f31b1001e1 Merge "pinctrl: qcom: spmi-gpio: Add support for GPIO LV/MV subtype" 2016-09-11 23:19:13 -07:00
Stephen Boyd
11f95b1a64 driver-core: platform: Add platform_irq_count()
A recent patch added calls to of_irq_count() in the qcom pinctrl
drivers and that caused module build failures because
of_irq_count() is not an exported symbol. We shouldn't export
of_irq_count() to modules because it's an internal OF API that
shouldn't be used by drivers. Platform drivers should use
platform device APIs instead. Therefore, add a platform_irq_count()
API that mirrors the of_irq_count() API so that platform drivers
can stay DT agnostic.

5ab1e18aa3 Revert "Merge remote-tracking branch 'msm-4.4/tmp-510d0a3f' into msm-4.4"
This reverts commit 9d6fd2c3e9 ("Merge remote-tracking branch
'msm-4.4/tmp-510d0a3f' into msm-4.4"), because it breaks the
dump parsing tools due to kernel can be loaded anywhere in the memory
now and not fixed at linear mapping.

There is a possibility of deadlock while doing late

memblock_is_memory can be called from irq context thus
trying to claim seqlock again. Following call stack was

Fix it by disabling irqs during late memblock
configuration. It is a one time operation which changes
memblock related data structures and doesn't carry
performance impact.

commit dec8e8f6e6504aa3496c0f7cc10c756bb0e10f44 upstream.

Specifically for the case of reads that use the Extended Register
Read Long command, a multi-byte read operation is broken up into
8-byte chunks.  However the call to spmi_ext_register_readl() is
incorrectly passing 'val_size', which if greater than 8 will
always fail.  The argument should instead be 'len'.

c1fa88dd6d regmap: improve debugfs interface to dump specific addresses
The current method of cat-ing register file dumps the entire
address space. One can use dd command to dump a subrange within
the address space. However one needs to know the string length
of each line which is derived from max address, the character
length of each register entry and the format.

Provide simple means to dump a range by allowing user to specify
the start address and the count of registers. When the data is read
convert the dump address to a starting position in the file. Similarly
if the file offset goes beyond the dump range return 0 to indicate
that the data is already dumped.

Also provide means to write to a register address.

cab4c949ad PM / Domains: Fix removal of a subdomain
commit beda5fc1ff9b527059290a97b672d2ee0eb7b92f upstream.

Commit 30e7a65b3f (PM / Domains: Ensure subdomain is not in use
before removing) added a test to ensure that a subdomain is not a
master to another subdomain or if any devices are using the subdomain
before removing. This change incorrectly used the "slave_links" list to
determine if the subdomain is a master to another subdomain, where it
should have been using the "master_links" list instead. The
"slave_links" list will never be empty for a subdomain and so a
subdomain can never be removed. Fix this by testing if the
"master_links" list is empty instead.

dabe14168a PM / OPP: Initialize u_volt_min/max to a valid value
commit c88c395f4a6485f23f81e385c79945d68bcd5c5d upstream.

We kept u_volt_min/max initialized to 0, when only the target voltage is
present in DT, instead of the target/min/max triplet.

This didn't go well with the regulator framework, as on few calls the
min voltage was set to target and max was set to 0 and so resulted in a
kernel crash like below:

811cd7442b PM / OPP: Rename structures for clarity
Stephen pointed out recently, that few structures always confuse him as
they aren't named properly. And this patch tries to address that:

Names are updated as:
- device_opp or dev_opp -> opp_table
- dev_opp_list -> opp_tables
- dev_opp_list_lock -> opp_table_lock
- device_list_opp -> opp_device (it was never a list, but a structure)
- list_dev -> opp_dev
- And similar changes in comments and function names as well.

This also fixes checkpatch warnings that were generated with this patch.

No functional changes.

da978b6ea8 PM / OPP: Initialize regulator pointer to an error value
We are currently required to do two checks for regulator pointer:
IS_ERR() and IS_NULL().

And multiple instances are reported, about both of these not being used
consistently and so resulting in crashes.

Fix that by initializing regulator pointer with an error value and
checking it only against an error.

This makes code more consistent and more efficient.

ed34315548 PM / OPP: Fix NULL pointer dereference crash when disabling OPPs
Commit 7d34d56ef334 (PM / OPP: Disable OPPs that aren't supported by
the regulator) causes a crash to happen on Tegra124 Jetson TK1 when
using the DFLL clock source for the CPU.  The DFLL manages the voltage
itself and so there is no regulator specified for the OPPs and so we
get a crash when we try to dereference the regulator pointer.  Fix
this by checking to see if the regulator IS_ERR_OR_NULL before
dereferencing it.

This adds a routine, dev_pm_opp_set_rate(), responsible for configuring

The OPP is found by matching against the target_freq passed to the
routine. This shall replace similar code present in most of the OPP

df8ba0ff4a PM / OPP: Parse clock-latency and voltage-tolerance for v1 bindings
V2 bindings have better support for clock-latency and voltage-tolerance
and doesn't need special care. To use callbacks, like
dev_pm_opp_get_max_{transition|volt}_latency(), irrespective of the
bindings, the core needs to know clock-latency/voltage-tolerance for the
earlier bindings.

This patch reads clock-latency/voltage-tolerance from the device node,
irrespective of the bindings (to keep it simple) and use them only for
V1 bindings.

59dfbb981e PM / OPP: Use snprintf() instead of sprintf()
sprintf() can access memory outside of the range of the character array,
and is risky in some situations. The driver specified prop_name string
can be longer than NAME_MAX here (only an attacker will do that though)
and so blindly copying it into the character array of size NAME_MAX
isn't safe. Instead we must use snprintf() here.

0871a32c4d PM / OPP: Add debugfs support
This patch adds debugfs support to OPP layer to export OPPs and their
properties for all the devices.

This creates a top level directory: /sys/kernel/debug/opp and then
device specific directories (based on device names) inside it. For
example: 'cpu0', 'cpu1', etc..

If multiple devices share the OPP table, then the real directory is
created only for the first device. For all others, links are created to
the real directory.

Inside the device specific directory, a separate directory is created
for each OPP. And within that files per opp property.

2f879b6dcb mm/memblock: fix a race between search and remove
no-map-fixup feature for dma-removed reserve region does a
late memblock remove. This late removal is a slight
deviation from conventional memblock flow. That leads to a
race between pfn_valid->memblock_search, and
memblock_remove.

To fix this, use a read seqlock in memblock_search, which
would ensure minimum overhead in search path. And export
two APIs to let code doing late memblock remove apply
write seqlock. write seqlock would ensure that search
retries if the list is updated concurrently.

The two exported APIs which should be called before
and after modifying memblock regions, late in boot, are
   - memblock_region_resize_late_begin
   - memblock_region_resize_late_end

The code to alter memblock regions should be guarded by
these APIs.
