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.
