* bootcounter: add DM support for memory based bootcounterHeiko Schocher2020-03-161-0/+21
| | | | | | | | | | | add DM/DTS support for the memory based bootcounter in drivers/bootcount/bootcount.c. Let the old implementation in, so boards which have not yet convert to DM/DTS do not break. Signed-off-by: Heiko Schocher <hs@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>
* dm: i2c-gpio: add support for clock stretchingHeiko Schocher2020-03-161-0/+2
| | | | | | | | | | | | | | | | 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 is having DT which doesn't cover all options currently supported by driver. DT binding is aligned with Linux kernel version available here. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ti,dp83867.txt Based on my talk with Grygorii Strashko better will be to remove it. Also Linux kernel bindings are being converted to yaml that's another reason to do it only at one place.

| * doc: net: Rewrite network driver documentationAndre Przywara2020-03-093-215/+322
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | doc/README.drivers.eth seems like a good source for understanding U-Boot's network subsystem, but is only talking about legacy network drivers. This is particularly sad as proper documentation would help in porting drivers over to the driver model. Rewrite the document to describe network drivers in the new driver model world. Most driver callbacks/methods are almost identical in their semantic, but recv() differs in some important details. Also keep some parts of the original text at the end, to help understanding old drivers. Add some hints on how to port drivers over. This also uses the opportunity to reformat the document in reST, on the way moving it into doc/driver-model and adding it into the structure there.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the `dfu` command is called from the U-Boot environment, it now accepts an optional parameter that specifies a timeout (in seconds). If a DFU connection is not made within that time the `dfu` command exits (as it would if Ctrl+C was pressed). If the timeout is left empty or being zero the `dfu` command behaves as it does now. This is useful for allowing U-Boot to check to see if anything wants to upload new firmware before continuing to boot. The patch is based on the commit https://github.com/01org/edison-u-boot/commit/5e966ccc3c65c18c9783741fa04e0c45e021780c by Sebastien Colleur, which has been heavily reworked due to U-Boot changes in the past.
