Device tree conversion of spi device vs. controller_data

[Roland Stigge <stigge@antcom.de>]

Hi,

upon DT conversion of LPC32xx, I came across the at25 spi eeprom which
needs .controller_data in struct spi_board_info for slave registration
via spi_register_board_info() (non-DT-case).

In the DT case, we need to eliminate this explicit registering call.
Therefore, I need to somehow replace the .controller_data passing in the
DT case to pass this data to the spi core. But I can't find such a
mechanism (v3.4-rc2). Is there already a concept or API that I
overlooked (please just point me to it) or what can I do to solve this?
(Looks like a general issue for spi slave registration via DT).

Thanks in advance,

Roland
