2020-03-31gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signalKlaus H. Sorensen
Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi chip select, SPISEL_BOOT, that is used by the boot code to boot from flash. This chip select will typically be used to select a SPI boot flash. The SPISEL_BOOT signal is controlled by a single bit in the SPI_CS register. Implement a gpio driver for the spi chip select register. This allows a spi driver capable of using gpios as chip select, to bind a chip select to SPISEL_BOOT. It may be a little odd to do this as a GPIO driver, since the signal is neither GP or I, but it is quite convenient to present it to the spi driver that way. The alternative it to teach mpc8xxx_spi to handle the SPISEL_BOOT signal itself (that is how it's done in the linux kernel, see commit 69b921acae8a) Signed-off-by: Klaus H.

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.

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.

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.

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.
