Subject: [PATCH v2 15/21] hw/timer/exynos4210_rtc.c: Switch 1Hz ptimer to transaction-based API
Date: Tue, 8 Oct 2019 18:17:34 +0100 [thread overview]
Message-ID: <20191008171740.9679-16-peter.maydell@linaro.org> (raw)
In-Reply-To: <20191008171740.9679-1-peter.maydell@linaro.org>
Switch the exynos41210_rtc 1Hz ptimer over to the transaction-based
API. (We will switch the other ptimer used by this device in a
separate commit.)
