2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <trini@konsulko.com>
2016-03-15input: TWL6030 input support for power button, USB and chargerPaul Kocialkowski
This adds support for detecting a few inputs exported by the TWL6030. Currently-supported inputs are the power button, USB and charger presence. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2016-03-15power: twl6030: Power off supportPaul Kocialkowski
This adds support for powering off (the omap SoC) from the twl6030. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2016-03-15power: twl6030: Clear VUSB_IN_PMID bit on USB device setupPaul Kocialkowski
When booting from USB, the bootrom sets the VUSB_IN_PMID bit of the MISC2 register of the TWL6030. However, U-Boot sets the VUSB_IN_VSYS bit to enable VBUS input. As both bits are contradictory, enabling both disables the input, according to the TWL6030 TRM. Thus, we need to clear the VUSB_IN_PMID bit in case of an USB boot (which could just as well be a memory boot after USB timed out). Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2016-03-15power: twl6030: Configure VUSB voltage on USB device setupPaul Kocialkowski
This explicitly sets VUSB voltage to 3.3V when enabling USB. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2016-03-15power: twl6030: Device-index-specific MMC power initializationPaul Kocialkowski
Not every device has multiple MMC slots available, so it makes sense to enable only the required LDOs for the available slots. Generic code in omap_hsmmc will enable both VMMC and VAUX1, in doubt. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2016-03-15power: twl6030: Enable VAUX1 for eMMC power, depending on BOOT2 valuePaul Kocialkowski
This enables the VAUX1 supply, used for eMMC power in standard configurations. Its voltage is determined by the value of the BOOT2 pin of the TWL6030. Note that the TWL6030 might already have enabled this regulator at startup (depending on the value of the BOOT3 pin of the TWL6030), according to the TWL6030 datasheet.

2016-03-15power: twl6030: Some more explicit registers and values definitionsPaul Kocialkowski
This makes the twl6030 mmc and usb-related power registers and values definitions more explicit and clear and adds prefixes to them. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
2013-12-04ARMV7: OMAP4: Add twl6032 supportOleg Kosheliev
Added chip type detection and twl6032 support in the battery control and charge functions. Based on Balaji T K <balajitk@ti.com> patches for TI u-boot. Signed-off-by: Oleg Kosheliev <oleg.kosheliev@ti.com>
2013-12-04ARMV7: OMAP4: Add struct for twl603x dataOleg Kosheliev
The data struct is used to support different PMIC chip types. It contains the chip type and the data (e.g. registers addresses, adc multiplier) which is different for twl6030 and twl6032. Replaced some hardcoded values with the structure vars. Based on Balaji T K <balajitk@ti.com> patches for TI u-boot. Signed-off-by: Oleg Kosheliev <oleg.kosheliev@ti.com>

2013-05-10twl6030: move twl6030 register access functions to common header fileNishanth Menon
twl6030_i2c_[read|write]_u8 can be used else where to access multi-function device such as twl6030, so move the register access functions to the common twl6030.h header file. Signed-off-by: Nishanth Menon <nm@ti.com>
