From mboxrd@z Thu Jan 1 00:00:00 1970 From: nm@ti.com (Nishanth Menon) Date: Thu, 28 Jul 2011 17:07:28 -0500 Subject: [PATCH 2/2] OMAP: PM: omap_device: add few quick access functions Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Provide a quick set of access functions: a) Convert omap_device to platform_device - This is the flip of to_omap_device for equivalent usage b) Convert omap_device to device pointer - This is useful for most devices that need to go through standard linux functions that take device pointer. c) Convert hwmod to device pointer - This wrapper provides ability for drivers to convert directly from hwmod name back to device pointer without having to handle this on a driver by driver basis Change-Id: I0fe16eeb41c32d5b166d5cb3f78af4fda140d398 Signed-off-by: Nishanth Menon --- arch/arm/plat-omap/include/plat/omap_device.h | 13 +++++++++++++ 1 files changed, 13 insertions(+), 0 deletions(-) diff --git a/arch/arm/plat-omap/include/plat/omap_device.h b/arch/arm/plat-omap/include/plat/omap_device.h index 7a3c046..11cb471 100644 --- a/arch/arm/plat-omap/include/plat/omap_device.h +++ b/arch/arm/plat-omap/include/plat/omap_device.h @@ -150,5 +150,18 @@ struct omap_device_pm_latency { /* Get omap_device pointer from platform_device pointer */ #define to_omap_device(x) container_of((x), struct omap_device, pdev) +/* Convert omap_device to platform device pointer */ +#define omap_device_get_pdev(x) (&(x)->pdev) +/* Convert omap_device to device pointer */ +#define omap_device_get_dev(x) (&omap_device_get_pdev(x)->dev) +/* Convert omap_hwmod name to device pointer */ +static inline struct device *omap_hwmod_name_get_dev(const char *oh_name) +{ + struct omap_device *od; + od = omap_hwmod_name_get_dev(oh_name); + if (IS_ERR_OR_NULL(od)) + return ERR_PTR(od ?
