2020-03-02rtc: m41t62: add compatible for m41st87Marek Vasut1-0/+1
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>
2019-04-25rtc: m41t62: add compatible for m41t82Simon Goldschmidt1-0/+11
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.

2018-12-03rtc: m41t62: Convert the RTC driver to support the driver model (DM)Lukasz Majewski1-0/+77
After this change the m41t62.c can be used with RTC subsystem (i.e. date command) which uses device model (DM). Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Stefan Roese <sr@denx.de>

2018-07-25rtc: remove CONFIG_CMD_DATE dependencyHeinrich Schuchardt1-4/+0
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 <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>

2012-07-07rtc/m41t62: Add support for M41T82 with HT (Halt Update)Stefan Roese1-1/+9
Add support for the M41T82 RTC to the m41t62 driver. The only difference that needs to be handled by this driver, is to clear the HT (Halt Update) bit upon reset. This bit is not used on the M41T62, so its save to clear this bit always. The M41T82 support will be used by the X600 (SPEAr600) board support. Signed-off-by: Stefan Roese <sr@denx.de>

2008-05-03RTC: Fix month offset by one problem in M41T62 RTC driverStefan Roese1-2/+2
This patch fixes a problem with the month being read and written incorrectly (offset by one). This only gets visible by also using the Linux driver (rtc-m41t80). Tested on AMCC Canyonlands. Signed-off-by: Stefan Roese <sr@denx.de>
2008-03-20LWMON5: POST RTC fixYuri Tikhonov1-1/+3
Modify the RTC API to provide one a status for the time reported by the rtc_get() function: 0 - a reliable time is guaranteed, < 0 - a reliable time isn't guaranteed (power fault, clock issues, and so on). The RTC chip drivers are responsible for providing this info if the corresponding chip supports such functionality. If not - always report that the time is reliable. The POST RTC test was modified to detect the RTC faults utilizing this new rtc_get() feature. Signed-off-by: Yuri Tikhonov <yur@emcraft.com>
