This removes s_parm abuse in using driver specific values in v4l2_streamparm.capture.capturemode. The drivers already support [gs]_frame_interval so removing support for [gs]_parm is enough.

flags the device exposes for UVC controls. This allows the device to define which property flags are set. Since some cameras offer auto-adjustments for properties (e.g. auto-gain), the values of other properties (e.g. gain) can change in the camera. Examining the flags ensures that the driver is aware of such properties.

To avoid mixing multiple coding styles in the driver, use parentheses around all sizeof operands. While at it replace a kmalloc() with a kmalloc_array() to silence a checkpatch warning triggered by this patch.

Older Kernels use a struct for ktime_t, which requires the conversion function ktime_to_ns to be used on some places. With this patch it will compile now also for older Kernel versions.

Since the current code does ioremap the page address, if the offset > 0, it does not do ioremap the last page and results in kernel panic. This fixes to pass the size + offset to ioremap so that ioremap can map correct area. Also, this uses __pfn_to_phys() to get the physical address of given PFN.

soc_camera dependencies Remove soc_camera framework dependencies from tw9910 sensor driver. - Handle clock and gpios - Register async subdevice - Remove soc_camera specific g/s_mbus_config operations - Add kernel doc to driver interface header file - Adjust build system This commit does not remove the original soc_camera based driver as long as other platforms depends on soc_camera-based CEU driver.

Move Migo-R platform to use the v4l2 renesas-ceu camera driver interface and get rid of soc_camera defined components used to register sensor drivers and of platform specific enable/disable routines. Register clock source and GPIOs for sensor drivers, so they can use clock and gpio APIs. Also, memory for CEU video buffers is now reserved with membocks APIs, and need to be declared as dma_coherent during machine initialization to remove that architecture specific part from CEU driver.
