Suman Anna e5ed5b6027 ARM: OMAP2+: Fix socbus family info for AM33xx devices
The family information in the soc-bus data is currently
not classified properly for AM33xx devices, and a read
of /sys/bus/soc/devices/soc0/family currently shows
"Unknown". Fix the same.

Tony Lindgren 5b7610f235 ARM: OMAP2+: Fix wl12xx on dm3730-evm with mainline u-boot
I upgraded my u-boot and noticed that wl12xx stopped working.
Turns out the kernel is not setting the quirk for the MMC2
copy clock while the eariler bootloader I had was setting it.

Tero Kristo 50f59d07e9 ARM: OMAP4+: PRM: fix omap4 version of prm_save_and_clear_irqen
This was incorrectly reading the irq status registers during the save
and clear, instead of the irq enable. This worked because there is only
one user for the prcm interrupts currently, namely the io-chain. Whenever
the function was called, an io-chain interrupt was both pending and
enabled.

Tero Kristo 80d2518dfd ARM: OMAP2+: hwmod: fix deassert hardreset clkdm usecounting
Deasserting hardreset increases the usecount for the hwmod parent clockdomain
always, however usecount is only decreased at end in certain error cases.
This causes software supervised clockdomains to remain always on, preventing
idle. Fixed by always releasing the hwmods clockdomain parent when exiting
the function.

Kishon Vijay Abraham I 0717103e65 ARM: DRA7: hwmod_data: Fix hwmod data for pcie
Fixed hwmod data for pcie by having the correct module mode offset.
Previously this module mode offset was part of pcie PHY which was wrong.
Now this module mode offset was moved to pcie hwmod and removed the hwmod data
for pcie phy. While at that renamed pcie_hwmod to pciess_hwmod in order
to match with the name given in TRM.

This helps to get rid of the following warning
"omap_hwmod: pcie1: _wait_target_disable failed"

[Grygorii.Strashko@linaro.org: Found the issue that actually caused
 "omap_hwmod: pcie1: _wait_target_disable failed"]

Peter Ujfalusi 6931795238 ARM: omap2+: omap_hwmod: Set unique lock_class_key per hwmod
Add struct lock_class_key to omap_hwmod struct and use it to set unique
lockdep class per hwmod.
This will ensure that lockdep will know that each omap_hwmod->_lock should
be treated as separate class and will not give false warning about deadlock
or other issues due to nested use of hwmods.
DRA7x's ATL hwmod is one example for this since McASP can select ATL clock
as functional clock, which will trigger nested oh->_lock usage. This will
trigger false warning from lockdep validator as it is dealing with classes
and for it all hwmod clocks are the same class.

Linus Torvalds 2177033233 ARM: SoC fixes for 3.20-rc1
A few fixes that came in too late to make it into the first set of pull
 requests but would still be nice to have in -rc1. The majority of these
 are trivial build fixes for bugs that I found myself using randconfig
 testing, and a set of two patches from Uwe to mark DT strings as 'const'
 where appropriate, to resolve inconsistent section attributes.

Linus Torvalds 18a8d49973 The clock framework changes for 3.20 contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
 devices. Additionaly the framework core underwent a bit of surgery with
 two major changes. The boundary between the clock core and clock
 providers (e.g clock drivers) is now more well defined with dedicated
 provider helper functions. struct clk no longer maps 1:1 with the
 hardware clock but is a true per-user cookie which helps us tracker
 users of hardware clocks and debug bad behavior. The second major change
 is the addition of rate constraints for clocks. Rate ranges are now
 supported which are analogous to the voltage ranges in the regulator
 framework. Unfortunately these changes to the core created some
 breakeage. We think we fixed it all up but for this reason there are
 lots of last minute commits trying to undo the damage.

of_device_ids (i.e. compatible strings and the respective data) are not
supposed to change at runtime. All functions working with of_device_ids
provided by <linux/of.h> work with const of_device_ids. So mark the
non-const structs in arch/arm as const, too.

While at it also add some __initconst annotations.

Linus Torvalds 878ba61aa9 ARM: SoC platform changes
New and updated SoC support. Also included are some cleanups where the
 platform maintainers hadn't separated cleanups from new developent in
 separate branches.
 
 Some of the larger things worth pointing out:
 
 - A large set of changes from Alexandre Belloni and Nicolas Ferre
   preparing at91 platforms for multiplatform and cleaning up quite a
   bit in the process.
 - Removal of CSR's "Marco" SoC platform that never made it out to the
   market. We love seeing these since it means the vendor published
   support before product was out, which is exactly what we want!
 
