Subject: [PATCH v1 0/2] Fixes for RX8310 RTC Configuration and rtctest Alarm

From: Emanuele Ghidoli <emanuele.ghidoli@...adex.com>

Hi,

I am submitting two patches related to the RX8310 RTC configuration:

1. **Correct RX8310 RTC Features Configuration:**
   - Sets one-minute alarm resolution.
   - Disables update IRQ.
   
   Without this patch, if the interrupt is configured in the device tree, `hwclock` fails to read the RTC as it waits for the update IRQ.

2. **Avoid rtctest Alarm Test Failures:**
   - Ensures rtctest alarm tests do not fail on hardware that only supports one-minute alarm resolution.

I know the second patch creates conflict with this one: https://lore.kernel.org/all/20240524013807.154338-1-jjang@nvidia.com/.
I think that series can reuse the rtc_get_features function I implemented.

Best regards,
Emanuele Ghidoli
