2022-06-27drm/ast: Fix black screen when getting out of suspendJocelyn Falempe1-0/+13
With an AST2600, the screen is garbage when going out of suspend. This is because color settings are lost, and not restored on resume.

2022-06-27media: atmel: atmel-isc-base: allow wb ctrls to be changed when isc is not configuredEugen Hristev1-4/+0
When attempting to change the white balance (WB) ctrls before starting streaming, e.g.: # v4l2-ctl -L User Controls .. blue_component_gain 0x009819c1 (int) : min=0 max=8191 step=1 default=512 value=512 flags=slider .. # v4l2-ctl --set-ctrl=blue_component_gain=500 # v4l2-ctl -L .. blue_component_gain 0x009819c1 (int) : min=0 max=8191 step=1 default=512 value=500 flags=slider .. These will not be written to the internal data struct and will not be written to the WB hardware module. Thus, after starting streaming, they will be reset to default: # v4l2-ctl -L .. blue_component_gain 0x009819c1 (int) : min=0 max=8191 step=1 default=512 value=512 flags=slider .. It does not make much sense to not be able to configure the WB controls at all times. Even if the sensor would not be RAW Bayer (and in this case the WB module is unavailable), the user could configure the ISC itself, as the ISC should not care about the sensor format. Thus, when WB module is available (if the sensor changes format e.g.) it will be already configured as be user's desires. In consequence, remove the check in isc_s_awb_ctrl that will return if ISC does not know the sensor format.

2022-06-27media: sta2x11: remove VIRT_TO_BUS dependencyArnd Bergmann1-1/+1
This driver does not use the virt_to_bus() function, though it depends on x86 specific fixups in the swiotlb code, which was last rewritten in commit e380a0394c36 ("x86/PCI: sta2x11: use default DMA address translation"). It is possible that the driver still fails to build on some architectures that are missing CONFIG_VIRT_TO_BUS, but it is always set on x86 machines with the STA2X11 platform enabled. More likely though is that it was never meant to depend on CONFIG_VIRT_TO_BUS, and the Kconfig dependency was kept from an out-of-tree version when the driver was originally merged.

2022-06-27media: hdpvr: fix error value returns in hdpvr_readNiels Dossche1-1/+1
Error return values are supposed to be negative in hdpvr_read. Most error returns are currently handled via an unsigned integer "ret". When setting a negative error value to "ret", the value actually becomes a large positive value, because "ret" is unsigned. Later on, the "ret" value is returned. But as ssize_t is a 64-bit signed number, the error return value stays a large positive integer instead of a negative integer. This can cause an error value to be interpreted as the read size, which can cause a buffer overread for applications relying on the returned size.

2022-06-27media: rkisp1: debug: Collect input status by sampling ISP_FLAGS_SHDLaurent Pinchart2-0/+63
The ISP_FLAGS_SHD register exposes the ISP parallel input signals (data and synchronization) in real time. This can help debugging when the device doesn't output any image. Sample the register 10000 times with a 1µs delay and expose the result through debugfs.

When CONFIG_DEBUGFS is disabled, there's no need to compile the debugfs support in. Make it conditional. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Dafna Hirschfeld <dafna@fastmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2022-06-27media: rkisp1: Move debugfs code to a separate fileLaurent Pinchart4-32/+57
To avoid cluttering the main rkisp1-dev.c driver file, move debugfs code to a separate source file. This prepares for extensions to the debugfs infrastructure. While at it, add a missing forward declaration for struct dentry in rkisp1-common.h to avoid depending on indirect includes.

2022-06-27media: rkisp1: resizer: Simplify register accessLaurent Pinchart3-155/+75
The registers for the mainpath and selfpath resizers are located at the same offset from the instance-specific base. Use this to simplify register access, removing the need to store per-register offsets in the rkisp1_rsz_config structure.

2022-06-27media: rkisp1: Swap value and address arguments to rkisp1_write()Laurent Pinchart6-485/+474
While writel() takes the value and address arguments in that order, most write functions (including in the regmap API) use the opposite convention. Having the value first is considered confusing, and often leads to more difficult to read code compared to the opposite convention where the write call and the register name often fit on a single line: rkisp1_write(rkisp1, RKISP1_CIF_THE_REG_NAME, complicate_calculation + for / the_register value + goes | here); Swap the arguments of the rkisp1_write() function, and use the following semantic patch to update the callers: @@ expression rkisp1, value, address; @@ - rkisp1_write(rkisp1, value, address) + rkisp1_write(rkisp1, address, value) This commit also includes a few additional line break cleanups in the rkisp1_write() calls, but no other manual change.

The BIT() macro is meant to represent a single bit. It is incorrectly used for register field values that store the value 1 in a multi-bit field. Use the usual (1 << n) construct for those. While at it, move RKISP1_CIF_MI_DMA_CTRL_READ_FMT_PACKED where it belongs with the other READ_FMT values.
