Yes agreed.

Let's not change SYSC_OMAP4_SOFTRESET as only the ti-sysc
driver needs to know that and it can be set based on the
compatible.

How about replace ddata->cfg.quirks & SYSC_QUIRK_RESET_STATUS
test with just ddata->cfg.syss_mask test in your sysc_reset()?

We still need to set SYSC_QUIRK_RESET_STATUS too for pdata
callbacks.
