|\ | | | | | | - DFU updates
| * dfu: Add optional timeout parameterAndy Shevchenko2020-01-071-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * dm: pci: Allow delaying auto-config until after relocationSimon Glass2019-12-151-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| * dm: spi: Change cs_info op to return -EINVAL for invalid cs numBin Meng2019-10-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need distinguish the following two situations in various SPI APIs: - given chip select num is invalid - given chip select num is valid, but no device is attached Currently -ENODEV is returned for both cases. For the first case, it's more reasonable to return -EINVAL instead of -ENODEV for invalid chip select numbers.
