Datasheet: https://support.epson.biz/td/api/doc_check.php?dl=app_RX8111CE&lang=en Changes in v3: * Remove macro define `RX8111_DRV_NAME` for the driver name. * Remove macro function `RX8111_TIME_BUF_IDX` and instead use the offsets as indices directly. * Remove `rx8111_setup()` that disabled extended functionality and interrupts. * Remove comments explaining register value conversions in `rx8111_read/set_time()`. * Check/clear register flag XST (oscillation stoppage) in `rx8111_read/set_time()`. * Change `vlval` to `unsigned int` in `rx8111_ioctl()`. * Remove `case RTC_VL_CLR` in `rx8111_ioctl()`. * Convert all `dev_err()` to `dev_dbg()`. * Convert all `dev_err_probe()` to `dev_dbg()` in probe. * Return without printing from `devm_rtc_register_device()` in probe. Link to v2: https://lore.kernel.org/lkml/cover.1692699931.git.waqar.hameed@axis.com/ Changes in v2: * Move dt-bindings to `trivial-rtc.yaml`.
