Subject: [PATCH] spi: bcm53xx: set of_node to let DT specify device(s)

Setting of_node of master's dev seems to be a common way of letting it
|
||
|
|
work nicely with DT. This allows specifying device there instead of
|
||
|
|
hardcoding one in the driver code.
|
||
|
|
|
||
|
|
This was successfully tested with commit 1b47b98acce2 ("ARM: BCM5301X:
|
||
|
|
Add DT entry for SPI controller and NOR flash")
