Should this have been

        H3SK (R-Car Starter Kit Premier, RTP0RC7795SKB00010S)
        compatible = "renesas,h3sk", "renesas,r8a7795";

instead?

Actually you are right, since Renesas naming policy changed: originally 
the assigned name was H3ULCB and all boards that I have labled as ULCB.
Now the official name is  "R-Car Starter Kit Premier" and "R-Car Starter 
Kit Pro" for H3/M3 respectively.

I've got this message from Renesas:
"

1. Official name for Gen3 low cost board

  R-Car Starter Kit Premier (We called "H3ULCB")
  R-Car Starter Kit Pro     (We called "M3ULCB")

  1-1. Please change the "M3ULCB/H3ULCB" to
       "R-Car Starter Kit Pro/Premier" on elinux.
  1-2. You DON'T have to change in source code.
       You can use ULCB in Kernel, u-boot, Yocto recipe.
  1-3. Please explain relations of "ULCB" and "Starter Kit" on elinux.
	Ex) R-Car Starter Kit Premier = H3ULCB
"


What do think about changing only first line and leave "compatible" as 
is, since h3ulcb have been using a while by different customers and 
renaming of the board name will confuse? (If we change it to 
"renesas,h3sk " then probably we need to rename the dts file 
r8a7795-h3ulcb.dts and its content)

-  - H3ULCB (RTP0RC7795SKB00010S)
+  - H3ULCB (R-Car Starter Kit Premier, RTP0RC7795SKB00010S)


And would be the best for M3 Starter Kit?
The M3 Starter Kit board labeled as "M3 StarterKit", bit it is the same 
board with different SiP.

Should it look like:

         M3ULCB (R-Car Starter Kit Pro, RTP0RC7796SKB00010S)
         compatible = "renesas,m3ulcb", "renesas,r8a7796";

or

         M3SK (R-Car Starter Kit Pro, RTP0RC7796SKB00010S)
         compatible = "renesas,m3sk", "renesas,r8a7796";

Vladimir

Re: [PATCH v3 01/12] dt: arm: shmobile: add H3ULCB board DT bindings

[Vladimir Barinov]

Hi Geert,

I've got this message from Renesas:
"

Please use H3ULCB/M3ULCB in upstream.
# I got an agreement among parties.

Board name in community: ULCB (= development code name)
Official name (product/brand name): Starter Kit Pro/Premier
"

Renaming  H3ULCB -> H3SK is not desired for Renesas.

What do you think to append the product/brand name only? :

-        H3ULCB (RTP0RC7795SKB00010S)
+       H3ULCB (R-Car Starter Kit Premier, RTP0RC7795SKB00010S)
          compatible = "renesas,h3ulcb", "renesas,r8a7795";

Regards,
Vladimir

Looks good to me.

And then we can add

        M3ULCB (R-Car Starter Kit Pro, RTP0RC7796SKB00010S)
        compatible = "renesas,m3ulcb", "renesas,r8a7796";

later.

Just wondering (it's done the same way on Salvator-X) why this is using a
GPIO interrupt, and not the dedicated AVB_PHY_INT?

    AVB_PHY_INT isn't supported by the driver yet (due to the phylib's 
misfeature which has been fixed now). I simply lack the time to work on this 
support.

The LEDs share GPIOs with the switches. Unfortunately you cannot use both
at the same time.
Perhaps we want to configure one of them for the switch, to be used as a
wakeup-source?

The same applies to Salvator-X, where we haven't wired up the LEDs nor
switches (yet).

According to the schematics, SD0_WP is wired, so I think you want to add

    wp-gpios = <&gpio3 13 GPIO_ACTIVE_HIGH>;

As you add UHS pins, I think you want to add

    sd-uhs-sdr50

too.

No, it is not wired (I look on rev0.40 and rev0.46).
The microSD card connector CN6 does not have WP on H3ULCB board.

The GPIO GP_3_13 just pulled up to 3.3V power rail.

You're right, I missed that the signal goes to D3.3V instead of to the
connector.

I think having commont for AUDIO_CLKOUT is better for user, like Salvator-X.
This "audio_clkout" is dummy. Actually, we don't need this dummy clock,
and we should use "<&rcar_sound 0>" as AUDIO_CLKOUT,
like AUDIO_CLKOUT3 as "<&rcar_sound 3>" which is used on ak4613. 
But Salvator-X and this ULCB board has very complex connection,
especially around CS2000.
This means cs2000 requests rcar_sound, and rcar_sound requests cs2000.
This audio_clkout exist to avoid probe dead-lock.
This is the reason why audio_clkout and rcar_sound::clock-frequency
has same value.
