mfd: cs5535: Don't build on UML

2023-03-10T08:28:46+00:00

[ Upstream commit 5ec32a3e4053c1a726b45381d56aa9e39eaf3911 ]

The cs5535-mfd driver uses CPU-specific data that is not available
for ARCH=um builds, so don't allow it to be built for UML.

Prevents these build errors:

mfd: Drop obsolete dependencies on COMPILE_TEST

2022-12-08T13:15:46+00:00

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

As a minor optimization, this also lets us drop of_match_ptr(), as we
now know what it will resolve to, we might as well save cpp some work.

mfd: tps65219: Add driver for TI TPS65219 PMIC

2022-12-07T13:28:15+00:00

The TPS65219 is a power management IC PMIC designed to supply a wide
range of SoCs in both portable and stationary applications. Any SoC can
control TPS65219 over a standard I2C interface.

It contains the following components:
- Regulators.
- Over Temperature warning and Shut down.
- GPIOs
- Multi Function Pins (MFP)
- power-button

This patch adds support for tps65219 PMIC. At this time only
the functionalities listed below are made available:

- Regulators probe and functionalities
- warm and cold reset support
- SW shutdown support
- Regulator warnings via IRQs
- Power-button via IRQ

mfd: bd957x: Fix Kconfig dependency on REGMAP_IRQ

2022-12-07T13:28:15+00:00

The BD957x driver uses REGMAP_IRQ but does not 'select' to depend on
it. This can cause build failures.  Select REGMAP_IRQ for BD957X.

mfd: intel_soc_pmic: Allow COMPILE_TEST or I2C_DESIGNWARE_PLATFORM

2022-12-07T13:28:10+00:00

Linus expressed a desire to have intel_soc_pmic_crc.o (INTEL_SOC_PMIC,
for Crystal Cove) be built on an "allmodconfig" build, when
I2C_DESIGNWARE_PLATFORM=m, to enhance build test coverage.

The PMIC driver won't work in this case since it requires
I2C_DESIGNWARE_PLATFORM=y to operate properly, but adding
"|| COMPILE_TEST" does improve the build test coverage.
