Hym8563 RTC I2C Access

#1

2 questions regarding hym8563

  1. When using the i2c1-hym8563 overlay, does this conflict with enabling rk3308-i2c1 overlay? I.e. does enabling the RTC preclude using /dev/i2c1 for other I2C devices on I2C bus #1 at the same time?

  2. does the i2c1-hym8563 overlay require the GPIO0_C1 pin be connected to the ^INT pin on the RTC or is this optional allowing that GPIO be used for other purposes?

For question one, dtbo i2c1-hym8563 and rk3308-i2c1 are not conflict when both of them are added.

For question two, /INT pin is necessary.
