AM3359: Missing MCSPI_WAKEUPENABLE register in McSpi documentation

Martin Kaul

Part Number: AM3359

Hi,

Looking into the Linux OMAP2 McSPI sourcecode (spi-omap2-mcspi.c) I find a register OMAP2_MCSPI_WAKEUPENABLE at SPI Base-Address offset 120h that is not described in the Technical Reference Manual (SPRUH73Q) chapter 24.4.1

Is there a reason not to document this register? What is the meaning of this register?

Best regards

The MCSPI_WAKEUPENABLE register is used to enable/disable wake-up functionality in slave mode when an active control signal is detected on the spim_cs line.

This register is not documented in the AM335x TRM as the feature is not supported by the AM335x family of devices - see Table 24-1 in the TRM.
