I'm ok with this as long as there aren't going to be future rockchip
tweaks to the driver that will need to be separate from those already
there (ie: versioned). In the tegra driver, the product numbers serve
to represent the first product with said feature or quirk, the same
could have been done here.
However, if we know that all rockchip devices in the future will not
need to differentiate from each other, this seems fine.

eDP controller need to declare which vop provide the video source,
and it's defined in GRF registers.
But different chips have different GRF register address, so we need to
create a device data to declare the GRF messages for each chips.

I'm not sure what convention is in other drivers, but this seems less
readable to me.
I'd prefer that the magic numbers were assigned to a #define that
corresponds to a TRM name in some header. Then you have names in the
assignment instead of meaningless numbers.

I guess what irks me personally more is that it hides the write-mask as well
So I guess something like the following would also define it somewhat future-
proof
#define RK3288_GRF_SOC_CON6 0x25c
#define RK3288_EDP_LCDC_SEL BIT(5)
#define HIWORD_UPDATE(val, mask) \
(val | (mask) << 16)
static const struct rockchip_dp_chip_data rk3288_dp = {
.lcdsel_grf_reg = RK3288_GRF_SOC_CON6,
.lcdsel_big = HIWORD_UPDATE(0, RK3288_EDP_LCDC_SEL),
.lcdsel_lit = HIWORD_UPDATE(RK3288_EDP_LCDC_SEL, RK3288_EDP_LCDC_SEL),

There're an register define error in ANALOGIX_DP_PLL_REG_1 which introduced
by commit bcec20fd5ad6 ("drm: bridge: analogix/dp: add some rk3288 special
registers setting").
The PHY PLL input clock source is selected by ANALOGIX_DP_PLL_REG_1
BIT 0, not BIT 1.

As vendor document indicate, when REF_CLK bit set 0, then DP
phy's REF_CLK should switch to 24M source clock.
But due to IC PHY layout mistaken, some chips need to flip this
bit(like RK3288), and unfortunately they didn't indicate in the
DP version register. That's why we have to make this little hack.

So this is what I was talking about in my review of the first patch of
the series.
I don't personally think the dev and subdev types add any clarity
here, just more state. I'd prefer that you put the product number in
the top level devtype, and add a helper function like:
static bool is_rockchip(enum analogix_dp_devtype type) {
return type == ... || type == ...
}

RK3399 and RK3288 shared the same eDP IP controller, only some light
difference with VOP configure and GRF configure.

Changes in v3:
- Give the "rk3399-edp" a separate line for clarity in document (Tomasz, reviewed at Google Gerrit)
[https://chromium-review.googlesource.com/#/c/346314/10/Documentation/devicetree/bindings/display/rockchip/analogix_dp-rockchip.txt@5]
- Move 'output_type' setting before the return statement (Tomasz, reviewed at Google Gerrit)
[https://chromium-review.googlesource.com/#/c/346314/10/drivers/gpu/drm/rockchip/analogix_dp-rockchip.c@154]
- Add the acked flag from Mark.

As commented by Tomasz on gerrit, there is a pre-existing typo here.
Specifically "rockchip,rk3288-edp" should be "rockchip,rk3288-dp".
The typo is pre-existing so I'm not sure you would need to spin this
series to fix it, but if you were spinning it anyway it wouldn't hurt
to fix. Could also just send out a followon patch to fix this after
the series lands...

My bad, forget to fix that :(
it would be better to merge that fix into this series, would send a
follow patch soon.

This chunk seems overly complicated. I'd suggest:
s->output_type = DRM_MODE_CONNECTOR_eDP;
s->output_mode = ROCKCHIP_OUT_MODE_AAAA;
if (dp->data->chip_type == RK3399_EDP) {

I plan to return '-ENODEV' when 'drm_of_encoder_active_endpoint_id'
failed to found, but now i found there is a bug.
When the first time '.atomic_check' was called, encoder have binded to
any crtc, so the 'drm_of_encoder_active_endpoint_id' would be failed.
- If we return failure in this case, then '.atomic_check' would be
called again, then failed again, dead loop.
- If we return zero in this case and set a default
output_mode/output_type, then '.atomic_check' would be successes, then
'crtc->enable' function would use that default setting.
When framework called the 'atomic_check' again, then
'drm_of_encoder_active_endpoint_id' would return the right value, and
'crtc_state would be set rightly. *But* 'vop->enable' wouldn't take care
of those setting, caused it would return directly after detect vop have
been enabled.
This bug need patches both in connector and crtc driver, need more
discuss about this. ;)

Some boards don't need to declare a panel device node, like the
display interface is DP monitors, so it's necessary to make the
panel detect to an optional action.

Minor nit: Move of_node_put(panel_node) directly below
of_drm_find_panel to avoid duplicating it in both error and normal
paths (like you've done above).

It's better to pass the connector to platform driver in .get_modes()
callback, just like what the .get_modes() helper function designed.

Rockchip VOP couldn't output YUV video format for eDP controller, so
when driver detect connector support YUV video format, we need to hack
it down to RGB888.

Changes in v3:
- Hook the connector's color_formats in .get_modes directly. (Tomasz, reviewed at Google Gerrit)
[https://chromium-review.googlesource.com/#/c/346317/15]
- Add the acked flag from Mark.

I think this can be simplified as follows:

u32 mask = DRM_COLOR_FORMAT_YCRCB444 | DRM_COLOR_FORMAT_YCRCB422;

Hmm... I'm not sure, but it works on my several panels. I guess RGB is
more common then YUV, so if panel support YUV format, it should support
RGB888 too.

The hardware IC designed that VOP must output the RGB10 video format to
eDP contoller, and if eDP panel only support RGB8, then eDP contoller
should cut down the video data, not via VOP contoller, that's why we need
to hardcode the VOP output mode to RGA10 here.

The enum value of DP_IRQ_TYPE_HP_CABLE_IN is zero, but driver only
send drm hp event when the irq_type and the enum value is true.
if (irq_type & DP_IRQ_TYPE_HP_CABLE_IN || ...)
drm_helper_hpd_irq_event(dp->drm_dev);
So there would no drm hpd event when cable plug in, to fix that
just need to assign all hotplug enum with no-zero values.

For RK3399's GRF module, if we want to operate the graphic related grf
registers, we need to enable the pclk_vio_grf which supply power for VIO
GRF IOs, so it's better to introduce an optional grf clock in driver.

For RK3399's GRF module, if we want to operate the graphic related grf
registers, we need to enable the pclk_vio_grf which supply power for VIO
GRF IOs, so it's better to introduce an optional grf clock in driver.

The document about rockchip platform make a mistaken in available
compatible name of "rk3288-edp", we should correct it to "rk3288-dp"
which correspond to the compatible name in driver.
This mistaken was introduced in commit be91c36247089 ("dt-bindings:
add document for rockchip variant of analogix_dp").

I probably would have split into two patches so the bindings was its
own patch, but I don't think it's strictly required.
In any case, this seems good to me.

The document about rockchip platform make a mistaken in available
compatible name of "rk3288-edp", we should correct it to "rk3288-dp"
which correspond to the compatible name in driver.
This mistaken was introduced in commit be91c36247089 ("dt-bindings:
add document for rockchip variant of analogix_dp").
