git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into fixes
ARM: OMAP2+: critical DRA7xx fix for v4.5-rc
Force the DRA7xx Ethernet internal clock source to stay enabled
per TI erratum i877:
http://www.ti.com/lit/er/sprz429h/sprz429h.pdf
Otherwise, if the Ethernet internal clock source is disabled, the
chip will age prematurely, and the RGMII I/O timing will soon
fail to meet the delay time and skew specifications for 1000Mbps
Ethernet.
This fix should go in as soon as possible.
Basic build, boot, and PM test results are available here:

git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v4.6/soc
ARM: OMAP2+: second set of hwmod changes for v4.6
These patches add RTC support for the AM43xx, and add support for
the DRA7xx eDMA controller's TPCC, TPTC0, and TPTC1 IP blocks.
Also included is a workaround for PRCM hardreset control of the DRA7xx
PCIe subsystem.
Note that I do not have a DRA7xx board, and therefore cannot
test any patches for that SoC family.
Basic build, boot, and PM test logs can be found here:
http://www.pwsan.com/omap/testlogs/omap-hwmod-b-for-v4.6/20160301021258/

Add hwmod data for the eDMA blocks:
- TPCC: Third-party channel controller
- TPTC0: Third-party transfer controller 0
- TPTC1: Third-party transfer controller 1
The TPCC's clock gating status follows the status of its clock and
power domain. This means that the hwmod code can not directly control
the TPCC enable/disable status.

Add a custom reset handler for DRA7x PCIeSS. This
handler is required to deassert PCIe hardreset lines
after they have been asserted.
This enables the PCIe driver to access registers after
PCIeSS has been runtime enabled without having to
deassert hardreset lines itself.
With this patch applied, used lspci to make sure
connected PCIe device enumerates on DRA74x and DRA72x
EVMs.

We still have some boards booting in legacy mode and they will need to have
the device/slave -> filter_fn mapping so we can convert the OMAP drivers
to use the new dmaengine API for requesting channels.
Only some OMAP24xx and OMAP3xxx boards can boot in legacy mode which means
we only need to provide the map for these SoCs.

If syscon_config.max_register is initialized like it should be, we have
omap_ctrl_read/write() fail with out of range register access at least
for omap3.
We have omap3.dtsi setting up a regmap range for scm_conf, but we now
have omap_ctrl_read/write() also attempt to use the regmap. However,
omap_ctrl_read/write() is also used for other register ranges in the
system control module (SCM).
Let's fix the issue by just removing the regmap_read/write() usage for
control module as suggested by Tero Kristo <t-kristo@ti.com>.

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.

The patch registers the rtc hwmod on AM437x chips. The RTC module is
physically present on the AM438x SoC used on AM43X-EPOS-EVM, but it is
permanently disabled. A secure RTC is used instead on these devices,
where needed. Hence adding it selectively using a separate list to get
RTC Module functional on the other am43x SoCs used on am437x-gp-evm
and am437x-sk-evm.

If a driver PM runtime is disabled via sysfs, and the module is
unloaded, PM runtime can't do anything to disable the device. Let's
let the interconnect disable the device on BUS_NOTIFY_UNBOUND_DRIVER.
Otherwise omap_device will produce and error on the following module
reload. This can be easily tested with something like:
# modprobe omap_hsmmc
# echo on > /sys/devices/platform/68000000.ocp/4809c000.mmc/power/control
# rmmod omap_hsmmc
# modprobe omap_hsmmc

Drivers using pm_runtime_use_autosuspend() may not get disabled after
-EPROBE_DEFER. On the following device driver probe, hardware state
is different from the PM runtime state causing omap_device to produce
the following error:
omap_device_enable() called from invalid state 1
And with omap_device and omap hardware being picky for PM, this will
block any deeper idle states in hardware.
Let's add a proper error message so driver writers can easily fix
their drivers for PM.
In general, the solution is to fix the drivers to follow the PM
runtime documentation:
1. For sections of code that needs the device disabled, use
pm_runtime_put_sync_suspend() if pm_runtime_set_autosuspend() has
been set.
2. For driver exit code, use pm_runtime_dont_use_autosuspend() before
pm_runtime_put_sync() if pm_runtime_use_autosuspend() has been
set.
Let's not return with 0 from _od_runtime_resume() as that will
eventually lead into new drivers with broken PM runtime that will
block deeper idle states on omaps.

