2018-10-04media: i2c: adv748x: Register only enabled inputsJacopo Mondi
The adv748x assumes input endpoints are always enabled, and registers a subdevice for each of them when the corresponding output subdevice is registered. Fix this by conditionally registering the input subdevice only if it is actually described in device tree.

2018-10-04media: i2c: adv748x: Conditionally enable only CSI-2 outputsJacopo Mondi
The ADV748x has two CSI-2 output port and one TTL input/output port for digital video reception/transmission. The TTL digital pad is unconditionally enabled during the device reset even if not used. Same goes for the TXA and TXB CSI-2 outputs, which are enabled by the initial settings blob programmed into the chip. In order to improve power saving, do not enable unused output interfaces: keep TTL output disabled, as it is not used, and drop CSI-2 output enabling from the initial settings list, as they get conditionally enabled later.

As the driver is now allowed to probe with a single output endpoint, power management routines shall now take into account the case a CSI-2 TX is not enabled.

2018-10-04media: i2c: adv748x: Support probing a single outputJacopo Mondi
Currently the adv748x driver will fail to probe unless both of its output endpoints (TXA and TXB) are connected. Make the driver support probing provided that there is at least one input, and one output connected and protect the clean-up function from accessing un-initialized fields. Following patches will fix other uses of un-initialized TXs in the driver, such as power management functions.

2018-10-03media: v4l: i2c: Add a comment not to use static sub-device names in the futureSakari Ailus
A number of sub-device drivers used a static name for the sub-device, and thus the media entity. As the entity name must be unique within a media device, this makes it impossible to have more than one instance of each device in a media device. This is a rather severe limitation. Instead of fixing these drivers, add a comment to the drivers noting that such static names may not be used in the future. The alternative of fixing the drivers is troublesome as the entity (as well as sub-device) name is part of the uAPI. Changing that is almost certain to break something. As these devices are old but no-one has encountered a problem with the static names, leave it as-is.

2018-09-24media: cec/v4l2: move V4L2 specific CEC functions to V4L2Hans Verkuil
Several CEC functions are actually specific for use with receivers, i.e. they should be part of the V4L2 subsystem, not CEC. These functions deal with validating and modifying EDIDs for (HDMI) receivers, and they do not actually have anything to do with the CEC subsystem and whether or not CEC is enabled. The problem was that if the CEC_CORE config option was not set, then these functions would become stubs, but that's not right: they should always be valid. So replace the cec_ prefix by v4l2_ and move them to v4l2-dv-timings.c. Update all drivers that call these accordingly.

2018-09-17media: ov5640: Fix timings setup codeJacopo Mondi
As of: commit 476dec012f4c ("media: ov5640: Add horizontal and vertical totals") the timings parameters gets programmed separately from the static register values array. When changing capture mode, the vertical and horizontal totals gets inspected by the set_mode_exposure_calc() functions, and only later programmed with the new values. This means exposure, light banding filter and shutter gain are calculated using the previous timings, and are thus not correct. Fix this by programming timings right after the static register value table has been sent to the sensor in the ov5640_load_regs() function.

2018-09-17media: ov5640: Re-work MIPI startup sequenceJacopo Mondi
Rework the MIPI interface startup sequence with the following changes: - Remove MIPI bus initialization from the initial settings blob - At set_power(1) time power up MIPI Tx/Rx and set data and clock lanes in LP11 during 'sleep' and 'idle' with MIPI clock in non-continuous mode. - At s_stream time enable/disable the MIPI interface output. - Restore default settings at set_power(0) time. Before this commit the sensor MIPI interface was initialized with settings that require a start/stop sequence at power-up time in order to force lanes into LP11 state, as they were initialized in LP00 when in 'sleep mode', which is assumed to be the sensor manual definition for the D-PHY defined stop mode. The stream start/stop was performed by enabling disabling clock gating, and had the side effect to change the lanes sleep mode configuration when stream was stopped. Clock gating/ungating: - ret = ov5640_mod_reg(sensor, OV5640_REG_MIPI_CTRL00, BIT(5), - on ? 0 : BIT(5)); - if (ret) Set lanes in LP11 when in 'sleep mode': - ret = ov5640_write_reg(sensor, OV5640_REG_PAD_OUTPUT00, - on ? 0x00 : 0x70); This commit fixes an issue reported by Jagan Teki on i.MX6 platforms that prevents the host interface from powering up correctly: https://lkml.org/lkml/2018/6/1/38 It also improves MIPI capture operations stability on my testing platform where MIPI capture often failed and returned all-purple frames.

The driver registers the v4l2 subdevice before attempting to power on the chip and checking its ID. This means that a media device driver that it's waiting for this subdevice to be bound, will prematurely expose its media device node to userspace because if something goes wrong the media entity will be cleaned up again on the ov2680 probe function. This also simplifies the probe function error path since no initialization is made before attempting to enable the resources or checking the chip ID.

Since commit 9a4c7e68f7e0 ("media: tvp5150: convert register access to regmap")' the driver supports regmap. Now we can drop the handmade bit update sequence and move to the regmap provided helpers.

Regmap provides built in debugging, caching and provides dedicated accessors for bit manipulations in registers, which make the following changes a lot simpler.

2018-09-17media: tvp5150: fix switch exit in set control handlerMarco Felsch
The function only consists of a single switch case block without a default case. Unsupported control requests are indicated by the -EINVAL return code trough the last return statement at the end of the function. So exiting just the switch case block returns the -EINVAL error code but the hue control is supported and a zero should be returned instead. Replace the break by a 'return 0' to fix this behaviour.
