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")

Subject: [PATCH] spi: bcm53xx: (re)license code to the GPL v2
|
||||||
|
MIME-Version: 1.0
|
||||||
|
Content-Type: text/plain; charset=UTF-8
|
||||||
|
Content-Transfer-Encoding: 8bit
|
||||||
|
|
||||||
|
My intention was to release this code under GPL v2 license. For some
|
||||||
|
reason my initial commit 0fc6a323e191 ("spi: bcm53xx: driver for SPI
|
||||||
|
controller on Broadcom bcma SoC") totally missed licensing info.
|
||||||
|
MODULE_LICENSE was later added by Axel specifying "GNU Public License
|
||||||
|
v2 or later".
|
||||||
|
|
||||||
|
This patch clarifies situation by adding a proper header (with Copyright
|
||||||
|
line) and adjusting MODULE_LICENSE. It should be acked by every driver
|
||||||
|
contributor.
