2022-10-26dt/bindings: memory: Add bindings for TI GPMC driverRoger Quadros2-0/+442
GPMC stands for General Purpose Memory Controller and it is present on many Texas Instruments SoCs. It supports a number of Asynchronous and Synchronous interfaces and has various settings to configure the bus interface. The DT bindings define all the various GPMC settings. As the GPMC supports multiple devices on the bus, each device is represented as a child and the respective GPMC settings are situated there. (see ti,gpmc-child.yaml) These binding docs are picked up from the Linux kernel. Signed-off-by: Roger Quadros <rogerq@kernel.org>
2022-10-24watchdog: introduce a u-boot,autostart propertyRasmus Villemoes1-4/+5
This is a companion to u-boot,noautostart. If one has a single watchdog device that one does want to have auto-started, but several others that one doesn't, the only way currently is to set the CONFIG_WATCHDOG_AUTOSTART and then use the opt-out for the majority. The main motivation for this is to add an autostarted watchdog device to the sandbox (to test a fix) without having to set AUTOSTART in sandbox_defconfig and add the noautostart property to the existing devices. But it's also nice for symmetry, and the logic in init_watchdog_dev() becomes simpler to read because we avoid all the negations. Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

Since both pm8916.c and pm8916_gpio.c are already supporting multiple Qcom SoCs, it makes sense to rename these drivers to pmic_qcom.c and qcom_pmic_gpio.c respectively.

2022-07-21watchdog: add pulse support to gpio watchdog driverPaul Doelle1-1/+7
A common external watchdog circuit is kept alive by triggering a short pulse on the reset pin. This patch adds support for this use case, while making the algorithm configurable in the devicetree. The "linux,wdt-gpio" driver being modified is based off the equivalent driver in the Linux kernel, which provides support for this algorithm. This patch brings parity to this driver, and is kept aligned with the functionality and devicetree configuration in the kernel. It should be noted that this adds a required property named 'hw_algo' to the devicetree binding, following suit with the kernel. I'm happy to make this backward-compatible if preferred.

2021-11-30stm32mp1: ram: remove the support of calibration resultPatrick Delaunay1-32/+0
The support of a predefined DDR PHY tuning result is removed for STM32MP1 driver because it is not needed at the supported frequency when built-in calibration is executed. The calibration parameters were provided in the device tree by the optional node "st,phy-cal", activated in ddr helper file by the compilation flag DDR_PHY_CAL_SKIP and filled with values generated by the CubeMX DDR utilities. This patch - updates the binding file to remove "st,phy-cal" support - updates the device trees and remove the associated defines - simplifies the STM32MP1 DDR driver and remove the support of the optional parameter "st,phy-cal" After this patch, the built-in calibration is always executed and the calibration registers are moved in the phy dynamic part; that allows manual tests.

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/1576768881-24971-2-git-send-email-madalin.bucur@oss.nxp.com/) 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".

2021-08-31watchdog: add gpio watchdog driverRasmus Villemoes1-0/+19
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.

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.
