| * omap-dma/omap_vout_vrfb: fix off-by-one fi valueHans Verkuil2019-08-091-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OMAP 4 TRM specifies that when using double-index addressing the address increases by the ES plus the EI value minus 1 within a frame. When a full frame is transferred, the address increases by the ES plus the frame index (FI) value minus 1. The omap-dma code didn't account for the 'minus 1' in the FI register. To get correct addressing, add 1 to the src_icg value. This was found when testing a hacked version of the media m2m-deinterlace.c driver on a Pandaboard. The only other source that uses this feature is omap_vout_vrfb.c, and that adds a + 1 when setting the dst_icg. This is a workaround for the broken omap-dma.c behavior. So remove the workaround at the same time that we fix omap-dma.c. I tested the omap_vout driver with a Beagle XM board to check that the '+ 1' in omap_vout_vrfb.c was indeed a workaround for the omap-dma bug.

| * media: cec: add struct cec_connector_info supportDariusz Marcinkiewicz2019-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define struct cec_connector_info in media/cec.h and define CEC_CAP_CONNECTOR_INFO. In a later patch this will be moved to uapi/linux/cec.h. The CEC_CAP_CONNECTOR_INFO capability can be set by drivers, but cec_allocate_adapter() will remove it again until the public API for this can be enabled once all drm drivers wire this up correctly. Also add the cec_fill_conn_info_from_drm and cec_s_conn_info functions, which are needed by drm drivers to fill in the cec_connector info based on a drm_connector. The cec_notifier_(un)register and cec_register_cec_notifier prototypes were moved from cec-notifier.h to cec.h since cec.h no longer includes cec-notifier.h. These headers included each other before, which caused various problems. Due to these changes the seco-cec driver was changed as well: it should include cec-notifier.h, not cec.h.

| * media: coda: pad first buffer with repeated MPEG headers to fix sequence initPhilipp Zabel2019-06-244-3/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the first buffer contains only headers, the sequence initialization command fails. On CodaHx4 the buffer must be padded to at least 512 bytes, on CODA960 it seems to be enough to just repeat the sequence and extension headers (MPEG-2) or the VOS and VO headers (MPEG-4) once for for sequence initialization to succeed without further bitstream data. On CodaHx4 the headers can be repeated multiple times until the 512 byte mark is reached. A similar issue was solved for h.264 by padding with a filler NAL in commit 0eef89403ece ("[media] coda: pad first h.264 buffer to 512 bytes").

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | coda_encoder_cmd() is racy, as the last scheduled picture run worker can still be in-flight while the ENC_CMD_STOP command is issued. Depending on the exact timing the sequence numbers might already be changed, but the last buffer might not have been put on the destination queue yet. In this case the current implementation would prematurely wake the destination queue with last_buffer_dequeued=true, causing userspace to call streamoff before the last buffer is handled. Close this race window by synchronizing with the pic_run_worker before doing the sequence check.

| * media: marvell-ccic: provide a clock for the sensorLubomir Rintel2019-06-245-181/+157Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sensor needs the MCLK clock running when it's being probed. On platforms where the sensor is instantiated from a DT (MMP2) it is going to happen asynchronously. Therefore, the current modus operandi, where the bridge driver fiddles with the sensor power and clock itself is not going to fly. As the comments wisely note, this doesn't even belong there. Luckily, the ov7670 driver is already able to control its power and reset lines, we can just drop the MMP platform glue altogether. It also requests the clock via the standard clock subsystem. Good -- let's set up a clock instance so that the sensor can ask us to enable the clock. Note that this is pretty dumb at the moment: the clock is hardwired to a particular frequency and parent. It was always the case. Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | An instance of a sensor on DT-based MMP2 platform is always going to be created asynchronously. Let's move the manual device creation away from the core to the Cafe driver (used on OLPC XO-1, not present in DT) and set up appropriate async matches: I2C on Cafe, FWNODE on MMP (OLPC XO-1.75).

Allocate CEC adapters: setup of control handlers in next step requires these adapters to be allocated. 2. Setup of control handlers: This must be done prior to registering and exposing the adapters to user space to avoid a race condition. 3. Register CEC adapters: make them available to user space.
