power: pmic: axp: Implement poweroff via sysreset

2021-10-25T13:51:03+00:00

The AXP PMICs have the ability to power off the system. The existing
code for this is duplicated for each PMIC variant, and uses the legacy
non-DM "pmic_bus" interface. When SYSRESET is enabled, this can all be
replaced with a sysreset device using the DM_PMIC interface.

Since the trigger bit is the same on all PMIC variants, use the register
definitions from the oldest supported PMIC.

power: axp: Avoid do_poweroff conflict with sysreset

2021-10-25T13:50:54+00:00

The sysreset uclass has an option to provide the do_poweroff() function.
When that option is enabled, the AXP power drivers should not provide
their own definition.

For the AXP305, which is paired with 64-bit systems where TF-A provides
PSCI, there is another possible conflict with the PSCI firmware driver.
This driver can be enabled even if CONFIG_PSCI_RESET is disabled, so
make sure to use the right symbol in the condition.

The bulk of it is Samuel's DM_I2C rework, which removes the nasty I2C
deprecation warnings for most 32-bit boards. It also includes some
smaller refactorings that pave the way for more changes, mostly driven
by needing to support the Allwinner RISC-V SoC later on.

Board wise we gain support for the FriendlyARM NanoPi R1S H5 router
board and official Pinetab support.

Build-tested for all 160 sunxi boards, and boot tested on a A64, A20,
H3, H6, and H616 board. USB, SD card, eMMC, and Ethernet all work there
(where applicable).

power: pmic: Add a driver for X-Powers AXP PMICs

2021-10-12T08:41:57+00:00

These PMICs provide some combination of battery charger, fuel gauge,
GPIOs, regulators, and VBUS routing. These functions are represented
as child nodes in the device tree. Add the minimal driver needed to
probe these child devices and provide the DM_PMIC ops.

Enable the driver by default for SoCs that normally pair with a PMIC.

power: pmic: Consistently depend on SPL_DM_PMIC

2021-10-12T08:36:02+00:00

Now that there is a separate symbol to enable DM_PMIC in SPL, update the
the SPL-specific driver symbols to depend on this new option.

power: pmic: Consistently depend on DM_PMIC

2021-10-12T08:35:41+00:00

Kconfig symbols for two PMIC drivers (PMIC_AS3722 and DM_PMIC_MC34708)
were missing a dependency on DM_PMIC. To fix this inconsistency, and to
keep it from happening again, wrap the driver section with "if DM_PMIC"
instead of using a "depends on DM_PMIC" clause for each driver.

sunxi: Clean up inclusions of asm/arch/gpio.h

2021-10-11T09:46:44+00:00

As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various
files that include it.

Some files did not contain any GPIO code at all, so this header was
completely unused.

A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.

The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the
right header to include once the DM_GPIO migration is complete and
GPIO_EXTRA_HEADER is no longer needed.
