* rtc: stm32: manage 2 digit limitation on yearPatrick Delaunay2019-08-271-2/+7
| | | | | | | | | | | STM32 RTC manages only 2 digits for YEAR (Year tens and units in BCD format in RTC_DR register). With this patch, RTC driver assumes that tm->tm_years is between 2000 and 2099; tm->tm_year - 2000 have only 2 digit (0 > and <= 99). Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>

* rtc: pcf2127: Fixed bug with rtc settings and getting error timeChuanhua Han2019-07-091-9/+24
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | This adds a compatible string for m41t82. This ensures that this driver can be used for m41t82 in DM mode, too (asit was usable for this model in non-DM mode before). In addition, the HT bit has to be reset during probe, since the m41t82 chip sets it when entering battery standby mode. This patch ensures this driver works on socfpga_socrates.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-0739-79/+39
| | | | | | | | | | | | | | | | | | | | 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>
