* drivers: rtc: add max313xx series rtc driverChris Packham2023-03-303-0/+473
| | | | | | | | | | | | | | Adding support for Analog Devices MAX313XX series RTCs. This is ported from the Linux driver and adapted for use in u-boot. Notable differences are - handling of tm_year and tm_mon differ - clock source support is omitted - hwmon support for the MAX31328 and MAX31343 is omitted - rtc_ops->reset is added Signed-off-by: Chris Packham <judge.packham@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

* rtc: abx8xx: Add support for reading RAMSean Anderson2023-01-111-17/+51
| | | | | | | | | | | | | This adds support for reading the battery-backed memory present on these RTCs. This modifies the read/write methods to access the RAM instead of raw register offsets. No one was using these in-tree, so we should be fine changing them. We use the "standard" address space window to access the RAM. The extension RAM address register has some reserved bits, but we write the whole thing for simplicity (as these bits default to 0). Signed-off-by: Sean Anderson <sean.anderson@seco.com>

* | rtc: ds1307: Handle oscillator-stop bit correctlyMark Tomlinson2021-10-121-52/+20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DS1307 driver was originally based on the DS1337 driver. However, the functionality of the clock set/get functions has diverged. In the original DS1337 driver, the set/get functions did the following: 1) Setting the clock ensured the oscillator was enabled. 2) Getting the clock checked and reset the oscillator-stop flag. The DS1307 does not have an oscillator-stop flag, but the driver tried (incorrectly) to emulate this by ensuring the oscillator was running. It really makes no sense to start a stopped clock without setting it. This patch makes the DS1307 driver behave like the original DS1337 driver again. For the DS1307 itself, this is just a removal of code, since there is no oscillator-fail bit to check or reset, and the clock is started when it is set. Since the DS1307 driver can now also be used for the DS1337 and DS1340 which do have this bit, add code to handle the oscillator-stop bit in the same was the original DS1337 driver did -- i.e. report that the oscillator had stopped and clear the flag. This means that setting the date using the date command (which does both a get and a set) will now clear the oscillator-stop flag in addition to setting and starting the clock. The old-style (non-DM) code has not been updated and will be removed in a future patch. Note that this older code does not support the DS1337, as there is a separate driver for this. Also note that the original (DM) code used the wrong control-register address for the DS1337. Signed-off-by: Mark Tomlinson <mark.tomlinson@alliedtelesis.co.nz>

| | | | | | | | | | | | | | | | | | | | 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.

* rtc: ds1307: Fix incorrect clock reset for DS13xxCallum Sinclair2021-09-011-13/+56
| | | | | | | | | | | | | The ds1307 driver also supports the DS1339 and DS1340. However, in ds1307_rtc_reset the register writes assume that the chip is a DS1307. This is evident in the writing of bits SQWE, RS1, RS0 to the control register. While this applies correctly to the DS1307, on a DS1340 the control register doesn't contain those bits (instead, the register is used for clock calibration). By writing these bits the clock calibration will be changed and the chip can become non-functional after a reset call. Signed-off-by: Callum Sinclair <callum.sinclair@alliedtelesis.co.nz>
