Previously, vblank range given to user was too big, falling outside of permissible range for a given resolution. Sometimes, too low vblank resulted in errors. Now, limit vblank to only permissible range for a given resolution. This change limits lower-bounds of vblank, doesn't affect upper bounds. Signed-off-by:

The et8ek8 driver combines I²C register writes to a single array that it passes to i2c_transfer(). The maximum number of writes is 48 at once, decrease it to 8 and make more transfers if needed. Signed-off-by:

The v4l2_subdev_ops structure is only passed as the third argument of v4l2_i2c_subdev_init, which is const, so the v4l2_subdev_ops structure can be const as well. The other structures are only stored in the v4l2_subdev_ops structure, all the fields of which are const, so these structures can also be const. Done with the help of Coccinelle. Signed-off-by:

Previously, pixel-rate/(pixels-per-line * lines-per-frame) was yielding incorrect frame timing for the user. OV sensor is using internal timing and this requires conversion (internal timing -> PPL) for correct HBLANK calculation. Now, change pixels-per-line domain from internal sensor clock to pixels domain. Set HBLANK read-only because fixed PPL is used for all resolutions. And, use more accurate link-frequency 422.4MHz instead of rounding down to 420MHz. Signed-off-by:

The first argument of function snd_ctl_new1 is of type const struct snd_kcontrol_new * but in this file the variable is passed by value to this function. This generated ""incompatible type for argument" error. So, pass the variable by reference. Signed-off-by:

struct v4l2_subdev.host_priv is intended to be used by another driver. This is hardly good design but back in the days of platform data was a quick hack to get things done. As the sub-device specific bus information can be stored to the ISP driver specific struct allocated along with v4l2_async_subdev, keep the information there and only there. Signed-off-by:

The CSI PHY is associated with a CSI receiver. The code assumes this receiver is a CSI2 module and relies on the CSI2 module object heavily to access the ISP or pipeline objects. However, the receiver could also be a CSI1/CCP2 module. Pass a new CSI receiver entity pointer to the CSI PHY acquire function, and replace all hardcoded usage of the CSI2 module with that CSI receiver entity. Signed-off-by:

The free_irq() function could be called from interrupt context, which is invalid. Move this to the thread. In the interrupt handler we just request that the thread disables the irq. This is done through an atomic so we don't need to add any spinlocks. Signed-off-by:

The CEC_EVENT_PIN_LOW/HIGH defines and the cec_queue_pin_event() function did not specify that these were about CEC pin events. Since in the future there will also be HPD pin events it is wise to rename the event defines and function to CEC_EVENT_PIN_CEC_LOW/HIGH and cec_queue_pin_cec_event() now before these become part of the ABI.

Section 9.2.6.4 of USB 2.0/3.x specification describes that "device must be able to return the first data packet to host within 500 ms of receipt of the request. For subsequent data packet, if any, the device must be able to return them within 500 ms". This is to fix incorrect timeout and change it from 300 ms to 500 ms to meet the timing specified by specification for Get Request. Signed-off-by:
