      OMAP2/3/4 core: create omap_device layer · b04b65ab
      由 Paul Walmsley 提交于 
      The omap_device code provides a mapping of omap_hwmod structures into
the platform_device system, and includes some details on external
(board-level) integration.  This allows drivers to enable, idle, and
shutdown on-chip device resources, including clocks, regulators, etc.
The resources enabled and idled are dependent on the device's maximum
wakeup latency constraint (if present).

At the moment, omap_device functions are intended to be called from
platform_data function pointers.  Ideally in the future these
functions will be called from either subarchitecture-specific
platform_data activate, deactivate functions, or via an custom
bus/device type for OMAP.

      OMAP2/3/4: create omap_hwmod layer · 63c85238
      由 Paul Walmsley 提交于 
      OMAP SoCs can be considered a collection of hardware IP blocks
connected by various interconnects.  The bus topology and device
integration data is somewhat more complex than platform_device can
encode.  This patch creates code and structures to manage information
about OMAP on-chip devices ("hardware modules") and their integration
to the rest of the chip.  Hardware module data is intended to be
generated dynamically from the TI hardware database for the OMAP4
chips and beyond, easing Linux support for new chip variants.

This code currently:

- resets and configures all hardware modules upon startup, reducing bootloader
  dependencies;

- provides hooks for Linux driver model code to enable, idle, and shutdown
  hardware modules (forthcoming patch);

- waits for hardware modules to leave idle once their clocks
  are enabled and OCP_SYSCONFIG bits are set appropriately.

- provides a means to pass arbitrary IP block configuration data (e.g.,
  FIFO size) to the device driver (via the dev_attr void pointer)

In the future this code is intended to:

- estimate interconnect bandwidth and latency characteristics to
  ensure constraints are satisfied during DVFS

- provide *GRPSEL bit data to the powerdomain code

- handle pin/ball muxing for devices

- generate IO mapping information dynamically

- supply device firewall configuration data

- provide hardware module data to other on-chip coprocessor software

- allow the removal of the "disable unused clocks" code in the OMAP2/3
  clock code

This patch represents a collaborative effort involving many people from TI,
Nokia, and the Linux-OMAP community.

      OMAP2/3 board-*.c files: read bootloader configuration earlier · b3c6df3a
      由 Paul Walmsley 提交于 
      Most board-*.c files read configuration data from the bootloader in
their .init_machine() function.  This needs to happen earlier, at some
point before omap2_init_common_hw() is called.  This is because a
future patch will use the bootloader serial console port information
to enable the UART clocks earlier, immediately after omap2_clk_init().
This is in turn necessary since otherwise clock tree usecounts on
clocks like dpll4_m2x2_ck will be bogus, which can cause the
currently-active console UART clock to be disabled during boot.

      OMAP2/3 PM: create the OMAP PM interface and add a default OMAP PM no-op layer · c0407a96
      由 Paul Walmsley 提交于 
      The interface provides device drivers, CPUFreq, and DSPBridge with a
means of controlling OMAP power management parameters that are not yet
supported by the Linux PM PMQoS interface.  Copious documentation is
in the patch in Documentation/arm/OMAP/omap_pm and the interface
header file, arch/arm/plat-omap/include/mach/omap-pm.h.

Thanks to Rajendra Nayak <rnayak@ti.com> for adding CORE (VDD2) OPP
support and moving the OPP table initialization earlier in the event
that the clock code needs them.  Thanks to Tero Kristo
<tero.kristo@nokia.com> for fixing the parameter check in
omap_pm_set_min_bus_tput().  Jouni signed off on Tero's patch.
