Subject: [PATCH v3 00/14] Add VOP2 support on rk3588

From: Andy Yan <[email protected]>

This patch sets aims at enable the VOP2 support on rk3588.

Main feature of VOP2 on rk3588:
Four video ports:
VP0 Max 4096x2160
VP1 Max 4096x2160
VP2 Max 4096x2160
VP3 Max 2048x1080

4 4K Cluster windows with AFBC/line RGB and AFBC-only YUV support
4 4K Esmart windows with line RGB/YUV support

The current version support all the 8 windows with all the suppported
plane format.

And we don't have a upstreamed encoder/connector(HDMI/DP) for rk3588
yet, Cristian from collabora is working on adding upstream support for
HDMI on rk3588.

My current test(1080P/4KP60) is runing with a HDMI driver pick from
downstream bsp kernel.

A branch based on linux-6.7 rc3 containing all the series and
HDMI driver(not compatible with mainline rk3568 hdmi) picked
from downstream bsp kernel is available [0].

[0]https://github.com/andyshrk/linux/tree/rk3588-vop2-hdmi-upstream-linux-6.7-rc3-2023-11-30

Changes in v3:
- split confg one patch from the vop2 driver patch
- put bool variable yuv_overlay next to other bool variable
- define macro for RK3568_OVL_CTRL__YUV_MODE
- just write RK3568_OVL_CTRL register once in function
vop2_setup_layer_mixer
- constrain properties in allOf:if:then
- some description updates
- change the subject as Krzysztof suggested, and add his ACK
- add braces for x in macro vop2_output_if_is_yyy(x)
- clear the bits of a mask before setting it in rk3588_set_intf_mux
- add more comments.
- put regs dump info in vop2_data

Changes in v2:
- fix errors when running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
- split form vop driver patch
- add rk3588_ prefix for functions which are rk3588 only
- make some calculation as fixed value and keep calculation formula as
comment
- check return value for some cru calculation functions.
- check return value for syscon_regmap_lookup_by_phandle
- add NV20/NV30 for esmart plane

Subject: [PATCH v3 02/14] Revert "drm/rockchip: vop2: Use regcache_sync() to fix suspend/resume"

From: Andy Yan <[email protected]>

This reverts commit b63a553e8f5aa6574eeb535a551817a93c426d8c.

regcache_sync will try to reload the configuration in regcache to
hardware, but the registers of 4 Cluster windows and Esmart1/2/3 on
the upcoming rk3588 can not be set successfully before internal PD
power on.

Also it's better to keep the hardware register as it is before we really
enable it.

So let's revert this version, and keep the first version:
commit afa965a45e01 ("drm/rockchip: vop2: fix suspend/resume")

Subject: [PATCH v3 03/14] drm/rockchip: vop2: set half_block_en bit in all mode

From: Andy Yan <[email protected]>

At first we thought the half_block_en bit in AFBCD_CTRL register
only work in afbc mode. But the fact is that it control the line
buffer in all mode(afbc/tile/linear), so we need configure it in
all case.

As the cluster windows of rk3568 only supports afbc format
so is therefore not affected.

Subject: [PATCH v3 05/14] drm/rockchip: vop2: Add write mask for VP config done

From: Andy Yan <[email protected]>

The write mask bit is used to make sure when writing
config done bit for one VP will not overwrite the other.

Unfortunately, the write mask bit is missing on
rk3566/8, that means when we write to these bits,
it will not take any effect.

We need this to make the vop work properly after
rk3566/8 variants.

[permalink] [raw]
Subject: [PATCH v3 11/14] drm/rockchip: vop2: Add support for rk3588

From: Andy Yan <[email protected]>

VOP2 on rk3588:

Four video ports:
VP0 Max 4096x2160
VP1 Max 4096x2160
VP2 Max 4096x2160
VP3 Max 2048x1080

4 4K Cluster windows with AFBC/line RGB and AFBC-only YUV support
4 4K Esmart windows with line RGB/YUV support

Signed-off-by: Andy Yan <[email protected]>

---

Changes in v3:
- add braces for x in macro vop2_output_if_is_yyy(x)
- clear the bits of a mask before setting it in rk3588_set_intf_mux
- add more comments.

Changes in v2:
- add rk3588_ prefix for functions which are rk3588 only
- make some calculation as fixed value and keep calculation formula as
comment
- check return value for some cru calculation functions.
- check return value for syscon_regmap_lookup_by_phandle
- add NV20/NV30 for esmart plane

Subject: [PATCH v3 04/14] drm/rockchip: vop2: clear afbc en and transform bit for cluster window at linear mode

From: Andy Yan <[email protected]>

The enable bit and transform offset of cluster windows should be
cleared when it work at linear mode, or we may have a iommu fault
issue on rk3588 which cluster windows switch between afbc and linear
mode.

As the cluster windows of rk3568 only supports afbc format
so is therefore not affected.

This enum only allows that the compatible has one element, namely one of
those listed here. In the dts though you declare
compatible = "rockchip,rk3588-iommu", "rockchip,rk3568-iommu";
meaning that the rk3588-iommu is compatible to the rk3568-iommu

I think you'll need a construct like:

properties:
compatible:
oneOf:
- enum:
- rockchip,iommu
- rockchip,rk3568-iommu
- items:
- enum:
- rockchip,rk3588-iommu
- const: rockchip,rk3568-iommu

to describe both the single-compatibles and the 2-item compatible for the
rk3588. For example pci/rockchip-dw-pcie.yaml does a similar thing already.

Some of your above descriptions end with full stop, some not. Keep one
style.

Why did you add this line? It should not be needed, if I read diff

These look the same as in top-level, so just minItems: 7

'pstate' is dereferenced before its checked being non NULL. Either the
check is unnecessary or should be before the seq_printf() call.

Did you really intend to use array index [0] here or should this rather be [i]?
If you intended to use [0] then you could move the initialization out of
the loop.

You added the number of registers to struct vop2_regs_dump, no need to

node->info_ent->data is a void pointer, no need to cast explicitly.

'n' is used only once, it might be clearer just to use the value where
needed and drop the extra variable.

There's nothing following after the ':', right? Then this should be
"VOP: disabled\n" or without the colon at all.

This code is repeated in vop2_active_regs_show() below. Maybe factor
this out to a common function?

You could rename this to include "VP" for Video Port so it's not so
easily mixed up with the defines below.

Yes, I have the same idea, maybe it's better to do the rename in a separate ?

Ah Yes, I didn't realize this is just a context line. I thought you
had added it.
