util/intelp2m: Update output information format in the comments Update the information format in the comments above the macros in the generated gpio.h file: PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE, DISPUPD), /* LPSS_UART0_TXD */ -->(i) /* GPIO_39 - LPSS_UART0_TXD */ --> (ii) /* DW0: 0x44000400, DW1: 0x00003100 */ --> (ii) /* DW0 : PAD_TRIG(OFF) - IGNORED */ --> (iii) /* _PAD_CFG_STRUCT(GPIO_39, PAD_FUNC(NF1) | PAD_RESET(DEEP) | PAD_TRIG(OFF), PAD_PULL(UP_20K) | PAD_IOSTERM(DISPUPD)), */ --> (iiii) PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE, DISPUPD), Also, in the case of field macros: /* GPIO_39 - LPSS_UART0_TXD */ --> (ii) /* DW0: 0x44000400, DW1: 0x00003100 */ --> (ii) /* DW0 : PAD_TRIG(OFF) - IGNORED */ --> (iii) /* PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE, DISPUPD), */ --> (iiii) PAD_CFG_STRUCT(GPIO_39, PAD_FUNC(NF1) | PAD_RESET(DEEP) | PAD_TRIG(OFF), PAD_PULL(UP_20K) | PAD_IOSTERM(DISPUPD)), By default, if do not use the -i... option, then additional information in comments will not be generated.
