[ Upstream commit 2c949ce38f4e81d7487f165fa3b8f77d74a2a6c4 ]
The PCIe programming sequence in TRM suggests CLKSTCTRL of PCIe should be
set to SW_WKUP. There are no issues when CLKSTCTRL is set to HW_AUTO in RC
mode. However in EP mode, the host system is not able to access the
MEMSPACE and setting the CLKSTCTRL to SW_WKUP fixes it.

[ Upstream commit 863204cfdae98626a92535ac928ad79f4d6b74ff ]
In configurations without CONFIG_OMAP3 but with secure RAM support,
we now run into a link failure:
arch/arm/mach-omap2/omap-secure.o: In function `omap3_save_secure_ram':
omap-secure.c:(.text+0x130): undefined reference to `save_secure_ram_context'
The omap3_save_secure_ram() function is only called from the OMAP34xx
power management code, so we can simply hide that function in the
appropriate #ifdef.

[ Upstream commit b6d6af7226465b6d11eac09d0be2ab78a4a9eb62 ]
Referring TRM Am335X series:
http://www.ti.com/lit/ug/spruh73p/spruh73p.pdf
The LastPowerStateEntered bitfield is present only for PM_CEFUSE
domain. This is not present in any of the other power domains. Hence
remove the generic am33xx_pwrdm_read_prev_pwrst hook which wrongly
reads the reserved bit fields for all the other power domains.
Reading the reserved bits leads to wrongly interpreting the low
power transitions for various power domains that do not have the
LastPowerStateEntered field. The pm debug counters values are wrong
currently as we are incrementing them based on the reserved bits.

[ Upstream commit d09220a887f70368afa79e850c95e74890c0a32d ]
With the CMA changes from Joonsoo Kim <iamjoonsoo.kim@lge.com>, it
was noticed that n900 stopped booting. After investigating it turned
out that n900 save_secure_ram_context does some whacky virtual to
physical address translation for the SRAM data address.
As we now only have minimal parts of omap3 idle code copied to SRAM,
running save_secure_ram_context() in SRAM is not needed. It only gets
called on PM init. And it seems there's no need to ever call this from
SRAM idle code.
So let's just keep save_secure_ram_context() in DDR, and pass it the
physical address of the parameters. We can do everything else in
omap-secure.c like we already do for other secure code.
And since we don't have any documentation, I still have no clue what
the values for 0, 1 and 1 for the parameters might be. If somebody has
figured it out, please do send a patch to add some comments.

[ Upstream commit 98f42221501353067251fbf11e732707dbb68ce3 ]
Based on CPU type choose generic omap3 or omap3430 specific cpuidle
parameters. Parameters for omap3430 were measured on Nokia N900 device and
added by commit 5a1b1d3a9efa ("OMAP3: RX-51: Pass cpu idle parameters")
which were later removed by commit 231900afba52 ("ARM: OMAP3: cpuidle -
remove rx51 cpuidle parameters table") due to huge code complexity.
This patch brings cpuidle parameters for omap3430 devices again, but uses
simple condition based on CPU type.

[ Upstream commit 3ca4a238106dedc285193ee47f494a6584b6fd2f ]
Commit 127500ccb766f ("ARM: OMAP2+: Only write the sysconfig on idle
when necessary") talks about verification of sysconfig cache value before
updating it, only during idle path. But the patch is adding the
verification in the enable path. So, adding the check in a proper place
as per the commit description.
Not keeping this check during enable path as there is a chance of losing
context and it is safe to do on idle as the context of the register will
never be lost while the device is active.

