* common: Drop linux/printk.h from common headerSimon Glass2023-09-241-0/+1
| | | | | | | | | This old patch was marked as deferred. Bring it back to life, to continue towards the removal of common.h Move this out of the common header and include it only where needed. Signed-off-by: Simon Glass <sjg@chromium.org>
* drivers: fix debug string with fdt_addr_t inputJohan Jonker2023-05-061-2/+2
| | | | | | | | | The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU can expect 64-bit data from the device tree parser, so fix some debug strings with fdt_addr_t to be able to handle both sizes.

* phy: usbphyc: use regulator_set_enable_if_allowed for disabling vbus supplyPatrick Delaunay2022-12-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use regulator_set_enable_if_allowed() api instead of regulator_set_enable() while disabling vbus supply. This way the driver doesn't see an error when it disable an always-on regulator for VBUS. This patch is needed for STM32MP157C-DK2 board when the regulator v3v3: buck4 used as the phy vbus supply in kernel device tree is always on with the next hack for low power use-case: &usbphyc_port0 { ... /* * Hack to keep hub active until all connected devices are suspended * otherwise the hub will be powered off as soon as the v3v3 is disabled * and it can disturb connected devices. */ connector { compatible = "usb-a-connector"; vbus-supply = <&v3v3>; }; }; Without this patch and the previous update in DT the command "usb stop" failed and the next command "usb start" cause a crash.

* dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass2020-12-131-1/+1
| | | | | | | | | | | | This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: core: Create a new header file for 'compat' featuresSimon Glass2020-02-051-0/+1
| | | | | | | | | | | | At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.
