[PATCH v4 01/12] mfd: da9063: Fix failpath in core

[PATCH v4 01/12] mfd: da9063: Fix failpath in core

[Marek Vasut]

In case mfd_add_devices() fails, da9063_irq_exit() is not called to
undo the IRQchip setup done by da9063_irq_init(). Fix this by adding
the missing fail path.

DA9063_IRQ_BASE_OFFSET is now unused, so please remove it
(before someone starts using it, and makes it non-zero ;-)

[PATCH v4 05/12] mfd: da9063: Rename PMIC_DA9063 to PMIC_CHIP_ID_DA9063

[Marek Vasut]

The PMIC_DA9063 is a complete misnomer, it denotes the value of the
DA9063 chip ID register, so rename it as such. It is also the value
of chip ID register of DA9063L though, so drop the enum as all the
DA9063 "models" share the same chip ID and thus the distinction will
have to be made using DT or otherwise.

[PATCH v4 06/12] mfd: da9063: Replace model with type

[Marek Vasut]

The model number stored in the struct da9063 is the same for all
variants of the da9063 since it is the chip ID, which is always
the same. Replace that with a separate identifier instead, which
allows us to discern the DA9063 variants by setting the type
based on either DT match or otherwise.

[PATCH v4 07/12] mfd: da9063: Add DA9063L type

[Marek Vasut]

Add type for DA9063L, which is a reduced variant of the DA9063
without RTC block and with less regulators.

[PATCH v4 08/12] mfd: da9063: Add custom regmap for DA9063L

[Marek Vasut]

The DA9063L does not have an RTC. Add custom regmap for DA9063L to
prevent access into that register block.

[PATCH v4 09/12] mfd: da9063: Add custom IRQ map for DA9063L

[Marek Vasut]

The DA9063L does not have an RTC. Add custom IRQ map for DA9063L to
ignore the Alarm and Tick IRQs from the PMIC.

[PATCH v4 10/12] mfd: da9063: Register RTC only on DA9063L

[Marek Vasut]

The DA9063L does not contain RTC block, unlike the full DA9063.
Split the RTC block into separate mfd cell and register it only
on DA9063.

Still not a fan of multi-line single entries, but seeing as it was
already multi-line and you are just moving it, I'll let it go.

[PATCH v4 11/12] regulator: da9063: Handle less LDOs on DA9063L

[Marek Vasut]

Move the LDOs present only on DA9063 at the end of the list, so that
the DA9063L can simply indicate less LDOs and still share the list of
regulators with DA9063.

[PATCH v4 12/12] mfd: da9063: Add DA9063L support

[Marek Vasut]

Add support for DA9063L, which is a reduced variant of the DA9063
with less regulators and without RTC.
