On devices with 2 cameras and no _DSM / EFI-vars providing CsiPort clock info, defaulting to CsiPort 0 obviously is wrong for 1 of the 2 cameras. The Intel Cherry Trail (ISP2401) reference design combines: pmc_plt_clk_2 with CsiPort 0 pmc_plt_clk_4 with CsiPort 1 The Intel Bay Trail (ISP2400) reference design combines: pmc_plt_clk_1 with CsiPort 0 pmc_plt_clk_0 with CsiPort 1 Use this knowledge to set the default CsiPort value based on the detected CLK for the sensor.

Testing on multiple tablet models has shown that Android always uses 1.6V for ELDO1, adjust our code to match. This also matches with how ELDO1 is used in the DSDTs on these devices, where for Cherry Trail (ISP2401) based devices ELDO1 is used for an ACPI power-resource which is named "P16P". Note on Bay Trail (ISP2400) based devices the power-resource is called "P15P", which suggests that 1.5V might be a better value there.

On devices with 2 sensors the 2 sensors may get probed simultaneously and the v1p8 and v2p8 regulators are ususally shared between the 2 sensors. This means that the probe() function of sensor 1 may end up calling gmin_v1p8_ctrl(..., false) turning the regulator off while sensor 2's probe() function still needs it to be on, causing the probe() of sensor 2 to sometimes fail. Fix this by adding an enable-count for both regulators and only disabling them again when that goes to 0. Note all this really should be converted to use the standard kernel regulator framework, I have doing this on my long term TODO list, this fix is only meant as a temporary workaround for the issue.

According to v4l2-compliance utility, a video device which supports V4L2_CAP_TIMEPERFRAME via .vidioc_s_parm() operation should also support .vidioc_enum_frameintervals(). If the former is implemented via a call to v4l2_s_parm_cap() which in turn calls a subdevice .s_frame_interval() pad operation, the video device may want to implement the latter by passing frame interval enumeration requests to the subdevice .enum_frame_intervals() video operation. If that operation is not supported by the subdevice and failure is returned by the video device, the compliance test issues a warning. Implement the missing pad operation. Enumerate frame intervals possible to be set via pixel clock adjustment, as implemented by .s_frame_interval(), but not exceeding a reasonable maximum of 1 second.

According to subdevice interface specification found in V4L2 API documentation, set format pad operations should not affect image geometry set in preceding image processing steps. Unfortunately, that requirement is not respected by the driver implementation of set format as it was not the case when that code was still implementing a pair of now obsolete .s_mbus_fmt() / .try_mbus_fmt() video operations before they have been merged and reused as an implementation of .set_fmt() pad operation by commit 717fd5b4 ("[media] v4l2: replace try_mbus_fmt by set_fmt"). Exclude non-compliant crop rectangle adjustments from set format try, as well as a call to .set_selection() from set format active processing path, so only frame scaling is applied as needed and crop rectangle is no longer modified.

Try requests are now only supported by format processing pad operations implemented by the driver. The driver selection API operations currently respond to them with -EINVAL. While that is correct, it constraints video device drivers to not use subdevice cropping at all while processing user requested active frame size, otherwise their set try format results might differ from active. As a consequence, we can't fix set format pad operation as not to touch crop rectangle since that would affect users not being able to set arbitrary frame sizes. Moreover, without a working set try selection support we are not able to use pad config crop rectangle as a reference while processing set try format requests. Implement missing try selection support. Moreover, as it will be now possible to maintain the pad config crop rectangle via selection API, start using it instead of the active one as a reference while processing set try format requests. is_unscaled_ok() helper, now also called from set selection operation, has been just moved up in the source file to avoid a prototype, with no functional changes.

In case of set format active processing path the issue can be fixed easily by excluding a call to set active selection from that path. That will effectively limit frame size processing to optimal frame scaling against active crop rectangle without touching it. Users can just call set active selection themselves to obtain desired frame size. However, set format try processing path needs more work. First of all, the driver should be extended with set try selection support. Lack of it constraints video device drivers to not use subdevice cropping at all while processing user requested active frame size, otherwise their set try format results might differ from active. Next, set format try processing path should use pad config crop rectangle as a reference, not the active one as it does now. That issue can be resolved easily as soon as set try selection support is added to the driver so pad config crop rectangle can be maintained by users via selection API. Last, set format try processing path should give the same results as active in respect to active vs. pad config crop rectangle geometry. Both rectangles should be either not touched by set format (that's what we are going to achieve) or modified the same way, otherwise users won't be able to obtain equal results from both paths while iterating through set format and set selection operations in order to obtain desired frame size. We can't begin with modifying set format pad operation as not to touch crop rectangle since that depends on availability of set try selection for symmetry. Neither can we begin with adding set try selection since that in turn depends on equal handling of active and pad config crop rectangles by set format. We can either implement all required modifications in a single patch, or begin with fixing current set format try processing path to appropriately handle pad config crop rectangle. This patch implements the latter approach as believed to be more readable. Move crop rectangle adjustments code from a helper (the former implementation of .s_fmt(), now called from set format active processing path) to the body of set format pad operation function where it can be also used for processing try requests for symmetry with active ones. As the helper no longer processes frame geometry, only frame format and half scaling, simplify its API accordingly and update its users. Moreover, extract code that applies crop rectangle hardware limits (now a part of .set_selection() operation which is called from set format active processing path) to a new helper and call that helper from set format try processing path as well for symmetry with active.
