The G1 and G2 are independent and separate decoder blocks that are enabled by the vpu-blk-ctrl power-domain controller, which now has a proper driver. Because these blocks only share the power-domain, and can be independently fused out, update the bindings to support separate nodes for the G1 and G2 decoders with vpu-blk-ctrl power-domain support. The new DT + old kernel isn't a supported configuration.

This reverts commit 2c98b8a3. Reverted patch causes problems with Hauppauge WinTV dualHD as Maximilian reported [1]. Since quick solution didn't come up let's just revert it to make this device work with upstream kernels.

During encoder driver open controls are initialized via a call to v4l2_ctrl_handler_setup which returns EINVAL error for V4L2_CID_MPEG_VIDEO_H264_8X8_TRANSFORM v4l2 control. The control default value is disabled and because of firmware limitations 8x8 transform cannot be disabled for the supported HIGH and CONSTRAINED_HIGH profiles. To fix the issue change the control default value to enabled (this is fine because the firmware enables 8x8 transform for high and constrained_high profiles by default). Also, correct the checking of profile ids in s_ctrl from hfi to v4l2 ids. cc: stable@vger.kernel.org # 5.15+ Fixes: bfee75f7 ("media: venus: venc: add support for V4L2_CID_MPEG_VIDEO_H264_8X8_TRANSFORM control") Signed-off-by: Stanimir Varbanov <stanimir.varbanov@linaro.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>

VSP hardware could be used (e.g. by the bootloader) before driver load, and some interrupts could be left in enabled and pending state. In this case, setting up VSP interrupt handler without masking interrupts before causes interrupt handler to be immediately called (and crash due to null vsp->info dereference). Fix that by explicitly masking all interrupts before setting the interrupt handler. To do so, have to set the interrupt handler later, after hw revision is already detected and number of interrupts to mask gets known. Based on patch by Koji Matsuoka <koji.matsuoka.xm@renesas.com> included in the Renesas BSP kernel.

In cal_ctx_v4l2_init_formats(), devm_kzalloc() is assigned to ctx->active_fmt and there is a dereference of it after that, which could lead to NULL pointer dereference on failure of devm_kzalloc().

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Wrap the target region in struct_group(). This additionally fixes a theoretical misalignment of the copy (since the size of "buf" changes between 64-bit and 32-bit, but this is likely never built for 64-bit). FWIW, I think this code is totally broken on 64-bit (which appears to not be a "real" build configuration): it would either always fail (with an uninitialized data->buf_size) or would cause corruption in userspace due to the copy_to_user() in the call path against an uninitialized data->buf value: omap3isp_stat_request_statistics_time32(...) struct omap3isp_stat_data data64; ... omap3isp_stat_request_statistics(stat, &data64); int omap3isp_stat_request_statistics(struct ispstat *stat, struct omap3isp_stat_data *data) ... buf = isp_stat_buf_get(stat, data); static struct ispstat_buffer *isp_stat_buf_get(struct ispstat *stat, struct omap3isp_stat_data *data) ... if (buf->buf_size > data->buf_size) { ... return ERR_PTR(-EINVAL); } ... rval = copy_to_user(data->buf, buf->virt_addr, buf->buf_size); Regardless, additionally initialize data64 to be zero-filled to avoid undefined behavior.

The media bus configuration is specified through a set of flags, some of which being mutually exclusive. This doesn't scale to express more complex configurations. Improve the API by replacing the single flags field in v4l2_mbus_config by a union of v4l2_mbus_config_* structures. The flags themselves are still used in those structures, so they are kept here. Drivers are however updated to use structure fields instead of flags when already possible.

The vimc driver is used for testing purpose, and some test use cases involve sharing buffers with a consumer device. Consumers often require DMA contiguous memory, which vimc doesn't currently support. This leads in the best case to usage of bounce buffers, which is very slow, and in the worst case in a complete failure. Add support for the dma-contig allocator in vimc to support those use cases properly. The allocator is selected through a new "allocator" module parameter, which defaults to vmalloc.

The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on after having turned it off causes the CPLM3218 ambient-light-sensor on the front camera sensor's I2C bus to crash, hanging the bus. Add a DMI quirk table for systems on which to leave eldo2 on. Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor as long as the camera sensor is being used, this is what Windows seems to do as a workaround (based on analyzing the DSDT). But that is not easy to do cleanly under Linux.

On devices with 2 cameras and no _DSM / EFI-vars providing CsiPort clock info, defaulting to CsiPort 0 obviously is wrong for 1 of the 2 cameras. The Intel Cherry Trail (ISP2401) reference design combines: pmc_plt_clk_2 with CsiPort 0 pmc_plt_clk_4 with CsiPort 1 The Intel Bay Trail (ISP2400) reference design combines: pmc_plt_clk_1 with CsiPort 0 pmc_plt_clk_0 with CsiPort 1 Use this knowledge to set the default CsiPort value based on the detected CLK for the sensor.

Fix axp_v1p8_on() turning ELDO2 off at the end again by removing the bogus code which turns it off again after just having turned it on.

Testing on multiple tablet models has shown that Android always uses 1.6V for ELDO1, adjust our code to match. This also matches with how ELDO1 is used in the DSDTs on these devices, where for Cherry Trail (ISP2401) based devices ELDO1 is used for an ACPI power-resource which is named "P16P". Note on Bay Trail (ISP2400) based devices the power-resource is called "P15P", which suggests that 1.5V might be a better value there.

On devices with 2 sensors the 2 sensors may get probed simultaneously and the v1p8 and v2p8 regulators are ususally shared between the 2 sensors. This means that the probe() function of sensor 1 may end up calling gmin_v1p8_ctrl(..., false) turning the regulator off while sensor 2's probe() function still needs it to be on, causing the probe() of sensor 2 to sometimes fail. Fix this by adding an enable-count for both regulators and only disabling them again when that goes to 0. Note all this really should be converted to use the standard kernel regulator framework, I have doing this on my long term TODO list, this fix is only meant as a temporary workaround for the issue.

The second write done in axp_regulator_set() must go to the ctrl_reg which turns the various regulators on/off. This replaces the second write writing the sel_reg, which sets the voltage for the regulator, for a second time with a wrong value.

There is no irci_stable_candrpv_0415_20150521_0458 build for the isp2400/byt version of the atomisp2. There is however an irci_stable_candrpv_0415_20150423_1753 version which according to: https://github.com/intel/ProductionKernelQuilts/blob/master/uefi/cht-m1stable/patches/cam-041 Has the exact same fw ABI, so use that on the isp2400.
