2021-09-01ata: ahci-pci: Add new option CONFIG_SPL_AHCI_PCIPali Rohár
This new option allows to disable ahci-pci driver in SPL. Disabling it is needed when SPL_PCI is not enabled as ahci-pci depends on PCI. This change fixes following compile error when CONFIG_SPL_SATA_SUPPORT is enabled and SPL_PCI is disabled.

2021-09-01rtc: ds1307: Fix incorrect clock reset for DS13xxCallum Sinclair
The ds1307 driver also supports the DS1339 and DS1340. However, in ds1307_rtc_reset the register writes assume that the chip is a DS1307. This is evident in the writing of bits SQWE, RS1, RS0 to the control register. While this applies correctly to the DS1307, on a DS1340 the control register doesn't contain those bits (instead, the register is used for clock calibration). By writing these bits the clock calibration will be changed and the chip can become non-functional after a reset call. Signed-off-by: Callum Sinclair <callum.sinclair@alliedtelesis.co.nz>

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.

2021-08-31watchdog: wdt-uclass.c: handle all DM watchdogs in watchdog_reset()Rasmus Villemoes
A board can have and make use of more than one watchdog device, say one built into the SOC and an external gpio-petted one. Having wdt-uclass only handle the first is both a little arbitrary and unexpected. So change initr_watchdog() so we visit (probe) all DM watchdog devices, and call the init_watchdog_dev helper for each. Similarly let watchdog_reset() loop over the whole uclass - each having their own ratelimiting metadata, and a separate "is this device running" flag. This gets rid of the watchdog_dev member of struct global_data. We do, however, still need the GD_FLG_WDT_READY set in initr_watchdog(). This is because watchdog_reset() can get called before DM is ready, and I don't think we can call uclass_get() that early. The current code just returns 0 if "getting" the first device fails - that can of course happen because there are no devices, but it could also happen if its ->probe call failed. In keeping with that, continue with the handling of the remaining devices even if one fails to probe. This is also why we cannot use uclass_probe_all(). If desired, it's possible to later add a per-device "u-boot,autostart" boolean property, so that one can do CONFIG_WATCHDOG_AUTOSTART per-device.

2021-08-31watchdog: wdt-uclass.c: add wdt_stop_all() helperRasmus Villemoes
Since the watchdog_dev member of struct global_data is going away in favor of the wdt-uclass handling all watchdog devices, prepare for that by adding a helper to call wdt_stop() on all known devices. If an error is encountered, still do wdt_stop() on remaining devices, but remember and return the first error seen. Initially, this will only be used in one single place (board/alliedtelesis/x530/x530.c). Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

As a step towards handling all DM watchdogs in watchdog_reset(), use a per-device flag to keep track of whether the device has been started instead of a bit in gd->flags. We will still need that bit to know whether we are past initr_watchdog() and hence have populated gd->watchdog_dev - incidentally, that is how it was used prior to commit 9c44ff1c5f3c.

As per SD spec when SD host controller is reset, it takes 1000msec to detect the card state. In case, if we enable the sd bus voltage & card detect state is not stable, then host controller will disable the sd bus voltage. In case of warm/subsystem reboot, due to unstable card detect state host controller is disabling the sd bus voltage to sd card causing sd card timeout error. So we wait for a maximum of 1000msec to get the card detect state stable before we enable the sd bus voltage. This current fix is workaround for now, this needs to be analysed further.
