We can just export only the first level IRQs for thermal and let the device(bxt_wcove_thermal) driver handle the second level IRQs based on thermal interrupt status register. Also, just using only the first level IRQ will eliminate the bug involved in requesting only the second level IRQ and not explicitly enable the first level IRQ. For more info on this issue please read the details at, https://lkml.org/lkml/2017/2/27/148 This patch also makes relevant change in bxt_wcove_thermal driver to use only first level PMIC thermal IRQ.
