| | | | | | | | | | | | Convert TWL6040 CODEC driver into a TWL6040 MFD child, it implies that MFD-level operations like register accesses, clock setting and power management are done through MFD APIs, not directly by CODEC driver anymore. To avoid conflicts with the other MFD child, vibrator registers are skipped in CODEC driver.

* mfd: twl6040: Add initial supportMisael Lopez Cruz2011-07-048-5/+1076
| | | | | | | | | | | | | | | | | | TWL6040 IC provides analog high-end audio codec functions for handset applications. It contains several audio analog inputs and outputs as well as vibrator support. It's connected to the host processor via PDM interface for audio data communication. The audio modules are controlled by internal registers that can be accessed by I2C and PDM interface. TWL6040 MFD will be registered as a child of TWL-CORE, and will have two children of its own: twl6040-codec and twl6040-vibra. This driver is based on TWL4030 and WM8350 MFD drivers.

We need to keep the IRQ disabled by default else the forceupdate or vcbypass events could trigger events that we don't need/expect to handle.

For example, Class 2 and Class 1.5 of SmartReflex can both use the interrupt notification to identify the transition of voltage or other events. Hence, the actual class does not matter for notifier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when using CONFIG_DEBUG_SLAB, we put in kfree() or kmem_cache_free() as the last user of free objects, which is not very useful, so change it to the caller of those functions instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On an architecture without CMPXCHG_LOCAL but with DEBUG_VM enabled, the VM_BUG_ON() in __pcpu_double_call_return_bool() will cause an early panic during boot unless we always align cpu_slab properly. In principle we could remove the alignment-testing VM_BUG_ON() for architectures that don't have CMPXCHG_LOCAL, but leaving it in means that new code will tend not to break x86 even if it is introduced on another platform, and it's low cost to require alignment.
