Subject: [PATCH 1/3] bus: ti-sysc: Fix initializing module_pa for modules without sysc register
Date: Tue, 26 Jan 2021 09:28:33 +0200	[thread overview]
Message-ID: <20210126072835.26551-2-tony@atomide.com> (raw)
In-Reply-To: <20210126072835.26551-1-tony@atomide.com>

We have interconnect target modules with no known registers using only
clocks and resets, but we still want to detect them based on the module
IO range. So let's call sysc_parse_and_check_child_range() earlier so we
have module_pa properly initialized.

Fixes: 2928135c93f8 ("bus: ti-sysc: Support modules without control registers")
