* media: Revert "media: rc: some events are dropped by userspace"Sean Young2019-03-011-1/+12
| | | | | | | | | | | | | | | | | | | When an rc device is created, we do not know what key codes it will support, since a new keymap might be loaded at some later point. So, we set all keybit in the input device. The uevent for the input device includes all the key codes, of which there are now 768. This overflows the size of the uevent (UEVENT_BUFFER_SIZE) and no event is generated. Revert for now until we figure out a different solution. This reverts commit fec225a04330d0f222d24feb5bea045526031675.

* media: ov7740: fix runtime pm initializationAkinobu Mita2019-02-181-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The runtime PM of this device is enabled after v4l2_ctrl_handler_setup(), and this makes this device's runtime PM usage count a negative value. The ov7740_set_ctrl() tries to do something only if the device's runtime PM usage counter is nonzero. ov7740_set_ctrl() { if (!pm_runtime_get_if_in_use(&client->dev)) return 0; <do something>; pm_runtime_put(&client->dev); return ret; } However, the ov7740_set_ctrl() is called by v4l2_ctrl_handler_setup() while the runtime PM of this device is not yet enabled. In this case, the pm_runtime_get_if_in_use() returns -EINVAL (!= 0). Therefore we can't bail out of this function and the usage count is decreased by pm_runtime_put() without increment. This fixes this problem by enabling the runtime PM of this device before v4l2_ctrl_handler_setup() so that the ov7740_set_ctrl() is always called when the runtime PM is enabled.

* media: sun6i: Add support for JPEG media bus formatChen-Yu Tsai2019-02-183-0/+8
| | | | | | | | | | | | | | | | | The CSI controller can take raw data from the data bus and output it directly to capture buffers. This can be used to support the JPEG media bus format. While the controller can report minimum and maximum bytes per line, it has no way to report how many lines were captured in the last frame. Thus, even when the on-bus data is framed correctly, we have no way to accertain the actual amount of data captured, unless we scan the buffer for JPEG EOI markers, or sequential zeros. For now we leave bytesused alone, and leave it up to userspace applications to parse the data.

* media: sun6i: Add support for RGB565 formatsChen-Yu Tsai2019-02-183-2/+21
| | | | | | | | | | | | The CSI controller can take raw data from the data bus and output RGB565 format. The controller does not distinguish between RGB565 LE and BE. Instead this is determined by the media bus format, i.e. the format or order the sensor is sending data in.

* media: sun6i: Fix CSI regmap's max_registerChen-Yu Tsai2019-02-181-1/+1
| | | | | | | | | | | | | | | | | | | | | max_register is currently set to 0x1000. This is beyond the mapped address range of the hardware, so attempts to dump the regmap from debugfs would trigger a kernel exception. Furthermore, the useful registers only occupy a small section at the beginning of the full range. Change the value to 0x9c, the last known register on the V3s and H3. On the A31, the register range is extended to support additional capture channels. Since this is not yet supported, ignore it for now.

| | | | | | | | | | | | The uvc driver uses this function to fill in bus_info for VIDIOC_QUERYCAP, so use the same function when filling in the bus_info for the media device. The current implementation only fills in part of the info. E.g. if the full bus_info is usb-0000:01:00.0-1.4.2, then the media bus_info only has 1.4.2.

* media: sun6i: Add A64 CSI block supportJagan Teki2019-02-181-0/+11
| | | | | | | | | | | | | | | | | | CSI block in Allwinner A64 has similar features as like in H3, but the default CSI_SCLK rate cannot work properly to drive the connected sensor interface. The tested mod cock rate is 300 MHz and BSP vfe media driver is also using the same rate. Unfortunately there is no valid information about clock rate in manual or any other sources except the BSP driver. so more faith on BSP code, because same has tested in mainline. So, add support for A64 CSI block by setting updated mod clock rate.
