Silicon & boards are not yet ready. I checked internally about your request, I had been told that once boards are ready, it can be made available to the maintainers. >> Powerdomain & Clockdomain data has been added separately as it was not >> giving much advantage reusing AM335x ones (runtime updates required >> was getting too ugly).

PRCM is derived from AM335x, but modified such that it is more aligned with OMAP4 (especially w.r.t register offsets) Regards Afzal From mboxrd@z Thu Jan 1 00:00:00 1970 From: afzal@ti.com (Afzal Mohammed) Date: Wed, 28 Aug 2013 17:33:00 +0530 Subject: [PATCH v2 00/13] ARM: OMAP2+: AM43x PRCM support In-Reply-To: References: Message-ID: <521DE6F4.9060804@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hi Paul, On Wednesday 21 August 2013 08:23 AM, Paul Walmsley wrote: >> Currently there is no public TRM available for AM43x. > > Can you think of any way that the data can be doublechecked against some > reference or against the reality of the chip?
