2020-03-01rtc: m41t62: add compatible for m41st87Marek Vasut
This adds a compatible string for m41st87. This ensures that this driver can be used for m41st87. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com> Cc: Stefan Roese <sr@denx.de> Reviewed-by: Stefan Roese <sr@denx.de>
2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-07-09rtc: pcf2127: Fixed bug with rtc settings and getting error timeChuanhua Han
The previous pcf2127 RTC chip could not read and set the correct time. When reading the data of internal registers, the read address was the value of register plus 1. This is because this chip requires the host to send a stop signal after setting the register address and before reading the register data. This patch sets the register address using dm_i2c_write and reads the register data using the original dm_i2c_xfer in order to generate a stop signal after the register address is set, and fixes the bug of the original read and write time.

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>
