Subject: [PATCH 3/4] ARM: dts: am43x-epos-evm: Add rtc node with ti,no-init property
Date: Thu, 5 Mar 2015 07:13:30 -0600 [thread overview]
Message-ID: <1425561211-31003-4-git-send-email-d-gerlach@ti.com> (raw)
In-Reply-To: <1425561211-31003-1-git-send-email-d-gerlach@ti.com>
Add rtc node with ti,no-init property so that rtc hwmod does not get
initialized as the RTC IP is disabled in hardware by the board layout
on am43x-epos-evm so the SoC cannot access the IP at all. Without this,
hwmod writes to the RTC SYSCONFIG register and causes a kernel panic
during boot.
