None of the Kconfig currently controlling compilation of any of
the files here are tristate, meaning that none of it currently
is being built as a module by anyone.
We need not be concerned about .remove functions and blocking the
unbind sysfs operations, since that was already done in a recent
commit.
Lets remove any remaining modular references, so that when reading the
drivers there is no doubt they are builtin-only.
All drivers get mostly the same changes, so they are handled in batch.
Changes are (1) convert to builtin_amba_driver, (2) delete module.h
include where unused, and (3) relocate the description into the
comments so we don't need MODULE_DESCRIPTION and associated tags.
The etm3x and etm4x use module_param_named, and have been adjusted
to just include moduleparam.h for that purpose.
In commit f309d4443130bf814e991f836e919dca22df37ae ("platform_device:
better support builtin boilerplate avoidance") we introduced the
builtin_driver macro.
Here we use that support and extend it to amba driver registration,
so where a driver is clearly non-modular and builtin-only, we can
update with the simple mapping of
module_amba_driver(...) ---> builtin_amba_driver(...)
Since module_amba_driver() uses the same init level priority as
builtin_amba_driver() the init ordering remains unchanged with
this commit.

As already demonstrated with PCI [1] and the platform bus [2], a driver_override property in sysfs can be used to bypass the id matching of a device to a AMBA driver. This can be used by VFIO to bind to any AMBA device requested by the user.

Replace the amba_pclk_enable and amba_pclk_disable macros with static inline functions and remove checks for IS_ERR. The amba bus clock won't be ERR because probe would fail before the use of these functions.

CoreSight components are compliant with the ARM CoreSight architecture specification and can be connected in various topologies to suit a particular SoC tracing needs. These trace components can generally be classified as sources, links and sinks. Trace data produced by one or more sources flows through the intermediate links connecting the source to the currently selected sink. The CoreSight framework provides an interface for the CoreSight trace drivers to register themselves with. It's intended to build up a topological view of the CoreSight components and configure the correct serie of components on user input via sysfs. For eg., when enabling a source, the framework builds up a path consisting of all the components connecting the source to the currently selected sink(s) and enables all of them. The framework also supports switching between available sinks and provides status information to user space applications through the debugfs interface.

Add support for a extended PL022 which has an extra register for controlling up to five chip select signals. This controller is found on the AXM5516 SoC. Unfortunately the PrimeCell identification registers are identical to a standard ARM PL022. To work around this, the peripheral ID must be overridden in the device tree using the "arm,primecell-periphid" property with the value 0x000b6022.

This patch adds Qualcomm amba vendor Id to the list. This ID is used in mmci driver. The ID selected in same lines like 0x41 is "A" for ARM, 0x51 is "Q" for Qualcomm. As there are no physical register on Qcom SOC for amba vendor id, this is a fake ID assigned based on "Q" prefix from Qualcomm.

Pull ARM updates from Russell King:
"Included in this series are:
1. BE8 (modern big endian) changes for ARM from Ben Dooks
2. big.Little support from Nicolas Pitre and Dave Martin
3. support for LPAE systems with all system memory above 4GB
4. Perf updates from Will Deacon
5. Additional prefetching and other performance improvements from Will.
6. Neon-optimised AES implementation fro Ard.
7. A number of smaller fixes scattered around the place.
There is a rather horrid merge conflict in tools/perf - I was never
notified of the conflict because it originally occurred between Will's
tree and other stuff. Consequently I have a resolution which Will
forwarded me, which I'll forward on immediately after sending this
mail.
The other notable thing is I'm expecting some build breakage in the
crypto stuff on ARM only with Ard's AES patches. These were merged
into a stable git branch which others had already pulled, so there's
little I can do about this. The problem is caused because these
patches have a dependency on some code in the crypto git tree - I
tried requesting a branch I can pull to resolve these, and all I got
each time from the crypto people was "we'll revert our patches then"
which would only make things worse since I still don't have the
dependent patches. I've no idea what's going on there or how to
resolve that, and since I can't split these patches from the rest of
this pull request, I'm rather stuck with pushing this as-is or
reverting Ard's patches.
Since it should "come out in the wash" I've left them in - the only
build problems they seem to cause at the moment are with randconfigs,
and since it's a new feature anyway. However, if by -rc1 the
dependencies aren't in, I think it'd be best to revert Ard's patches"
I resolved the perf conflict roughly as per the patch sent by Russell,
but there may be some differences. Any errors are likely mine. Let's
see how the crypto issues work out..
