Subject: [PATCH 02/15] rtc: hym8563: fix incorrect maximum clock rate handling
Date: Thu, 10 Jul 2025 11:20:22 -0400	[thread overview]
Message-ID: <20250710-rtc-clk-round-rate-v1-2-33140bb2278e@redhat.com> (raw)
In-Reply-To: <20250710-rtc-clk-round-rate-v1-0-33140bb2278e@redhat.com>

When hym8563_clkout_round_rate() is called with a requested rate higher
than the highest supported rate, it currently returns 0, which disables
the clock. According to the clk API, round_rate() should instead return
the highest supported rate. Update the function to return the maximum
supported rate in this case.

Fixes: dcaf038493525 ("rtc: add hym8563 rtc-driver")
