From mboxrd@z Thu Jan 1 00:00:00 1970 From: lokeshvutla@ti.com (Lokesh Vutla) Date: Fri, 14 Oct 2016 18:30:30 +0530 Subject: [PATCH 6/9] ARM: DRA7: hwmod: Do not register RTC on DRA71 In-Reply-To: <20161014130033.14172-1-lokeshvutla@ti.com> References: <20161014130033.14172-1-lokeshvutla@ti.com> Message-ID: <20161014130033.14172-7-lokeshvutla@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Nishanth Menon RTC is not available on DRA71x, so accessing any of the RTC register or clkctrl register will lead to a crash. So, do not register RTC hwmod for DRA71x.
