Pull MFD (multi-function device) updates from Samuel Ortiz:
"For the 3.12 merge window we have one new driver for the DA9063 PMIC
from Dialog Semiconductor.Besides that driver we also have:
- Device tree support for the s2mps11 driver
- More devm_* conversion for the pm8921, max89xx, menelaus, tps65010,
wl1273 and pcf50633-adc drivers.- A conversion to threaded IRQ and IRQ domain for the twl6030 driver.
- A fairly big update for the rtsx driver: Better power saving
support, better vendor settings handling, and a few fixes.- Support for a couple more boards (COMe-bHL6 and COMe-cTH6) for the
Kontron driver.- A conversion to the dev_get_platdata() API for all MFD drivers.
- A removal of non-DT (legacy) support for the twl6040 driver.
- A few fixes and additions (Mic detect level) to the wm5110 register
tables.- Regmap support for the davinci_voicecodec driver.
- The usual bunch of minor cleanups and janitorial fixes"

Error handling is on-its-head in this function. After invoking a function we
should examine the return code and return the error value if there was one.
Instead, this function checks for success and goes onto provide functionality
if success was received. Not so bad in a simple function like this, but in
a more complex one this could end up drowning in curly brackets.Signed-off-by: Lee Jones

The AB8500 debugfs driver allocates memory to contain the name of a new sysfs
entry, but fails to apply the proper post-allocation checks. If the device
were to run out of memory, the allocation would return NULL. Without the
correct checks the driver will continue to populate address NULL with the
specified device name which would obviously cause a pointer dereference Oops.Signed-off-by: Lee Jones

The default phase can meet most cards' requirement, but it is not the
optimal one. In some extreme situation, the rx phase point produced by
the following tuning process will drift quite a distance.
Before tuning UHS card, this patch will set a more proper initial tx
phase point, which is calculated from statistic data, and can achieve
a much better tx signal quality.Signed-off-by: Wei WANG

Some actions to clear power state should be handled in .shutdown
callback in rtsx_pci_driver. This patch adopts the following measures to

Acked-by: Graeme Gregory
Signed-off-by: Samuel Ortiz -
Since the TWL6030 PMIC is used with OMAP4 SoCs only and OMAP4 legacy
boot is dropped there are no needs to allocate the range of IRQ
descriptors during system boot to support TWL6030 IRQs.Hence, convert it to use linear irq_domain and move IRQ configuration in
.map()/.unmap() callbacks of irq_domain. So, IRQ mapping and descriptors
allocation will be performed dynamically basing on DT configuration.The error message will be reported in case if unmapped IRQ is received by
TWL6030 (virq==0).Signed-off-by: Grygorii Strashko

1) Removed request_irq() and replaced it with request_threaded_irq().
2) Removed generic_handle_irq() and replaced it with
handle_nested_irq().
Handling of these interrupts is nested, as we are handling an
interrupt (for e.g rtc, mmc1) when we are still servicing TWL irq.3) Removed I2C read-retry logic for the case when twl_i2c_read() is
failed inside IRQ handler - there is no sense to do that, so just report
an error and return.4) Each nested IRQ is configured with corresponding parent_irq,
which need to be retriggered in case if nested IRQ is marked
as IRQS_PENDING.Signed-off-by: Naga Venkata Srikanth V
