Highlights:
----------
MPU part:
-Add PWM support on DK2 board.
-Add counter support to STM32 timers.
-Add support of SDMMC 2&3 instances based on "arm,pl18x". SDMMC2 is
connected to eMMC on ED1 board. SDMMC3 is connected to the GPIO
extension connector on EV1 & DKx boards.
-Add ADC support on ED1 board.
-Update devicetree files split to better fit to STM32MP15 SOC & boards
diversity.
-Fix issues seen during YAML validation.
-Enable Ethernet (MAC) TX clock gating during low-power mode.
-Enable USB OTG HS support on DKx boards.
-Enable USB Host EHCI on DKx boards.

Drop more legacy platform data for omaps for v5.6 merge window
We can now probe devices with ti-sysc interconnect driver and dts
data, and can continue dropping the related platform data and custom
ti,hwmods dts property for various devices.
And related to that, we finally can remove the legacy sdma support in
favor of using the dmaengine driver only. I was planning to send the
sdma changes separately, but that would have produced a pile of
pointless merge conflicts, so I decided it's best to resolve it locally.

Drop all "ES" references next to part numbers, as they are implied by

Note that the device tree cannot be booted directly with
the original (Samsung) bootloader. It keeps the L2 cache turned on,
which causes the kernel to hang shortly after decompression.
As a workaround I have created a port of (mainline) U-Boot,
which locks the L2 cache before booting Linux. At the moment it does not
replace the Samsung bootloader, instead we let the original bootloader
load U-Boot as an another (intermediate) bootloader.
Another advantage of this is that U-Boot has proper device tree support,
so we do not need to hardcode the kernel command line in the device tree.

ARM: dts: ux500: Add device tree include for AB8505
AB8505 is a slightly newer version of AB8500.
Overall it is quite similar, but there are some differences like
the number of GPIOs and regulators. Therefore we need a separate
device tree definition for devices making use of AB8505.
The AB8500-specific nodes were moved out of ste-dbx5x0.dtsi in
commit a46f7c6762d8 ("ARM: dts: ux500: Move ab8500 nodes to ste-ab8500.dtsi").
Add a new "ste-ab8505.dtsi" device tree include in a similar way.
Keep the battery/charging related sub-devices disabled by default
since they require additional configuration to work correctly.
The pin configuration for HREF boards with AB8505 was added in
commit 77ad9dfc2c7e ("ARM: ux500: move last AB8505 set-up to DT").
As the commit message notes, it was unused back then and it has
remained so even today, especially considering AB8505 did not have
proper device tree support until recently.
We are now preparing to add support for some Samsung smartphones
that are using AB8505. However, they use different pin configs
because using ste-href-ab8505.dtsi is known to break UART.
There were not many HREFs with AB8505, so at this point it seems
unlikely that we will ever make use of this include. Remove it.

ARM: OMAP2+: use separate IOMMU pdata to fix DRA7 IPU1 boot
The IPU1 MMU has been using common IOMMU pdata quirks defined and
used by all IPU IOMMU devices on OMAP4 and beyond. Separate out the
pdata for IPU1 MMU with the additional .set_pwrdm_constraint ops
plugged in, so that the IPU1 power domain can be restricted to ON
state during the boot and active period of the IPU1 remote processor.
This eliminates the pre-conditions for the IPU1 boot issue as
described in commit afe518400bdb ("iommu/omap: fix boot issue on
remoteprocs with AMMU/Unicache").
NOTE:
1. RET is not a valid target power domain state on DRA7 platforms,
and IPU power domain is normally programmed for OFF. The IPU1
still fails to boot though, and an unclearable l3_noc error is
thrown currently on 4.14 kernel without this fix. This behavior
is slightly different from previous 4.9 LTS kernel.
2. The fix is currently applied only to IPU1 on DRA7xx SoC, as the
other affected processors on OMAP4/OMAP5/DRA7 are in domains
that are not entering RET. IPU2 on DRA7 is in CORE power domain
which is only programmed for ON power state. The fix can be easily
scaled if these domains do hit RET in the future.
3. The issue was not seen on current DRA7 platforms if any of the
DSP remote processors were booted and using one of the GPTimers
5, 6, 7 or 8 on previous 4.9 LTS kernel. This was due to the
errata fix for i874 implemented in commit 1cbabcb9807e ("ARM:
DRA7: clockdomain: Implement timer workaround for errata i874")
which keeps the IPU1 power domain from entering RET when the
timers are active. But the timer workaround did not make any
difference on 4.14 kernel, and an l3_noc error was seen still
without this fix.

ARM: OMAP2+: Add workaround for DRA7 DSP MStandby errata i879
Errata Title:
i879: DSP MStandby requires CD_EMU in SW_WKUP
Description:
The DSP requires the internal emulation clock to be actively toggling
in order to successfully enter a low power mode via execution of the
IDLE instruction and PRCM MStandby/Idle handshake. This assumes that
other prerequisites and software sequence are followed.
Workaround:
The emulation clock to the DSP is free-running anytime CCS is connected
via JTAG debugger to the DSP subsystem or when the CD_EMU clock domain
is set in SW_WKUP mode. The CD_EMU domain can be set in SW_WKUP mode
via the CM_EMU_CLKSTCTRL [1:0]CLKTRCTRL field.
Implementation:
This patch implements this workaround by denying the HW_AUTO mode
for the EMU clockdomain during the power-up of any DSP processor
and re-enabling the HW_AUTO mode during the shutdown of the last
DSP processor (actually done during the enabling and disabling of
the respective DSP MDMA MMUs). Reference counting has to be used to
manage the independent sequencing between the multiple DSP processors.
This switching is done at runtime rather than a static clockdomain
flags value to meet the target power domain state for the EMU power
domain during suspend.
Note that the DSP MStandby behavior is not consistent across all
boards prior to this fix. Please see commit 45f871eec6c0 ("ARM:
OMAP2+: Extend DRA7 IPU1 MMU pdata quirks to DSP MDMA MMUs") for
details.
