When using buffers from DRM, DMA-API gives a warning about: "mapping sg segment longer than device claims to support [len=307200] [max=65536]" Add a call to vb2_dma_contig_set_max_seg_size() to tell the DMA-API about the supported segment size (which is UINT_MAX).

2024-11-07media: intel/ipu6: do not handle interrupts when device is disabledStanislaw Gruszka
Some IPU6 devices have shared interrupts. We need to handle properly case when interrupt is triggered from other device on shared irq line and IPU6 itself disabled. In such case we get 0xffffffff from ISR_STATUS register and handle all irq's cases, for what we are not not prepared and usually hang the whole system. To avoid the issue use pm_runtime_get_if_active() to check if the device is enabled and prevent suspending it when we handle irq until the end of irq. Additionally use synchronize_irq() in suspend Fixes: ab29a2478e70 ("media: intel/ipu6: add IPU6 buttress interface driver") Cc: stable@vger.kernel.org Signed-off-by: Stanislaw Gruszka <stanislaw.gruszka@linux.intel.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Tested-by: Hans de Goede <hdegoede@redhat.com> # ThinkPad X1 Yoga Gen 8, ov2740 Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2024-11-07media: i2c: st-mipid02: fix mipid02_stream_enable error handlingAlain Volmat
Following addition of cascaded s_stream call within mipid02_stream_enable and mipid02_stream_disable, the mipid02_stream_enable error handling must be fixed to simply disable the clocks & data lanes without also calling again the s_stream of the source subdev. Moreover, main control registers are reset to 0 for all cases of error within the mipid02_stream_enable even if they haven't yet been written. Correct this behavior by simply returning an error when register clear are not necessary.

The ACPI version of this driver "just works" on dts based systems with a few extensions to facilitate. - Add support for DT based probing - Add support for taking the part out of reset via a GPIO reset pin - Add in regulator bulk on/off logic for the power rails. Once done this sensor works nicely on a Qualcomm X1E80100 CRD.
