2023-09-19drivers: misc: k3_avs: Add Linux compatibles to maintain syncReid Tonking
The ti,j7200-vtm and ti,j721e-vtm compatibles are used for voltage and thermal monitoring (VTM) by (drivers/thermal/k3_j72xx_bandgap.c) in Linux, but the same hardware is used for adaptive voltage scaling (AVS) in u-boot, This brings both drivers in line with the same compatibles. Since the j7200 uses the config as the j721e, the data is inherited from j721e vs creating a duplicate Signed-off-by: Neha Francis <n-francis@ti.com> Signed-off-by: Reid Tonking <reidt@ti.com> Reviewed-by: Nishanth Menon <nm@ti.com>
2023-09-15board: usb: Replace legacy usb_gadget_handle_interrupts()Marek Vasut
The usb_gadget_handle_interrupts() is no longer used anywhere, replace the remaining uses with dm_usb_gadget_handle_interrupts() which takes udevice as a parameter. Some of the UDC drivers currently ignore the index parameter altogether, those also ignore the udevice and have to be reworked. Other like the dwc3_uboot_handle_interrupt() had to be switched from index to udevice look up to avoid breakage.

2023-09-13phy: Set phy->dev to NULL when generic_phy_get_by_index_nodev() failsJonas Karlman
Generic phy helpers typically use generic_phy_valid() to determine if the helper should perform its function on a passed struct phy. generic_phy_valid() treat any struct phy having phy->dev set as valid. With generic_phy_get_by_index_nodev() setting phy->dev to a valid struct udevice early, there can be situations where the struct phy is returned as valid when initialization in fact failed and returned an error. Fix this by setting phy->dev back to NULL when any of the calls to of_xlate ops, device_get_supply_regulator or phy_alloc_counts fail. Also extend the dm_test_phy_base test with a test where of_xlate ops fail.

2023-09-04usb: check for companion controller in uclassFabrice Gasnier
EHCI is usually used with companion controller (like OHCI) as companion controller. This information on the companion is missing currently in companion drivers. So, if the usb-uclass isn't aware, it may scan busses in any order: OHCI first, then EHCI. This is seen on STM32MP1 where DT probing makes the probe order to occur by increasing address (OHCI address < EHCI address). When a low speed or full-speed device is plugged in, it's not detected as EHCI should first detect it, and give ownership (handover) to OHCI. Current situation on STM32MP1 (with a low speed device plugged-in) STM32MP> usb start starting USB...

2023-08-30serial-uclass: reset gd->cur_serial_dev to NULL if serial not foundMaksim Kiselev
Reset gd->cur_serial_dev pointer to avoid calling non-relocated code from relocated code if a serial driver is not found and CONFIG_REQUIRE_SERIAL_CONSOLE is disabled. Here is detailed explanation of what this patch is trying to fix. U-boot calls the serial_find_console_or_panic() function twice. The first console setup occurs before U-boot relocation in the serial_init(). This stage uses simple FDT parsing and assigns gd->cur_serial_dev to a "serial" device that lives in non-relocated code too. The second console setup after U-boot relocation(from serial_initialize()) may use full live DT (if OF_LIVE enabled) probe sequence with buses, clocks, resets, etc... And if the console setup fails at this step, than we should be caught by panic_str("No serial driver found"). But... If we disable CONFIG_REQUIRE_SERIAL_CONSOLE, than we return from serial_init() with gd->cur_serial_dev pointing to the "old"(non-relocated) serial device. And if this area, where "old" serial device is placed, is changed (e.g. Linux kernel may be relocated at this address), than we will get an unexpected crash on the next call of printf().

2023-08-30pci: pcie-brcmstb: do not rely on CLKREQ# signalSam Edwards
When the Broadcom STB PCIe controller is initialized, it must be set into one of three CLKREQ# modes: "none"/"aspm"/"l1ss". The Linux driver, through today, hard-codes "aspm" since the vast majority of boards using this driver have a fixed PCIe bus with the CLKREQ# signal wired up. The Raspberry Pi CM4, however, can be connected to a plethora of PCIe devices, some of which do not connect the CLKREQ# line (they just leave it floating). So "aspm" mode is no longer appropriate in all cases. In Linux, there is a proposed patchset [1] to determine the proper mode. This doesn't really make sense in U-Boot's case, so we just change the assumption from "aspm" to "none" (which is always safe). This patch DOES resolve a real-world crash that occurs when U-Boot is running on a Raspberry Pi CM4 installed in slot 3 of a Turing Pi 2 cluster board.

2023-08-30pci: pcie-brcmstb: bring over some robustness improvements from LinuxSam Edwards
Since the initial U-Boot driver was ported here from Linux, the latter has had a few changes for robustness/stability. This patch brings over two of them: - Do not attempt to access the configuration space of a PCIe device if the link has gone down, as that will result in an asynchronous SError interrupt which will crash U-Boot. - Wait for the recommended 100ms after PERST# is deasserted. I sent this patch while debugging a crash involving PCIe, but these are unrelated improvements. I do not believe that this patch fixes any real-world bug.
