Use a mapping table (dpll_map) to match the possible system clock rates
to the appropriate DPLL parameters.
Introduce a function "omap_usb3_get_dpll_params()" that will
return the matching DPLL parameters for the given clock rate.
Also, bail out on phy init if DPLL locking fails.

Hi,
This iteration is in response to Namhyung's review of the previous
iteration. The differences are:
[3/5] adds a util/perl.h using #include_next without touching any
other files. This is a much cleaner approach.
[4/5] regenerates Context.c.
[5/5] is new. I just noticed it.
Thanks.

Wait for disabling all running kprobe handlers when a kprobe
event is disabled, since the caller, trace_remove_event_call()
supposes that a removing event is disabled completely by
disabling the event.
With this change, ftrace can ensure that there is no running
event handlers after disabling it.

LP8555 is one of LP855x family device.
This device needs pre_init_device() and post_init_device() driver structure.
It's same as LP8557, so the device configuration code is shared with LP8557.
Backlight outputs are generated from dual DC-DC boost converters.
It's configurable EPROM settings which
LP8501 can drive up to 9 channels like LP5523.
LEDs can be controlled directly via the I2C and programmable engines are

Chip specific data is defined in the structure, 'lp55xx_device_config'.

Why don't you set the matching order in the driver the way you want it

We need to active KEXEC for book3e and bypass or convert non-book3e stuff
in kexec coverage.

book3e is different with book3s since 3s includes the exception
vectors code in head_64.S as it relies on absolute addressing
which is only possible within this compilation unit. So we have
to get that label address with got.
And when boot a relocated kernel, we should reset ipvr properly again

This patch fixes a bug in pinctrl setup of serial2 device, Some of the
pins in the pinctrl node of serial2 do not belong to that
pin-controller. This patch divides them in the pins into there
respective pin controller nodes.
Without this patch serial on StiH416-B2000
Wait for disabling all running kprobe handlers when a kprobe
event is disabled, since the caller, trace_remove_event_call()
supposes that a removing event is disabled completely by
disabling the event.
With this change, ftrace can ensure that there is no running
event handlers after disabling it.
book3e have no real MMU mode so we have to create a 1:1 TLB
mapping to make sure we can access the real physical address.
And correct something to support this pseudo real mode on book3e.

We need to introduce a flag to indicate we're already running
a kexec kernel then we can go proper path. For example, We
shouldn't access spin_table from the bootloader to up any secondary
cpu for kexec kernel, and kexec kernel already know how to jump to
generic_secondary_smp_init.
This patchset is used to support kexec and kdump on book3e.
Tested on fsl-p5040 DS.
v3:
* add one patch to rename interrupt_end_book3e with __end_interrupts
then we can have a unique lable for book3e and book3s.
* add some comments for "book3e/kexec/kdump: enable kexec for kernel"
* clean
ppc64 kexec mechanism has a different implementation with ppc32.

Book3e is always aligned 1GB to create TLB so we should
use (KERNELBASE - MEMORY_START) as VIRT_PHYS_OFFSET to
get __pa/__va properly while boot kdump.

We can rename 'interrupt_end_book3e' with '__end_interrupts' then
book3s/book3e can share this unique label to make sure we can use
this conveniently.

Yeah, I will do that only. Don't resend anything for now.

Currently ftrace_open_generic_file gets an event_file from
inode->i_private, and then locks event_mutex and gets refcount.
However, this can cause a race as below scenario;

Currently, pciehp_resume will call pciehp_enable_slot() to add
device if there is a device in the slot. But if the device was
present before suspend, it's no necessary to add again. Now in
such case, there is some uncomfortable message like
pciehp :00:1c.1:pcie04: Device :03:00.0
Introduce PCIe Ext Capability Device Serial Number support,
so we can use the unique device serial number to identify
the physical device. During system suspend, if the PCIe
device was removed and inserted a new same device, after
system resume there is no good way to identify it, maybe
