Subject: [PATCHv3 03/35] ARM: OMAP2+: PRM: add generic API for clear_mod_irqs
Date: Wed, 25 Feb 2015 21:04:13 +0200	[thread overview]
Message-ID: <1424891085-10392-4-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1424891085-10392-1-git-send-email-t-kristo@ti.com>

OMAP2/3 now use generic API for the prm_clear_mod_irqs, the SoC specific
implementation details are provided through prm_ll_data.
