From mboxrd@z Thu Jan 1 00:00:00 1970 From: jonmason@broadcom.com (Jon Mason) Date: Fri, 18 Dec 2015 16:37:56 -0500 Subject: [PATCH 3/3] arm: dts: bcm5301x: Add syscon based reboot in DT In-Reply-To: <1450474676-10210-1-git-send-email-jonmason@broadcom.com> References: <1450474676-10210-1-git-send-email-jonmason@broadcom.com> Message-ID: <1450474676-10210-3-git-send-email-jonmason@broadcom.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add the ability to reboot via a reset of the processor. This is achieved via a write of 0x39 to the CRU Reset Register. Unfortunately, this only resets the core and not the other IP blocks. So if possible, other methods should be used on the individual boards.
