Pull firewire updates from Takashi Sakamoto: "This consist of three parts; UAPI update, OHCI driver update, and several bug fixes. Firstly, the 1394 OHCI specification defines method to retrieve hardware time stamps for asynchronous communication, which was previously unavailable in user space. This adds new events to the UAPI, allowing applications to retrieve the time when asynchronous packet are received and sent. The new events are tested in the bleeding edge of libhinawa and look to work well. The new version of libhinawa will be released after current merge window is closed: https://git.kernel.org/pub/scm/libs/ieee1394/libhinawa.git/ Secondly, the FireWire stack includes a PCM device driver for 1394 OHCI hardware, This change modernizes the driver by managed resource (devres) framework. Lastly, bug fixes for firewire-net and firewire-core" * tag 'firewire-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: (25 commits) firewire: net: fix use after free in fwnet_finish_incoming_packet() firewire: core: obsolete usage of GFP_ATOMIC at building node tree firewire: ohci: release buffer for AR req/resp contexts when managed resource is released firewire: ohci: use devres for content of configuration ROM firewire: ohci: use devres for IT, IR, AT/receive, and AT/request contexts firewire: ohci: use devres for list of isochronous contexts firewire: ohci: use devres for requested IRQ firewire: ohci: use devres for misc DMA buffer firewire: ohci: use devres for MMIO region mapping firewire: ohci: use devres for PCI-related resources firewire: ohci: use devres for memory object of ohci structure firewire: fix warnings to generate UAPI documentation firewire: fix build failure due to missing module license firewire: cdev: implement new event relevant to phy packet with time stamp firewire: cdev: add new event to notify phy packet with time stamp firewire: cdev: code refactoring to dispatch event for phy packet firewire: cdev: implement new event to notify response subaction with time stamp firewire: cdev: add new event to notify response subaction with time stamp firewire: cdev: code refactoring to operate event of response firewire: core: implement variations to send request and wait for response with time stamp ...
