* phy: freescale: imx8mq-usb: make i.MX8MP support more explicitAhmad Fatoum2024-02-201-2/+6
| | | | | | | | | | | | | | The driver was originally written for use with the i.MX8MQ's DWC3, but has been extended to also cover the i.MX8MP's DWC3. While we won't change the config symbol name, because that could break existing users, we can and should change the symbol prompt and help text as well as the dependency to reflect that the driver also targets the i.MX8MP.

* treewide: use dev_err_probe instead of comparisons against EPROBE_DEFERAhmad Fatoum2024-02-203-20/+6
| | | | | | | | | | | | | | Drivers should not need to compare an error value against EPROBE_DEFER. We have a number of drivers doing that though to decide whether to print an error or not. This error message will be lost if the probe is deferred, so use dev_err_probe to store the error in that case. While at it, we shorten the error messages a bit. dev_err_probe will already print the string 'error' before the error code string.

* phy: stm32-usbphyc: fix unbalanced phy exitAhmad Fatoum2023-11-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | On the STM32MP1, shutting down barebox can result in a ERROR: phy1: phy exit failed --> -22 message printed to the console. This is because the regulator is disabled more often than it was enabled, because stm32_usbphyc_pll_disable is called twice: - Once from stm32_usbphyc_remove calling stm32_usbphyc_phy_exit - Once from dwc2_remove calling phy_exit -> stm32_usbphyc_phy_exit The code is taken from Linux and likely causes no issues there, because devices are removed in reverse probe order, which barebox doesn't enforce. Properly solving this would be a larger endeavour, so for now just fix the stm32-usbphyc driver to ignore reference count dropping below zero and only call __stm32_usbphyc_pll_disable once.

* phy: stm32: usb: depend on COMMON_CLKAhmad Fatoum2023-06-131-0/+1
| | | | | | | | | | | The stm32-usbphyc driver registers a clock with the common clock framework, so compile testing without COMMON_CLK understandably fails and can't be expected to work.

* treewide: add MODULE_DEVICE_TABLE markersAhmad Fatoum2023-06-134-0/+4
| | | | | | | | | | | | | | | | Syncing device trees with Linux upstream can lead to breakage, when the device trees are switched to newer bindings, which are not yet supported in barebox. To make it easier to spot such issues, we want to start applying some heuristics to flag possibly problematic DT changes. One step towards being able to do that is to know what nodes barebox actually consumes. Most of the nodes have a compatible entry, which is matched by an array of of_device_id, so let's have MODULE_DEVICE_TABLE point at it for future extraction.
