The AST2700 reuses the AST2600 watchdog block unchanged. Bind the driver to the aspeed,ast2700-wdt compatible and enable WDT_AST2600 on the AST2700.
Signed-off-by: Ryan Chen <[email protected]> --- The AST2700 reuses the AST2600 watchdog block with an identical register layout and reset behaviour, so no new driver is needed. Bind the existing ast2600 watchdog driver to the aspeed,ast2700-wdt compatible and allow WDT_AST2600 to be selected on the AST2700. --- drivers/watchdog/Kconfig | 6 +++--- drivers/watchdog/ast2600_wdt.c | 1 + 2 files changed, 4 insertions(+), 3 deletions(-) diff --git a/drivers/watchdog/Kconfig b/drivers/watchdog/Kconfig index b91727e1265..3c56c541505 100644 --- a/drivers/watchdog/Kconfig +++ b/drivers/watchdog/Kconfig @@ -130,11 +130,11 @@ config WDT_ASPEED Second Boot. config WDT_AST2600 - bool "Aspeed AST2600 watchdog timer support" - depends on WDT && ASPEED_AST2600 + bool "Aspeed AST2600/AST2700 watchdog timer support" + depends on WDT && (ASPEED_AST2600 || ASPEED_AST2700) default y help - Select this to enable watchdog timer for Aspeed ast2500/ast2400 devices. + Select this to enable watchdog timer for Aspeed ast2600/ast2700 devices.
