This adds the PCLK clock to the Aspeed watchdog blocks. I am not directly familiar with the Aspeed clocking, but since the IP is derived from Faraday FTWDT010 it probably has the ability to run the watchdog on the PCLK if desiredThis is true for the AST2400, but not the AST2500 where the only option is EXTCLK (1MHz).The IP block/cell certainly has a PCLK even if it cannot be used to drive the watchdog timer. It is necessary to interface the SoC interconnect.
Hah, yep, brain-fade. Cheers, Andrew

+???????????????????????????clocks = <&clk_apb>;+?????????????????????????????clock-names = "PCLK";Given the comment above, shouldn't we be doing something like the following instead for each of the watchdogs? +???????????????????????????????faraday,use-extclk; +???????????????????????????????clock-names = "EXTCLK";So that will be added too, later, when there is a 1MHz clock to reference in the device tree. I guess after Joel's patches. Yours, Linus Walleij
