    1 Abilis Systems TB10x pin controller
    2 ===================================
    3 
    4 Required properties
    5 -------------------
    6 
    7 - compatible: should be "abilis,tb10x-iomux";
    8 - reg: should contain the physical address and size of the pin controller's
    9   register range.
   10 
   11 
   12 Function definitions
   13 --------------------
   14 
   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
   18 driver and these names are used to associate pin group predefinitions to pin
   19 controller sub-nodes.
   20 
   21 Required function definition subnode properties:
   22   - abilis,function: should be set to the name of the function's pin group.
   23 
   24 The following pin groups are available:
   25   - GPIO ports: gpioa, gpiob, gpioc, gpiod, gpioe, gpiof, gpiog,
   26                 gpioh, gpioi, gpioj, gpiok, gpiol, gpiom, gpion
   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
   37 
   38 All other ports of the chip are not multiplexed and thus not managed by this
   39 driver.
   40 
   41 
   42 GPIO ranges definition
   43 ----------------------
   44 
   45 The named pin groups of GPIO ports can be used to define GPIO ranges as
   46 explained in Documentation/devicetree/bindings/gpio/gpio.txt.
   47
