Note that for 594MHz device the transfer mode is limited to UDMA4 since ideclk rate is less than 100 MHz, which forces udma_mask in palm_bk3710.c to UDMA4, while for 729MHz device, it is UDMA5.

An example snippet and error snapshot is listed below. Following code in mach/io.h: #define inl(p) my_inl() static inline unsigned int my_inl(unsigned int addr) { if (IS_PCI_IO(addr)) return pci_inl (); else return le32_to_cpu(__raw_readl(__typesafe_io(addr))); } leads to error: LD arch/arm/boot/compressed/vmlinux arch/arm/boot/compressed/misc.o: In function `my_inl': misc.c:(.text+0x2744): undefined reference to `pci_inl' make[2]: *** [arch/arm/boot/compressed/vmlinux] Error 1 This is because mach/io.h gets included in arch/arm/boot/compressed/misc.c through mach/serial.h but pci.c file, which defines 'pci_inl' doesn't get built into compressed vmlinux.

This now uses some runtime infrastructure, keyed off that new soc_info field, which doesn't handle irq_to_gpio(). - Provide a new irq_chip ... GPIO IRQs handled directly by AINTC still need edge triggering managed by the GPIO controller. DM365 chips no longer falsely report 104 GPIO IRQs as they boot. Intelligence about IRQ muxing is missing, so for the moment this only exposes the first eight DM365 GPIOs, which are never muxed. The next eight are muxed, half with Ethernet (which uses most of those pins anyway). Tested on DM355 (10 unbanked IRQs _or_ 104 banked ones) and also on DM365 (16 unbanked ones, only 8 made available).

Since its so similar to davinci, put the support for the da830 in the same directory as the davinci code. There are differences, however. Some of those differences prevent support for davinci and da830 platforms to work in the same kernel binary. Those differences are: 1) Different physical address for RAM. This is relevant to Makefile.boot addresses and PHYS_OFFSET. The Makefile.boot issue isn't truly a kernel issue but it means u-boot won't work with a uImage including both architectures. The PHYS_OFFSET issue is addressed by the "Allow for runtime-determined PHYS_OFFSET" patch by Lennert Buytenhek but it hasn't been accepted yet. 2) Different uart addresses. This is only an issue for the 'addruart' assembly macro when CONFIG_DEBUG_LL is enabled. Since the code in that macro is called so early (e.g., by _error_p in kernel/head.S when the processor lookup fails), we can't determine what platform the kernel is running on at runtime to use the correct uart address. These areas have compile errors intentionally inserted to indicate to the builder they're doing something wrong. A new config variable, CONFIG_ARCH_DAVINCI_DMx, is added to distinguish between a true davinci architecture and the da830 architecture. Note that the da830 currently has an issue with writeback data cache so CONFIG_CPU_DCACHE_WRITETHROUGH should be enabled when building a da830 kernel.

Modify the edma_alloc_slot function to take an extra argument for the controller. Also update ASoC drivers to use API. ASoC changes Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> - Move queue related mappings to dm<soc>.c EDMA in DM355 and DM644x has two transfer controllers while DM646x has four transfer controllers. Moving the queue to tc mapping and queue priority mapping to dm<soc>.c will be helpful to probe these mappings from platform device so that the machine_is_* testing will be avoided. - add channel mapping logic Channel mapping logic is introduced in dm646x EDMA. This implies that there is no fixed association for a channel number to a parameter entry number. In other words, using the DMA channel mapping registers (DCHMAPn), a PaRAM entry can be mapped to any channel. While in the case of dm644x and dm355 there is a fixed mapping between the EDMA channel and Param entry number.

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.

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.

This has traditionally been implemented in the clock framework, but this is the wrong place for it: the clock framework doesn't know which module clocks must be enabled for a module to leave idle; and if a module is not in smart-idle mode, it may never leave idle at all. This type of information is best stored in a per-hardware module data structure (coming in a following patch), rather than a per-clock data structure. The new code will use these new functions to handle waiting for modules to enable. Once hardware module data is filled in for all of the on-chip devices, the clock framework code to handle IDLEST waiting can be removed. Signed-off-by: Paul Walmsley <paul@pwsan.com>

In fact the original code will just keep running past the struct to read who knows what in memory. This case manifests itself when from clkdms_setup() when enabling auto idle for a clock domain and the clockdomain usecount is greater than 0. When _clkdm_add_autodeps() tries to add the a dependency that does not exist in the powerdomain->wkdep_srcs array the for loop will run past the wkdep_srcs array. Currently in linux-omap you won't hit this because the not found case is never executed, unless you start modifying powerdomains and their wakeup/sleep deps.

Current register contents are available under debugfs at: [debugfs]/pm_debug/registers/current To add a save point, do following: From module init (or somewhere before the save call, called only once): pm_dbg_init_regset(n); // n=1..4, allocates memory for dump area #n From arbitrary code location: pm_dbg_regset_save(n); // n=1..4, saves registers to dump area #n After this, the register dump can be seen under [debugfs]/pm_debug/registers/n Signed-off-by: Tero Kristo <tero.kristo@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

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. Also, do not print out status for meta powerdomains (dpll*) Signed-off-by: Peter 'p2' De Schrijver <peter.de-schrijver@nokia.com> Signed-off-by: Tero Kristo <tero.kristo@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
