32   rohm,vout1-en-low:
34       BD9576 and BD9573 VOUT1 regulator enable state can be individually
35       controlled by a GPIO. This is dictated by state of vout1-en pin during
36       the PMIC startup. If vout1-en is LOW during PMIC startup then the VOUT1
37       enable state is controlled via this pin. Set this property if vout1-en
38       is wired to be down at PMIC start-up.
41   rohm,vout1-en-gpios:
43       GPIO specifier to specify the GPIO connected to vout1-en for vout1 ON/OFF
47   rohm,ddr-sel-low:
50       the ddr-sel pin low or high. Set this property if ddr-sel is grounded.
53   rohm,watchdog-enable-gpios:
54     description: The GPIO line used to enable the watchdog.
57   rohm,watchdog-ping-gpios:
61   rohm,hw-timeout-ms:
64       Watchdog timeout in milliseconds. If single value is given it is
65       the maximum timeout. Eg. if pinging watchdog is not done within this time
67       is configured in "window mode". Then first value is limit for short-ping
69       When two values is given the second value is the maximum timeout.
70       # (HW) minimum for short timeout is 2ms, maximum 220 ms.
71       # (HW) minimum for max timeout is 4ms, maximum 4416 ms.
