[PATCH v3 3/3] spi: core: allow creating devices without spi-max-frequency

From: Michal Suchanek
Date: Mon Jul 18 2016 - 18:36:08 EST


Since the previous patch allows creating SPI slaves without specifying
what device the CS connects to make spi-max-frequency also optional.

The spi-max-frequency is device-specific and the driver can set it
anyway.
