Subject: [PATCH 6/7] arm64: dts: exynos: Mark arch_timer device as not-fw-configured on TM2(e)
Date: Mon, 08 Oct 2018 14:50:08 +0200 [thread overview]
Message-ID: <20181008125009.3721-7-m.szyprowski@samsung.com> (raw)
In-Reply-To: <20181008125009.3721-1-m.szyprowski@samsung.com>
TM2(e) boards use old firmware, which some PCSI requirements and doesn't
properly configure arch virtual timers, so add property indicating this
state. This enables respective workarounds in the timer driver.
