2020-03-16dm: i2c-gpio: add support for clock stretchingHeiko Schocher
This adds support for clock stretching to the i2c-gpio driver. This is accomplished by switching the GPIO used for the SCL line to an input when it should be driven high, and polling on the SCL line value until it goes high (indicating that the I2C slave is no longer pulling it low). This is enabled by default; for gpios which cannot be configured as inputs, the i2c-gpio,scl-output-only property can be used to fall back to the previous behavior.

2020-03-03misc: pmic_esm: Add support for PMIC ESM driverTero Kristo
The ESM (Error Signal Monitor) is used on certain PMIC versions to handle error signals propagating from rest of the system. If these reach the PMIC, it is typically a last resort fatal error which requires a system reset. The ESM driver does the proper configuration for the ESM module to reach this end goal. Initially, only TPS65941 PMIC is supported for this. Signed-off-by: Tero Kristo <[email protected]>
2020-03-03misc: k3_esm: Add support for Texas Instruments K3 ESM driverTero Kristo
The ESM (Error Signaling Module) is used to route error signals within the K3 SoCs somewhat similar to interrupts. The handling for these is different though, and can be routed for hardware error handling, to be handled by safety processor or just as error interrupts handled by the main processor. The u-boot level ESM driver is just used to configure the ESM signals so that they get routed to proper destination. Signed-off-by: Tero Kristo <[email protected]>

2020-02-07dm: irq: Add support for requesting interruptsSimon Glass
At present driver model supports the IRQ uclass but there is no way to request a particular interrupt for a driver. Add a mechanism, similar to clock and reset, to read the interrupts required by a device from the device tree and to request those interrupts. U-Boot itself does not have interrupt-driven handlers, so just provide a means to read and clear an interrupt. This can be useful to handle peripherals which must use an interrupt to determine when data is available, for example. Bring over the basic binding file as well, from Linux v5.4. Note that the older binding is not supported in U-Boot; the newer 'special form' must be used. Add a simple test of the new functionality.

2019-12-15dm: pci: Allow delaying auto-config until after relocationSimon Glass
At present PCI auto-configuration happens in U-Boot both before and after relocation. This is a waste of time and may mess up static addresses used in board_init_f(). Adjust the code to supporting doing auto-configuration once, after relocation, under control of a device-tree property. This is needed for Apollo Lake for debugging the silicon-init code. Once the UART is moved to a different MMIO address the debug UART does not work and any debug output in Apollo Lake's arch_fsp_init_r() causes a hang.

2019-12-09dt-bindings: phy: dp83867: Add documentation for disabling clock outputGrygorii Strashko
Based on commit 980066e6d964 ("dt-bindings: phy: dp83867: Add documentation for disabling clock output") of mainline linux kernel. The clock output is generally only used for testing and development and not used to daisy-chain PHYs. It's just a source of RF noise afterward. Add a mux value for "off". I've added it as another enumeration to the output property. In the actual PHY, the mux and the output enable are independently controllable. However, it doesn't seem useful to be able to describe the mux setting when the output is disabled. Document that PHY's default setting will be left as is if the property is omitted.

2019-09-04drivers: net: add marvell MDIO driverAlex Marginean
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.

2019-07-25net: tsec: Change compatible strings to match LinuxVladimir Oltean
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.
