When you enable CONFIG_OF_LIVE, you will end up with a lot of conversions. To help this tedious work, this commit converts devfdt_get_addr_ptr() to dev_read_addr_ptr() by coccinelle. I also removed redundant casts because dev_read_addr_ptr() returns an opaque pointer.

2020-08-22dm: core: Fix devfdt_get_addr_ptr return valueOvidiu Panait
According to the description of devfdt_get_addr_ptr, this function should return NULL on failure, but currently it returns (void *)FDT_ADDR_T_NONE. Fix this by making devfdt_get_addr_ptr return NULL on failure, as described in the function comments. Also, update the drivers currently checking (void *)FDT_ADDR_T_NONE to check for NULL.

2020-08-11watchdog: Add support for K3 RTI watchdogJan Kiszka
This is based on the Linux kernel driver for the RTI watchdog. To actually reset the system on an AM65x, it requires firmware running on the R5 that accepts the NMI and issues the actual system reset via TISCI. Kind of an iTCO, except that this watchdog hardware has support for no-way-out, and only for that. On the J721E, reset works without extra firmware help when routing the RTI interrupt via the ESM.

2020-07-27Watchdog: introduce ARM SBSA watchdog driverZhao Qiang
According to Server Base System Architecture (SBSA) specification, the SBSA Generic Watchdog has two stage timeouts: the first signal (WS0) is for alerting the system by interrupt, the second one (WS1) is a real hardware reset. More details about the hardware specification of this device: ARM DEN0029B - Server Base System Architecture (SBSA) This driver can operate ARM SBSA Generic Watchdog as a single stage In the single stage mode, when the timeout is reached, your system will be reset by WS1. The first signal (WS0) is ignored.

2020-07-09drivers: rename drivers to match compatible stringWalter Lozano
When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.

The mpc8xx watchdog can work either in 'reset mode' or 'NMI mode'. The selection can be done at startup only. It is desirable to select the mode without rebuilding U-boot. It is also desirable to disable the watchdog without rebuilding. At watchdog startup, check environment variable 'watchdog_mode'. If it is 'off', the watchdog is not started. If it is 'nmi', the watchdog is started in NMI mode. Otherwise, it is started in reset mode which is the default mode.

2020-04-15watchdog: honour hw_margin_ms DT propertyRasmus Villemoes
Some watchdog devices, e.g. external gpio-triggered ones, must be reset more often than once per second, which means that the current rate-limiting logic in watchdog_reset() fails to keep the board alive. gpio-wdt.txt in the linux source tree defines a "hw_margin_ms" property used to specifiy the maximum time allowed between resetting the device. Allow any watchdog device to specify such a property, and then use a reset period of one quarter of that. We keep the current default of resetting once every 1000ms.

Commit f3729ba6e7b2 ("watchdog: mpc8xx_wdt: Watchdog driver and macros cleanup") switched the watchdog to CONFIG_WATCHDOG.

The watchdog timer value was never updated in the hardware by this driver, so the watchdog triggered on some random stale value that was left in the hardware. The TI SPRUH37C says, quote: 20.4.3.9 Modifying Timer Count/Load Values and Prescaler Setting ... After a write access, the load register value and prescaler ratio registers are updated immediately, but new values are considered only after the next consecutive counter overflow or after a new trigger command (the WDT_WTGR register). This means at least one trigger must happen. The driver probably depended on someone calling it's .reset() callback, however that is not guaranteed e.g. if the WDT operates without servicing.

2019-08-05watchdog: mtk_wdt: Cosmetic cleanup of latest changesStefan Roese
This patch cleans up some coding style related issues in the mtk_wtd driver to make this driver comply again with the U-Boot coding style standards. The only minimal functional change is that the timeout parameter is now passed in (u64) instead of (unsigned int) from mtk_wdt_start() to mtk_wdt_set_timeout(), preserving the original value.
