2020-03-30ptp: Avoid deadlocks in the programmable pin code.Richard Cochran1-0/+19
The PTP Hardware Clock (PHC) subsystem offers an API for configuring programmable pins. User space sets or gets the settings using ioctls, and drivers verify dialed settings via a callback. Drivers may also query pin settings by calling the ptp_find_pin() method. Although the core subsystem protects concurrent access to the pin settings, the implementation places illogical restrictions on how drivers may call ptp_find_pin(). When enabling an auxiliary function via the .enable(on=1) callback, drivers may invoke the pin finding method, but when disabling with .enable(on=0) drivers are not permitted to do so. With the exception of the mv88e6xxx, all of the PHC drivers do respect this restriction, but still the locking pattern is both confusing and unnecessary. This patch changes the locking implementation to allow PHC drivers to freely call ptp_find_pin() from their .enable() and .verify() callbacks.

2020-03-30PCI: Add support for root bus sizingIvan Kokshaysky1-0/+1
In certain cases we should be able to enumerate IO and MEM ranges of all PCI devices installed in the system, and then set respective host bridge apertures basing on calculated size and alignment. Particularly when firmware is broken and fails to assign bridge windows properly, like on Alpha UP1500 platform. Actually, almost everything is already in place, and required changes are minimal: - add "size_windows" flag to struct pci_host_bridge: when set, it instructs __pci_bus_size_bridges() to continue with the root bus; - in the __pci_bus_size_bridges() path: add checks for bus->self, as it can legitimately be null for the root bus.

2020-03-30PCI: Use ioremap(), not phys_to_virt() for platform ROMMikel Rychliski1-1/+0
On some EFI systems, the video BIOS is provided by the EFI firmware. The boot stub code stores the physical address of the ROM image in pdev->rom. Currently we attempt to access this pointer using phys_to_virt(), which doesn't work with CONFIG_HIGHMEM. On these systems, attempting to load the radeon module on a x86_32 kernel can result in the following: BUG: unable to handle page fault for address: 3e8ed03c #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page *pde = 00000000 Oops: 0000 [#1] PREEMPT SMP CPU: 0 PID: 317 Comm: systemd-udevd Not tainted 5.6.0-rc3-next-20200228 #2 Hardware name: Apple Computer, Inc.

Instead of calling the helper function pci_platform_rom() which uses phys_to_virt(), call ioremap() directly on the pdev->rom. radeon_read_platform_bios() previously directly accessed an __iomem pointer. Avoid this by calling memcpy_fromio() instead of kmemdup(). pci_platform_rom() now has no remaining callers, so remove it.

2020-03-30ceph: consider inode's last read/write when calculating wanted capsYan, Zheng1-0/+1
Add i_last_rd and i_last_wr to ceph_inode_info. These fields are used to track the last time the client acquired read/write caps for the inode. If there is no read/write on an inode for 'caps_wanted_delay_max' seconds, __ceph_caps_file_wanted() does not request caps for read/write even there are open files. Call __ceph_touch_fmode() for dir operations. __ceph_caps_file_wanted() calculates dir's wanted caps according to last dir read/modification. If there is recent dir read, dir inode wants CEPH_CAP_ANY_SHARED caps. If there is recent dir modification, also wants CEPH_CAP_FILE_EXCL. Readdir is a special case. Dir inode wants CEPH_CAP_FILE_EXCL after readdir, as with that, modifications do not need to release CEPH_CAP_FILE_SHARED or invalidate all dentry leases issued by readdir.

2020-03-30ceph: attempt to do async create when possibleJeff Layton1-0/+3
With the Octopus release, the MDS will hand out directory create caps. If we have Fxc caps on the directory, and complete directory information or a known negative dentry, then we can return without waiting on the reply, allowing the open() call to return very quickly to userland. We use the normal ceph_fill_inode() routine to fill in the inode, so we have to gin up some reply inode information with what we'd expect the newly-created inode to have. The client assumes that it has a full set of caps on the new inode, and that the MDS will revoke them when there is conflicting access. This functionality is gated on the wsync/nowsync mount options.

Track and correctly handle directory caps for asynchronous operations. Add aliases for Frc caps that we now designate at Dcu caps (when dealing with directories). Unlike file caps, we don't reclaim these when the session goes away, and instead preemptively release them. In-flight async dirops are instead handled during reconnect phase. The client needs to re-do a synchronous operation in order to re-get directory caps.

2020-03-30mfd: sc27xx: Add USB charger type detection supportBaolin Wang1-0/+7
The Spreadtrum SC27XX series PMICs supply the USB charger type detection function, and related registers are located on the PMIC global registers region, thus we implement and export this function in the MFD driver for users to get the USB charger type.

2020-03-30mfd: rk808: Convert RK805 to shutdown/suspend hooksRobin Murphy1-1/+0
RK805 has the same kind of dual-role sleep/shutdown pin as RK809/RK817, so it makes little sense for the driver to have to have two completely different mechanisms to handle essentially the same thing. Move RK805 over to the shutdown/suspend flow to clean things up. Signed-off-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2020-03-30mfd: rk808: Reduce shutdown duplicationRobin Murphy1-1/+0

2020-03-30ethtool: provide timestamping information with TSINFO_GET requestMichal Kubecek1-0/+17
Implement TSINFO_GET request to get timestamping information for a network device. This is traditionally available via ETHTOOL_GET_TS_INFO ioctl request. Move part of ethtool_get_ts_info() into common.c so that ioctl and netlink code use the same logic to get timestamping information from the device. v3: use "TSINFO" rather than "TIMESTAMP", suggested by Richard Cochran Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

Implement EEE_SET netlink request to set EEE settings of a network device. These are traditionally set with ETHTOOL_SEEE ioctl request. The netlink interface allows setting the EEE status for all link modes supported by kernel but only first 32 link modes can be set at the moment as only those are supported by the ethtool_ops callback.
