drivers/pinctrl: Add the concept of an "init" state
For pinctrl the "default" state is applied to pins before the driver's
probe function is called. This is normally a sensible thing to do,
but in some cases can cause problems. That's because the pins will
change state before the driver is given a chance to program how those
pins should behave.
As an example you might have a regulator that is controlled by a PWM
(output high = high voltage, output low = low voltage). The firmware
might leave this pin as driven high. If we allow the driver core to
reconfigure this pin as a PWM pin before the PWM's probe function runs
then you might end up running at too low of a voltage while we probe.
Let's introudce a new "init" state. If this is defined we'll set
pinctrl to this state before probe and then "default" after probe
(unless the driver explicitly changed states already).
An alternative idea that was thought of was to use the pre-existing
"sleep" or "idle" states and add a boolean property that we should
start in that mode. This was not done because the "init" state is
needed for correctness and those other states are only present (and
only transitioned in to and out of) when (optional) power management
is enabled.

- Moved declarations to pinctrl/devinfo.h
- Fixed author/SoB

pinctrl: uniphier: set input-enable before pin-muxing
While IECTRL is disabled, input signals are pulled-down internally.
If pin-muxing is set up first, glitch signals (Low to High transition)
might be input to hardware blocks.
Bad case scenario:
[1] The hardware block is already running before pinctrl is handled.
(the reset is de-asserted by default or by a firmware, for example)
[2] The pin-muxing is set up. The input signals to hardware block
are pulled-down by the chip-internal biasing.
[3] The pins are input-enabled. The signals from the board reach the
hardware block.
Actually, one invalid character is input to the UART blocks for such
SoCs as PH1-LD4, PH1-sLD8, where UART devices start to run at the
power on reset.
To avoid such problems, pins should be input-enabled before muxing.

pinctrl: atlas7: support atlas7 step B changes
The the pin groups and pin functions have been changed
in atlas7 step B soc. We have to update the driver
to support step B chip.
Changes:
1. add 5 jtag pins to IOC_TOP:
"jtag_tdo", "jtag_tms","jtag_tck", "jtag_tdi", "jtag_trstn"
these 5 pins can be mutiplex with other functions, so we
have to conver these 5 pins in pinmux.
2. add pin groups for audio digmic, audio spdif, can transceiver
en, can transceiver stb, i2s0, i2s1 and jtag.
3. serval pins can be located to more PADs:
audio_uart0_urfs, audio_uart1_urfs, audio_uart2_urfs,
audio_uart2_urxd, audio_uart2_usclk, audio_uart2_utfs,
audio_uart2_utxd, can0_rxd, can0_txd, can1_rxd, can1_txd
jtag_ntrst, jtag_swdiotms, jtag_tck, jtag_tdi, jtag_tdo,
pw_cko0, pw_cko1, pw_i2s01, pw_pwm0, pw_pwm1, sd2_cdb,
sd2_wpb, uart2_cts, uart2_rts, uart2_rxd, uart2_txd,
uart3_cts, uart3_rts, uart3_rxd, uart3_txd, uart4_cts,
uart4_rts, usb0_drvvbus, usb1_drvvbus.
Because of Changes#3, some functions should have more than one
pin groups. So we have to split the original pin group to serval
pin groups.
For example:
audio_uart0 has 5 pins, on STEPA, each of these 5 pins only has
one related PAD. But on STEPB, audio_uart0_urfs has 4 related
PAD.
So we place the 4 pins with one PAD into a single pin group:
audio_uart0_basic_group.
and place urfs pin wtih different PADs to 4 different pin groups:
audio_uart0_urfs_group0, ..., audio_uart0_urfs_group3
A full audio_uart0 pin group can be:
pinctrl-0 = <&audio_uart0_basic_group &audio_uart0_urfs_group0>;
If audio_uart0 pin group encountered some confiction, we only have
to change the urfs group:
pinctrl-0 = <&audio_uart0_basic_group &audio_uart0_urfs_group2>;

fs-writeback: unplug before cond_resched in writeback_sb_inodes
Commit
505a666ee3fc ("writeback: plug writeback in wb_writeback() and
writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes,
which increases the merge rate when relatively contiguous small files
are written by the filesystem. It helps both on flash and spindles.
For an fs_mark workload creating 4K files in parallel across 8 drives,
this commit improves performance ~9% more by unplugging before calling
cond_resched(). cond_resched() doesn't trigger an implicit unplug, so
explicitly getting the IO down to the device before scheduling reduces
latencies for anyone waiting on clean pages.
It also cuts down on how often we use kblockd to unplug, which means
less work bouncing from one workqueue to another.
Many more details about how we got here:

mm: fix type cast in __pfn_to_phys()
The various definitions of __pfn_to_phys() have been consolidated to
use a generic macro in include/asm-generic/memory_model.h. This hit
mainline in the form of
012dcef3f058 "mm: move __phys_to_pfn and
__pfn_to_phys to asm/generic/memory_model.h". When the generic macro
was implemented the type cast to phys_addr_t was dropped which caused
boot regressions on ARM platforms with more than 4GB of memory and
LPAE enabled.
It was suggested to use PFN_PHYS() defined in include/linux/pfn.h
as provides the correct logic and avoids further duplication.
