I could have between 2 and 6 elements per row... to create a dual dimension array I would have to add NULL entries like that: #define MAX_TRIGGERS 6 static const void *triggers_table[][MAX_TRIGGERS] = { { TIM1_TRGO, TIM1_CH1, TIM1_CH2, TIM1_CH3, TIM1_CH4, NULL,}, { TIM2_TRGO, TIM2_CH1, TIM2_CH2, TIM2_CH3, TIM2_CH4, NULL,}, { TIM3_TRGO, TIM3_CH1, TIM3_CH2, TIM3_CH3, TIM3_CH4, NULL,}, { TIM4_TRGO, TIM4_CH1, TIM4_CH2, TIM4_CH3, TIM4_CH4, NULL,}, { TIM5_TRGO, TIM5_CH1, TIM5_CH2, TIM5_CH3, TIM5_CH4, NULL,}, { TIM6_TRGO, NULL, NULL, NULL, NULL, NULL,}, { TIM7_TRGO, NULL, NULL, NULL, NULL, NULL,}, { TIM8_TRGO, TIM8_CH1, TIM8_CH2, TIM8_CH3, TIM8_CH4, NULL,}, { TIM9_TRGO, TIM9_CH1, TIM9_CH2, NULL, NULL, NULL,}, { TIM12_TRGO, TIM12_CH1, TIM12_CH2, NULL, NULL, NULL,}, }; >> +static const char * const valids0[] = { >> + TIM5_TRGO, TIM2_TRGO, TIM4_TRGO, TIM3_TRGO, NULL, >> +}; >> + >> +static const char * const valids1[] = { >> + TIM1_TRGO, TIM8_TRGO, TIM3_TRGO, TIM4_TRGO, NULL, >> +}; >> + >> +static const char * const valids2[] = { >> + TIM1_TRGO, TIM8_TRGO, TIM5_TRGO, TIM4_TRGO, NULL, >> +}; >> + >> +static const char * const valids3[] = { >> + TIM1_TRGO, TIM2_TRGO, TIM3_TRGO, TIM8_TRGO, NULL, >> +}; >> + >> +static const char *const valids4[] = { >> + TIM2_TRGO, TIM3_TRGO, TIM4_TRGO, TIM8_TRGO, NULL, >> +}; >> + >> +static const char * const valids7[] = { >> + TIM1_TRGO, TIM2_TRGO, TIM4_TRGO, TIM5_TRGO, NULL, >> +}; >> + >> +static const char * const valids8[] = { >> + TIM2_TRGO, TIM3_TRGO, NULL, >> +}; >> + >> +static const char * const valids9[] = { >> + TIM4_TRGO, TIM5_TRGO, NULL, >> +}; >> + >> +static const void *valids_table[] = { >> + valids0, >> + valids1, >> + valids2, >> + valids3, >> + valids4, >> + NULL, >> + NULL, >> + valids7, >> + valids8, >> + valids9, >> +}; > > Same here. > > -- > Lee Jones > Linaro STMicroelectronics Landing Team Lead > Linaro.org │ Open source software for ARM SoCs > Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
