This is documented for example in am437x TRM for DMTIMER_TIOCP_CFG register. The am335x TRM just says that SOFTRESET bit value 1 means reset is ongoing, but it behaves the same way clearing after reset is done. With the ti-sysc driver handling this automatically based on no sysstatus register defined, we see warnings if SYSC_HAS_RESET_STATUS is missing in the legacy platform data: ti-sysc 48042000.target-module: sysc_flags 00000222 != 00000022 ti-sysc 48044000.target-module: sysc_flags 00000222 != 00000022 ti-sysc 48046000.target-module: sysc_flags 00000222 != 00000022 ... Let's fix these warnings by adding SYSC_HAS_RESET_STATUS. Let's also remove the useless parentheses while at it. If it turns out we do have ti,sysc-omap4 compatible devices without a working SOFTRESET bit we can set up additional quirk handling for it.
