Date: Fri, 21 Jun 2013 19:01:36 +0300 From: Grygorii Strashko <grygorii.strashko@...com> To: Wolfram Sang <wsa@...-dreams.de>, Tony Lindgren <tony@...mide.com>, Samuel Ortiz <sameo@...ux.intel.com> CC: <linux-kernel@...r.kernel.org>, <linux-omap@...r.kernel.org>, <linux-i2c@...r.kernel.org>, "Strashko, Grygorii" <grygorii.strashko@...com> Subject: [RESEND][1/2] i2c: omap: convert to module_platform_driver() From: "Strashko, Grygorii" <grygorii.strashko@...com> The OMAP I2C driver has a relation to pinctrl-single driver. As result, its probe will be deferred during system boot until late init time, because the pinctrl-single is initizalized as moudle/device init time. This, in turn, will delay initialization of all I2C devices (like mfd, I2C regulators and etc.) and cause boot delay (more over, it can broken initialization of drivers which are not ready to use deferred probe mechanism yet, for example DSS). There are no sense to keep OMAP I2C initialization on subsys init layer any more, hence shift it to module/device layer where the i2c <--> pinctrl-single dependency is resolved in drivers/Makefile now. Signed-off-by: Grygorii Strashko <grygorii.strashko@...com> --- Hi Wolfram, The prerequsite patch https://lkml.org/lkml/2013/6/6/98 has been merged in linux-next, so re-send 11c506d drivers/rtc/rtc-twl.c: fix rtc_reg_map initialization In addition, I've removed CC list. -grygorii drivers/i2c/busses/i2c-omap.c | 14 +------------- 1 file changed, 1 insertion(+), 13 deletions(-) diff --git a/drivers/i2c/busses/i2c-omap.c b/drivers/i2c/busses/i2c-omap.c index 4cc2f05..70d3fed 100644 --- a/drivers/i2c/busses/i2c-omap.c +++ b/drivers/i2c/busses/i2c-omap.c @@ -1342,19 +1342,7 @@ static struct platform_driver omap_i2c_driver = { }, }; -/* I2C may be needed to bring up other drivers */ -static int __init -omap_i2c_init_driver(void) -{ - return platform_driver_register(&omap_i2c_driver); -} -subsys_initcall(omap_i2c_init_driver); - -static void __exit omap_i2c_exit_driver(void) -{ - platform_driver_unregister(&omap_i2c_driver); -} -module_exit(omap_i2c_exit_driver); +module_platform_driver(omap_i2c_driver); MODULE_AUTHOR("MontaVista Software, Inc.
