[media] s5p-fimc: Add subdev for the FIMC processing block
Add a subdev to expose the host's scaling and composition functions.
The camera frame composition onto an output buffer may be configured
through set/get_crop at FIMC.{n} source pad.
Additionally allow crop, composition and controls to be modified
during streaming. Make sure the default format is set when opening
the video capture node.
Rename struct fimc_vid_cap::fmt to more relevant 'mf' to avoid
confusion.
[media] s5p-fimc: Convert to use media pipeline operations
In the camera capture driver use fimc_pipeline_* calls provided by
the media device driver part, in place where v4l2_subdev_call() were
used. This way the capture driver don't need to differentiate between
various H/W pipeline setups, i.e. if the MIPI-CSI receiver subdev is
used or not.
Remove the sync_capture_fmt() function instead of which
fimc_pipeline_try_format() is introduced in the following patch adding
the FIMC capture subdev.
The TRY_FMT ioctl function is completed by a subsequent patch adding
the capture subdev, so the try_fmt routines can be reused in the subdev
and the video node ioctl handlers.
[media] s5p-fimc: Correct color format enumeration
Replace fimc_find_format() and find_mbus_format() with single function
that can return a pointer to the private format description based
on fourcc, media bus code or index in the table.
Create separate VIDIOC_ENUM_FMT ioctl handlers for video capture
and mem-to-mem video node. This is needed because some formats are
valid only for the video capture and some only for the mem-to-mem
video node.
[media] s5p-fimc: Convert to the new control framework
Convert the v4l controls code to use the new control framework.
fimc_ctrls_activate/deactivate functions are introduced for the
transparent DMA transfer mode (JPEG), where the rotation and flipping
controls are not supported.
The capture video node does not inherit sensors' controls when the
subdevs are configured by the user space (user_subdev_api == true).
However by default after the driver's initialization
the 'user-subdev_api' flag is false and any sensor controls will
also be available at the video node.
When the pipeline links are disconnected through the media device
the FIMC and any sensor inherited controls are destroyed and then
again created when the pipeline connection completes.
[media] s5p-fimc: Conversion to use struct v4l2_fh
This is a prerequisite for the patch converting the driver to use
the control framework. As the capture driver does not use per file
handle contexts, two separate ioctl handlers are created for it
(vidioc_try_fmt_mplane, and vidioc_g_fmt_mplane) so there is no
handlers shared between the memory-to-memory and capture video node.
Add a top level media device driver aggregating FIMC video devnodes,
MIPI-CSIS and sensor subdevs. This driver gathers all media entities
and creates the possible links between them during initialization. By
default some links will be activated to enable access to all available
sensors in the system. For example if there are sensors S0, S1 listed
in the media device platform data definition they will be by default
assigned to FIMC0, FIMC1 respectively, which in turn will corresponds
to separate /dev/video?.
There is enough FIMC H/W entities to cover all available physical camera
interfaces in the system.
The fimc media device driver is bound to the "s5p-fimc-md" platform device.
Such platform device should be created by board initialization code
and camera sensors description array need to be specified as its
platform data.
The media device driver also implements various video pipeline operations,
for enabling subdevs power, streaming, etc., which will be used by the
capture video node driver.
[media] s5p-fimc: Remove v4l2_device from video capture and m2m driver
Currently there is a v4l2_device instance being registered per each
(capture and memory-to-memory) video node created per FIMC H/W instance.
This patch is a prerequisite for using the top level v4l2_device
instantiated by the media device driver.
To retain current debug trace semantic (so it's possible to distinguish
between the capture and m2m FIMC) the video_device is used in place
of v4l2_device where appropriate.
[media] s5p-fimc: Remove sensor management code from FIMC capture driver
The sensor subdevs need to be shared between all available FIMC instances.
Remove their registration from FIMC capture driver so they can then be
registered to the media device driver.
[media] s5p-fimc: Limit number of available inputs to one
The current driver allowed camera sensors to be used only with single
FIMC H/W instance, FIMC0..FIMC2/3, designated at compile time. Remaining FIMC
entities could be used for video processing only, as mem-to-mem devices.
Required camera could be selected with S_INPUT ioctl at one devnode only.
