commit 5c14e51d2d7df49fe0d4e64a12c58d2542f452ff upstream. Accessing device registers seems to be not reliable, the chip revision is sometimes detected wrongly (0 instead of expected 1). Ensure that the chip reset is performed via reset GPIO and then wait for 'Device Ready' status in HW_CFG register before doing any register initializations.
