3dae1c0919 drm/arm/malidp: Implemented the size validation for AFBC framebuffers
AFBC buffers include additional metadata which increases the required
allocation size. Implement the appropriate size validation and sanity
checking for AFBC buffers.
Added malidp specific function for framebuffer creation. This checks
if the framebuffer has AFBC modifiers and if so, it verifies the
necessary constraints on the size, alignment, offsets and pitch.

Changes from v2:
- Replaced DRM_ERROR() with DRM_DEBUG_KMS() in
malidp_verify_afbc_framebuffer_caps() and malidp_verify_afbc_framebuffer_size()

The reason for this is that drm_fbdev_cma_init() removes the drm_client
when fbdev registration fails, but it doesn't remove the client from the
drm_device client list. So the client list now has a pointer that points
into the unknown and we have a 'use after free' situation.

Split drm_client_new() into drm_client_init() and drm_client_add() to fix
removal in the error path.

175c98aa26 irqchip/irq-mvebu-icu: Add support for System Error Interrupts (SEI)

let's add SEI support to the ICU driver.

type of interrupts.

Each interrupt domain is a tree domain to avoid allocation the 207

61ce8d8d8a irqchip/irq-mvebu-sei: Add new driver for Marvell SEI
This is a cascaded interrupt controller in the AP806 GIC that collapses
SEIs (System Error Interrupt) coming from the AP and the CPs (through
the ICU).

The SEI handles up to 64 interrupts. The first 21 interrupts are wired
from the AP. The next 43 interrupts are from the CPs and are triggered
through MSI messages. To handle this complexity, the driver has to
declare to the upper layer: one IRQ domain for the wired interrupts,
one IRQ domain for the MSIs; and acts as a MSI controller ('parent')
by declaring an MSI domain.

4f4c867c91 irqchip/irq-mvebu-icu: Support ICU subnodes
The ICU can handle several type of interrupt, each of them being handled
differently on AP side. On CP side, the ICU should be able to make the
distinction between each interrupt group by pointing to the right parent.

This is done through the introduction of new bindings, presenting the ICU
node as the parent of multiple ICU sub-nodes, each of them being an
interrupt type with a different interrupt parent. ICU interrupt 'clients'
now directly point to the right sub-node, avoiding the need for the extra
ICU_GRP_* parameter.

ICU subnodes are probed automatically with devm_platform_populate(). If
the node as no child, the probe function for NSRs will still be called
'manually' in order to preserve backward compatibility with DT using the
old binding.

00885a77c8 irqchip/irq-mvebu-icu: Disociate ICU and NSR
NSR (non-secure interrupts) are handled in the ICU driver like if there
was only this type of interrupt in the ICU. Change this behavior to
prepare the introduction of SEI (System Error Interrupts) support by
moving the NSR code in a separate function. This is done under the form
of a 'probe' function to ease future migration to NSR/SEI being platform
devices part of the ICU. The 'icu' structure is passed as driver data
and not as a parameter for the same reason.

1f23a56a46 drm/malidp: Enable MMU prefetch on Mali-DP650
Mali-DP650 supports warming up the SMMU translations, by sending
requsts to the SMMU before a buffer is read.

There are two modes supported:

- PARTIAL: could be enabled when the buffer is composed of 4K or 64K
  pages, the display hardware will send a configurable number of
  requests before the actual reading.

- FULL: could be enabled when the buffer is composed of 1M or 2M
  pages, the display hardware will send requests before reading for
  all pages composing the buffer.

This patch adds a mechanism for detecting the page size and set the
MMU prefetch mode if possible.

Changes since v1:
 - For imported buffers use the already populated
   drm_gem_cma_object.sgt instead of calling
   driver.gem_prime_get_sg_table, which works just for buffers
   allocated through the gem_cma API.

2b4dab69dc irqchip/irq-mvebu-icu: Fix wrong private data retrieval
The irq_domain structure has an host_data pointer that just stores
private data. It is meant to not be touched by the IRQ core. However,
when it comes to MSI, the MSI layer adds its own private data there
with a structure that also has a host_data pointer.

Because this IRQ domain is an MSI domain, to access private data we
should do a d->host_data->host_data, also wrapped as
'platform_msi_get_host_data()'.

