| | | | | | | | | | | | | | We now have usb_register_otg_device() to register an "otg" device. Use it and drop the custom code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | When the role in the device tree is specified as "otg" then register a otg device in barebox so that the user can configure the desired mode. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * usb: Add function to register otg devSascha Hauer2019-11-213-1/+74
| | | | | | | | | | | | | | | | We have two drivers in the tree which register an "otg" device to configure the host/peripheral switching. Before introducing a third driver create a common function for it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * usb: dwc3: remove unnecessary warningSascha Hauer2019-11-211-6/+3
| | | | | | | | | | | | | | | | | | The dwc3 driver warns when the value written to DWC3_GFLADJ happens to be same as already read from the register. This always happens when the driver was previously running when started 2nd stage from another barebox. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | remoteproc: add support for starting st,stm32mp1-m4Ahmad Fatoum2019-11-253-0/+210
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The STM32MP157C-DK2 has a Cortex-M4 MCU in addition to the two Cortex-A7 MPUs. This remoteproc driver allows barebox running on a Cortex-A7 core to bootstrap the MCU with an ELF binary. Code ported from Linux v5.3 with rpmsg bits removed.

| * | remoteproc: register a device for new remoteproc instancesAhmad Fatoum2019-11-251-6/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct rproc has a device_d dev field, but so far it was unregistered. The implementation had a few downsides: - dev_printf prints NULL, because the unique_name of the device is NULL - The name used by firmwareload is the device tree node's name, which might be unnecessarily verbose, e.g. mlahb:m4@10000000.of - All remoteproc devices are given the same (unused) name and index Fix these by registering a device for the remoteproc and using it where appropriate. While at it, allow the remoteproc name to come from a device tree alias as well. This breaks user behavior in that firmwareload now uses the alias or remoteprocN to reference the remoteproc instance. This is probably acceptable as the driver is a very recent addition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The stm32_iwdg watchdog can't be disabled. To have the wd commant report this fact correctly to the user, the ->set_timeout needs to return -ENOSYS which is interpreted as "Watchdog cannot be disabled" instead of -EINVAL which means "Timeout value out of range".

This just adds very basic PIO read/write support. This submission is also missing the tap delay configuration, which is required for the high speed modes on the ZynqMP, but this can be added in a separate patch once it is clear how the interface for this feature should look like. The driver skeleton was provided by Michael, most of the actual driver porting work was done by Thomas and some coding style fixes and write support bug fixes added by Lucas.
