From mboxrd@z Thu Jan 1 00:00:00 1970 From: khilman@ti.com (Kevin Hilman) Date: Mon, 11 Jul 2011 16:29:29 -0700 Subject: [PATCH 4/4] OMAP: PM: disable idle on suspend for GPIO and UART In-Reply-To: <1310426969-30306-1-git-send-email-khilman@ti.com> References: <1310426969-30306-1-git-send-email-khilman@ti.com> Message-ID: <1310426969-30306-5-git-send-email-khilman@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Until these drivers are runtime PM converted, their device power states are managed by calling custom driver hooks late in the idle/suspend path. Therefore, do not let the suspend/resume core code automatically idle these devices since they will be managed manually by the OMAP PM core very late in the idle/suspend path.
