* omap: headers: Move remaining headers from include/mach to include/platTony Lindgren2009-10-2055-7696/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the remaining headers under plat-omap/include/mach to plat-omap/include/plat. Also search and replace the files using these headers to include using the right path.

| | | | | | | | | | | | | | | Earlier patch "omap: Remap L3, L4 to get more kernel io address space" changed the VMALLOC_END. However, this change causes problems on mach-omap1: BUG: mapping for 0xe0000000 at 0xe0000000 overlaps vmalloc space BUG: mapping for 0xe1000000 at 0xe1000000 overlaps vmalloc space Fix this by creating separate vmalloc.h files for mach-omap1 and mach-omap2.

| | | | | | | | | | | | | | This patch remap L3 and L4 io space to get more kernel address space. With this patch, 512 MB of IO space is reclaimed. Some more combinations are possible but to make it uniform across OMAP24XX, OMAP34XX and OMAP4430, these io combinations are chosen Once this is reviewed and tested sufficiently, a documentation entry can be created to ease up reading and debugging.

* omap: Split OMAP2_IO_ADDRESS to L3 and L4Santosh Shilimkar2009-10-194-14/+19
| | | | | | | | | | | | | | | This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and OMAP2_L4_IO_ADDRESS to reclaim more IO space. The omap_read*() and omap_write*() functions will work only over L4 address space. Current omap kernel stack uses these functions only to access registers over L4 io address space Note that these macros should only be used when ioremap does not work.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PM dynamic OFF state results in context loss. That is, the host controller has been powered off at some point, which means the registers have been reset. The driver must detect when this happens, and restore the context. This patch adds the means to detect context loss. Note, the PM side is not yet implemented.

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.

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 earlierPaul Walmsley2009-09-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Also some new fields are added to the powerdomain struct to keep the time information. NOTE: As of v2.6.29, using getnstimeofday() after drivers are suspended is no longer safe since the timekeeping subsystem is also suspended as part of the suspend process. Instead use sched_clock() which on OMAP returns the 32k SYNC timer in nanoseconds.
