2019-08-12watchdog: omap_wdt: Disable DM watchdog support in SPLSuniel Mahesh1-0/+7
This patch disables DM watchdog support for SPL builds and uses the legacy omap watchdog driver on TI AM335x chipsets. The following build error is reported if DM watchdog support was enabled in SPL: CC spl/drivers/usb/gadget/rndis.o LD spl/drivers/usb/gadget/built-in.o LD spl/drivers/usb/musb-new/built-in.o LD spl/drivers/built-in.o LD spl/u-boot-spl arm-linux-ld.bfd: u-boot-spl section .u_boot_list will not fit in region .sram arm-linux-ld.bfd: region .sram overflowed by 440 bytes make[1]: *** [spl/u-boot-spl] Error 1 make: *** [spl/u-boot-spl] Error 2 Adjusted WATCHDOG_RESET macro accordingly. Earlier it was pointing to hw_watchdog_reset. Since CONFIG_WATCHDOG replaces CONFIG_HW_WATCHDOG, now WATCHDOG_RESET macro points to watchdog_reset. This watchdog_reset is not defined anywhere for am33xx/omap2 and needs to be defined. Fixed this by simply calling hw_watchdog_reset in watchdog_reset. Built and tested on AM335x device (BeagleboneBlack), compile tested for all other AM33xx/omap2 based boards.

2019-08-12watchdog: omap_wdt: Convert watchdog driver to use DT and DMSuniel Mahesh3-1/+123
This patch adds device tree and driver model watchdog support, converts the legacy omap watchdog driver to driver model for TI AM335x chipsets. The following compile warning is removed: ===================== WARNING ====================== This board does not use CONFIG_WDT (DM watchdog support). Please update the board to use CONFIG_WDT before the v2019.10 release. Failure to update by the deadline may result in board removal. See doc/driver-model/MIGRATION.txt for more info. ==================================================== CONFIG_HW_WATCHDOG is no more a default option for AM33XX devices after DT/DM conversion, adjusted kconfig accordingly. DM watchdog support is enabled by default in SPL. The SPL image doesn't fit into SRAM because of size constraints and build breaks with an overflow. For this reason DM watchdog support should be disabled in SPL, driver code should be adjusted accordingly to serve this purpose. Built and tested on AM335x device (BeagleboneBlack), compile tested for all other AM33xx based boards. Signed-off-by: Suniel Mahesh <sunil.m@techveda.org>

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.

2019-04-26watchdog: Implement generic watchdog_reset() versionStefan Roese2-0/+27
This patch tries to implement a generic watchdog_reset() function that can be used by all boards that want to service the watchdog device in U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG. Without this approach, new boards or platforms needed to implement a board specific version of this functionality, mostly copy'ing the same code over and over again into their board or platforms code base. With this new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). This patch also adds a new flag to the GD flags, to flag that the watchdog is ready to use and adds the pointer to the watchdog device to the GD. This enables us to remove the global "watchdog_dev" variable, which was prone to cause problems because of its potentially very early use in watchdog_reset(), even before the BSS is cleared.

2019-01-21watchdog: armada_37xx: Fix compliance with kernel's driverMarek Behún1-42/+67
The Armada 37xx watchdog driver was recently accepted for mainline kernel by watchdog subsystem maintainer, but the driver works a little different than the one in U-Boot. This patch fixes this. In the previous implementation there was a tiny period of time when the watchdog was disabled and the system was vulnerables - this was during pinging, which was done by disabling, setting, and enabling the counter. Now pinging is done without disabling the watchdog. We use 2 counters: Counter 1 is the watchdog counter - on expiry, the system is reset. Counter 0 is used to reset Counter 1 to start counting from the set timeout again. So Counter 1 is set to be reset on Counter 0 expiry event event and pinging is done by forcing an immediate expiry event on Counter 0.

2018-11-14watchdog: Remove DM_FLAG_PRE_RELOC flag in various driversBin Meng1-1/+0
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before relocation. However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
