According to my QCM6490 data sheet, GPIO_50 has these functions:
* UART for qup14 (OK)
* SPI for qup14 (OK)
* SPI for qup16 (no pinctrl)

GPIO_54:
* UART qup15 (OK)
* SPI qup15 (OK)
* SPI qup14 (no pinctrl)

GPIO_55:
* UART qup15 (OK)
* SPI qup15 (OK)
* SPI qup14 (no pinctrl)

GPIO_62:
* UART qup17 (OK)
* SPI qup17 (OK)
* SPI qup16 (no pinctrl)

GPIO_63:
* UART qup16 (?)
* SPI qup16 (lane 3) (?)
* SPI qup16 (lane 5) (?)

But the GPIO_63 looks weird, is the data sheet wrong?! Where would
UART_RX of QUP1 SE7 go? Maybe it should be UART qup17 and SPI qup17 and
then SPI qup16 ??

Can somebody at Qualcomm please check 80-20659-1 Rev. AM and maybe make
the apppriate people there aware?

So yes Vladimir, you're correct. Some pinctrl definitions for those SPI
QUPs are not defined. And the datasheet seems wrong as well.

Thanks for checking!
