The fsl_mu.h driver need a function (static inline uint32_t MU_GetRxStatusFlags(MU_Type *base)) that get the MU RX status flags, because ipm_imx.c driver from zephyr/drivers/ipm get the RX status flags directly from MU register instead of using a function. As ipm_imx.c driver is used by multiple imx platforms that have different MU regiter map layout, each platform need to implement a 'static inline uint32_t MU_GetRxStatusFlags(MU_Type *base)' function that will be used by the ipm_imx.c in imx_mu_isr(). As imx_mu_isr() parse the RX status flags in reverse numerical order, the function need to return the RX status flags the same way. Signed-off-by: Alexandru Lastur <[email protected]>
