* | | | drivers/misc/lis3lv02d/lis3lv02d_i2c.c: add lis3lv02d device tree initAnilKumar Ch2012-09-26

Also adds device tree init matching table support to lis3lv02d_i2c driver. If the driver data is passed from device tree, then this driver picks up platform data from device node through common/generic lis3lv02d.c driver.

* | | | MISC: hpilo, remove pci_disable_deviceJiri Slaby2012-09-26

But this PCI device has two functions with interrupt lines connected to a single pin. The other one is a USB host controller. So when we disable the PIN there e.g. by rmmod hpilo, the controller stops working. It is because the interrupt link is disabled in ACPI since it is not refcounted yet. See acpi_pci_link_free_irq called from acpi_pci_irq_disable. It is not the best solution whatsoever, but as a workaround until the ACPI irq link refcounting is sorted out this should fix the reported errors.

Here I deprecate (but still support) the "at25,*" properties, and add what I hope is a better alternative. These new bindings also happen to be deployed in the field and were previously submitted for consideration here: https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-May/015556.html The advantages of the new bindings are that they are similar to the I2C EEPROMs and they don't conflate read-only and the address width modes in a binary encoded blob.

Fix up mostly trivial conflicts, with the exception of drivers/usb/host/ehci-omap.c in particular, which had some re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI: centralize controller initialization") that clashed with commit 2761a6394516 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues"). In particular, commit 2761a6394516 moved the usb_add_hcd() to the *middle* of the reset sequence, which clashes fairly badly with the reset sequence re-organization (although it could have been done inside the new omap_ehci_init() function).

The subsystem has been in development for over half a year now and many drivers have already been converted. It has been in linux-next for a couple of weeks and there have been no major issues so I think it is ready for inclusion in your tree." Arnd Bergmann <arnd@arndb.de>: "Very much Ack on the new subsystem. It uses the interface declarations as the previously separate pwm drivers, so nothing changes for now in the drivers using it, although it enables us to change those more easily in the future if we want to. This work is also one of the missing pieces that are required to eventually build ARM kernels for multiple platforms, which is currently prohibited (amongs other things) by the fact that you cannot have more than one driver exporting the pwm functions."

| * | | pwm: Conflict with legacy PWM APIThierry Reding2012-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to avoid duplicate symbols with legacy PWM API implementations, the new PWM framework needs to conflict with any of the existing legacy implementations. This is done in two ways: for implementations provided by drivers, a conflict is added to the driver to ensure it will have to be ported to the PWM subsystem before it can coexist with other PWM providers. For architecture-specific code, the conflict is added to the PWM symbol to avoid confusion when a previously picked platform or machine can no longer be selected because of the PWM subsystem being included.
