Add a 'num_lanes' field to allow drivers to provide a the number of lanes if not in DT or using a custom DT property. A driver can provide a non-zero value which is used if the DT doesn't have a 'num-lanes' property. Link: https://lore.kernel.org/r/20200821035420.380495-24-robh@kernel.orgSigned-off-by:

The config space is divided in half for type 0 and type 1 accesses, but this is pointless as there's only one iATU window which is reconfigured on each access. The only platform doing something custom is TI Keystone (surprise!). It does its own mapping of the config space to avoid spliting the config space and never actually uses va_cfg1_base as it has its own config space accessors. With the splitting removed, Keystone can use the default mapping of config space. Link: https://lore.kernel.org/r/20200821035420.380495-20-robh@kernel.orgSigned-off-by:

The PCI bridge resources are stored in pci_host_bridge.windows, so there's no need to store them in a DWC specific struct. There's also no need to parse the resources and store them a 2nd time as they are mainly used for one time setup of iATU windows.

Similar to pcibios_add_bus(), call pci_ops.add_bus() when the root bus is added. This allows host bridge drivers to do any setup requiring a bus pointer.

Now that all the platforms with custom config access handling define their own pci_ops, let's split the default config accessors to use different pci_ops for root and child buses. With this, we can use the generic config accessors. The child bus accesses mainly require a .map_bus() hook to reconfigure the iATU on each config space access.

In preparation to allow drivers to set their own root and child pci_ops instead of using the DWC specific config space ops, we need to make the pci_host_bridge pointer available and move setting the bridge->ops and bridge->child_ops pointer to before the .host_init() hook.

The Designware DBI space contains the root bus bridge config space. Platforms needing custom {rd,wr}_own_conf functions are also the ones needing custom {read,write}_dbi ops functions and the access sequences are the same.

Pull io_uring fixes from Jens Axboe: "A few differerent things in here. Seems like syzbot got some more io_uring bits wired up, and we got a handful of reports and the associated fixes are in here. General fixes too, and a lot of them marked for stable. Lastly, a bit of fallout from the async buffered reads, where we now more easily trigger short reads. Some applications don't really like that, so the io_read() code now handles short reads internally, and got a cleanup along the way so that it's now easier to read (and documented).

There's a bit of confusion on the matching pairs of poll vs double poll, depending on if the request is a pure poll (IORING_OP_POLL_ADD) or poll driven retry. Add io_poll_get_double() that returns the double poll waitqueue, if any, and io_poll_get_single() that returns the original poll waitqueue. With that, remove the argument to io_poll_remove_double(). Finally ensure that wait->private is cleared once the double poll handler has run, so that remove knows it's already been seen.
