driver core / ACPI: Represent ACPI companions using fwnode_handle

2015-03-16T22:49:03Z

Now that we have struct fwnode_handle, we can use that to point to ACPI companions from struct device objects instead of pointing to struct acpi_device directly. There are two benefits from that. First, the somewhat ugly and hackish struct acpi_dev_node can be dropped and, second, the same struct fwnode_handle pointer can be used in the future to point to other (non-ACPI) firmware device node types.

core: platform: let platform_create_bundle initialize module owner

2014-11-06T23:16:02Z

Since commit 9447057eaff8 ("platform_device: use a macro instead of platform_driver_register"), platform_driver_register() always overwrites the .owner field of a platform_driver with THIS_MODULE. This breaks platform_create_bundle() which uses it via platform_driver_probe() from within the platform core instead of the module init. Fix it by using a similar #define construct to obtain THIS_MODULE and pass it on later. Reported-by: Russell King Signed-off-by: Wolfram Sang Signed-off-by: Greg Kroah-Hartman

driver core: platform: add device binding path 'driver_override'

2014-07-08T22:31:26Z

Needed by platform device drivers, such as the upcoming vfio-platform driver, in order to bypass the existing OF, ACPI, id_table and name string matches, and successfully be able to be bound to any device, like so: echo vfio-platform > /sys/bus/platform/devices/fff51000.ethernet/driver_override echo fff51000.ethernet > /sys/bus/platform/devices/fff51000.ethernet/driver/unbind echo fff51000.ethernet > /sys/bus/platform/drivers_probe This mimics "PCI: Introduce new device binding path using pci_dev.driver_override", which is an interface enhancement for more deterministic PCI device binding, e.g., when in the presence of hotplug.

driver core: prevent deferred probe with platform_driver_probe

2013-09-26T23:18:32Z

Prevent drivers relying on platform_driver_probe from requesting deferred probing in order to avoid further futile probe attempts (either the driver has been unregistered or its probe function has been set to platform_drv_probe_fail when probing is retried). Note that several platform drivers currently return subsystem errors from probe and that these can include -EPROBE_DEFER (e.g. if a gpio request fails). Add a warning to platform_drv_probe that can be used to catch drivers that inadvertently request probe deferral while using platform_driver_probe.

Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux

2013-07-04T22:51:45Z

Pull device tree updates from Grant Likely: "This branch contains the following changes: - Removal of CONFIG_OF_DEVICE, it is always enabled by CONFIG_OF - Remove #ifdef from linux/of_platform.h to increase compiler syntax coverage - Bug fix for address decoding on Bimini and js2x powerpc platforms. - miscellaneous binding changes One note on the above. The binding changes going in from all kinds of different trees has gotten rather out of hand. I picked up some during this cycle, but even going though my tree isn't a great fit. Ian Campbell has prototyped splitting the bindings and .dtb files into a separate repository. The plan is to migrate to using that sometime in the next few kernel releases which should get rid of a lot of the churn on binding docs and .dts files" * tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux: of: Fix address decoding on Bimini and js2x machines of: remove CONFIG_OF_DEVICE usb: chipidea: depend on CONFIG_OF instead of CONFIG_OF_DEVICE of: remove of_platform_driver ibmebus: convert of_platform_driver to platform_driver driver core: move to_platform_driver to platform_device.h mfd: DT bindings for the palmas family MFD ARM: dts: omap3-devkit8000: fix NAND memory binding of/base: fix typos of: remove #ifdef from linux/of_platform.h

platform_device: use a macro instead of platform_driver_register

2013-06-03T20:59:03Z

I found a lot of mistakes using struct platform_driver without owner so I make a macro instead of the function platform_driver_register. It can set owner in it, then guys don`t care about module owner again. Signed-off-by: Libo Chen Signed-off-by: Greg Kroah-Hartman

driver core: add helper macro for platform_driver_probe() boilerplate

2013-01-18T01:39:33Z

For simple modules that contain a single platform_driver without any additional setup code then ends up being a block of duplicated boilerplate. This patch adds a new macro, module_platform_driver_probe(), which replaces the module_init()/module_exit() registrations with template functions. This macro use the same idea of module_platform_driver(). This macro is useful to stop the misuse of module_platform_driver() for removing the platform_driver_probe() boilerplate.
