| * davinci: Fix watchdog reset codeDavid Griego2009-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | The davinci reset routine, davinci_watchdog_reset(), sets the TCR register instead of the TGCR register as it should to put the WDT into its "Initial State". It also writes the WDTCR register without the proper WDKEY which is pointless since the register will be write-protected. Signed-off-by: David Griego <dgriego@mvista.com> Signed-off-by: Mark A.

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.

| | * | OMAP2/3 board-*.c files: read bootloader configuration earlierPaul Walmsley2009-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * | OMAP2/3/4 PRCM: add module IDLEST wait codePaul Walmsley2009-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After a hardware module's clocks are enabled, Linux must wait for it to indicate readiness via its IDLEST bit before attempting to access the device, otherwise register accesses to the device may trigger an abort. 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>

| | * | OMAP: powerdomain: Fix overflow when doing powerdomain deps lookups.Paul Walmsley2009-09-03

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.

It is a easy fix for the following lockdep warning caused by kmalloc(size,GFP_KERNEL) in pwrdms_setup(): Power Management for TI OMAP3. ------------[ cut here ]------------ WARNING: at kernel/lockdep.c:2282 lockdep_trace_alloc+0xe8/0xfc() Modules linked in: [<c0032ccc>] (unwind_backtrace+0x0/0xec) from [<c0056934>] (warn_slowpath_common+0x48/0x60) [<c0056934>] (warn_slowpath_common+0x48/0x60) from [<c007da10>] (lockdep_trace_alloc+0xe8/0xfc) [<c007da10>] (lockdep_trace_alloc+0xe8/0xfc) from [<c00cd9bc>] (kmem_cache_alloc+0x28/0x178) [<c00cd9bc>] (kmem_cache_alloc+0x28/0x178) from [<c000f184>] (pwrdms_setup+0x30/0xf8) [<c000f184>] (pwrdms_setup+0x30/0xf8) from [<c00381c4>] (pwrdm_for_each+0x64/0x84) [<c00381c4>] (pwrdm_for_each+0x64/0x84) from [<c000ef60>] (omap3_pm_init+0x3f4/0x5ac) [<c000ef60>] (omap3_pm_init+0x3f4/0x5ac) from [<c002c2c0>] (do_one_initcall+0x30/0x1d4) [<c002c2c0>] (do_one_initcall+0x30/0x1d4) from [<c00088d8>] (kernel_init+0xa4/0x118) [<c00088d8>] (kernel_init+0xa4/0x118) from [<c002ddf8>] (kernel_thread_exit+0x0/0x8) ---[ end trace 1e06f8d97dc5a19b ]--- Signed-off-by: Ming Lei <tom.leiming@gmail.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

We need to either: - enable the clock before this access, or - remove this code and move it to the bootloader, or - enable the clock in the bootloader If we enable the clock in the bootloader, we might as well add the workaround in the bootloader itself. This code will anyway be changed once hwmod is in place, so remove it for now This allows us to boot the kernel on certain OMAP3 boards with a bootloader that doesn't enable this clock. Without this, we will need to upgrade the bootloaders on these boards. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that on-chip UARTs each have separate platform_data, the external UART needs an non-conflicting ID. Since there are 3 on-chip UARTs, the Zoom2 external UART will be registered after as the fourth.

Registration was failing because of clock check failure in omap_serial_init(). Below patch fix the same. OMAP4 clock framework patches are still getting discussed on mailing list so till then we need this.

This patch fixes it by adding UART4 support and related code. Without this patch omap_serial_init() would produce " NULL pointer dereference" and kernel crashes in the bootup on OMAP4430 platform.
