linux-toradex.git/drivers/amba/bus.c, branch v3.10.78 Linux kernel for Apalis and Colibri modules Drivers: amba: remove __dev* attributes. 2013-01-03T23:57:02+00:00 Greg Kroah-Hartman gregkh@linuxfoundation.org 2012-12-21T21:16:42+00:00 c571b211a70bcb04249be5cb7338f95d2ec8100f CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed, as well as the use of CONFIG_HOTPLUG. This patch does both, removing the use of CONFIG_HOTPLUG in the amba/bus.c file, and __devinit and __devinitconst in the tegra-ahb.c driver.

Platforms that wish to use the regulator API to manage their power domains can indirect via the power domain interface. This feature is only used with the vape supply of the db8500 PRCMU driver which supplies the UARTs and MMC controllers, none of which have support for managing vcore at runtime in mainline (only pl022 SPI controller does). Update that supply to have an always_on constraint until the power domain support for the system is updated so that it is enabled for these users, this is likely to have no impact on practical systems as probably at least one of these devices will be active and cause AMBA to hold the supply on anyway.
