Subject: [PATCH 4/8] ARM: OMAP2+: PM: use the functional power states API
Date: Wed, 15 Aug 2012 12:02:44 +0200	[thread overview]
Message-ID: <1345024968-28951-5-git-send-email-j-pihet@ti.com> (raw)
In-Reply-To: <1345024968-28951-1-git-send-email-j-pihet@ti.com>

Use the functional power states as the API to control power
domains:
- use the PWRDM_FUNC_PWRST_* and PWRDM_LOGIC_MEM_PWRST_*
  macros for the power states and logic settings,
- the pwrdm_set_next_fpwrst function, which controls
  the power states and logic settings of power domains, shall
  be used instead of pwrdm_set_next_pwrst to program the power
  domains next states.

Note: the internal code for power domains state management still
uses the internal power states.
