drivercore: Generalize module_platform_driver

2012-04-16T10:49:10+00:00

This patch generalizes the module_platform_driver macro and introduces a new
module_driver macro. The module_driver macro takes a driver name, a register
and a unregister function for this driver type. Using these it construct the
module init and exit sections which register and unregister the driver. Since
such init/exit sections are commonly found in drivers this macro can be used
to eliminate a lot of boilerplate code.

The macro is not intended to be used by driver modules directly, instead it
should be used to generate bus specific macros for registering drivers like
the module_platform_driver macro.

lib: devres: add convenience function to remap a resource

2012-04-05T16:12:15+00:00

Almost every platform_driver does the three steps get_resource,
request_mem_region, ioremap. This does not only lead to a lot of code
duplication, but also a huge number of similar error strings and
inconsistent error codes on failure. So, introduce a helper function
which simplifies remapping a resource and make it hard to do something
wrong and add documentation for it.

Driver core: Add iommu_ops to bus_type

2012-01-23T09:11:35+00:00

This is the starting point to make the iommu_ops used for
the iommu-api a per-bus-type structure. It is required to
easily implement bus-specific setup in the iommu-layer.
The first user will be the iommu-group attribute in sysfs.

PM / Domains: Rename struct dev_power_domain to struct dev_pm_domain

2011-07-02T12:29:54+00:00

The naming convention used by commit 7538e3db6e015e890825fbd9f86599b
(PM: Add support for device power domains), which introduced the
struct dev_power_domain type for representing device power domains,
evidently confuses some developers who tend to think that objects
of this type must correspond to "power domains" as defined by
hardware, which is not the case.  Namely, at the kernel level, a
struct dev_power_domain object can represent arbitrary set of devices
that are mutually dependent power management-wise and need not belong
to one hardware power domain.  To avoid that confusion, rename struct
dev_power_domain to struct dev_pm_domain and rename the related
pointers in struct device and struct pm_clk_notifier_block from
pwr_domain to pm_domain.

PM: Rename dev_pm_info.in_suspend to is_prepared

This patch (as1473) renames the "in_suspend" field in struct
dev_pm_info to "is_prepared", in preparation for an upcoming change.
The new name is more descriptive of what the field really means.

drivercore: revert addition of of_match to struct device

2011-05-18T18:32:23+00:00

Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time.  This was unsafe
because matching is not an atomic operation with probing a driver.  If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.

This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.
