The nokia,nvm-size property was used to tell the size of the NVM memory accessible through the sensor's register interface. However, while the size isn't directly readable through the sensor's register interface, it can be detected reading the NVM memory until the selected page is no longer available. Thus remove this property. Signed-off-by:

The interface supports probing for the NVM size but this was not implemented in the driver. Do that now. This will also make nokia,nvm-size property redundant. Signed-off-by:

The BIT macro is a better way to define register bits, for 1 << bit is risky for 32-bit registers. Also remove the definition of SMIAPP_DATA_TRANSFER_IF_1_CTRL_RD_EN which has a value of zero. Signed-off-by:

devm_regulator_get may return an error but mipi_csis_phy_init misses a check for it. This may lead to problems when regulator_set_voltage uses the unchecked pointer. This patch adds a check for devm_regulator_get to avoid potential risk. Signed-off-by:

Since kernel 4.16, i2c devices with DT compatible tag are modprobed using their DT modalias. Without this patch, if this driver is build as module it would never be autoprobed. There is no need to mask it with CONFIG_OF to allow ACPI loading, this also builds find with CONFIG_OF=n. Signed-off-by:

A hardcoded 12 MHz master clock frequency has been assumed since conversion of the driver from soc_camera sensor to a standalone V4L2 subdevice by commit 23a52386 ("media: ov6650: convert to standalone v4l2 subdevice"). Fix it. Define a static table of supported master clock rates (fix misnamed symbol while being at it), then use v4l2_clk_get/set_rate() to obtain a clock rate matching one of those supported. On success, apply respective master clock hardware divisor provided by the matching element of the table. [Sakari Ailus: Initialize xclk to NULL.] Signed-off-by:

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.

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.

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 23a52386 ("media: ov6650: convert to standalone v4l2 subdevice"), that attribute had been replaced by a constant and hardcoded to an arbitrarily chosen pixel clock limit. Drop it. Host interfaces can limit frame rate if needed by calling .s_frame_interval(). Signed-off-by:

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. Signed-off-by:

Currently the "chip found" message is shown even in the case where the I2C address is wrongly passed in the device tree, or also in the case of probe failure, which is misleading. To avoid such problem, move this message after real I2C transactions have been successfully made and we are certain that the adv7180 is really present and probed. Signed-off-by:
