Subject: [PATCH v2 12/22] rtc: pm8xxx: use u32 for timestamps
Date: Thu,  2 Feb 2023 16:54:38 +0100	[thread overview]
Message-ID: <20230202155448.6715-13-johan+linaro@kernel.org> (raw)
In-Reply-To: <20230202155448.6715-1-johan+linaro@kernel.org>

The PMIC RTC registers are 32-bit so explicitly use u32 rather than
unsigned long for timestamps to reflect the hardware.

This will also help avoid unintentional range extensions when adding
support for managing an external offset.
