The runtime pm resume/suspend will enable/disable pclk (ISI peripheral clock). We have to call runtime_pm_get_sync()/runtime_pm_put() when we need to access ISI registers. In atmel_isi_probe(), remove the isi disable code as at that moment ISI peripheral clock is not enable yet. Besides, clock_start()/clock_stop() is used to control the mclk, not the ISI peripheral clock. So move this to start[stop]_streaming() function. Signed-off-by:

Josh Wu authored
In current code, stop_streaming() will just return if ISI is still working in the codec. But this is incorrect, we need to disable ISI even it is working on the codec, otherwise stop_streaming() will not work as we expected. Signed-off-by:

Commit 813f5c0a ("media: Change media device link_notify behaviour") modified the media controller link setup notification API and updated the OMAP3 ISP driver accordingly. As a side effect it introduced a bug by turning power on after setting the link instead of before. This results in sub-devices not being powered down in some cases when they should be. Fix it.

The async notifier was registered before the v4l2_device was registered and before the notifier callbacks were set. This could lead to missing the bound() and complete() callbacks and to attempting to spin_lock() and uninitialised spin lock. Also fix unregistering the async notifier in the case of an error --- the function may not fail anymore after the notifier is registered.

The last CVT standard introduced reduced blanking version 2 which is signaled by a vsync of 8. Log this. Signed-off-by:
-
Prashant Laddha authored
Added support for reduced blanking version 2 (RB v2) in cvt timings. Standard specifies a fixed vsync pulse of 8 lines to indicate RB v2 timings. Vertical back porch is fixed at 6 lines and vertical front porch is remainder of vertical blanking time. For RB v2, horizontal blanking is fixed at 80 pixels. Horizontal sync is fixed at 32. All horizontal timing counts (active pixels, front, back porches) can be specified upto a precision of 1. RB v2 allows for non standard aspect ratios. In RB v2 vsync does not indicate aspect ratio. In absence of aspect ratio v4l2_detect_cvt() cannot calculate image width from image height. Hence extending the v4l2_detect_cvt() to pass image width in case of RB v2. Signed-off-by:

Commit 835a6a2f ("Bluetooth: Stop sabotaging list poisoning") thought that the code was sabotaging the list poisoning when NULL'ing out the list pointers and removed it. But what was going on was that the bluetooth code was using NULL pointers for the list as a way to mark it empty, and that commit just broke it (and replaced the test with NULL with a "list_empty()" test on a uninitialized list instead, breaking things even further). So fix it all up to use the regular and real list_empty() handling (which does not use NULL, but a pointer to itself), also making sure to initialize the list properly (the previous NULL case was initialized implicitly by the session being allocated with kzalloc()) This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong An. [ I would normally expect to get this through the bt tree, but I'm going to release -rc1, so I'm just committing this directly - Linus ] Reported-and-tested-by:

Pull SCSI target updates from Nicholas Bellinger: "It's been a busy development cycle for target-core in a number of different areas. The fabric API usage for se_node_acl allocation is now within target-core code, dropping the external API callers for all fabric drivers tree-wide. There is a new conversion to RCU hlists for se_node_acl and se_portal_group LUN mappings, that turns fast-past LUN lookup into a completely lockless code-path. It also removes the original hard-coded limitation of 256 LUNs per fabric endpoint. The configfs attributes for backends can now be shared between core and driver code, allowing existing drivers to use common code while still allowing flexibility for new backend provided attributes. The highlights include: - Merge sbc_verify_dif_* into common code (sagi) - Remove iscsi-target support for obsolete IFMarker/OFMarker (Christophe Vu-Brugier) - Add bidi support in target/user backend (ilias + vangelis + agover) - Move se_node_acl allocation into target-core code (hch) - Add crc_t10dif_update common helper (akinobu + mkp) - Handle target-core odd SGL mapping for data transfer memory (akinobu) - Move transport ID handling into target-core (hch) - Move task tag into struct se_cmd + support 64-bit tags (bart) - Convert se_node_acl->device_list[] to RCU hlist (nab + hch + paulmck) - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch + paulmck) - Simplify target backend driver registration (hch) - Consolidate + simplify target backend attribute implementations (hch + nab) - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch) - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab) - Drop unnecessary core_tpg_register TFO parameter (nab) - Use 64-bit LUNs tree-wide (hannes) - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (76 commits) target: Bump core version to v5.0 target: remove target_core_configfs.h target: remove unused TARGET_CORE_CONFIG_ROOT define target: consolidate version defines target: implement WRITE_SAME with UNMAP bit using ->execute_unmap target: simplify UNMAP handling target: replace se_cmd->execute_rw with a protocol_data field target/user: Fix inconsistent kmap_atomic/kunmap_atomic target: Send UA when changing LUN inventory target: Send UA upon LUN RESET tmr completion target: Send UA on ALUA target port group change target: Convert se_lun->lun_deve_lock to normal spinlock target: use 'se_dev_entry' when allocating UAs target: Remove 'ua_nacl' pointer from se_ua structure target_core_alua: Correct UA handling when switching states xen-scsiback: Fix compile warning for 64-bit LUN target: Remove TARGET_MAX_LUNS_PER_TRANSPORT target: use 64-bit LUNs target: Drop duplicate + unused se_dev_check_wce target: Drop unnecessary core_tpg_register TFO parameter ... -
