Subject: [PATCH 1/4] ARM: OMAP4+: hwmod: Add hwmod flag for HWMOD_OMAP4_ZERO_CLKCTRL_OFFSET
Date: Tue, 12 Jul 2016 12:50:31 -0500 [thread overview]
Message-ID: <20160712175034.743-2-d-gerlach@ti.com> (raw)
In-Reply-To: <20160712175034.743-1-d-gerlach@ti.com>
Nearly all modules on OMAP4 and newer platforms have clkctrl offsets
that are non-zero except for the RTC on am335x. Because we rely on a
clkctrl_offset of zero to indicate no clkctrl_offset being present,
lets add a HWMOD_OMAP4_ZERO_CLKCTRL_OFFSET flag to use to indicate
hwmods that have a valid clkctrl_offset of 0.