However in that case it was not possible to use both cameras independently
at the same time, as all sensors were registered to single FIMC capture
driver. In most recent S5P SoC version there is enough FIMC H/W instances
to cover all physical camera interfaces.
Each FIMC instance exports its own video devnode. Thus we distribute
the camera sensors one per each /dev/video? by default. It will allow to
use both camera simultaneously by opening different video node.
The camera sensors at FIMC are now not selected with S_INPUT ioctl, there
is one input only available per /dev/video?.
By default a single sensor is connected at FIMC input as specified by the
media device platform data subdev description table. This assignment
can be changed at runtime through the pipeline reconfiguration at the media
device level.
There are 2 separate clock outputs available in the SoC for external sensors.
These two clocks can be shared among all FIMC entities and there is
currently no any arbitration of the clocks in the driver.
So make the capture driver not touching these clocks and let them be
be properly handled at the media device driver level, enabling proper
arbitration between FIMC entities.
[media] s5p-fimc: Remove registration of video nodes from probe()
Do not register video nodes during FIMC device probe. Also make
fimc_register_m2m_device() public for use by the media device driver.
The video nodes are to be registered during the media device driver
initialization, altogether with the subdev devnodes. The video
capture nodes need to be registered as last ones when the remaining
pipeline elements are already initialized.
Add intialization of the media entities for video capture
and mem-to-mem video nodes. The mem-to-mem entity has no pads
whereas the capture entity has single sink pad.
Also clean up the video node naming for consistency.
[media] s5p-csis: Rework the system suspend/resume helpers
Do not resume the device during system resume if it was idle
before system suspend, as this causes resume from suspend
to RAM failures on Exynos4. For this purpose runtime PM and
system sleep helpers are separated.
[media] s5p-csis: Handle all available power supplies
On the SoCs this driver is intended to support the are three separate
pins to supply the MIPI-CSIS subsystem: 1.1V or 1.2V, 1.8V and power
supply for an internal PLL.
This patch adds support for two separate voltage supplies to cover
properly board configurations where PMIC requires to configure
independently each external supply of the MIPI-CSI device. The 1.8V
and PLL supply are assigned a single "vdd18" regulator supply name
as it seems more reasonable than creating separate regulator supplies
for them.
While at here stop using the 'fixed_phy_vdd' platform_data field.
It has been introduced for boards where the MIPI-CSIS supplies are
not controllable. However it is not needed as those boards can use
the dummy regulator.
[media] s5p-fimc: Add runtime PM support in the mem-to-mem driver
Add runtime PM and system sleep support in the memory-to-memory
driver. It's required to enable the FIMC operation on Exynos4
SoCs. This patch prevents system boot failure when the driver
is compiled in, as it now tries to access its I/O memory without
first enabling the corresponding power domain.
The camera capture device suspend/resume is not fully covered,
the capture device is just powered on/off during the video
node open/close. However this enables it's normal operation
on Exynos4 SoCs.

Tuners in general convert a high frequency carrier into an Intermediate
Frequency (IF).
Digital tuners like tda18271, xc3028, etc. generally allow changing the IF
frequency, although they generally have recommented settings for the IF.
Analog tuners, have a fixed IF frequency, that depends on the physical
characteristics of some analog components.
For digital tuners, it makes sense to have ways to configure IF,
via the tuner's configuration structure, like what's done inside the
tda18271-fe maps.
The demods need to know what IF is used by the tuner, as it will need
to convert internally from IF into baseband. Currently, the bridge driver
needs to fill a per-demod configuration struct for it, or pass it via
a dvb_attach parameter.
The tda18271 datasheet recommends to use different IF's for different
delivery system types and for different bandwidths.
The DRX-K demod also needs to know the IF frequency in order to work,
just like all other demods. However, as it accepts different delivery
systems (DVB-C and DVB-T), the IF may change if the standard and/or
bandwidth is changed.
So, the usual procedure of passing it via a config struct doesn't work.
One might try to code it as two separate IF frequencies, or even as a
table in function of the delivery system and the bandwidth, but this
will be messy.
So, it is better and simpler to just add a new callback for it and
require the tuners that can be used with MFE frontends like drx-k
to implement a new callback to return the used IF.
