ARM: OMAP2+: CM: make some pointers and function arguments as const Make the pointer cm_ll_data of type cm_ll_data as const as it does not modify the fields of the structure it points too. After this change, make the argument of cm_register function as const as it is used to initialise cm_ll_data or used inside an if condition. Make the pointer argument of cm_unregister function as const as it is only used inside an if condition. Add const to the function prototypes too.

ARM: OMAP2+: CM: add support for getting phys address for a clkctrl register Add a new CM API for fetching the physical address of a hwmod clkctrl register. This is needed to map omap hwmods against clkctrl clocks, the existing support for clkdm address translation was not sufficient to handle the mutant cases where the clockdomain offset is completely off from the clkctrl ones.

ARM: OMAP2/3: CM: fix cm_split_idlest functionality cm_split_idlest doesn't take the CM base offset into account right now, causing it to read reserved registers which show idlestatus as active always. This will cause the wait_module_ready functionality to be effectively an expensive NOP, which will cause problems if the module hasn't really activated during its execution. Fix by adding the CM offset into the calculation so the wait_module_ready will access correct register.

clk: ti: convert to use proper register definition for all accesses Currently, TI clock driver uses an encapsulated struct that is cast into a void pointer to store all register addresses. This can be considered as rather nasty hackery, and prevents from expanding the register address field also. Instead, replace all the code to use proper struct in place for this, which contains all the previously used data. This patch is rather large as it is touching multiple files, but this can't be split up as we need to avoid any boot breakage.

ARM: OMAP2+: CM/clock: convert _omap2_module_wait_ready() to use SoC-independent CM functions Convert the OMAP clock code's _omap2_module_wait_ready() to use SoC-independent CM functions that are provided by the CM code, rather than using a deprecated function from mach-omap2/prcm.c. This facilitates the future conversion of the CM code to a driver, and also removes a mach-omap2/prcm.c user. mach-omap2/prcm.c will be removed by a subsequent patch. Some modules have IDLEST registers that aren't in the CM module, such as the AM3517 IDLEST bits. So we also need a fallback function for these non-CM odd cases. Create a temporary one in mach-omap2/clock.c, intended to exist until the SCM drivers are ready. Signed-off-by: Paul Walmsley <paul@pwsan.com> Tested-by: Vaibhav Hiremath <hvaibhav@ti.com>

ARM: OMAP2+: CM: prepare for use of cm_ll_data function pointers There are several CM operations which behave similarly across OMAP2+ SoCs, but which have slight differences in their underlying implementations. This patch creates the support code for this function pointer registration process. No function pointers are included yet, but a subsequent patch will create these for the module IDLEST registers. This patch allows other code to use CM-provided data and operations without needing to know which SoC is currently in use. A further description of the concept is provided in the patch entitled "ARM: OMAP2+: PRM: prepare for use of prm_ll_data function pointers". Signed-off-by: Paul Walmsley <paul@pwsan.com>
