Subject: [PATCH 2/2] dt-bindings: net: Convert fsl-fman to yaml
Convert fsl-fman from txt to yaml format and split it fsl,fman.yam,
fsl,fman-port.yaml, fsl-muram.yaml, fsl-mdio.yaml.
Addition changes:
fsl,fman.yaml:
- Fixed interrupts in example
- Fixed ethernet@...00 miss } in example
- ptp-timer add label in example
- Ref to new fsl,fman*.yaml
- Reorder property in example
fsl,fman-mdio:
- Add little-endian property
- Add ref to mdio.yaml
- Remove suppress-preamble
- Add #address-cells and #size-cells in example
fsl-muram.yaml:
- Add reg property

+ Software may get false read error when reading internal
+ PCS registers through MDIO. As a workaround, all internal
+ MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.
+
+ For internal PHY device on internal mdio bus, a PHY node should be created.
+ See the definition of the PHY node in booting-without-of.txt for an
+ example of how to define a PHY (Internal PHY has no interrupt line).
+ - For "fsl,fman-mdio" compatible internal mdio bus, the PHY is TBI PHY.
+ - For "fsl,fman-memac-mdio" compatible internal mdio bus, the PHY is PCS PHY.
+ The PCS PHY address should correspond to the value of the appropriate
+ MDEV_PORT.

-FMan MDIO Node
-
-DESCRIPTION
-
-The MDIO is a bus to which the PHY devices are connected.
-
-PROPERTIES
-
-- compatible
- Usage: required
- Value type: <stringlist>
- Definition: A standard property.
- Must include "fsl,fman-mdio" for 1 Gb/s MDIO from FMan v2.
- Must include "fsl,fman-xmdio" for 10 Gb/s MDIO from FMan v2.
- Must include "fsl,fman-memac-mdio" for 1/10 Gb/s MDIO from
- FMan v3.
-
-- reg
- Usage: required
- Value type: <prop-encoded-array>
- Definition: A standard property.
-
-- clocks
- Usage: optional
- Value type: <phandle>
- Definition: A reference to the input clock of the controller
- from which the MDC frequency is derived.
-
-- clock-frequency
- Usage: optional
- Value type: <u32>
- Definition: Specifies the external MDC frequency, in Hertz, to
- be used. Requires that the input clock is specified in the
- "clocks" property. See also: mdio.yaml.
-
-- suppress-preamble
- Usage: optional
- Value type: <boolean>
- Definition: Disable generation of preamble bits. See also:
- mdio.yaml.
-
-- interrupts
- Usage: required for external MDIO
- Value type: <prop-encoded-array>
- Definition: Event interrupt of external MDIO controller.
-
-- fsl,fman-internal-mdio
- Usage: required for internal MDIO
- Value type: boolean
- Definition: Fman has internal MDIO for internal PCS(Physical
- Coding Sublayer) PHYs and external MDIO for external PHYs.
- The settings and programming routines for internal/external
- MDIO are different. Must be included for internal MDIO.
-
-- fsl,erratum-a009885
- Usage: optional
- Value type: <boolean>
- Definition: Indicates the presence of the A009885
- erratum describing that the contents of MDIO_DATA may
- become corrupt unless it is read within 16 MDC cycles
- of MDIO_CFG[BSY] being cleared, when performing an
- MDIO read operation.
-
-- fsl,erratum-a011043
- Usage: optional
- Value type: <boolean>
- Definition: Indicates the presence of the A011043 erratum
- describing that the MDIO_CFG[MDIO_RD_ER] bit may be falsely
- set when reading internal PCS registers. MDIO reads to
- internal PCS registers may result in having the
- MDIO_CFG[MDIO_RD_ER] bit set, even when there is no error and
- read data (MDIO_DATA[MDIO_DATA]) is correct.
- Software may get false read error when reading internal
- PCS registers through MDIO. As a workaround, all internal
- MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.
-
-For internal PHY device on internal mdio bus, a PHY node should be created.
-See the definition of the PHY node in booting-without-of.txt for an
-example of how to define a PHY (Internal PHY has no interrupt line).
-- For "fsl,fman-mdio" compatible internal mdio bus, the PHY is TBI PHY.
-- For "fsl,fman-memac-mdio" compatible internal mdio bus, the PHY is PCS PHY.
- The PCS PHY address should correspond to the value of the appropriate
- MDEV_PORT.
