rtc: rx8025: fix incorrect register reference

2025-11-13T20:34:40+00:00

commit 162f24cbb0f6ec596e7e9f3e91610d79dc805229 upstream. This code is intended to operate on the CTRL1 register, but ctrl[1] is actually CTRL2. Correctly, ctrl[0] is CTRL1.

rtc: Switch i2c drivers back to use .probe()

2023-06-06T21:29:37+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

rtc: Include when appropriate

2022-11-15T20:01:51+00:00

The kstrto() functions have been moved from kernel.h to kstrtox.h. So, include the latter directly in the appropriate files.

rtc: rx8025: Convert to .probe_new()

.probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in .probe(). Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221021130706.178687-10-u.kleine-koenig@pengutronix.de Signed-off-by: Alexandre Belloni

rtc: rx8025: fix 12/24 hour mode detection on RX-8035

2022-07-26T14:49:45+00:00

The 12/24hr flag in the RX-8035 can be found in the hour register, instead of the CTRL1 on the RX-8025. This was overlooked when support for the RX-8035 was added, and was causing read errors when the hour register 'overflowed'. To deal with the relevant register not always being visible in the relevant functions, determine the 12/24 mode at startup and store it in the driver state.

rtc: rx8025: use .set_offset/.read_offset

2021-11-09T23:45:57+00:00

The driver has its own sysfs file to adjust the clock. Fortunately, it is already in pbb, however, the sign it expects is the opposite of what the RTC core does (which actually aligns with the RTC).
