mfd: da9052: Fix register access via SPI (72e341c4) · Commits · 戴 / test

The range of registers used by this driver exceeds that available via SPI with no paging (127), so we have to override the values from the default config which is set-up for I2C access. Also change SPI settings to match device's recommended OTP values. Signed-off-by:
