Jose Alberto Meza 65d93b4ed7 soc: arm: mchp: Allow to configure HW-controlled pins as GPIOs.
Introduce switch to allow board configuration for VCI pins to
remain HW-controled depending on the design.
Currently pins are always configured as GPIOs which is not always
desirable.

This divisor defines a ratio between processor clock (HCLK)
and master clock (MCK):
HCLK = MCK / PROC_CLK_DIV
Allowed divider values: 1, 3, 4, 16, and 48.
config SOC_MEC1501_EXT_32K
bool "Use external 32KHz clock source"
help
Use an external 32768 Hz clock source for PLL reference
clock.
Say y if you want to use an external source for the PLL
32KHz reference clock.
Say n to use the +/-2% internal silicon oscillator.

help
Choose a crystal as the external 32KHz source.
Say y if you wish to use a crystal as the external
32KHz clock source.
Saying n will select the 32KHZ_IN pin as the external
32KHz clock source.

help
Choose external 32KHz crystal connection.
Say y if the crystal is connected parallel between
the XTAL1 and XTAL pins.
Say n if the crystal is connected single ended to
the XTAL2 pin or a 32KHz square wave is on XTAL2.

Set this is if VTR3 power sourcejumper in the board is changed.

default y
help
By default these pins are not GPIOs, but HW controlled.
Set this if VCI pin block HW logic is not required in the board
design.
