Subject: [PATCHv3 12/27] ARM: OMAP2+: clock: add support for clkdm ops to the low level clk ops
Date: Mon, 25 May 2015 18:00:17 +0300 [thread overview]
Message-ID: <1432566032-10860-13-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1432566032-10860-1-git-send-email-t-kristo@ti.com>
Clock driver requires access to certain clockdomain handling ops once
the code is being moved over under clock driver. Example of this is
clk_enable / clk_disable under omap3 DPLL code. The required clkdm
APIs are now exported through the ti_clk_ll_ops struct.
