Hi Caesar,

Am Mittwoch, 16. Dezember 2015, 16:27:19 schrieb Caesar Wang:
Update the core dts for rk3036 SoCs.

1) Add the display (lcdc, hdmi, vop...) device node.
2) modify the i2s name to i2s0 and i2s1.
   Although there is only one i2s IP inside the rk3036,
   we need use all of the gpios of i2s0 and i2s1.
   So, we add the i2s1 IP is the same with i2s0 to support the
   different gpios.
3) Add sdio for wifi module, sdmmc for sd card.
if you need a list to describe changes, it is a good indication that this 
needs to be split into separate patches.

same as above - no driver. With the addition, that the usbphy on rk3036, 
rk3368 (and probably more) is a new IP (Innosilicon it seems instead of the 
DWC picophy) and includes a whole additional set of function registers 
(GRF_USBPHYx_CONy...) to control the phy block, so this should definitly also 
be a separate driver.

Especially also as I'm not yet clear on the clock situation.

On rk3036 sclk_otgphy0 seems to be supplying the phyblock directly (and both 
the HOST and OTG phys).
On rk3228 the phy block has two supplying clocks for 1 OTG and 3 HOSTs (and I 
haven't been able to figure out which is supplying which usb block yet)

etc.

That looks wrong. If I understand you correctly, there is one i2s block (which 
I found in the manual) but you can decide which of two pingroups it should use 
(either what you call is20 or i2s1), right?

In this case the soc-level dtsi should only declare the groups below, but not 
assign any of them and leave that to the board-level dts file to select the 
correct one (Instead of declaring a second i2s host, if there isn't any).
