2019-05-29media: omap3isp: Don't rely on devm for memory resource managementSakari Ailus1-4/+7
devm functions are fine for managing resources that are directly related to the device at hand and that have no other dependencies. However, a process holding a file handle to a device created by a driver for a device may result in the file handle left behind after the device is long gone. This will result in accessing released (and potentially reallocated) memory. Instead, manage the memory resources in the driver. Releasing the resources can be later on bound to e.g. by releasing a reference.

2018-05-09media: omap3isp: support 64-bit version of omap3isp_stat_dataArnd Bergmann1-0/+2
C libraries with 64-bit time_t use an incompatible format for struct omap3isp_stat_data. This changes the kernel code to support either version, by moving over the normal handling to the 64-bit variant, and adding compatiblity code to handle the old binary format with the existing ioctl command code. Fortunately, the command code includes the size of the structure, so the difference gets handled automatically. In the process of eliminating the references to 'struct timeval' from the kernel, I also change the way the timestamp is generated internally, basically by open-coding the v4l2_get_timestamp() call.

2016-11-16[media] v4l: omap3isp: Use dma_request_chan_by_mask() to request the DMA channelPeter Ujfalusi1-13/+15
When requesting the DMA channel it was mandatory that we do not have DMA resource nor valid DMA channel via DT. In this case the dma_request_slave_channel_compat() would fall back and request any channel with SW trigger. The same can be achieved with the dma_request_chan_by_mask() without the misleading use of the DMAengine API - implying that the omap3isp does need to have DMA resource or valid dma binding in DT.

Feature-wise the driver has lost the ability to get notified of DMA transfers failure through the completion handler, as the DMA engine API doesn't expose that status information.

This patch fixes a bug which causes all histogram regions to start in the top left corner of the image. The histogram region coordinates are 16 bit values which share a 32 bit register. The bug is due to the region end value assignments overwriting the region start values with zero.
