OMAP2/3 clock: split, rename omap2_wait_clock_ready() Some OMAP2/3 hardware modules have CM_IDLEST attributes that are not handled by the current omap2_wait_clock_ready() code. In preparation for patches that fix the unusual devices, rename the function omap2_wait_clock_ready() to omap2_wait_module_ready() and split it into three parts: 1. A clkops-specific companion clock return function (by default, omap2_clk_dflt_find_companion()) 2. A clkops-specific CM_IDLEST register address and bit shift return function (by default, omap2_clk_dflt_find_idlest()) 3. Code to wait for the CM to indicate that the module is ready (omap2_cm_wait_idlest()) Clocks can now specify their own custom find_companion() and find_idlest() functions; used in subsequent patches.

The code also uses gpmc_fck instead of it's parent clock core_l3_ck for GPMC clock. The H4 board file also adds h4_init_flash() function, which specify the flash start and end addresses.

OMAP4: PRCM: reorganize existing OMAP4 PRCM header files Split the existing cm44xx.h file into cm1_44xx.h and cm2_44xx.h files so they match their underlying OMAP hardware modules. Add clockdomain offset information. Add header files for the MPU local PRCM, prcm_mpu44xx.h, and for the SCRM, scrm44xx.h. SCRM register offsets still need to be added; TI should do this. Move the "_MOD" macros out of the prcm-common.h header file, into the header file of the hardware module that they belong to. For example, OMAP4430_PRM_*_MOD macros have been moved into the prm44xx.h header. Adjust #includes of all files that used the old PRCM header file names to point to the new filenames. The autogeneration scripts have been updated accordingly.

OMAP: control: move plat-omap/control.h to mach-omap2/control.h Only OMAP2+ platforms have the System Control Module (SCM) IP block. In the past, we've kept the SCM header file in plat-omap. This has led to abuse - device drivers including it; includes being added that create implicit dependencies on OMAP2+ builds; etc. In response, move the SCM headers into mach-omap2/. As part of this, remove the direct SCM access from the OMAP UDC driver. It was clearly broken. The UDC code needs an indepth review for use on OMAP2+ chips.

omap: pass the reboot command to the boot loader This patch follows the commit be093beb608edf821b45fe00a8a080fb5c6ed4af by Russell King: OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). The patch adds the missing parameter to omap1_arch_reset() and omap_prcm_arch_reset(), and modifies the latter to pass the reboot command parameter to the boot loader instead of reboot mode (which is for kernel internal use only and cannot be modified by the userspace).

Note that board-*.c files change GPMC (General Purpose Memory Controller) access to use gpmc_cs_write_reg() instead of accessing the registers directly. The code also uses gpmc_fck instead of it's parent clock core_l3_ck for GPMC clock. The H4 board file also adds h4_init_flash() function, which specify the flash start and end addresses.

OMAP4: PRCM: rename _MOD macros to _INST Back in the OMAP2/3 PRCM interface days, the macros that referred to the offsets of individual PRM/CM instances from the top of the PRM/CM hardware modules were incorrectly suffixed with "_MOD". (They should have been suffixed with something like "_INST" or "_INSTANCE".) These days, now that we have better contact with the OMAP hardware people, we know that this naming is wrong. And in fact in OMAP4, there are actual hardware module offsets inside the instances, so the incorrect naming gets confusing very quickly for anyone who knows the hardware. Fix this naming for OMAP4, before things get too far along, by changing "_MOD" to "_INST" on the end of these macros. So, for example, OMAP4430_CM2_INSTR_MOD becomes OMAP4430_CM2_INSTR_INST. This unfortunately creates quite a large diff, but it is a straightforward rename. This patch should not result in any functional changes. The autogeneration scripts have been updated accordingly.

OMAP2/3 clock: Extend find_idlest() to pass back idle state value Current implementation defines clock idle state indicators based on the cpu information (cpu_is_omap24xx() or cpu_is_omap34xx()) in a system wide manner. This patch extends the find_idlest() function in clkops to pass back the idle state indicator for that clock, thus allowing idle state indicators to be defined on a per clock basis if required. This is specifically needed on AM35xx devices as the new IPSS clocks indicates the idle status (0 is idle, 1 is ready) in a way just opposite to how its handled in OMAP3 (0 is ready, 1 is idle).

OMAP2/3 clock: split, rename omap2_wait_clock_ready() Some OMAP2/3 hardware modules have CM_IDLEST attributes that are not handled by the current omap2_wait_clock_ready() code. In preparation for patches that fix the unusual devices, rename the function omap2_wait_clock_ready() to omap2_wait_module_ready() and split it into three parts: 1. A clkops-specific companion clock return function (by default, omap2_clk_dflt_find_companion()) 2. A clkops-specific CM_IDLEST register address and bit shift return function (by default, omap2_clk_dflt_find_idlest()) 3. Code to wait for the CM to indicate that the module is ready (omap2_cm_wait_idlest()) Clocks can now specify their own custom find_companion() and find_idlest() functions; used in subsequent patches.
