Problems with DragonBoard-410c/HardwareDocs/HardwareUserManual.md PMIC GPIO #229

Closed sjfricke closed 5 years ago

In the Hardward User Manual It says the in USB Host Ports that it uses USB_SW_SEL_PM, GPIO_4. It also says in Four User LEDs that The other two User LEDs are driven by the PMIC via PM GPIO_1 and PM GPIO_2.

According to the Qualcomm Developer PDF it should be:

PM_GPIO_01 == USB_HUB_RESET_N
PM_GPIO_02 == USB_SW_SEL
PM_GPIO_03 == USB_LED_3_CTRL
PM_GPIO_04 == USB_LED_4_CTRL

@sjfricke Looks like the QDN document is wrong! According to schematics, following is the pin mapping:

PM_GPIO_1 - USR_LED_3_CTRL
PM_GPIO_2 - USR_LED_4_CTRL
PM_GPIO_3 - USB_HUB_RESET_N_PM
PM_GPIO_4 - USB_SW_SEL_PM

Above holds true for Hardware User Manual.

@ndechesne your views?

Thanks for spotting!

ndechesne commented 5 years ago

sorry about the delay.. the schematics (and the DTS in upstream kernel) are correct.

No changes necessary. Closing issue. Thanks!
