Hello,
This patch series implements the first public version of the
omap_hwmod hardware module layer. It manages on-chip hardware IP
blocks, and provides a means for defining their integration
properties to the rest of the chip. Some of the major goals here
are to collect all IP block integration data into one place, and
to put devices in a known state at boot.
As an exemplar, this series also implements the basic omap_hwmod
structures for HSMMC1/2/3 on OMAP2430 and OMAP34xx.
The omap_hwmod code is initially intended for use with OMAP2+
chips. The goal is to auto-generate these structures for OMAP4
from a TI hardware database export. OMAP2/3 structures will
probably have to be filled in by hand.
The series starts with several prerequisite patches. OMAP1 and OMAP2
MMC core initialization code is split from plat-omap/devices.c into
mach-omap1/devices.c and mach-omap2/devices.c. Several clock
framework fixes are also required. Finally the omap_hwmod code
and header file are created; they are integrated with the system boot
process, and then the MMC example files are added.
More detailed descriptions are found in each individual patch
description.
Boot-tested on OMAP3 Beagle and 3430SDP. Compile-tested on 2430SDP and
N800.
Comments welcome and solicited.
- Paul

Paul Walmsley (8):
OMAP2430/34xx HSMMC: add basic omap_hwmod entries for OMAP2430/34xx
OMAP: omap_hwmod: call omap_hwmod initialization at boot
OMAP2/3/4: create omap_hwmod layer
OMAP2/3/4 PRCM: add module IDLEST wait code
OMAP clock: associate MPU clocks with the mpu_clkdm
OMAP2/3 clock: ensure each clock has a unique name
OMAP clock: add omap_clk_get_by_name()
OMAP2/3 board-*.c files: read bootloader configuration earlier
