da80f04792 drm/i915/tgl: Read SAGV block time from PCODE
Starting from TGL, we now need to read the SAGV block time via a PCODE
mailbox, rather than having a static value.

BSpec: 49326

v2: Fix up pcode val data type (Ville), tighten variable scope (Ville)

b068a86071 drm/i915: Move SAGV block time to dev_priv
In prep for newer platforms having more complicated ways to determine
the SAGV block time, move the variable to dev_priv, and extract the
setting to an initial setup function. While we're at it, update the if
ladder to follow the new gen -> old gen order preference, and warn on
any non-specified gen.

v2: Shorten the function name (Ville), return directly (Ville), move
sagv_block_time_us value to dev_priv (Ville)

v3: Change sagv_block_time_us to u32 (Lucas), Change fallback value to
-1 (Lucas), use intel_has_sagv for setup check rather than hand-rolling
(Lucas)

52111c4628 drm/i915/perf: Store shortcut to intel_uncore
Now that we have the engine stored in i915_perf, we have a means of
accessing intel_gt should we require it. However, we are currently only
using the intel_gt to find the right intel_uncore, so replace our
i915_perf.gt pointer with the more useful i915_perf.uncore.

7dbe8c62ce ARM: dts: Add minimal Raspberry Pi 4 support
This adds minimal support for the new Raspberry Pi 4 without the
fancy stuff like GENET, PCIe, xHCI, 40 bit DMA and V3D. The RPi 4 is
available in 3 different variants (1, 2 and 4 GB RAM), so leave the memory
size to zero and let the bootloader take care of it. The DWC2 is still
usable as peripheral via the USB-C port.

Other differences to the Raspberry Pi 3:
- additional GIC 400 Interrupt controller
- new thermal IP and HWRNG
- additional MMC interface (emmc2)
- additional UART, I2C, SPI and PWM interfaces
- clock stretching bug in I2C IP has been fixed

3ff3a712a9 media: ti-vpe: vpe: don't rely on colorspace member for conversion
Up to now VPE was relying on the colorspace value of struct v4l2_format
as an indication to perform color space conversion from YUV to RGB or
not.

Instead we should used the source/destination fourcc codes as a more
reliable indication to perform color space conversion or not.

To do so, we rework the csc module to use "struct v4l2_format *" as
parameters, and reorganize the coefficients tables in a more logical
way.

d5a897c842 media: v4l2-common: add pixel encoding support
It is often useful to figure out if a pixel_format is either YUV or RGB
especially for driver who can perform the pixel encoding conversion.

Instead of having each driver implement its own "is_this_yuv/rgb"
function based on a restricted set of pixel value, it is better to do
this in centralized manner.

We therefore add a pixel_enc member to the v4l2_format_info structure to
quickly identify the related pixel encoding.
And add helper functions to check pixel encoding.

These warnings are caused by buffers which not properly cleaned
up/release during an abort use case.

In the abort cases the VPDMA desc buffers would still be mapped and the
in-flight VB2 buffers would not be released properly causing a kernel
warning from being generated by the videobuf2-core level.

   test MMAP: FAIL

The driver is failing to update the source frame sequence number in the
vb2 buffer object. Only the destination frame sequence was being
updated.

This is only a reporting issue if the user space app actually cares
about the frame sequence number. But it is fixed nonetheless.

This failure is causd by the driver failing to handle out range

VPDMA hardware is limited to 64k line stride (16 bytes aligned, so 65520
bytes). So make sure the provided or calculated 'bytesperline' is

The default pixel format was setup as pointing to a specific offset in
the vpe_formats table assuming it was pointing to the V4L2_PIX_FMT_YUYV
entry. This became false after the addition on the NV21 format (see
above commid-id)

So instead of hard-coding an offset which might change over time we need
to use a lookup helper instead so we know the default will always be what
we intended.

v4l2-compliance fails with this message:

   warn: v4l2-test-formats.cpp(717): \
   	TRY_FMT cannot handle an invalid pixelformat.
   test VIDIOC_TRY_FMT: FAIL

This causes the following kernel panic:

Unable to handle kernel paging request at virtual address 56595561
pgd = ecd80e00
*pgd=00000000
Internal error: Oops: 205 [#1] PREEMPT SMP ARM

task: ece44d80 task.stack: ecc6e000
PC is at __vpe_try_fmt+0x18c/0x2a8 [ti_vpe]
LR is at 0x8

Because the driver fails to properly check the 'num_planes' values for
proper ranges it ends up accessing out of bound data causing the kernel
panic.

Since this driver only handle single or dual plane pixel format, make
sure the provided value does not exceed 2 planes.
