From mboxrd@z Thu Jan 1 00:00:00 1970 From: ohad@wizery.com (Ohad Ben-Cohen) Date: Wed, 11 Aug 2010 16:19:28 +0300 Subject: [RFC/PATCH 4/6] sdio: add general runtime PM support In-Reply-To: <1281532770-27545-1-git-send-email-ohad@wizery.com> References: <1281532770-27545-1-git-send-email-ohad@wizery.com> Message-ID: <1281532770-27545-5-git-send-email-ohad@wizery.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add generic Runtime PM handlers to sdio. When a runtime pm event kicks in, those handlers call the runtime pm handlers of the relevant SDIO function drivers. Runtime PM is still disabled by default, so this patch alone has no immediate effect.
