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.
