2018-11-30rtc: rv3029: update to support DM and sync with Linux 4.17Philipp Tomsich
The "Flamingo" carrier-board for the RK3399-Q7 has a RV3029 populated and the application will use the off-module RV3029 RTC including the battery backed SRAM. To support this use case, this commit includes the following changes: * updates the rv3029 driver to use DM * implements the read8/write8 operations This syncs the implementation with the Linux code (based on 4.17), porting the trickle-charger support from there (with improvements to avoid unnecessary EEPROM updates) and adheres to the Linux DTS binding.

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>
