Hi robh, Heiko, Karthik, Helen and others,
See comments below.
Should we change Helen's patch serie a little bit to accommodate other
isp1 compatibles as well? Could you give advise here? Thanks!

We can expect a few more clocks here, so just use:
clocks:
minItems: 4
maxItems: 5
or
See question for Helen about 'pclk_isp_wrap':
clocks:
minItems: 4
maxItems: 6
From Rockchip tree:
static const char * const rk1808_isp_clks[] = {
"clk_isp",
"aclk_isp",
"hclk_isp",
"pclk_isp",
};
static const char * const rk3288_isp_clks[] = {
"clk_isp",
"aclk_isp",
"hclk_isp",
"pclk_isp_in",
"sclk_isp_jpe",
};
static const char * const rk3326_isp_clks[] = {
"clk_isp",
"aclk_isp",
"hclk_isp",
"pclk_isp",
};
static const char * const rk3368_isp_clks[] = {
"clk_isp",
"aclk_isp",
"hclk_isp",
"pclk_isp",
};
static const char * const rk3399_isp_clks[] = {
"clk_isp",
"aclk_isp",
"hclk_isp",
"aclk_isp_wrap",
"hclk_isp_wrap",
"pclk_isp_wrap"
};
Question for Helen:
Where did 'pclk_isp_wrap' go in your patch serie?

Ping, gentle reminder, do we have a recommendation on how to deal with
common driver supporting multiple SoC with different types and number
of clocks.

I was checking the clock topology, and we don't need aclk_isp and hclk_isp,
since they are parents of the "wrap" versions:
xin24m
...
pll_npll
npll
clk_isp1
clk_isp0
...
pll_cpll
...
cpll
aclk_isp1
aclk_isp1_noc
hclk_isp1
aclk_isp1_wrapper
hclk_isp1_noc
aclk_isp0
hclk_isp1_wrapper
aclk_isp0_wrapper
aclk_isp0_noc
hclk_isp0
hclk_isp0_wrapper
hclk_isp0_noc
...
pclkin_isp1_wrapper
(it is a bit weird that hclk_isp1_wrapper is a child of aclk_isp0, but this is how
is described in the SoC TRM)
I tested with only:
static const char * const rk3399_isp_clks[] = {
"clk_isp",
"aclk_isp_wrap",
"hclk_isp_wrap",
};
And it works, and it doesn't work when removing any of those.

There are two instances of the ISPv1 in the SoC (isp0 and isp1), but I can only test
isp0 on rk3399
It seems that isp1 requires pclk_isp_wrap, so we can add it as optional in the bindings (see below).

I suggest this:
clocks:
maxItems: 5
minItems: 3
description:
rk3288 clocks
ISP clock
ISP AXI clock
ISP AHB clock
ISP Pixel clock
ISP JPEG source clock
rk3399 isp0 clocks
ISP clock
ISP AXI wrapper clock
ISP AHB wrapper clock
rk3399 isp1 clocks
ISP clock
ISP AXI wrapper clock
ISP AHB wrapper clock
ISP Pixel wrapper clock
clock-names:
oneOf:
# rk3288 clocks
- items:
- const: clk_isp
- const: aclk_isp
- const: hclk_isp
- const: pclk_isp_in
- const: sclk_isp_jpe
# rk3399 isp0 clocks
- items:
- const: clk_isp
- const: aclk_isp_wrap
- const: hclk_isp_wrap
# rk3399 isp1 clocks
- items:
- const: clk_isp
- const: aclk_isp_wrap
- const: hclk_isp_wrap
- const: pclk_isp_wrap
Where "# rk3288 clocks", "# rk3399 isp0 clocks" and "# rk3399 isp1 clocks" could be
added in separated patchsets that are sure those works corretly.

Helen

FWIW this looks a little more involved than it might need to be. Ideally
we're describing things from the point of view of what inputs the device
itself wants, so the details of exactly *how* a particular SoC's clock
tree delivers them shouldn't matter to the binding, only to the actual
clock specifier values ultimately given in the DT.
From the ISP's PoV, it seems like we've got the fairly standard core
clock, ACLK and HCLK trio, plus a pixel clock for RK3288 and RK3399
ISP1, plus a JPEG source clock for RK3288. I'd be inclined to model that
as simply something like:
clock-names:
minItems: 3
maxItems: 5
items:
- const: isp
- const: aclk
- const: hclk
- const: pclk
- const: sclk_jpe
Plus then not only do we have a nice clean binding, but we avoid all the
unnecessary faff of having to deal with the "same" clocks by different
names in drivers, and sidestep the conundrum of what to do when the next
SoC comes along providing the basic ISP clocks from yet again
slightly-differently-named branches of its clock tree.

I agree this is cleaner, thanks for this suggestions, I just submitted a new version
following this https://patchwork.linuxtv.org/project/linux-media/list/?series=2844
Thanks

I like the suggestion from Robin, drivers care about board clock
categories and don't need to specify the SoC specific clocks. But it
still looks like we are putting a union of all clocks based on current
and future versions of the ISP IP in the yaml. Is it necessary to list
them out at all ? Can't driver's simply get them from the device tree
as indexes instead of names using "of_clk_get". In that case does the
dts yaml need to check for the number of clocks per SoC variant ?
