I am trying to map the RTC INT pinctrl, ie RTC INT GPIOAO.BIT7.
So from the schematics it is seen below.
RTC INT GPIOAO_7 (AV46) GPIOAO_7 (JTAG_A_TMS // TSIN_A_DIN0 //
TDMB_FS // TDMB_SLV_FS)
But the S922X datasheet this pin *AV46* shows to following settings,
AN16 DVSS AV46 GPIOAO_7 BD19 BOOT_11
>From the schematics it BOOT_11 is linked to
BOOT_11 (NAND_CE0) BD19
So can I conclude that BOOT_11 (nand_ce0_pins) pin linked to the RTC INT setting
Please can somebody help me with correct pinctrl settings.