 New platforms this release are:
 
 - Conexant Digicolor (CX92755 SoC)
 - Hisilicon HiP01 SoC
 - CSR/sirf Atlas7 SoC
 - ST STiH418 SoC
 - Common code changes for Nvidia Tegra132 (64-bit SoC)
 
 We're seeing more and more platforms having a harder time labelling
 changes as cleanups vs new development -- which is a good sign that
 we've come quite far on the cleanup effort. So over time we might start
 combining the cleanup and new-development branches more.

The dummy clock in arch/arm/mach-omap2 is made redundant by the OMAP3+

clk-private.h which will be removed.

Tomeu Vizoso 035a61c314 clk: Make clk API return per-user struct clk instances
Moves clock state to struct clk_core, but takes care to change as little API as
possible.

struct clk_hw still has a pointer to a struct clk, which is the
implementation's per-user clk instance, for backwards compatibility.

The struct clk that clk_get_parent() returns isn't owned by the caller, but by
the clock implementation, so the former shouldn't call clk_put() on it.

Because some boards in mach-omap2 still register clocks statically, their clock
registration had to be updated to take into account that the clock information
is stored in struct clk_core now.

Tony Lindgren 4d38bd1237 ARM: OMAP2+: Add dm816x hwmod support
Add minimal hwmod support that works at least on dm8168. This
is based on the code in the earlier TI CDP tree, and an earlier

I've set up things to work pretty much the same way as for

This patch adds required definitions and structures for clockdomain
initialization, so omap3xxx_clockdomains_init() was substituted by
new ti81xx_clockdomains_init() while early initialization of
TI81XX platform.

Note that we now need to have 81xx in a separate CONFIG_SOC_TI81XX
block instead inside the ifdef block for omap3 to avoid make
randconfig build errors.

for earlycon to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS.

On DRA7 UART3 hwmod doesn't have this flag enabled, and atleast on
BeagleBoard-X15, where we use UART3 for console, boot fails with
DEBUG_LL enabled. Enable DEBUG_OMAP4UART3_FLAGS for UART3 hwmod.

For using DEBUG_LL, enable CONFIG_DEBUG_OMAP4UART3 in menuconfig.

Tony Lindgren 549f95ed20 ARM: OMAP3: Add back Kconfig option MACH_OMAP3517EVM for ASoC
We still have SND_OMAP_SOC_AM3517EVM depending on MACH_OMAP3517EVM,
so let's keep MACH_OMAP3517EVM Kconfig option around for a little
bit longer.

This removes the dependency between ARM SoC changes and the ASoC
changes, and allows the following three options for the driver:

1. Update the driver for device tree based booting

2. Initialize the driver with legacy platform data, then update
   the driver for device tree based booting

3. Just remove the driver if there are no audio users for
   3517-evm board

In preparation for having init_card() called for all card types (not
just SDIO), change pandora_wl1251_init_card() so it checks whether the

Marc Zyngier 0fb22a8fb7 ARM: OMAP: Work around hardcoded interrupts
Commit 9a1091ef00 ("irqchip: gic: Support hierarchy irq domain")
changed the GIC driver to use a non-legacy IRQ domain on DT
platforms. This patch assumes that DT-driven systems are getting
all of their interrupts from device tree.

Turns out that OMAP has quite a few hidden gems, and still uses
hardcoded interrupts despite having fairly complete DTs.

This patch attempts to work around these by offering a translation
method that can be called directly from the hwmod code, if present.
The same hack is sprinkled over PRCM and TWL.

It isn't pretty, but it seems to do the job without having to add
more hacks to the interrupt controller code.

Tested on OMAP4 (Panda-ES) and OMAP5 (UEVM5432).

This patch implements generic DT L2C initialisation (the one from
init_IRQ in arch/arm/kernel/irq.c) for Omap4 and AM43 platforms and
kills the SoC specific stuff in arch/arm/mach-omap2/omap4-common.c.

Tony Lindgren c27964b5d2 ARM: OMAP2+: Fix ti81xx class type
Otherwise it will return true for cpu_is_omap34xx() which we don't
want for the clocks and hwmod. It's closer to am33xx for the clocks
and hwmod than to the omap34xx. We also want to be able to detect
814x and 816x separately as at least the clocks are different with
814x using a apll and 816x using a fapll for the source clocks.

Note that we can also remove omap3xxx_clk_init() call as it's wrong
and ti81xx are booting in device tree only mode.