We don't want to be writing to .text so it can be set rodata.
Fix error "Unable to handle kernel paging request at virtual address
c012396c" in wait_dll_lock_timed if CONFIG_DEBUG_RODATA is selected.
As these counters are for debugging only and unused, we can just
remove them.

The legacy-style mailbox device creation is supported currently
only for OMAP3, as all other SoCs are DT-boot only. Even on this
SoC, there are no client drivers that utilize these mailbox devices.
So, clean up the legacy-style mailbox device instantiation logic.
The mailbox devices are already present and supported for the DT
boot on OMAP3.

Pull more power management and ACPI updates from Rafael Wysocki:
"This includes fixes on top of the previous batch of PM+ACPI updates
and some new material as well.
From the new material perspective the most significant are the driver
core changes that should allow USB devices to stay suspended over
system suspend/resume cycles if they have been runtime-suspended
already beforehand. Apart from that, ACPICA is updated to upstream
revision 20160108 (cosmetic mostly, but including one fixup on top of
the previous ACPICA update) and there are some devfreq updates the
didn't make it before (due to timing).
A few recent regressions are fixed, most importantly in the cpuidle
menu governor and in the ACPI backlight driver and some x86 platform
drivers depending on it.
Some more bugs are fixed and cleanups are made on top of that.
Specifics:
- Modify the driver core and the USB subsystem to allow USB devices
to stay suspended over system suspend/resume cycles if they have
been runtime-suspended already beforehand and fix some bugs on top
of these changes (Tomeu Vizoso, Rafael Wysocki).
- Update ACPICA to upstream revision 20160108, including updates of
the ACPICA's copyright notices, a code fixup resulting from a
regression fix that was necessary in the upstream code only (the
regression fixed by it has never been present in Linux) and a
compiler warning fix (Bob Moore, Lv Zheng).
- Fix a recent regression in the cpuidle menu governor that broke it
on practically all architectures other than x86 and make a couple
of optimizations on top of that fix (Rafael Wysocki).
- Clean up the selection of cpuidle governors depending on whether or
not the kernel is configured for tickless systems (Jean Delvare).
- Revert a recent commit that introduced a regression in the ACPI
backlight driver, address the problem it attempted to fix in a
different way and revert one more cosmetic change depending on the
problematic commit (Hans de Goede).
- Add two more ACPI backlight quirks (Hans de Goede).
- Fix a few minor problems in the core devfreq code, clean it up a
bit and update the MAINTAINERS information related to it (Chanwoo
Choi, MyungJoo Ham).
- Improve an error message in the ACPI fan driver (Andy Lutomirski).
- Fix a recent build regression in the cpupower tool (Shreyas
Prabhu)"

In this past cycle the clk maintainers developed a good workflow for
handling the common case of patch submissions containing a new
drivers, new shared Device Tree header and a new Device Tree binding
description. This requires coordination with the Device Tree
maintainers and with the architecture maintainers (typically the
arm-soc tree in our case).
This explains the increase in changes to include/dt-bindings/... and
to Documentation/devicetree/bindings/clock/... coming from the clk

Adds a function that sets the pointer to dev_pm_domain in struct device
and that warns if the device has already finished probing. The reason
why we want to enforce that is because in the general case that can
cause problems and also that we can simplify code quite a bit if we can
always assume that.
This patch also changes all current code that directly sets the
dev.pm_domain pointer.

Commit 63aa945b1013 ("memory: omap-gpmc: Add Kconfig option for debug")
unified the GPMC debug for the SoCs with GPMC. The commit also left out
the option for HWMOD_INIT_NO_RESET as we now require proper timings for
GPMC to be able to remap GPMC devices out of address 0.
Unfortunately on Nokia N900, onenand now only partially works with the
device tree provided timings. It works enough to get detected but the
clock rate supported by the onenand chip gets misdetected. This in turn
causes the GPMC timings to be miscalculated and this leads into file
system corruption on N900.
Looks like onenand needs CS_CONFIG1 bit 27 WRITETYPE set for for sync
write. This is needed also for async timings when we write to onenand
with omap2_onenand_set_async_mode(). Without sync write bit set, the
async read for the onenand ONENAND_REG_VERSION_ID will return 0xfff.
Let's exit with an error if onenand rate is not detected. And let's
remove the extra call to omap2_onenand_set_async_mode() as we only need
to do this once at the end of omap2_onenand_setup_async().
