2020-08-26drm/bridge: ps8640: Get the EDID from eDP controlEnric Balletbo i Serra
The PS8640 DSI-to-eDP bridge can retrieve the EDID, so implement the .get_edid callback and set the flag to indicate the core to use it.

2020-08-26drm/bridge_connector: Set default status connected for eDP connectorsEnric Balletbo i Serra
In an eDP application, HPD is not required and on most bridge chips useless. If HPD is not used, we need to set initial status as connected, otherwise the connector created by the drm_bridge_connector API remains in an unknown state.

2020-08-21drm/tidss: implement WA for AM65xx erratum i2000Tomi Valkeinen
This patch implements WA for AM65xx erratum i2000, which causes YUV formats to show wrong colors. An earlier patch removed a partial WA: a8d9d7da1546349f18eb2d6b6b3a04bdeb38719d ("drm/tidss: remove AM65x PG1 YUV erratum code") The patch explains the reasoning for removal. The change in plans has been that it has become clear that there are and will be users for PG1 SoCs and as such it's good to implement the WA for PG1s. This patch adds the WA back so that it is only used on SR1.0 (which is the new name for PG1). The previous WA code didn't check the SoC revision, which this patch does.

Finalize he conversion of GMA500 to use only GPIO descriptors. The GPIO look-up-table is associated with the device directly in the GMA500 Medfield chip driver since no explicit platform type device (such as in x86/platform/intel-mid) exists: the GMA500 probes directly from the PCI device. Apparently GPIOs 128 and 34 are used on all of these so just go ahead and register those for resetting the DSI pipes.

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). We're now passing tests that failed before" * tag 'io_uring-5.9-2020-08-15' of git://git.kernel.dk/linux-block: io_uring: short circuit -EAGAIN for blocking read attempt io_uring: sanitize double poll handling io_uring: internally retry short reads io_uring: retain iov_iter state over io_read/io_write calls task_work: only grab task signal lock when needed io_uring: enable lookup of links holding inflight files io_uring: fail poll arm on queue proc failure io_uring: hold 'ctx' reference around task_work queue + execute fs: RWF_NOWAIT should imply IOCB_NOIO io_uring: defer file table grabbing request cleanup for locked requests io_uring: add missing REQ_F_COMP_LOCKED for nested requests io_uring: fix recursive completion locking on oveflow flush io_uring: use TWA_SIGNAL for task_work uncondtionally io_uring: account locked memory before potential error case io_uring: set ctx sq/cq entry count earlier io_uring: Fix NULL pointer dereference in loop_rw_iter() io_uring: add comments on how the async buffered read retry works io_uring: io_async_buf_func() need not test page bit
2020-08-16parisc: fix PMD pages allocation by restoring pmd_alloc_one()Mike Rapoport
Commit 1355c31eeb7e ("asm-generic: pgalloc: provide generic pmd_alloc_one() and pmd_free_one()") converted parisc to use generic version of pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for PMD. Restore the original version of pmd_alloc_one() for parisc, just use GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and memset.

The panel orientation needs to parsed from a device-tree and assigned to the panel's connector in order to make orientation property available to userspace.
