HFS+ doesn't really implement hard links - instead, hardlinks are indicated
by a magic file type which refers to an indirect node in a hidden
directory. The spec indicates that stat() should return the inode number
of the indirect node, but it turns out that this doesn't satisfy the
firmware when it's looking for a bootloader - it wants the catalog ID of
the hardlink file instead. Fix up this case.

If the GPIOs used by the MMCI driver are not registered yet when the driver is
probe()d, they can't be used. This happens if the mmci driver is probed before
the respective GPIO controller (e.g. on the LPC32xx EA3250 board, the PCA9532
GPIO controller would be initialized via DT after mmci). Therefore, we defer
mmci in this case.

Devices with register paging or indirectly accessed registers can configure
register mapping to map those on virtual address range. During access to
virtually mapped register range, indirect addressing is processed
automatically, in following steps:
1. selector for page or indirect register is updated (when needed);
2. register in data window is accessed.
Configuration should provide minimum and maximum register for virtual range,
details of selector field for page selection, minimum and maximum register of
data window for indirect access.
Virtual range registers are managed by cache as well as direct access
registers. In order to make indirect access more efficient, selector register
should be declared as non-volatile, if possible.
struct regmap_config is extended with the following:
struct regmap_range_cfg *ranges;
unsigned int n_ranges;
[Also reordered debugfs init to later on since the cleanup code was
conflicting with the new cleanup code for ranges anyway -- broonie]

For some hardwares ramp_delay for BUCKs is a configurable parameter which can
be configured through DT or board file.This patch adds ramp_delay to regulator
constraints and allow user to configure it for regulators which supports this
feature, through DT or board file. It will provide two ways of setting the
ramp_delay for a regulator:
First, by setting it as constraints in board file(for configurable
regulators) and set_machine_constraints() will take care of setting it on
hardware by calling(the provided) .set_ramp_delay() operation(callback).
Second, by setting it as data in regulator_desc(as fixed/default
ramp_delay rate) for a regulator in driver.
regulator_set_voltage_time_sel() will give preference to
constraints->ramp_delay while reading ramp_delay rate for regulator. Similarly
users should also take care accordingly while refering ramp_delay rate(in case
of implementing their private .set_voltage_time_sel() callbacks for different
regulators).

The min_uV and max_uV are not really used in the code and misleading because
the min_uV and max_uV settings does not match the value in the voltage table.
For example, we have
static const unsigned int ldo_vaux3_voltages[] = {
1200000,
1500000,
1800000,
2100000,
2500000,
2750000,
2790000,
2910000,
};
With below min_uV/max_uV settings for AB8500_LDO_AUX3.
.min_uV = 1100000,
.max_uV = 3300000,
The min_uV/max_uV for AB8500_LDO_AUX3 seems copy-paste from AB8500_LDO_AUX2

The LDO_CTRL registers are used to set the output voltage of LDO1 and LDO2.

The voltage being set should be passed to the call in handler
requesting the callback. Currently this is not done.
The calling handler cannot call regulator_get_voltage() to get the
information since the mutex is held by the regulator and
deadlock occurs.
Without this change the receiver of the call in cannot know what
action to take. This is used, for example, to set PAD voltages
when doing SD vccq voltage changes.
