[PATCH 4/4] ARM: dts: at91: sam9x60_curiosity: fix eeprom compatible

[Durai Manickam KR]

The EEPROM memory on this board is microchip 24aa025e48 which is compatible with
at24c02 with a page size of 16. Fix the compatible accordingly.

Well, interesting.  I sent patches for NAND flash support on that very
board some weeks ago which were already applied to the at91 custodian
tree:

https://source.denx.de/u-boot/custodians/u-boot-at91/-/tree/next?ref_type=heads

Tom already merged that to the mainline next branch.  I suggest you
rebase on next.

Add Eugen to Cc, since he still is officially listed as maintainer of
the at91 stuff.

And please make sure that the DTS changes are syncing back from the
kernel and note what release they are part of.

Hi Alexander,

Well, it is present in custodians next branch. Only thing which is 
missed is the NAND defconfig support [PATCH 2/4]. Will send only this 
patch shortly.

Hello Durai,

Before you resend, check your config please, as in the CI loop it does 
not build as-is:

+arm-linux-gnueabi-ld.bfd: drivers/clk/at91/sam9x60.o: in function 
`sam9x60_clk_probe':
+drivers/clk/at91/sam9x60.c:595:(.text.sam9x60_clk_probe+0x500): 
undefined reference to `sam9x60_clk_register_usb'
