brcmfmac: fix CLM load error for legacy chips when user helper is enabled
For legacy chips without CLM blob files, kernel with user helper function
returns -EAGAIN when we request_firmware(), and then driver got failed
when bringing up legacy chips. We expect the CLM blob file for legacy chip
is not existence in firmware path, but the -ENOENT error is transferred to
-EAGAIN in firmware_class.c with user helper.
Because of that, we continue with CLM data currently present in firmware
if getting error from doing request_firmware().

brcmfmac: add CLM download support
The firmware for brcmfmac devices includes information regarding
regulatory constraints. For certain devices this information is kept
separately in a binary form that needs to be downloaded to the device.
This patch adds support to download this so-called CLM blob file. It
uses the same naming scheme as the other firmware files with extension
of .clm_blob.
The CLM blob file is optional. If the file does not exist, the download
process will be bypassed. It will not affect the driver loading.

lan78xx: Read LED states from Device Tree
Add support for DT property "microchip,led-modes", a vector of zero
to four cells (u32s) in the range 0-15, each of which sets the mode
for one of the LEDs. Some possible values are:
These values are given symbolic constants in a dt-bindings header.
Also use the presence of the DT property to indicate that the
LEDs should be enabled - necessary in the event that no valid OTP
or EEPROM is available.

There is a standard mechanism for locating and using a MAC address from

applications without programmed EEPROM or OTP. At the same time,

lan78xx: Avoid spurious kevent 4 "error"
lan78xx_defer_event generates an error message whenever the work item
is already scheduled. lan78xx_open defers three events -
EVENT_STAT_UPDATE, EVENT_DEV_OPEN and EVENT_LINK_RESET. Being aware
of the likelihood (or certainty) of an error message, the DEV_OPEN
event is added to the set of pending events directly, relying on
the subsequent deferral of the EVENT_LINK_RESET call to schedule the
work. Take the same precaution with EVENT_STAT_UPDATE to avoid a
totally unnecessary error message.

irq-bcm2836: Prevent spurious interrupts, and trap them early
The old arch-specific IRQ macros included a dsb to ensure the
write to clear the mailbox interrupt completed before returning
from the interrupt. The BCM2836 irqchip driver needs the same
precaution to avoid spurious interrupts.
Spurious interrupts are still possible for other reasons,
though, so trap them early.

that set many values that are valid only for clearfog pro

This adds a sysfs 'clock_source' attribute which can be used to query
and set the clock source of the RTC, either 'internal' or 'external'.
Important note: Probing the pins of the 32kHz crystal with a scope will
not reliably tell you whether the (usually) more accurate external is
selected! On a 'Cubietech Cubietruck' board, the author saw a stable
32768Hz signal on the crystal, even though the internal oscillator was
selected and the clock wildly drifting.
Using adjtimex might help to figure out which oscillator is selected:
