c23ac90f78 [media] c8sectpfe: Rework firmware loading mechanism
c8sectpfe driver relied on CONFIG_FW_LOADER_USER_HELPER_FALLBACK option
for loading its xp70 firmware. A previous commit removed this Kconfig
option, as it is apparently harmful, but did not update the driver
code which relied on it.

This patch reworks the firmware loading into the start_feed callback.
At this point we can be sure the rootfs is present, thereby removing
the depedency on CONFIG_FW_LOADER_USER_HELPER_FALLBACK.

Fixes: 79f5b6ae96 ('[media] c8sectpfe: Remove select on CONFIG_FW_LOADER_USER_HELPER_FALLBACK')

a6311d2751 [media] c8sectpfe: Fix broken circular buffer wp management
During the review process, a regression was intoduced in the
circular buffer write pointer management. This means that wp
doesn't get managed properly once the buffer becomes full.

ff628a4dbd Device tree auxdata handling fix that allows a match based on the
compatible string if no exact match based on the IO address is found.
 
 This leaves out the need to patch auxdata for each driver when adding
 new SoCs. And it also reprotedly fixes the issue of passing auxdata
 to a child if the parent instantiates the child from DT as discussed
 in the "[PATCH] of/platform: Allow secondary compatible match in
 of_dev_lookup" mailing list thread.
 
 As a minimal use case, let's also convert omap pinctrl auxdatato
 use a generic match.
 
 There is no need to get this in to the v4.6-rc cycle and it can wait
 for v4.7 merge window. Note that these changes have now been sitting
 in Linux next for about two weeks so far as I wanted to make sure no
 new issues are popping up.

11c3aead82 Legacy booting vs device tree booting fixes for omaps for
v4.7 merge window. These are not considered urgent fixes enough
 for the v4.6-rc cycle, but we need them in v4.7 in order to drop
 the last remaining board-*.c files for omap3 for v4.8 merge window.
 
 On Nokia N900, we need to pass the MMC slot names for the legacy
 user space to work. Let's do that using auxdata as the driver is
 setting up things already with the pdata for legacy booting. Then
 we can later on discuss if we may want to have some generic binding
 describing where the MMC slots are on the device.
 
 N900 also has had the ir-rx51 device driver unusable with multiarch
 for a long time. Let's pass the dmtimer data in pdata for the driver
 to get it going again. Then once things are working, we can eventually
 change the driver to use just hrtimer and PWM framework. The driver
 changes will be queued separately.

5420f9fd15 arm-ccn: Enable building as module
arm-ccn driver uses irq_set_affinity, which is not exported and
hence cannot be built as a module, eventhough we have all the
bits ready. This patch makes use of the exported helper
irq_set_affinity_hint() instead. Also, the __free_irq expects
the affinity_hint to be NULL when we free the irq. So set the
affinity_hint to NULL at clean up.

Now that we can build it as a module, update the Kconfig to
reflect the change.

Merge tag 'aspeed-for-4.7-arch' of https://github.com/shenki/linux into next/soc

Merge "aspeed arch tag for 4.7" from Joel Stanley <joel@jms.id.au>:

This is the initial pull request for the Aspeed BMC SoCs.

I put 4.7 in the subject for this and the subsequent requests but if it's a bit
late in the cycle then I understand.

Following review I got rid of the board file by pushing the functionality out
to a watchdog and clock driver, so it's just the Kconfig bits. I've also added
myself to maintainers for the Aspeed arch and drivers as I intend on looking
after them.

2377f9fdac MAINTAINERS: add ARM/NXP LPC32XX SoC specific drivers to the section
The change adds a list of files for maintenance under NXP LPC32xx
section, the listed files are NXP LPC32xx SoC series mach files,
DTS files of NXP LPC32xx SoC powered boards and NXP LPC32xx SoC
peripheral drivers, most of the peripheral driver file names match
'lpc32xx' pattern.

8d5a6b42ff MAINTAINERS: add new maintainers of NXP LPC32xx SoC
Roland Stigge added initial support of NXP LPC32xx SoC series and
first boards powered by it, but for a while since v3.18-rc1 the
SoC support is unmaintained and became stale.

Vladimir Zapolskiy and Sylvain Lemieux expressed interest in
continuation of NXP LPC32xx maintenance, reflect this in MAINTAINERS
record file for better communication with Linux kernel community.

15e4f7daf3 MAINTAINERS: move ARM/NXP LPC32xx record to ARM section
A record of NXP LPC32xx SoC support is lost between LMxx hwmon drivers
and lockdep, rename and move it to a place where all other ARM
SoC and machines settle.

Note, NXP LPC32xx maintenance is actually about SoC series itself, SoC
peripherals and a number of machines powered by LPC32xx SoC, so while
we are here correct the title name to emphasize that the maintenance
concerns SoC support in general.

Only increment the TX counters in the irq handler if a CAN message
was sent. The current code incremented the counters also if the TX

be1861320a can: ifi: Update timing configuration code
The updated documentation regarding the IFI CANFD core from April 2016
adds more details regarding the timing calculation. There is no longer
any distinction in the timing calculation between CANFD and CAN2.0, but
instead there are two timing modes -- 4_12_6_6 and 7_9_8_8 -- where the
numbers mean the width in bits of the SJW/Prescaler/TimeA/TimeB fields.
The code uses 7_9_8_8 mode, which allows more fine-grained control over
the timing.
