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. Signed-off-by: Tom Rini

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. Signed-off-by: Chen-Yu Tsai Reviewed-by: Hans de Goede Signed-off-by: Hans de Goede

sunxi: Implement poweroff support for axp221 pmic

Adds poweroff support for axp221 pmic. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

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. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

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. Signed-off-by: Hans de Goede Reviewed-by: Simon Glass Acked-by: Ian Campbell

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. Signed-off-by: Hans de Goede Reviewed-by: Simon Glass Acked-by: Ian Campbell

sunxi: axp: Change axp_gpio_foo prototypes to match gpio uclass ops

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

Change the axp_gpio_foo function prototypes to match the gpio uclass op prototypes, this is a preparation patch for moving the axp gpio code to a separate driver-model gpio driver. Note that the ugly calls with a NULL udev pointer in drivers/gpio/sunxi_gpio.c this adds are removed in a later patch. Signed-off-by: Hans de Goede Reviewed-by: Simon Glass Acked-by: Ian Campbell

power: axp221: Virtual VBUS detect and enable GPIOs to replace separate logic

2015-04-15T14:17:17+00:00

This converts the VBUS detection and enable logic to GPIO instead of separate axp functions and checks that have to be used aside usual GPIO functions. Signed-off-by: Paul Kocialkowski Acked-by: Hans de Goede Signed-off-by: Hans de Goede

sunxi: axp221: Add VBUS detection support

2015-03-10T14:20:25+00:00

Some of the AXP PMICs support VBUS detection, i.e. checking whether VBUS power input is available and usable (supplied by an external source). A few boards use this instead of a separate GPIO to detect VBUS on USB OTG. Signed-off-by: Chen-Yu Tsai Acked-by: Hans de Goede Signed-off-by: Hans de Goede

sunxi: rsb: Move rsb_set_device_mode() call to rsb_init()

2015-02-02T12:55:14+00:00

It turns out that the device_mode_data is rsb specific, rather then slave specific, so integrate the rsb_set_device_mode() call into rsb_init(). Signed-off-by: Hans de Goede Acked-by: Ian Campbell
