HS400 timing values are added for SMDK5420, exynos5420-peach-pit
and exynos5800-peach-pi boards. This also adds RCLK GPIO line,

The kernel can use as the default console a serial port if is defined

This allows a board to be booted without the need of having a console
parameter in the kernel command line.

Currently the Spring DTS has bootargs in the /chosen node and this is
kept since users that don't have a serial console on this board might
be using it to have the boot log shown in the display. This will have
more precedence than the stdout-path but it's fine since is only used

Peach Pit and Pi boards have a WiFi module that is always powered
but needs toggling an enable pin and ungating a 32kHz reference
clock as part of their power sequencing.

Add a dev node for the SDIO slot and a MMC power sequence provider.
Signed-off-by: NJavier Martinez Canillas <javier.martinez@collabora.co.uk>
Signed-off-by: NKukjin Kim <kgene@kernel.org>

The Exynos5420 SoC has 3 sets of 8 pads used as data lines for the 3
MMC/SD/SDIO slots. These needs to be muxed as SD_n_DATA instead of a
GPIO or external interrupt to allow the MMC controller to communicate
with the attached cards or SDIO devices.

Which data lines needs to be muxed as SD_n_DATA depends on the bus
width used for data transfer:

* bus-width = <1> needs SD_n_DATA[0]
* bus-width = <4> needs SD_n_DATA[0-3]
* bus-width = <8> needs SD_n_DATA[0-7]

The Exynos5250-pinctrl.dtsi file that defines the groups of pins has
SD_n_DATA[0] muxed for both sdn_bus1 and sdn_bus4 so just one of them
needs to be included in the device node's pinctrl property.

But Exynos5420-pinctrl has a different definition and only includes
SD_n_DATA[1-3] for sdn_bus4. So for a bus-width = <4>, both sdn_bus1
and sdn_bus4 have to be in the dev pinctrl to mux all the needed pads.

It seems all Exynos5420 boards had just cargo cult the pinctrl lines
assuming that sdn_bus4 also included SD_n_DATA[0] and it only works
because the bootloader muxes the pads correctly. But that is not the
case for the devices not used by the bootloader such as WiFi modules.

Add sdn_bus1 too in the nodes pinctrl to not rely on the bootloader.

The Snow board has a MMC/SDIO wifi chip that is always powered but it
needs a power sequence involving a reset (active low) and an enable
(active high) pins. Both pins are marked as active low since the MMC
simple power sequence driver asserts the pins prior to the card power
up procedure and de-asserts the pins after the card has been powered.

So the reset line will be left de-asserted and the enable pin will be
left asserted.

The chip also needs an external 32kHz reference clock to be operational
that is by the MAX77686 PMIC clock.

Add a simple MMC power sequence provider for the wifi MMC/SDIO slot.

.. after extensive statistical analysis of my G+ polling, I've come to
the inescapable conclusion that internet polls are bad.

Big surprise.

But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
margin, in a poll that people weren't even supposed to participate in.
Who can argue with solid numbers like that? 5,796 votes from people who
can't even follow the most basic directions?

In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
but with a total of 29,110 votes right now.

Now, arguably, that vote spread is only about 3,200 votes, which is less
than the almost six thousand votes that the "please ignore" poll got, so
it could be considered noise.

But hey, I asked, so I'll honor the votes.

I've noticed significant locking contention in memory reclaimer around
sb_lock inside grab_super_passive(). Grab_super_passive() is called from
two places: in icache/dcache shrinkers (function super_cache_scan) and
from writeback (function __writeback_inodes_wb). Both are required for
progress in memory allocator.

Grab_super_passive() acquires sb_lock to increment sb->s_count and check
sb->s_instances. It seems sb->s_umount locked for read is enough here:
super-block deactivation always runs under sb->s_umount locked for write.
Protecting super-block itself isn't a problem: in super_cache_scan() sb
is protected by shrinker_rwsem: it cannot be freed if its slab shrinkers
are still active. Inside writeback super-block comes from inode from bdi
writeback list under wb->list_lock.

This patch removes locking sb_lock and checks s_instances under s_umount:
generic_shutdown_super() unlinks it under sb->s_umount locked for write.
New variant is called trylock_super() and since it only locks semaphore,
callers must call up_read(&sb->s_umount) instead of drop_super(sb) when
they're done.

Convert the following where appropriate:

 (1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry).

 (2) S_ISREG(dentry->d_inode) to d_is_reg(dentry).

 (3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry).  This is actually more
     complicated than it appears as some calls should be converted to
     d_can_lookup() instead.  The difference is whether the directory in
     question is a real dir with a ->lookup op or whether it's a fake dir with
     a ->d_automount op.

In some circumstances, we can subsume checks for dentry->d_inode not being
NULL into this, provided we the code isn't in a filesystem that expects
d_inode to be NULL if the dirent really *is* negative (ie. if we're going to
use d_inode() rather than d_backing_inode() to get the inode pointer).

Note that the dentry type field may be set to something other than
DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS
manages the fall-through from a negative dentry to a lower layer.  In such a
case, the dentry type of the negative union dentry is set to the same as the
type of the lower dentry.

However, if you know d_inode is not NULL at the call site, then you can use
the d_is_xxx() functions even in a filesystem.

There is one further complication: a 0,0 chardev dentry may be labelled
DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE.  Strictly, this was
intended for special directory entry types that don't have attached inodes.

The following perl+coccinelle script was used:

use strict;

Introduce some function for getting the inode (and also the dentry) in an

The problem is that we have places where we need *both* the union dentry and
the lower source or workspace inode or dentry available, but we can only have
a handle on one of them.  Therefore we need to derive the handle to the other
from that.

The idea is to introduce an extra field in struct dentry that allows the union
