/****************************************************************************
* Name: esp32_spi_cmddata
*
* Description:
* Some devices require and additional out-of-band bit to specify if the
* next word sent to the device is a command or data. This is typical, for
* example, in "9-bit" displays where the 9th bit is the CMD/DATA bit.
* This function provides selection of command or data.
*
* This "latches" the CMD/DATA state. It does not have to be called before
* every word is transferred; only when the CMD/DATA state changes. This
* method is required if CONFIG_SPI_CMDDATA is selected in the NuttX
* configuration
*
* Input Parameters:
* dev - Device-specific state data
* cmd - true: The following word is a command; fals: the following words
* are data.
*
* Returned Value:
* OK unless an error occurs. Then a negated errno value is returned.
