Subject: [PATCH 358/454] spi: Make GPIO CSs honour the SPI_NO_CS flag
|
|
|
|
The SPI configuration state includes an SPI_NO_CS flag that disables
|
|
all CS line manipulation, for applications that want to manage their
|
|
own chip selects. However, this flag is ignored by the GPIO CS code
|
|
in the SPI framework.
|
|
|
|
Correct this omission with a trivial patch.
|
|
