2012-04-13ARM: OMAP2+: declare file-local functions as staticPaul Walmsley
Several function declarations used only in the files in which they're declared should include the static keyword, but don't: arch/arm/mach-omap2/serial.c:248:6: warning: symbol 'cmdline_find_option' was not declared. Should it be static? arch/arm/mach-omap2/omap-wakeupgen.c:259:6: warning: symbol 'irq_sar_clear' was not declared. Should it be static? arch/arm/mach-omap2/board-rx51-peripherals.c:878:27: warning: symbol 'rx51_vibra_data' was not declared.

Should it be static? arch/arm/mach-omap1/fpga.c:90:6: warning: symbol 'innovator_fpga_IRQ_demux' was not declared. Should it be static? Mark all of these as static.

2011-09-21hwspinlock/core/omap: fix id issues on multiple hwspinlock devicesOhad Ben-Cohen
hwspinlock devices provide system-wide hardware locks that are used by remote processors that have no other way to achieve synchronization. To achieve that, each physical lock must have a system-wide id number that is agreed upon, otherwise remote processors can't possibly assume they're using the same hardware lock. Usually boards have a single hwspinlock device, which provides several hwspinlocks, and in this case, they can be trivially numbered 0 to (num-of-locks - 1). In case boards have several hwspinlocks devices, a different base id should be used for each hwspinlock device (they can't all use 0 as a starting id!). While this is certainly not common, it's just plain wrong to just silently use 0 as a base id whenever the hwspinlock driver is probed. This patch provides a hwspinlock_pdata structure, that boards can use to set a different base id for each of the hwspinlock devices they may have, and demonstrates how to use it with the omap hwspinlock driver. While we're at it, make sure the hwspinlock core prints an explicit error message in case an hwspinlock is registered with an id number that already exists; this will help users catch such base id issues.

2011-09-15OMAP: omap_device: when building return platform_device instead of omap_deviceKevin Hilman
All of the device init and device driver interaction with omap_device is done using platform_device pointers. To make this more explicit, have omap_device return a platform_device pointer instead of an omap_device pointer. All current users of the omap_device pointer were only using it to get at the platform_device pointer or struct device pointer, so fixing all of the users was trivial. This also makes it more difficult for device init code to directly access members of struct omap_device, and allows for easier changing of omap_device internals.

2011-02-17omap: add hwspinlock deviceSimon Que
Build and register an hwspinlock platform device. Although only OMAP4 supports the hardware spinlock module (for now), it is still safe to run this initcall on all omaps, because hwmod lookup will simply fail on hwspinlock-less platforms.
