rtc: rx8025: revise single register write to use offset

2021-10-03T18:40:56+00:00

Writing of individual registers was not functioning correctly as a 0 'offset' byte under DM-managed I2C was being appended in front of register we wanted to access. Signed-off-by: Mathew McBride

rtc: rx8025: set date in a single i2c transaction

2021-10-03T18:40:56+00:00

The RX8025/RX8035 does not like having it's time registers set byte-by-byte in separate I2C transactions. From the note at the top of the file, it appears target-dependent workarounds have been used in the past for this. Resolve this by setting the time registers in a single I2C transaction. As part of this, also ensure the '24/12' flag in the RTC is reset before writing the date (instead of after), otherwise the RX8035 will clear the seconds and minutes registers. Tested on Traverse Ten64 (NXP LS1088A) with RX8035. Signed-off-by: Mathew McBride

rtc: rx8025: add support for EPSON RX8035.

2021-10-03T18:40:56+00:00

The RX8035 is a newer model from EPSON which is very similar in operation to the RX8025. The changes mirror similar ones that will be in Linux 5.15: https://lore.kernel.org/all/20210709044518.28769-2-matt@traverse.com.au/ The UBOOT_DRIVER ID has also been corrected, previously it declared itself as rx8010sj_rtc which is a different driver.

rtc: rx8025: drop non-DM support

2021-10-03T18:40:56+00:00

A search of the tree showed there is only one user of this driver (soon to be two) - board/socrates The second user will be the Traverse Ten64 board. Both these boards have DM_RTC. Signed-off-by: Mathew McBride

rtc: remove CONFIG_CMD_DATE dependency

2018-07-25T13:00:24+00:00

The EFI subsystem accesses the real time clock and is enabled by default. So we should drop any CONFIG_CMD_DATE dependency from the real time clock drivers. Signed-off-by: Heinrich Schuchardt Signed-off-by: Alexander Graf

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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

rtc: rx8025: remove redundant code in rtc_reset

2018-04-07T00:45:44+00:00

As of commit 1a1fa2406689 ("rtc: Set valid date after reset") the command "date reset" will set the date/time to 2000-01-01 0:00:00 after calling rtc_reset(). This means that the rx8025 implementation of rtc_reset() does not need to call rtc_set(). Signed-off-by: Chris Packham
