2019-09-04drivers: net: add marvell MDIO driverAlex Marginean1-0/+15
This patch adds a separate driver for the MDIO interface of the Marvell Ethernet controllers based on driver model. There are two reasons to have a separate driver rather than including it inside the MAC driver itself: *) The MDIO interface is shared by all Ethernet ports, so a driver must guarantee non-concurrent accesses to this MDIO interface. The most logical way is to have a separate driver that handles this single MDIO interface, used by all Ethernet ports. *) The MDIO interface is the same between the existing mv643xx_eth driver and the new mvneta/mvpp2 driver. Even though it is for now only used by the mvneta/mvpp2 driver, it will in the future be used by the mv643xx_eth driver as well. This driver supports SMI IEEE for 802.3 Clause 22 and XSMI for IEEE 802.3 Clause 45. This patch also adds device tree binding for marvell MDIO driver.

2019-09-04doc: bindings: add mdio.txt describing generic MDIO propertiesAlex Marginean1-0/+36
Adds a binding document for mdio. A notable deviation from corresponding Linux binding is the introduction of device-name optional property, which can be used to name MDIO buses. Two reset optional properties described by Linux binding are also not present as they don't seem to be used in U-Boot at this time.

2019-07-25net: tsec: Change compatible strings to match LinuxVladimir Oltean1-2/+2
In the case of the tsec network driver, so far there has been no mainline user of DM_ETH where the DT bindings get used. In the case of the mdio bus, it looks like the "fsl,tsec-mdio" string was made up for the documentation, but there is no mainline code that parses the "compatible" property anyway. In both cases, there are no DT blobs that contain the old strings. So change the documentation to "fsl,etsec2" for the Ethernet ports and "fsl,etsec2-mdio" for the MDIO buses, which are strings that Linux also uses, at least for LS1021A. More compatible strings can be added once other (PowerPC) SoCs are migrated to DM_ETH. The current ls1021a.dtsi doesn't match what was documented for the MDIO buses anyway (the "compatible" is "gianfar" currently). This will be fixed in the next patch.

2019-05-09net: phy: micrel: Use correct skew values on KSZ9021James Byrne1-0/+27
Commit ff7bd212cb8a ("net: phy: micrel: fix divisor value for KSZ9031 phy skew") fixed the skew value divisor for the KSZ9031, but left the code using the same divisor for the KSZ9021, which is incorrect. The preceding commit c16e69f702b1 ("net: phy: micrel: add documentation for Micrel KSZ90x1 binding") added the DTS documentation for the KSZ90x1, changing it from the equivalent file in the Linux kernel to correctly state that for this part the skew value is set in 120ps steps, whereas the Linux documentation and driver continue to this day to use the incorrect value of 200 that came from the original KSZ9021 datasheet before it was corrected in revision 1.2 (Feb 2014). This commit sorts out the resulting confusion in a consistent way by making the following changes: - Update the documentation to be clear about what the skew values mean, in the same was as for the KSZ9031. - Update the Micrel PHY driver to select the appropriate divisor for both parts. - Adjust all the device trees that state skew values for KSZ9021 PHYs to use values based on 120ps steps instead of 200ps steps. This will result in the same values being programmed into the skew registers as the equivalent device trees in the Linux kernel do, where it incorrectly uses 200ps steps (since that's where all these device trees were copied from).

2019-04-11DM: I2C: Introduce 'u-boot, i2c-transaction-bytes' propertyLukasz Majewski1-0/+5
The 'u-boot,i2c-transaction-bytes' device tree property provides information regarding number of bytes transferred by a device in a single transaction. This change is necessary to avoid hanging devices after soft reset. One notable example is communication with MC34708 device: 1. Reset when communicating with MC34708 via I2C. 2. The u-boot (after reboot -f) tries to setup the I2C and then calls force_idle_bus. In the same time MC34708 still has some data to be sent (as it transfers data in 24 bits chunks). 3. The force_idle_bus() is not able to make the bus idle as 8 SCL clocks may be not enough to have the full transmission. 4. We end up with I2C inconsistency with MC34708. This PMIC device requires 24+ SCL cycles to make finish any pending I2C transmission. Signed-off-by: Lukasz Majewski <lukma@denx.de>

Only setting/reading the programmed voltage is supported at this time and the following device functionality remains unsupported: - switching the selected voltage (via a GPIO) - disabling the voltage output via software-control This matches the functionality of the Linux driver.

On a modern system that exposes multiple devices in a DTS-configurable way, this is less than optimal and a interface to DM-based devices will be desirable. This adds a simple driver that is DM-aware and configurable via DTS.
