* vfs: do bulk POLL* -> EPOLL* replacementLinus Torvalds2018-02-1111-24/+24
| | | | | | | | | | | | | | | | | | | | | | | This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | Blank help texts are probably either a typo, a Kconfig misunderstanding, or some kind of half-committing to adding a help text (in which case a TODO comment would be clearer, if the help text really can't be added right away).

That makes easier to document it, as we don't need to document weird senseless structs. At drivers, this makes even clearer about the match criteria.

Remove the static subdev[IMX_MEDIA_MAX_SUBDEVS] array, so that imx-media places no limits on the number of async subdevs that can be added and registered. There were two uses for 'struct imx_media_subdev'. First was to act as the async subdev list to be passed to v4l2_async_notifier_register(). Second was to aid in inheriting subdev controls to the capture devices, and this is done by creating a list of capture devices that can be reached from a subdev's source pad. So 'struct imx_media_subdev' also contained a static array of 'struct imx_media_pad' for placing the capture device lists at each pad. 'struct imx_media_subdev' has been completely removed. Instead, at async completion, allocate an array of 'struct imx_media_pad' and attach it to the subdev's host_priv pointer, in order to support subdev controls inheritance. Likewise, remove static async_ptrs[IMX_MEDIA_MAX_SUBDEVS] array. Instead, allocate a 'struct imx_media_async_subdev' when forming the async list, and add it to an asd_list list_head in imx_media_add_async_subdev(). At async completion, allocate the asd pointer list and pull the asd's off asd_list for v4l2_async_notifier_register().

These links can instead be created after all registered async subdevices have been bound in imx_media_probe_complete(). The media links between subdevices that exist in the device tree, can be created post-async completion by using v4l2_fwnode_parse_link() for each endpoint node of that subdevice. Note this approach assumes device-tree ports are equivalent to media pads (pad index equals port id), and that device-tree endpoints are equivalent to media links between pads. Because links are no longer parsed by imx_media_of_parse(), its sole function is now only to add subdevices that it encounters by walking the OF graph to the async list, so the function has been renamed imx_media_add_of_subdevs(). Similarly, the media links between the IPU-internal subdevice pads (the CSI source pads, and all pads between the vdic, ic-prp, ic-prpenc, and ic-prpvf subdevices), can be created post-async completion by looping through the subdevice's media pads and using the const internal_subdev table. Because links are no longer parsed by imx_media_add_internal_subdevs(), this function no longer needs an array of CSI subdevs to form links from. In summary, the following functions, which were used to form a list of media links at probe time, are removed: imx_media_add_pad_link() add_internal_links() of_add_pad_link() replaced by these functions, called at probe time, which only populate the async subdev list: imx_media_add_of_subdevs() imx_media_add_internal_subdevs() and these functions, called at async completion, which create the media links: imx_media_create_of_links() imx_media_create_csi_of_links() imx_media_create_internal_links() Signed-off-by: Steve Longerbeam <steve_longerbeam@mentor.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
| * | | | media: staging/imx: get CSI bus type from nearest upstream entitySteve Longerbeam2017-12-155-161/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The imx-media driver currently supports a device tree graph of limited complexity. This patch is a first step in allowing imx-media to work with more general OF graphs. The CSI subdevice assumes the originating upstream subdevice (the "sensor") is connected directly to either the CSI mux or the MIPI CSI-2 receiver. But for more complex graphs, the sensor can be distant, with possible bridge entities in between. Thus the sensor's bus type could be quite different from what is entering the CSI. For example a distant sensor could have a parallel interface, but the stream entering the i.MX is MIPI CSI-2. To remove this assumption, get the entering bus config from the entity that is directly upstream from either the CSI mux, or the CSI-2 receiver. If the CSI-2 receiver is not in the enabled pipeline, the bus type to the CSI is parallel, otherwise the CSI is receiving MIPI CSI-2. Note that we can't use the direct upstream source connected to CSI (which is either the CSI mux or the CSI-2 receiver) to determine bus type. The bus entering the CSI from the CSI-2 receiver is a 32-bit parallel bus containing the demultiplexed MIPI CSI-2 virtual channels. But the CSI and its IDMAC channels must be configured based on whether it is receiving data from the CSI-2 receiver or from the CSI mux's parallel interface pins. The function csi_get_upstream_endpoint() is used to find this endpoint. It makes use of a new utility function imx_media_find_upstream_pad(), that if given a grp_id of 0, will return the closest upstream pad from start_entity. With these changes, imx_media_find_sensor() is no longer used and is removed. As a result there is also no longer a need to identify any sensor or set the sensor subdev's group id as a method to search for it. So IMX_MEDIA_GRP_ID_SENSOR is removed. Also the video-mux group id IMX_MEDIA_GRP_ID_VIDMUX was never used so that is removed as well. The remaining IMX_MEDIA_GRP_ID_* definitions are entities internal to the i.MX. Another use of imx_media_find_sensor() in the CSI was to call the sensor's g_skip_frames op to determine if a delay was needed before enabling the CSI at stream on. If necessary this will have to be re-addressed at a later time.