Some module needs more than one functional clock in order to be accessible,
like the McASPs found in DRA7xx family.
This flag will indicate that the opt_clks need to be handled at the same

are enabled before we try to access the module's address space.

commit 63059a272398ef5dc1bd7065a036e8b6e82d1af7 upstream.
The conversion of the wakeupgen irqchip to hierarchical irq domains
failed to provide a mechanism to properly set the trigger type of an
interrupt.
The wakeupgen irq chip itself has no mechanism and therefor no
irq_set_type() callback. The code before the conversion relayed the
trigger configuration directly to the underlying GIC.
Restore the correct behaviour by setting the wakeupgen irq_set_type
callback to irq_chip_set_type_parent(). This propagates the
set_trigger() call to the underlying GIC irqchip.

commit 9a258afa928b45e6dd2efcac46ccf7eea705d35a upstream.
For hwmods without sysc, _init_mpu_rt_base(oh) won't be called and so
_find_mpu_rt_port(oh) will return NULL thus preventing ready state check
on those modules after the module is enabled.
This can potentially cause a bus access error if the module is accessed
before the module is ready.
Fix this by unconditionally calling _init_mpu_rt_base() during hwmod
_init(). Do ioremap only if we need SYSC access.
Eventhough _wait_target_ready() check doesn't really need MPU RT port but
just the PRCM registers, we still mandate that the hwmod must have an
MPU RT port if ready state check needs to be done. Else it would mean that
the module is not accessible by MPU so there is no point in waiting
for target to be ready.
e.g. this fixes the below DCAN bus access error on AM437x-gp-evm.

The power management related assembly on omaps needs to interact with
ARM mode bootrom code, so we need to keep most of the related assembly
in ARM mode.
Turns out this error is because of missing ENDPROC for assembly code
as suggested by Stephen Boyd <sboyd@codeaurora.org>. Let's fix the
problem by adding ENDPROC in two places to sleep34xx.S.
Let's also remove the now duplicate custom code for mode switching.
This has been unnecessary since commit 6ebbf2ce437b ("ARM: convert
all "mov.* pc, reg" to "bx reg" for ARMv6+").
And let's also remove the comments about local variables, they are
now just confusing after the ENDPROC.
The reason why ENDPROC makes a difference is it sets .type and then
the compiler knows what to do with the thumb bit as explained at:

ARM: OMAP2+: first set of hwmod fixes for v4.1-rc
Fix a few AM43xx problems: add the VPFE hwmod data, which removes some
warnings; and fix the IP block hardreset implementation.
Basic build, boot, and PM test results are here:
http://www.pwsan.com/omap/testlogs/omap-hwmod-a-for-v4.1-rc/20150508130543/
Note that I do not have an AM43xx board in the testbed, and thus
cannot test on that platform.

With recent changes to use determine_rate, the comparison of two
clocks won't work without clk_is_match that does __clk_get_hw
on the clocks first.
As we've been unconditionally already calling clk_set_parent
already because of the bogus comparison, let's just remove the
check as suggested by Stephen Boyd <sboyd@codeaurora.org>.

The reset code functionality is mostly a copy paste between OMAP4+ and
AM33xx+. Re-use the omap4 code where possible, and just keep the special
implementation for de-asserting the hardreset lines for AM33xx, as
AM33xx+ devices have slightly different register layouts compared to
OMAP4+. This patch also fixes the hardreset issues faced on AM43xx.

AM43xx has slightly different reset register layout compared to OMAP4+,
with varying status bit shifts and status register offsets. Current
code assumes static offsets and identical status / reset control bit
shifts, which is wrong. This patch adds PRM core support for passing
the actual implementations from hwmod code. AM43xx mappings will be fixed
in subsequent patch.

If we use a combination of VMODE and I2C4 for retention modes,
eventually the off idle power consumption will creep up by about
23mW, even during off mode with I2C4 always staying enabled.
Turns out this is because of erratum i531 "Extra Power Consumed
When Repeated Start Operation Mode Is Enabled on I2C Interface
Dedicated for Smart Reflex (I2C4)" as pointed out by Nishanth
Menon <nm@ti.com>.
Let's fix the issue by adding i2c_cfg_clear_mask for the bits
to clear when initializing the I2C4 adapter so we can clear
SREN bit that drives the I2C4 lines low otherwise when there
is no traffic.

