The pinmux configuration in device tree was different from manual
muxing in <u-boot>/board/freescale/mx53loco/mx53loco.c
All pins were configured as NO_PAD_CTL(1 << 31), which was fine as the
bootloader already did the correct pinmuxing for us.
But recently u-boot is migrating to reuse device tree files from the
kernel tree, so it seems to be better to have the correct pinmuxing in
our files, too.

On i.MX6QP the FEC interrupts are wired to the GPC, just like all other
device interrupts. This allows to FEC to wake the CPU from WFI, but for
this to work the kernel needs to know about the new IRQ routing.

The regulation bound of this regulator are 2.1V to 2.875V, the
wrong DT values cause the driver to miscalculate the effective
voltage.
This isn't really an issue right now, as nobody actively changes
the regulator voltage, but better fix it now.

The i.MX7 has two iomux controllers. the iomuxc and the iomuxc_lpsr.
In a board dts we have to make sure that both controllers are supplied
with the correct pins. It's way too easy to do this wrong since only
a look into the reference manual can reveal which pins belong to which
controller. To make this clearer add "LPSR" to the pin names which
belong to the LPSR controller.

This function is a minor misnomer: it is talking about 'marking' regions
as nosave - while the hibernation API is called register_nosave_region()
and the e820_mark_nosave_regions() is a wrapper around that functionality.
So name it to be in line with the API it is derived from.
( Rename e820_mark_nvs_memory() to e820__register_nvs_regions(), for similar
reasons. )

The __e820__update_table() function has various weirdly named variables,
such as 'pbios', 'biosmap' and 'pnr_map' which are pretty confusing
and actively misleading at times.
This weird naming found its way into other functions as well, such as
__append_e820_table() and append_e820_table().
Standardize the naming to make it all much easier to read:
biosmap -> entries
pbios -> entry
nr_map -> nr_entries
pnr_map -> nr_entries
...
Also clean up the types used: entry indices routinely mixed u32 and int,
standardize on u32 thoughout.
Update the comments as well, while at it.

The e820__update_table() parameters are pretty complex:
arch/x86/include/asm/e820/api.h:extern int e820__update_table(struct e820_entry *biosmap, int max_nr_map, u32 *pnr_map);
But 90% of the usage is trivial:
arch/x86/kernel/e820.c: if (e820__update_table(e820_table->entries, ARRAY_SIZE(e820_table->entries), &e820_table->nr_entries))
arch/x86/kernel/e820.c: e820__update_table(e820_table->entries, ARRAY_SIZE(e820_table->entries), &e820_table->nr_entries);
arch/x86/kernel/e820.c: e820__update_table(e820_table->entries, ARRAY_SIZE(e820_table->entries), &e820_table->nr_entries);
arch/x86/kernel/e820.c: if (e820__update_table(e820_table->entries, ARRAY_SIZE(e820_table->entries), &e820_table->nr_entries) < 0)
arch/x86/kernel/e820.c: e820__update_table(boot_params.e820_table, ARRAY_SIZE(boot_params.e820_table), &new_nr);
arch/x86/kernel/early-quirks.c: e820__update_table(e820_table->entries, ARRAY_SIZE(e820_table->entries), &e820_table->nr_entries);
arch/x86/kernel/setup.c: e820__update_table(e820_table->entries, ARRAY_SIZE(e820_table->entries), &e820_table->nr_entries);

arch/x86/platform/efi/efi.c: e820__update_table(e820_table->entries, ARRAY_SIZE(e820_table->entries), &e820_table->nr_entries);

