * both of the slaves can be accessed using one 'wrapper' regmap.
+ *
+ * NOTE: The added offsets mean that the defined addresses for slave 0x4c must
+ * be used through the 'wrapper' regmap because the offset must be stripped
+ * from the register addresses. The 0x4b can be accessed both indirectly using
