Part Number: TMS320DM355

Tool/software: Linux

Are there any examples of modifying the:

ARM_INTMUX - ARM Interrupt Mux Control Register

I would specifically like to set BIt 2 - INT17 to SPI1 INT0

There is no reference to that resister in arch/arm/mach-davinci/dm355.c - which is where i would have expected it....

Any help would be much appreciated!

Hi,
I am not aware of DM355, but you can refer to DM365 evm board file. Ethernet & GIO mux example "dm365evm_emac_configure" API.
You can use "davinci_cfg_reg" to program the INTMUX register.

Hope it helps :)

Thanks

Found it.

Configuration was located in: arch/arm/mach-davinci/dm355.c

INT_CFG(DM355, INT_EDMA_CC, 2, 1, 0, false)
INT_CFG(DM355, INT_EDMA_TC0_ERR, 3, 1, 0, false)
INT_CFG(DM355, INT_EDMA_TC1_ERR, 4, 1, 1, false)
