2021-08-04media: venus: hfi: fix return value check in sys_get_prop_image_version()Zhen Lei1-1/+1
In case of error, the function qcom_smem_get() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

2021-08-04media: cec-pin: rename timer overrun variablesDeborah Brouwer2-12/+12
The cec pin timer overruns are measured in microseconds, but the variable names include the millisecond symbol "ms". To avoid confusion, replace "ms" with "us" in the variable names and printed status message.

The TD1997x chip retains vper, hper and hsper register values when the HDMI source is disconnected. Use a different means of checking if the link is still valid.

2021-08-04media: v4l2-dv-timings.c: fix wrong condition in two for-loopsHans Verkuil1-2/+2
These for-loops should test against v4l2_dv_timings_presets[i].bt.width, not if i < v4l2_dv_timings_presets[i].bt.width. Luckily nothing ever broke, since the smallest width is still a lot higher than the total number of presets, but it is wrong. The last item in the presets array is all 0, so the for-loop must stop when it reaches that sentinel.

2021-08-04media: imx: add a driver for i.MX8MQ mipi csi rx phy and controllerMartin Kepplinger2-0/+992
Add a driver to support the i.MX8MQ MIPI CSI receiver. The hardware side is based on https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/platform/imx8/mxc-mipi-csi2_yav.c?h=imx_5.4.70_2.3.0 It's built as part of VIDEO_IMX7_CSI because that's documented to support i.MX8M platforms. This driver adds i.MX8MQ support where currently only the i.MX8MM platform has been supported.
