gpio: axp: Remove virtual VBUS enable GPIO

2025-04-28T18:45:44+00:00

Now that this functionality is modeled using the device tree and
regulator uclass, the named GPIO is not referenced anywhere. Remove
it, along with the rest of the support for AXP virtual GPIOs.

pmic: axp: define ALDO_IN startup bit

2022-01-30T01:25:00+00:00

Most AXP PMICs feature a "startup source" register, which keeps
information about how the PMIC started operation. Bit 0 in there means
it has been started by "plugging in the power cable".

Define a symbol in each PMIC's header file to be able to use that
register and bit later on.

include: axp_pmic: Include headers for all variants

2021-10-25T13:50:42+00:00

A single DM-based driver should be able to support some feature for
several PMIC variants where the interface is the same. For example,
all PMIC variants use the same register bit to trigger poweroff.

However, currently only definitions for a single PMIC are available at
a time. This requires drivers to use #ifdefs and different indentifiers
for each variant they support.

Let's simplify this by making register definitions for all variants
available from the header. Then no preprocessor conditions are needed;
the driver can use the register definition from any variant that
supports the relevant feature.

An exception is the GPIO-related definitions, which do not use unique
identifiers. So for now, keep them like before. They will be cleaned up
along with the GPIO driver.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

sunxi: axp: Generalize register macros for VBUS drive GPIO

2016-03-31T15:03:52+00:00

VBUS drive is supported on AXP221 and later PMICs. Rework the macros
so we can support this on later PMICs without too much work.

sunxi: power: Unify axp pmic function names

2015-10-20T16:40:27+00:00

Stop prefixing the axp functions for setting voltages, etc. with the
model number, there ever is only one pmic driver built into u-boot,
this allows simplifying the callers.

sunxi: axp: Move axp gpio code to a separate axpi-gpio driver

2015-05-04T14:51:53+00:00

Move the axp-gpio code out of the drivers/power/axp*.c code, and into
a new separate axpi-gpio driver.

This change drops supports for the gpio3 pin on the axp209, as that requires
special handling, and no boards are using it.

Besides cleaning things up by moving the code to a separate driver, as
a bonus this change also adds support for the (non vusb) gpio pins on the
axp221 and the gpio pins on the axp152.

The new axp-gpio driver gets its own Kconfig option, and is only enabled
on boards which need it. Besides that it only gets enabled in the regular
u-boot build and not for the SPL as we never need it in the SPL.

sunxi: axp: Move axp pmic register helpers to a separate file

2015-05-04T14:51:53+00:00

Move the register helpers used to access the registers via p2wi resp.
rsb bus on the otherwise identical axp221 and axp223 pmics to a separate
file, so that they can be used by the upcoming standalone axp gpio driver
too.
