13 The AD2S1210 is a complete 10-bit to 16-bit resolution tracking
14 resolver-to-digital converter, integrating an on-board programmable

58 spi-max-frequency:
61 spi-cpha: true
63 avdd-supply:
65 A 4.75 to 5.25 V regulator that powers the Analog Supply Voltage (AVDD)
68 dvdd-supply:
70 A 4.75 to 5.25 V regulator that powers the Digital Supply Voltage (DVDD)
73 vdrive-supply:
75 A 2.3 to 5.25 V regulator that powers the Logic Power Supply Input
76 (VDrive) pin.

105 RES0 and RES1 pins are hard-wired to match the assigned-resolution-bits
110 fault-gpios:
118 adi,fixed-mode:
120 This is used to indicate the selected mode if A0 and A1 are hard-wired
121 instead of connected to GPIOS (i.e. mode-gpios is omitted).
125 assigned-resolution-bits:
129 be measured. If resolution-gpios is omitted, it is assumed that RES0 and
130 RES1 are hard-wired to match this value.