arch/x86/xen/setup.c: e820__update_table(e820_table->entries, ARRAY_SIZE(e820_table->entries), &e820_table->nr_entries);
arch/x86/xen/setup.c: e820__update_table(xen_e820_table.entries, ARRAY_SIZE(xen_e820_table.entries),
as it only uses an exiting struct e820_table's entries array, its size and
its current number of entries as input and output arguments.
Only one use is non-trivial:
arch/x86/kernel/e820.c: e820__update_table(boot_params.e820_table, ARRAY_SIZE(boot_params.e820_table), &new_nr);
... which call updates the E820 table in the zeropage in-situ, and the layout there does not
match that of 'struct e820_table' (in particular nr_entries is at a different offset,
hardcoded by the boot protocol).
Simplify all this by introducing a low level __e820__update_table() API that
the zeropage update call can use, and simplifying the main e820__update_table()
call signature down to:
int e820__update_table(struct e820_table *table);
This visibly simplifies all the call sites:
arch/x86/include/asm/e820/api.h:extern int e820__update_table(struct e820_table *table);
arch/x86/include/asm/e820/types.h: * call to e820__update_table() to remove duplicates. The allowance
arch/x86/kernel/e820.c: * The return value from e820__update_table() is zero if it
arch/x86/kernel/e820.c:int __init e820__update_table(struct e820_table *table)
arch/x86/kernel/e820.c: if (e820__update_table(e820_table))
arch/x86/kernel/e820.c: e820__update_table(e820_table_firmware);

There's various sizeof() uses in e820.c - standardize on the shortest
and least error prone one, along the pattern of:
- memset(entry, 0, sizeof(struct e820_entry));
+ memset(entry, 0, sizeof(*entry));
... because with this pattern in most cases it's immediately clear that
we have used the right type - and the pattern is robust against changing
the type as well.

We've got a number of defines related to the E820 table and its size:
E820MAP
E820NR
E820_X_MAX
E820MAX
The first two denote byte offsets into the zeropage (struct boot_params),
and can are not used in the kernel and can be removed.
The E820_*_MAX values have an inconsistent structure and it's unclear in any
case what they mean. 'X' presuably goes for extended - but it's not very
expressive altogether.
Change these over to:
E820_MAX_ENTRIES_ZEROPAGE
E820_MAX_ENTRIES
... which are self-explanatory names.

So there's a number of constants that start with "E820" but which
are not types - these create a confusing mixture when seen together
with 'enum e820_type' values:
E820MAP
E820NR
E820_X_MAX
E820MAX
To better differentiate the 'enum e820_type' values prefix them
with E820_TYPE_.

If an i2c access through i2c-cros-ec-tunnel returns an error, the following
log message is seen on the console.
cros-ec-i2c-tunnel ff200000.spi:ec@0:i2c-tunnel:
Error parsing EC i2c message -121
This can happen a lot if, for example, the i2c-detect command is executed.
Since it is perfectly normal for an i2c controller to report an error,
drop the message. Also, report -ENXIO instead of -EREMOTEIO if the access
error is due to NAK from the device, and return -EIO instead of -EREMOTEIO
for other errors, as suggested in Documentation/i2c/fault-codes.

In swab.h the "#if BITS_PER_LONG > 32" breaks compiling userspace programs if
BITS_PER_LONG is #defined by userspace with the sizeof() compiler builtin.
Solve this problem by using __BITS_PER_LONG instead. Since we now
#include asm/bitsperlong.h avoid further potential userspace pollution
by moving the #define of SHIFT_PER_LONG to bitops.h which is not
exported to userspace.
This patch unbreaks compiling qemu on hppa/parisc.

This is the IIO driver for devantech srf08 ultrasonic ranger which can be
used to measure the distances to an object.
The sensor supports I2C with some registers.
Supported Features include:
- read the distance in ranging mode in centimeters
- output of the driver is directly the read value
- together with the scale the driver delivers the distance in meters
- only the first echo of the nearest object is delivered
- set sensitivity as analog value in the range of 0-31 means setting
gain register on device
- set range registers; userspace enters max. range in millimeters in
43 mm steps
Features not supported by this driver:
- ranging mode in inches or in microseconds
- ANN mode
- change I2C address through this driver
- light sensor
The driver was added in the directory "proximity" of the iio subsystem and
the menu in den config is now called "Proximity and distance sensors"
