> From: Dinesh Maniyam <[email protected]>

> This patch is to set spi-max-freq to 50Mhz. This will add support to the

> to set the operation speed according to the slave device up to 50Mhz.
> Without this node, the driver just can adjust the operation speed to the
> default speed which is far below the best operation speed of the SPI slave
> device.
