Subject: [PATCH 11/13] bus: ti-sysc: Detect uarts also on omap34xx
Date: Mon, 27 May 2019 23:24:12 -0700	[thread overview]
Message-ID: <20190528062414.27192-12-tony@atomide.com> (raw)
In-Reply-To: <20190528062414.27192-1-tony@atomide.com>

Looks like we currently only detect UART on omap36xx, let's also
add support for omap34xx. And let's also fix the SWSUP mode, it should
be SWSUP_SIDLE for omap3, not SWSUP_SIDLE_ACT like for omap4 and later.

Note that we are still booting omap3 for most part without ti-sysc,
so no need to treat this change as a fix.