Lindgren:
Urgent pull request for v4.1 to booting for custom kernel
.config files that do not have MFD_SYSCON set.
Omaps now have a dependency to MFD_SYSCON for system control
module generic register area and some clocks with the changes
done in omap-for-v4.1/prcm-dts branch.
This can be pulled on top of omap-for-v4.1/prcm-dts, or into
fixes for v4.1.
We already do have a slight MFD_SYSCON dependency for
REGULATOR_PBIAS for dual voltage MMC cards on the first MMC
bus for many devices, so from that point of view this can
also be merged separately from omap-for-v4.1/prcm-dts.

There also is some consolidation in the unified device properties API
area allowing us to use that inferface for accessing data coming from
platform initialization code in addition to firmware-provided data.
We have some new device/CPU IDs in a few drivers, support for new
chips and a new cpufreq driver too.
Specifics:
- Generic PM domains support update including new PM domain callbacks
to handle device initialization better (Russell King, Rafael J
Wysocki, Kevin Hilman)
- Unified device properties API update including a new mechanism for
accessing data provided by platform initialization code (Rafael J
Wysocki, Adrian Hunter)
- ARM cpuidle update including ARM32/ARM64 handling consolidation
(Daniel Lezcano)
- intel_idle update including support for the Silvermont Core in the
Baytrail SOC and for the Airmont Core in the Cherrytrail and
Braswell SOCs (Len Brown, Mathias Krause)
- New cpufreq driver for Hisilicon ACPU (Leo Yan)
- intel_pstate update including support for the Knights Landing chip
(Dasaratharaman Chandramouli, Kristen Carlson Accardi)

- powernv cpufreq driver update (Shilpasri G Bhat)
- devfreq update including Tegra support changes (Tomeu Vizoso,
MyungJoo Ham, Chanwoo Choi)
- powercap RAPL (Running-Average Power Limit) driver update including
support for Intel Broadwell server chips (Jacob Pan, Mathias Krause)
- ACPI device enumeration update related to the handling of the
special PRP0001 device ID allowing DT-style 'compatible' property
to be used for ACPI device identification (Rafael J Wysocki)
- ACPI EC driver update including limited _DEP support (Lan Tianyu,
Lv Zheng)
- ACPI backlight driver update including a new mechanism to allow
native backlight handling to be forced on non-Windows 8 systems and
a new quirk for Lenovo Ideapad Z570 (Aaron Lu, Hans de Goede)
- New Windows Vista compatibility quirk for Sony VGN-SR19XN (Chen Yu)
- Assorted ACPI fixes and cleanups (Aaron Lu, Martin Kepplinger,
Masanari Iida, Mika Westerberg, Nan Li, Rafael J Wysocki)
- Fixes related to suspend-to-idle for the iTCO watchdog driver and
the ACPI core system suspend/resume code (Rafael J Wysocki, Chen Yu)
- PM tracing support for the suspend phase of system suspend/resume
transitions (Zhonghui Fu)

The omap3isp MMIO register block is contiguous in the MMIO register space
apart from the fact that the ISP IOMMU register block is in the middle of
the area. Ioremap it at two occasions, and keep the rest of the layout of
the register space internal to the omap3isp driver.

The syscon register isn't part of the ISP, use it through the syscom driver
regmap instead. The syscom block is considered to be from 343x on ISP
revision 2.0 whereas 15.0 is assumed to have 3630 syscon.

Make omap3isp configuration data structures more suitable for consumption by
the DT by separating the I2C bus information of all the sub-devices in a
group and the ISP bus information from each other. The ISP bus information
is made a pointer instead of being directly embedded in the struct.
In the case of the DT only the sensor specific information on the ISP bus
configuration is retained. The structs are renamed to reflect that.
After this change the structs needed to describe device configuration can be
allocated and accessed separately without those needed only in the case of
platform data. The platform data related structs can be later removed once
the support for platform data can be removed.
