Benoit,
HSI has no RESET_STATUS bit in SYSCONFIG register.
Yes indeed, the RESETDONE is inside HSI_SYSSTATUS.
And this is what that flag is meaning: SYSS_HAS_RESET_STATUS, with the
SYSS prefix.
The other one will be SYSC_HAS_RESET_STATUS with the SYSC prefix.
I know this is confusing, like the HW spec :-)
The SYSC should be :
static struct omap_hwmod_class_sysconfig omap44xx_hsi_sysc = {
.rev_offs = 0x0000,
.sysc_offs = 0x0010,
.syss_offs = 0x0014,
.sysc_flags = (SYSC_HAS_AUTOIDLE | SYSC_HAS_EMUFREE |
SYSC_HAS_MIDLEMODE | SYSC_HAS_SIDLEMODE |
--- SYSC_HAS_SOFTRESET | SYSS_HAS_RESET_STATUS),
So these flags are fine.

Subject: [PATCH 2/6] OMAP4: hwmod data: Add MSTANDBY_SMART_WKUP flag
Add the flag to every IPs that support it to allow the
framework to enable it instead of the SMART_STANDBY default
mode.
Without that, an IP with busmaster capability will not
be able to wakeup the interconnect at all.
