5 -------------------
7 - compatible: should be "abilis,tb10x-iomux";
8 - reg: should contain the physical address and size of the pin controller's
12 Function definitions
13 --------------------
15 Functions are defined (and referenced) by sub-nodes of the pin controller.
16 Every sub-node defines exactly one function (implying a set of pins).
17 Every function is associated to one named pin group inside the pin controller
19 controller sub-nodes.
21 Required function definition subnode properties:
22   - abilis,function: should be set to the name of the function's pin group.
25   - GPIO ports: gpioa, gpiob, gpioc, gpiod, gpioe, gpiof, gpiog,
27   - Serial TS input ports: mis0, mis1, mis2, mis3, mis4, mis5, mis6, mis7
28   - Parallel TS input ports: mip1, mip3, mip5, mip7
29   - Serial TS output ports: mos0, mos1, mos2, mos3
30   - Parallel TS output port: mop
31   - CI+ port: ciplus
32   - CableCard (Mcard) port: mcard
33   - Smart card ports: stc0, stc1
34   - UART ports: uart0, uart1
35   - SPI ports: spi1, spi3
36   - JTAG: jtag
