2019-02-18media: vicodec: Add a flag for I-frames in fwht headerDafna Hirschfeld
Add a flag 'FWHT_FL_I_FRAME' that indicates that this is an I-frame. This requires incrementing to version 3 This flag is needed for the upcoming stateless FWHT decoder since it has to know if an encoded frame is an I or a P frame.

2019-02-18media: exynos4-is: remove redundant check on typeColin Ian King
The check to see if type is V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE is redundant as this has been already checked at the start of the function and if it's not that value then -ENOSYS is returned. Hence the sprintf can be replaced by a simpler string copy.

2019-02-18media: v4l2-mem2mem: Correct return type for mem2mem buffer helpersEzequiel Garcia
This commit changes the return type of mem2mem buffer handling API. Namely, these functions: v4l2_m2m_next_buf v4l2_m2m_last_buf v4l2_m2m_buf_remove v4l2_m2m_next_src_buf v4l2_m2m_next_dst_buf v4l2_m2m_last_src_buf v4l2_m2m_last_dst_buf v4l2_m2m_src_buf_remove v4l2_m2m_dst_buf_remove which currently return void pointer.

2019-02-18media: sun6i: Add support for JPEG media bus formatChen-Yu Tsai
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.

2019-02-18media: sun6i: Fix CSI regmap's max_registerChen-Yu Tsai
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.

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.

For the root node on SUN DT, we need to retrieve the 'name' property as it is the rare case where the 'name' property and node name differ.

2019-02-18media: v4l: Add 32-bit packed YUV formatsVivek Kasireddy
The formats added in this patch include: V4L2_PIX_FMT_AYUV32 V4L2_PIX_FMT_XYUV32 V4L2_PIX_FMT_VUYA32 V4L2_PIX_FMT_VUYX32 These formats enable the trasmission of alpha channel data to other drivers and userspace applications in addition to YUV data. For example, buffers generated by drivers in one of these formats can be used by the Weston compositor to display as a texture or flipped directly onto the overlay planes with the help of a DRM driver.

2019-02-18mt76: fix corrupted software generated tx CCMP PNFelix Fietkau
Since ccmp_pn is u8 *, the second half needs to start at array index 4 instead of 0. Fixes a connection stall after a certain amount of traffic Fixes: 23405236460b9 ("mt76: fix transmission of encrypted management frames") Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76: fix tx status timeout processingFelix Fietkau
Remove bogus check for MT_PACKET_ID_NO_ACK in mt76_tx_status_skb_get, which is already handled in callers and turns timeout calls into no-ops Do not clean up pending status items on reordering of tx status information if the timeout is not reached yet Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76: Use the correct hweight8() functionBen Hutchings
mt76_init_stream_cap() and mt76_get_txpower() call __sw_hweight8() directly, but that's only defined if CONFIG_GENERIC_HWEIGHT is enabled. The function that works on all architectures is hweight8(). Fixes: 551e1ef4d291 ("mt76: add mt76_init_stream_cap routine") Fixes: 9313faacbb4e ("mt76: move mt76x02_get_txpower to mt76 core") Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Felix Fietkau <nbd@nbd.name>
