a862dc3ea7 mfd: rc5t583: Set regmap config reg counts properly
Regmap config max_register field should contain number of
device last register, however num_reg_defaults_raw field
should be set to register count instead
(usually one register more than max_register).

rc5t583 driver had both of these fields set to the same value,
fix this by introducing separate defines for max register
number and total count of registers.

3f9be35bd9 mfd: rc5t583: Fix array subscript is above array bounds
I got below build warning while compiling this driver.
It's obviously RC5T583_MAX_INTERRUPT_MASK_REGS is 9 but irq_en_add
array only has 8 elements.

  CC      drivers/mfd/rc5t583-irq.o
drivers/mfd/rc5t583-irq.c: In function 'rc5t583_irq_sync_unlock':
drivers/mfd/rc5t583-irq.c:227: warning: array subscript is above array bounds
drivers/mfd/rc5t583-irq.c: In function 'rc5t583_irq_init':
drivers/mfd/rc5t583-irq.c:349: warning: array subscript is above array bounds

Since the number of interrupt enable registers is 8, this patch adds
define for RC5T583_MAX_INTERRUPT_EN_REGS to fix this bug.

90829c089e rtc: rc5t583: add ricoh rc5t583 RTC driver
Add an RTC driver for the RTC device on Ricoh MFD Rc5t583.  Ricoh RTC has
3 types of alarms.  The current patch adds support for the Y-Alarm of
RC5t583 RTC.

b1bf7d4d1b GPIO driver changes for v3.5 merge window
Lots of gpio changes, both to core code and drivers.  Changes do touch
 architecture code to remove the need for separate arm/gpio.h includes
 in most architectures.  Some new drivers are added, and a number of
 gpio drivers are converted to use irq_domains for gpio inputs used as
 interrupts.  Device tree support has been amended to allow multiple
 gpio_chips to use the same device tree node.  Remaining changes are
 primarily bug fixes.

82ea267f7d mfd: Fix modular builds of rc5t583 regulator support
The combination of commit 1b1247dd75

    "mfd: Add support for RICOH PMIC RC5T583"

and commit 6ffc327021

    "regulator: Add support for RICOH PMIC RC5T583 regulator"

are causing the i386 allmodconfig builds to fail with this:

  ERROR: "rc5t583_update" [drivers/regulator/rc5t583-regulator.ko] undefined!
  ERROR: "rc5t583_set_bits" [drivers/regulator/rc5t583-regulator.ko] undefined!

and this:

  ERROR: "rc5t583_ext_power_req_config" [drivers/regulator/rc5t583-regulator.ko] undefined!

For the 1st four, make the simple ops static inline, instead of
polluting the namespace with trivial exports.  For the last one,
add an EXPORT_SYMBOL.

6ffc327021 regulator: Add support for RICOH PMIC RC5T583 regulator
The RC5T583 PMIC from RICOH consists of 4 DCDC and 10
LDOs. This driver supports the control of different
regulator output through regulator interface.
This driver depends on MFD driver of RC5T583 and uses
mfd rc5t583 apis to communicate to device for accessing
different device's registers.
