Allows dumping out current register contents from the debug filesystem, and also allows user to add arbitrary register save points into code. 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:

Peter 'p2' De Schrijver authored
This patch provides the debugfs entries and a function which will be called by the PM code to register the time spent per domain per state. 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 authored
This patch provides the infrastructure to count how many times a powerdomain entered a given power state (on, inactive, retention, off). A number of functions are provided which will be called by the chip specific powerdomain and clockdomain code whenever a transition might have happened. Signed-off-by:

This patch uses kmalloc(size,GFP_ATOMIC) instead of kmalloc(size,GFP_KERNEL) to allocate memory for instance of struct power_state in pwrdms_setup(), since it may be called by pwrdm_for_each() with irq disabled. 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:

In usb_musb_pm_init, we attempt to access an MUSB register when the i-clock may not be on, or the module is otherwise not accessible. 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:

Second reason of OMAP4 boot failure on 2.6.31.rc6, the UART platform data is not getting registered to kernel. 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. Signed-off-by:

After the patch series "[PATCH 00/14] OMAP PM fixes for .31-rc" merge in 2.6.31-rc5, the kernel crashed during boot on OMAP4430. 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. Some more info on the merge issue can be found here. More info- http://lkml.org/lkml/2009/8/20/192 Note: While merging this patch,"IO_ADDRESS" needs to be changed to "OMAP2_IO_ADDRESS" if the Tony's below series is already merged in. http://www.mail-archive.com/linux-omap@vger.kernel.org/msg15072.htmlSigned-off-by:

OMAP tags are deprecrated so drop them. Drop UART config data which decides which UARTs to enable during boot. This is no longer necessary since serial core code disables clocks after inactivity. Background: with new UART idle code, all on-chip UARTs are idled using a configurable inactivity timer (default 5 seconds.) After the inactivity timer, UART clocks are disabled automatically.

The root cause is a duplicate section name (.text); is this legal? [ Amerigo Wang: "AFAIK, yes." ] However, there's a problem with commit 6d760133 in that if you fail to allocate a mod->sect_attrs (in this case it's null because of the duplication), it still gets used without checking in add_notes_attrs() This should fix it [ This patch leaves other problems, particularly the sections directory, but recent parisc toolchains seem to produce these modules and this prevents a crash and is a minimal change -- RR ] Signed-off-by:
