2019-10-24media: ov6650: Don't reapply pixel clock divisor on format changeJanusz Krzysztofik
As calculation of pixel clock hardware divisor no longer depends on mbus format specific maximum pixel clock, there is no need to reapply the divisor on format change. Drop related code from ov6650_s_fmt() helper. Since a master clock hardware divisor, so far applied only together with the pixel clock divisor in a single operation, will no longer be applied from ov6650_s_fmt(), apply it, still using a hardcoded value for now, from ov6650_prog_dflt() helper so hardware is still initialised correctly on device probe.

2019-10-24media: ov6650: Simplify clock divisor calculationJanusz Krzysztofik
As appears from an analysis of to_clkrc() helper code after its pclk_limit argument has been dropped, its result no longer depends on another argument - pclk_max. Moreover, assuming that a constant value of FRAME_RATE_MAX is always used as a denominator of the only significant argument left - a struct v4l2_fract, the result in fact depends only on the numerator value of that argument. As a further consequence, it no longer makes sense to recalculate frame intervals by converting them forth and back with a GET_CLKRC_DIV(to_clkrc(tpf)) construct. Drop use of GET_CLKRC_DIV() on results of to_clkrc() where possible - use the frame interval value directly. Furthermore, replace the to_clkrc() helper function with a simple macro and update its users to always use FRAME_RATE_MAX as frame interval denominator and pass only its numerator as an argument.

2019-10-24media: ov6650: Drop obsolete .pclk_limit attributeJanusz Krzysztofik
That attribute used to be obtained from platform data by a soc_camera host interface and passed to the sensor driver for .s_mbus_fmt() video operation callback, later reused as .set_fmt() pad operation callback, to be able to limit frame rate. The driver stored that value in its private structure for further use from .g/s_parm(), later converted to g/s_frame_interval(). On conversion of the driver from soc_camera sensor to a standalone V4L2 subdevice by commit 23a52386fabe ("media: ov6650: convert to standalone v4l2 subdevice"), that attribute had been replaced by a constant and hardcoded to an arbitrarily chosen pixel clock limit.

2019-10-24media: ov6650: Fix stored frame interval not in sync with hardwareJanusz Krzysztofik
The driver stores a frame interval value supposed to be in line with hardware state in a device private structure. Since the driver initial submission, the respective field of the structure has never been initialised on device probe. Moreover, if updated from .s_frame_interval(), a new value is stored before it is applied on hardware. If an error occurs during device update, the stored value may no longer reflect hardware state and consecutive calls to .g_frame_interval() may return incorrect information. Assuming a failed update of the device means its actual state hasn't changed, update the frame interval field of the device private structure with a new value only after it is successfully applied on hardware so it always reflects actual hardware state to the extent possible. Also, initialise the field with hardware default frame interval on device probe.

div_u64() does a 64-by-32 division, while the divisor max2175.xtal_freq is unsigned long, thus 64-bit on 64-bit platforms. Hence the proper function to call is div64_ul(). Note that this change does not have any functional impact, as the crystal frequency must be much lower than the 32-bit limit anyway. On 32-bit platforms, the generated code is the same. But at least on arm64, this saves an AND-instruction to truncate xtal_freq to 32-bit.

2019-10-01media: i2c: ov2659: Add powerdown/reset gpio handlingBenoit Parrot
On some board it is possible that the sensor 'powerdown' and or 'reset' pin might be controlled by gpio instead of being tied. To implement we add pm_runtime support which will handle the power up/down sequence when it is available otherwise the sensor will be powered on at module insertion/probe and powered off at module removal. Now originally the driver assumed that the sensor would always stay powered and keep its register setting. We cannot assume this anymore, so every time we "power up" we need to re-program the initial registers configuration first. This was previously done only at probe time.

2019-10-01media: v4l: Put camera sensor, lens and flash drivers under MEDIA_CAMERA_SUPPORTSakari Ailus
Instead of individually depending on MEDIA_CAMERA_SUPPORT (or forgetting it), put all camera sensor, lens and flash drivers under MEDIA_CAMERA_SUPPORT as a whole. The lens VCM devices didn't use to do this, but make them depend on MEDIA_CAMERA_SUPPORT as well since there's no use for these devices without that in practice.

2019-10-01media: ov6650: Fix stored crop rectangle not in sync with hardwareJanusz Krzysztofik
The driver stores crop rectangle settings supposed to be in line with hardware state in a device private structure. Since the driver initial submission, crop rectangle width and height settings are not updated correctly when rectangle offset settings are applied on hardware. If an error occurs while the device is updated, the stored settings my no longer reflect hardware state and consecutive calls to .get_selection() as well as .get/set_fmt() may return incorrect information. That in turn may affect ability of a bridge device to use correct DMA transfer settings if such incorrect informamtion on active frame format returned by .get/set_fmt() is used. Assuming a failed update of the device means its actual settings haven't changed, update crop rectangle width and height settings stored in the device private structure correctly while the rectangle offset is successfully applied on hardware so the stored values always reflect actual hardware state to the extent possible.
