2019-04-21stm32mp1: add stusb1600 support for DK1 and DK2 boardPatrick Delaunay
The DK1 and DK2 boards use the USB Type-C controller STUSB1600. This patch updates: - the device tree to add the I2C node in the DT - the board stm32mp1 to probe this I2C device and use this controller to check cable detection. - the DWC2 driver to support a new dt property "u-boot,force-b-session-valid" which forces B session and device mode; it is a workaround because the VBUS sensing and ID detection isn't available with stusb1600.

2019-04-12Board: stm32mp1: Add supply current boot informationPatrice Chotard
For DK1/DK2 boards, check if power supply provides enough current to allow the board to boot correctly. ADC@0 channel 18 and 19 are connected to USB type-C CC1 and CC2 signals. The table below shows the behavior for different range of CC1 or CC2: range | power supply | red led | console message (Volts) | (Amps) | blinks | --------------|--------------|---------|----------------------------------- [2.10 - 1.23[ | 3 | NO | NO [1.23 - 0.66[ | 1.5 | 3 times | WARNING 1.5A power supply detected [0.66 - 0] | 0.5 | 2 times | WARNING 500mA power supply detected If detected current is < 3A, red led is kept ON after blinking.

2018-05-07SPDX: Convert all of our multiple 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 multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>
