2021-10-31iommu: Add IOMMU uclassMark Kettenis
This uclass is intended to manage IOMMUs on systems where the IOMMUs are not in bypass mode by default. In that case U-Boot cannot ignore the IOMMUs if it wants to use devices that need to do DMA and sit behind such an IOMMU. This initial IOMMU uclass implementation does not implement and device ops and is intended for IOMMUs that have a bypass mode that does not require address translation. Support for IOMMUs that do require address translation is planned and device ops will be defined when support for such IOMMUs will be added.

2021-09-28net: replace the "xfi" phy-mode with "10gbase-r"Vladimir Oltean
As part of the effort of making U-Boot work with the same device tree as Linux, there is an issue with the "xfi" phy-mode. To be precise, in Linux there was a discussion (for those who have time to read: https://lore.kernel.org/netdev/[email protected]/) which led to a patch: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=c114574ebfdf42f826776f717c8056a00fa94881 TL;DR: "xfi" was standardized in Linux as "10gbase-r". This patch changes the relevant occurrences in U-Boot to use "10gbase-r" instead of "xfi" wherever applicable.

2021-08-31watchdog: add gpio watchdog driverRasmus Villemoes
A rather common kind of external watchdog circuit is one that is kept alive by toggling a gpio. Add a driver for handling such a watchdog. The corresponding linux driver apparently has support for some watchdog circuits which can be disabled by tri-stating the gpio, but I have never actually encountered such a chip in the wild; the whole point of adding an external watchdog is usually that it is not in any way under software control. For forward-compatibility, and to make DT describe the hardware, the current driver only supports devices that have the always-running property. I went a little back and forth on whether I should fail ->probe or only ->start, and ended up deciding ->start was the right place. The compatible string is probably a little odd as it has nothing to do with linux per se - however, I chose that to make .dts snippets reusable between device trees used with U-Boot and linux, and this is the (only) compatible string that linux' corresponding driver and DT binding accepts. I have asked whether one should/could add "wdt-gpio" to that binding, but the answer was no: https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/ If someone feels strongly about this, I can certainly remove the "linux," part from the string - it probably wouldn't the only place where one can't reuse a DT snippet as-is between linux and U-Boot.

2021-07-31arm64: a37xx: pinctrl: Correct PWM pins definitionsMarek Behún
The PWM pins on North Bridge on Armada 37xx can be configured into PWM or GPIO functions. When in PWM function, each pin can also be configured to drive low on 0 and tri-state on 1 (LED mode). The current definitions handle this by declaring two pin groups for each pin: - group "pwmN" with functions "pwm" and "gpio" - group "ledN_od" ("od" for open drain) with functions "led" and "gpio" This is semantically incorrect. The correct definition for each pin should be one group with three functions: "pwm", "led" and "gpio". Change the "pwmN" groups to support "led" function. Remove "ledN_od" groups. This cannot break backwards compatibility with older device trees: no device tree uses it since there is no PWM driver for this SOC yet. Also "ledN_od" groups are not even documented.

Having the modes associated with the magic value generated based on the GPIO values, allows the reboot mode uclass to select the proper mode.

2021-04-10pwm: Add a driver for Chrome OS EC PWMAlper Nebi Yasak
This PWM is used in rk3399-gru-bob and rk3399-gru-kevin to control the display brightness. We can only change the duty cycle, so on set_config() we just try to match the duty cycle that dividing duty_ns by period_ns gives us. To disable, we set the duty cycle to zero while keeping the old value for when we want to re-enable it. The cros_ec_set_pwm_duty() function is taken from Depthcharge's cros_ec_set_bl_pwm_duty() but modified to use the generic pwm type. The driver itself is very loosely based on rk_pwm.c for the general pwm driver structure. The devicetree binding file is from Linux, before it was converted to YAML at 5df5a577a6b4 ("dt-bindings: pwm: Convert google,cros-ec-pwm.txt to YAML format") in their repo.

This uclass is intended to provide a way to obtain information about a U-Boot board. But the concept of a U-Boot 'board' is the whole system, not just one circuit board, meaning that 'board' is something of a misnomer for this uclass. In addition, the name 'board' is a bit overused in U-Boot and we want to use the same uclass to provide SMBIOS information. The obvious name is 'system' but that is so vague as to be meaningless. Use 'sysinfo' instead, since this uclass is aimed at providing information on the system. Rename everything accordingly.
