Create basic voltagedomains for OMAP2 and associate OMAP2 powerdomains
with the newly created voltage domains.While here, update copyright on powerdomain data to 2011.

Each powerdomain is associated with a voltage domain. Add an entry to
struct powerdomain where the enclosing voltagedomain can be
referenced.Modeled after similar relationship between clockdomains and powerdomains.

Add a 'bool scalable' flag to the struct powerdomain and set it for

Add wakeup voltage domain so that the wakeup powerdomain can have an
associated powerdomain. Note that the scalable flat is not set for
the this voltagedomain, so it will not be fully initialized like
scalable voltage domains.Signed-off-by: Kevin Hilman

This voltage domain (a.k.a. VDD1) contains both the MPU and the IVA, so

Start cleaning up the voltage layer to have a voltage domain layer
that resembles the structure of the existing clock and power domain
layers. To that end:- move the 'struct voltagedomain' out of 'struct omap_vdd_info' to
become the primary data structure.- convert any functions taking a pointer to struct omap_vdd_info into
functions taking a struct voltagedomain pointer.- convert the register & initialize of voltage domains to look like
that of powerdomains- convert omap_voltage_domain_lookup() to voltdm_lookup(), modeled
after the current powerdomain and clockdomain lookup functions.- omap_voltage_late_init(): only configure VDD info when
the vdd_info struct is non-NULLSigned-off-by: Kevin Hilman

The prm_irqst_reg is not part of the VP. Move it up into the common

Eliminate need for global variables for the various PRM module offsets by
making them part of the VP/VC common structuresEventually, these will likely be moved again, or more likely removed
when VP/VC code is isolated, but for now just getting rid of them as
global variabes so that the voltage domain initialization can be
cleaned up.Signed-off-by: Kevin Hilman

The voltage domain pointer currently in struct omap_hwmod is not used

At Tony's request, remove the omap_chip bitmasks from the powerdomain
definitions. Instead, initialize powerdomains based on one or more
lists that are applicable to a particular SoC family, variant, and
silicon revision.Gražvydas Ignotas found and reported a bug in a
related patch that also applied to this patch - thanks Gražvydas.Signed-off-by: Paul Walmsley

In preparation for OMAP_CHIP() removal, split pwrdm_init() into three
functions. This allows some of them to be called multiple times: for
example, pwrdm_register_pwrdms() can be called once to register
powerdomains that are common to a group of SoCs, and once to register
powerdomains that are specific to a single SoC.The appropriate order to call these functions - which is enforced
by the code - is:1. pwrdm_register_platform_funcs()
2. pwrdm_register_pwrdms() (can be called multiple times)
3. pwrdm_complete_init()Convert the OMAP2, 3, and 4 powerdomain init code to use these new
functions.While here, improve documentation, and increase CodingStyle
conformance by shortening some local variable names.Signed-off-by: Paul Walmsley

The OMAP3505/AM3505 appears to be based on the same silicon as the
OMAP3517/AM3517, with some features disabled via eFuse bits. Follow
the same practice as OMAP3430 and identify these devices internally as
part of the OMAP3517/AM3517 family.The OMAP3503/3515/3525/3530 chips appear to be based on the same silicon
as the OMAP3430, with some features disabled via eFuse bits. Identify
these devices internally as part of the OMAP3430 family.Remove the old OMAP35XX_CLASS, which actually covered two very different
chip families. The OMAP3503/3515/3525/3530 chips will now be covered by
OMAP343X_CLASS, since the silicon appears to be identical. For the
OMAP3517/AM3517 family, create a new class, OMAP3517_CLASS.Thanks to Tony Lindgren for some help with the second
revision of this patch.Signed-off-by: Paul Walmsley

This bug causes the IECSR register clear failure. In this case, the RETE
(retry error threshold exceeded) interrupt will be generated and cannot be
cleared. So the related ISR may be called persistently.The RETE bit in IECSR is cleared by writing a 1 to it.

The previous rtc-s3c had two issues related with its IRQ.
1. Users cannot open rtc multiple times because an open operation
calls request_irq on the same IRQ. (e.g., two user processes wants to
open and read RTC time from rtc-s3c at the same time)2. If alarm is set and no one has the rtc opened with filesystem
(either the alarm is set by kernel/boot-loader or user set an alarm and
closed rtc dev file), the pending bit is not cleared and no further
interrupt is invoked. When the alarm is used by the system itself such
as a resume from suspend-to-RAM or other Low-power modes/idle, this is
a critical issue.This patch mitigates these issues by calling request_irq at probe and
free_irq at remove.Signed-off-by: MyungJoo Ham
