1.2.0 Handle creation of arrays that contain failed devices.
1.3.0 Added support for RAID 10
1.3.1 Allow device replacement/rebuild for RAID 10
+1.3.2 Fix/improve redundancy checking for RAID10
Required properties for pin configuration node:
- atmel,pins: 4 integers array, represents a group of pins mux and config
setting. The format is atmel,pins = <PIN_BANK PIN_BANK_NUM PERIPH CONFIG>.
- The PERIPH 0 means gpio.
+ The PERIPH 0 means gpio, PERIPH 1 is periph A, PERIPH 2 is periph B...
+ PIN_BANK 0 is pioA, PIN_BANK 1 is pioB...
Bits used for CONFIG:
PULL_UP (1 << 0): indicate this pin need a pull up.
