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 patch to gpiolib-of.c providing -EPROBE_DEFER as a hint to defer
of_get_named_gpio*() to a later probe() breaks spi-pl022.c.
This patch adjusts to this change, using -EPROBE_DEFER as indication to defer.

This patch adds the ability for the driver to control the chip select directly.
This enables independence from cs_control callbacks. Configurable via
platform_data, to be extended as DT in the following patch.

Several SPI controller drivers have defined differently named properties for
the number of chip selects. Now adding "num-cs" as a reference name for new
bindings.
