ARM: 7362/1: AMBA: Add module_amba_driver() helper macro for amba_driver

2012-03-16T23:32:35+00:00

For simple modules that contain a single amba_driver without any
additional setup code then ends up being a block of duplicated
boilerplate. This patch adds a new macro, module_amba_driver(),
which replaces the module_init()/module_exit() registrations with
template functions.

ARM: amba: add amba_device allocation/add/put functions

2012-01-25T11:02:01+00:00

Add functions to allocate and initialize AMBA device structures, and
add them to the Linux device manager.  This allows us to kill this
type of operation from individual platforms, moving it to core code.

ARM: amba: Move definition of struct amba_id to mod_devicetable.h

2011-11-22T10:58:30+00:00

The general kernel infrastructure for adding module alises during
module post processing expects the affected device type
identification structures in a common header
.

This patch simple moves struct amba_id to the common header, and
adds the appropriate include in .

ARM: 6758/1: amba: support pm ops

2011-02-23T16:26:46+00:00

Support pm_ops in the AMBA bus, required to allow drivers to use runtime pm.
The implementation of AMBA bus pm ops is based on the platform bus
implementation.

ARM: amba: make amba_driver id_table const

2011-02-23T16:24:22+00:00

Now that the bus level code deals with a const id table, we can also
make the ID table in the amba_driver structure also const.

ARM: amba: make probe() functions take const id tables

2011-02-23T16:24:14+00:00

Make Primecell driver probe functions take a const pointer to their
ID tables.  Drivers should never modify their ID tables in their
probe handler.

ARM: 6662/1: amba: make amba_bustype non-static

2011-02-23T16:24:08+00:00

Export amba_bustype struct so it can be used for things like registering
bus notifiers.

ARM: 6467/1: amba: optional PrimeCell core voltage switch

2010-11-26T10:59:12+00:00

On some contemporary sub-micron SoCs, peripherals on the chip have
power domain switches, i.e. the voltage to the core may be turned
off to conserve power. In the Ux500 we have this for out PrimeCell
derivates.

This patch makes it possible to specify an (optional) regulator to
handle the voltage domain switch on AMBA PrimeCells, modeled very
similar to how block clocks are handled.

Additional amba_vcore_[enable|disable] calls are supplied to make
it possible introduce optional powering off of the core voltage.
Using this will require code to spool/unspool any core HW state.

ARM: 6368/1: move the PrimeCell IDs to use macros

2010-10-08T09:02:27+00:00

This make four macros for the PrimeCell ID register available to
drivers that use them witout using the PrimeCell/AMBA bus
abstraction and struct amba_device. It also moves the magic
PrimeCell CID "B105F00D" to the bus.h header file.
