Subject: [PATCH 2/4] rtc: s3c: Add time range
Date: Tue, 19 Oct 2021 16:17:22 +0300 [thread overview]
Message-ID: <20211019131724.3109-3-semen.protsenko@linaro.org> (raw)
In-Reply-To: <20211019131724.3109-1-semen.protsenko@linaro.org>
This RTC driver only accepts dates from 2000 to 2099 year. It starts
counting from 2000 to avoid Y2K problem, and S3C RTC only supports 100
years range. Provide this info to RTC framework.