This bug was lying there silently because the 'icu' structure retrieved
this way was just called by dev_err(), only producing a
'(NULL device *):' output on the console.

do the plane_check. Mali DP supports blending the current plane
with the background either based on the pixel alpha blending
mode or by using the layer's alpha value, but not both at the
same time. If both case, plane_check will return failed.

is the 0xffff, set the pixel blending bits accordingly. If not
we'd set ALPHA bit as zero and layer alpha value.

b11507815d drm/malidp: Fix writeback in NV12
When we want to writeback to memory in NV12 format we need to program
the RGB2YUV coefficients. Currently, we don't program the coefficients
and NV12 doesn't work at all.

This patchset fixes that by programming a sane default(bt709, limited
range) as rgb2yuv coefficients.

In the long run, probably we need to think of a way for userspace to
be able to program that, but for now I think this is better than not
working at all or not advertising NV12 as a supported format for
memwrite.

Changes since v1:
 - Write the rgb2yuv coefficients only once, since we don't change
   them at all, just write them the first time NV12 is programmed,
   suggested by Brian Starkey, here [1]

by calling drm_crtc_vblank_on/off/reset which together with
drm_vblank_get have some magic that prevents calling drm_vblank_enable
when crtc is off.

b208152556 drm/i915: Add plane alpha blending support, v2.
Add plane alpha blending support with the different blend modes.
This has been tested on a icl to show the correct results,
on earlier platforms small rounding errors cause issues. But this
already happens case with fully transparant or fully opaque RGB8888
fb's.

The recommended HW workaround is to disable alpha blending when the
plane alpha is 0 (transparant, hide plane) or 0xff (opaque, disable blending).
This is easy to implement on any platform, so just do that.

The tests for userspace are also available, and pass on gen11.

Changes since v1:
- Change mistaken < 0xff0 to 0xff00.
- Only set PLANE_KEYMSK_ALPHA_ENABLE when plane alpha < 0xff00, ignore blend mode.
- Rework disabling FBC when per pixel alpha is used.

1f83515beb genirq/msi: Allow creation of a tree-based irqdomain for platform-msi
platform_msi_create_device_domain() always creates a revmap-based
irqdomain, which has the drawback of requiring the number of MSIs
that can be allocated ahead of time. This is not always possible,
and we sometimes need to use a tree-based irqdomain instead.

Add a new platform_msi_create_device_tree_domain() helper to
that effect.

Berlin SoC files has been moved from marvell dir to synaptics dir, but

update the dir accordingly. This patch fixes it.

From another side, new derivative SoCs from Synaptics may not be named

5e2c9f9a62 irqchip/gic-v3-its: Allow use of LPI tables in reserved memory
If the LPI tables have been reserved with the EFI reservation
mechanism, we assume that these tables are safe to use even
when we find the redistributors to have LPIs enabled at
boot time, meaning that kexec can now work with GICv3.

You're welcome.

3fb68faee8 irqchip/gic-v3-its: Register LPI tables with EFI config table
Upon enabling a redistributor, let's register the allocated tables
with the EFI table that tracks the memory reservations.

f842ca8e9c irqchip/gic-v3-its: Check that all RDs have the same property table
If booting with LPIs enabled, all the redistributors must have the
exact same property table. No ifs, no buts.

c6e2ccb66d irqchip/gic-v3-its: Use pre-programmed redistributor tables with kdump kernels
If using a kdump kernel, and that we cannot disable LPIs to install
our own tables, let's switch to using the already allocated tables.

This means that we'll change some of the initial kernel's memory,
but at least we'll be able to have LPIs in this secondary kernel.

c440a9d9d1 irqchip/gic-v3-its: Allow use of pre-programmed LPI tables
In order to cope with kexec and GICv3, let's try and spot when
we're booting with LPIs already enabled, and the tables already
programmed into the redistributors.

This code is currently guarded by a predicate that is always false,
meaning this is not functionnal just yet.

e1a2e2010b irqchip/gic-v3-its: Keep track of property table's PA and VA
We're currently only tracking the page allocated to contain the
property table by its struct page. In the future, it is going to
be convenient to track both PA and VA for that page instead. Let's
do that.
