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. Signed-off-by:

The OMAP watchdog timer IP blocks require a specific set of register writes to occur before they will be disabled[1], even if the device clocks appear to be disabled in the CM_*CLKEN registers. In the MPU watchdog case, failure to execute this reset sequence will eventually cause the watchdog to reset the OMAP unexpectedly. Previously, the code to disable this watchdog was manually called from mach-omap2/devices.c during device initialization. This causes the watchdog to be unconditionally disabled for a portion of kernel initialization. This should be controllable by the board-*.c files, since some system integrators will want full watchdog coverage of kernel initialization. Also, the watchdog disable code was not connected to the hwmod shutdown code. This means that calling omap_hwmod_shutdown() will not, in fact, disable the watchdog, and the goal of omap_hwmod_shutdown() is to be able to shutdown any on-chip OMAP device. To resolve the latter problem, populate the pre_shutdown pointer in the watchdog timer hwmod classes with a function that executes the watchdog shutdown sequence. This allows the hwmod code to fully disable the watchdog. Then, to allow some board files to support watchdog coverage throughout kernel initialization, add common code to mach-omap2/io.c to cause the MPU watchdog to be disabled on boot unless a board file specifically requests it to remain enabled. Board files can do this by changing the watchdog timer hwmod's postsetup state between the omap2_init_common_infrastructure() and omap2_init_common_devices() function calls. 1.

The current version contains only the interconnects and the mpu hwmods. The remaining hwmods will be introduced by further patches on top of this one. - enable as well omap_hwmod.c build for OMAP4 Soc Please not that this file uses the new naming convention for naming HW IPs. This convention will be backported soon for previous OMAP2 & 3 data files. new name trm name ------------- ------------------- counter_32k synctimer_32k l3_main l3 timerX gptimerX / dmtimerX mmcX mmchsX / sdmmcX dma_system sdma smartreflex_X sr_X / sr? usb_host_fs usbfshost usb_otg_hs hsusbotg usb_tll_hs usbtllhs_config wd_timerX wdtimerX ipu cortexm3 / ducati dsp c6x / tesla iva ivahd / iva2.2 kbd kbdocp / keyboard mailbox system_mailbox mpu cortexa9 / chiron Signed-off-by:
