-I) Overview
------------
-
-  1) Actual state
-  ---------------
-
-  At this moment power doesn't contain API. There are many methods for
-  initialization of some board specific functions but only few does what is
-  expected. Basically only one file contains something meaningful for this
-  driver.
-
-  2) Current implementation
-  -------------------------
-
-  In file twl6030.c are methods twl6030_stop_usb_charging() and
-  twl6030_start_usb_charging() for start and stop charging from USB. There are
-  also methods to get information about battery state and initialization of
-  battery charging. Only these methods are used in converted API.
-
-
-II) Approach
-------------
-
-  1) New API
-  ----------
-
-  New API implements only functions specific for managing power. All board
-  specific init methods are moved to other files. Name of methods are
-  self-explanatory.
-
-  struct ops {
-    void (*start_usb_charging)(struct instance *i);
-    void (*stop_usb_charging)(struct instance *i);
-    int  (*get_battery_current)(struct instance *i);
-    int  (*get_battery_voltage)(struct instance *i);
-    void (*init_battery_charging)(struct instance *i);
-  }
-
-  2) Conversions of other methods
-  -------------------------------
-
-  Methods that can't be converted to new API are moved to board file or to
-  special file for board hacks.
-
-III) Analysis of in-tree drivers
---------------------------------
-
-  ftpmu010.c
-  ----------
-  All methods of this file are moved to another location.
-    void ftpmu010_32768osc_enable(void): Move to boards hacks
-    void ftpmu010_mfpsr_select_dev(unsigned int dev): Move to board file
-						      arch/nds32/lib/board.c
-    void ftpmu010_mfpsr_diselect_dev(unsigned int dev): Dead code
-    void ftpmu010_dlldis_disable(void): Dead code
-    void ftpmu010_sdram_clk_disable(unsigned int cr0): Move to board file
-						       arch/nds32/lib/board.c
-    void ftpmu010_sdramhtc_set(unsigned int val): Move to board file
-						  arch/nds32/lib/board.c
-
-  twl4030.c
-  ---------
-  All methods of this file are moved to another location.
-    void twl4030_power_reset_init(void): Move to board hacks
-    void twl4030_pmrecv_vsel_cfg(u8 vsel_reg, u8 vsel_val, u8 dev_grp,
-				 u8 dev_grp_sel): Move to board hacks
-    void twl4030_power_init(void): Move to board hacks
-    void twl4030_power_mmc_init(void): Move to board hacks
-
-  twl6030.c
-  ---------
-  Some methods are converted to new API and rest are moved to another location.
-    void twl6030_stop_usb_charging(void): Convert to new API
-    void twl6030_start_usb_charging(void): Convert to new API
-    int twl6030_get_battery_current(void): Convert to new API
-    int twl6030_get_battery_voltage(void): Convert to new API
-    void twl6030_init_battery_charging(void): Convert to new API
-    void twl6030_power_mmc_init(): Move to board file
-				   drivers/mmc/omap_hsmmc.c
-    void twl6030_usb_device_settings(): Move to board file
-					drivers/usb/musb/omap3.c
