[PATCH 12/28] spi: dt-bindings: spi-controller: Slaves have no address cells
From: Lubomir Rintel <lkundrak@v3.sk>
Date: 2020-03-17 09:40:28
Also in:
linux-gpio, linux-i2c, linux-media, linux-mmc, linux-rtc, linux-serial, linux-spi, linux-usb, lkml
Subsystem:
open firmware and flattened device tree bindings, spi subsystem, the rest · Maintainers:
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Mark Brown, Linus Torvalds
SPI controllers in slave mode have a single child node that has no
address. Enforce #address-cells of zero instead of one.
Fixes: 0a1b929356830 ("spi: Add YAML schemas for the generic SPI options")
