Subject: [PATCH v9 0/3] media: rockchip: Add a driver for Rockchip's camera interface
Hello everyone,
V9 for basic support of the Video Input Processor found on the Rockchip PX30 SoC
The v6 is based on the v5 of the series introducing the driver: sent 29 Dec 2020 [1]
Most of this driver was written following the BSP driver from rockchip,
removing the parts that either didn't fit correctly the guidelines, or
that couldn't be tested.
In the BSP, this driver is known as the "cif" driver, but this was
renamed to "vip" to better fit the controller denomination in the
datasheet.
This version of the driver supports ONLY the parallel interface BT656
and was tested/implemented using an SDTV video decoder
media_tree, base-commit: 94e27fbeca27d8c772fc2bc807730aaee5886055
V8 => V9:
cif/capture.c cif/dev.c cif/dev.h:
as suggested by Paul:
- changed the name from "vip" back to "cif"
- removed the scratch buffer and added frame dropping
- removed mplane, only single plane formats are supported anyway
- adjusted the Kconfig
- added the match_data to the stream struct
- some cosmetics, and error return codes changes
as suggested by Michael:
- changed the writel and readl helpers to be inline functions and
changed the name
- fixed typos in the commit message
- changed the cif_device struct element "sensor" to "remote"
rockchip,rk3066-cif.yaml:
- changed the compatible rockchip,px30-vip to rockchip,rk3066-cif:
rk3066 is the earliest Rockchip SoC that uses cif and it is the
first model starting the RK30 lineup.
- changed the node name to video-capture
- adjusted the description
V7 => V8:
vip/capture.c:
- fixed a warning: unused variable reported by the kernel test robot
V6 => V7:
vip/capture.c vip/dev.c vip/dev.h
- renamed all struct rk_vip_dev dev => struct rk_vip_dev vip_dev
- added some error when rk_vip_get_buffer() returns NULL
- removed a WARN_ON
- made the irq NOT shared
- dropped of_match_ptr
- added the rk_vip_get_resource() function
rockchip,px30-vip.yaml:
- changed filename to match the compatible
- dropped the mention of the other rockchip SoC in the dt-binding
description and added a more detailed description of VIP
- removed unused labels in the example
V5[1] => V6:
vip/capture.c vip/dev.c vip/dev.h
- added a video g_input_status subdev call, V4L2_IN_CAP_STD and the
supported stds in rk_vip_enum_input callback
- added rk_vip_g_std, rk_vip_s_std and rk_vip_querystd callbacks
- added the supported video_device->tvnorms
- s_std will now update the format as this depends on the standard
NTSC/PAL (as suggested by Hans in [1])
- removed STD_ATSC
- moved the colorimetry information to come from the subdev
- removed the core s_power subdev calls
- dropped cropping in rk_vip_stream struct
rockchip-vip.yaml:
- fixed a mistake in the name of third clock plckin -> plck
- changed the reg maxItems 2 -> 1
