We currently have a different clock rate for droid4 compared to the
stock v3.0.8 based Android Linux kernel:
# cat /sys/kernel/debug/clk/dpll_*_m7x2_ck/clk_rate
266666667
307200000
# cat /sys/kernel/debug/clk/l3_gfx_cm:clk:0000:0/clk_rate
307200000
Let's fix this by configuring sgx to use 153.6 MHz instead of 307.2 MHz.
Looks like also at least duover needs this change to avoid hangs, so
let's apply it for all 4430.
This helps a bit with thermal issues that seem to be related to memory
corruption when using sgx. It seems that other driver related issues
still remain though.

We can power off l4_abe domain when not in use when we configure it for
genpd. And with that change, we can now also drop the old unused legacy
platform data.
Note that we also need to now use "simple-pm-bus" instead of "simple-bus"
for PM runtime to get enabled for the bus.

Pull ARM SoC DT updates from Arnd Bergmann:
"As usual, there are many patches addressing minor issues in existing
DTS files, such as DTC warnings, or adding support for additional
peripherals.
There are three added SoCs in existing product families:
- Amazon:
Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs,
otherwise known as AL73400 or first-generation Graviton, and
following the already supported Cortex-A1`5 and Cortex-A57 based
Alpine chips. This one is added together with the official
Evaluation platform.
- Qualcomm:
The Snapdragon SDM630 platform is a family of mid-range mobile
phone chips from 2017 based on Cortex-A53 or Kryo 260 CPUs. A total
of five end-user products are added based on these, all Android
phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and XA2 Ultra.
- Renesas:
RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G
family, and apparently closely related to the RZ/G2N and RZ/G2M
models we already support but has a faster GPU and additional
on-chip peripherals. It is added along with the HopeRun HiHope
RZ/G2H development board
A small number of new boards for already supported SoCs also debut:
- Allwinner sunxi:
Only one new machine, revision v1.2 of the Pine64 PinePhone
(non-Android) smartphone, containing minor changes compared to
earlier versions.
- Amlogic Meson:
WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box
- Aspeed:
EthanolX is AMD's EPYC data center rerence platform, using an
ASpeed AST2600 baseboard management controller.
- Mediatek:
Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook based
on the MT8183 (Helio P60t) SoC.
- Nvidia Tegra:
ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android
tablets from around 2012 using Tegra 3 and Tegra 2, respectively.
Thanks to PostmarketOS, these can now run mainline kernels and
become useful again.
The Jetson Xavier NX Developer Kit uses a SoM and carrier board for
the Tegra194, their latest 64-bit chip based on Carmel CPU cores
and Volta graphics.
- NXP i.MX:
Five new boards based on the 32-bit i.MX6 series are added: The
MYiR MYS-6ULX single-board computer, and four different models of
industrial computers from Protonic.
- Qualcomm:
MikroTik RouterBoard 3011 is a rackmounted router based on the
32-bit IPQ8064 networking SoC
Three older phones get added, the Snapdragon 808 (msm8992) based
Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running
Windows Phone, and the Snapdragon 810 (msm8994) based Sony Xperia
Z5.
- Renesas:
In addition to the HiHope RZ/G2H board mentioned above, we gain
support for board versions 3.0 and 4.0 of the earlier RZ/G2M and
RZ/G2N reference boards. Beacon EmbeddedWorks adds another
SoM+Carrier development board for RZ/G2M.
- Rockchips:
Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it is
based on, using the high-end 32-bit rk3288 SoC.
Notable updates to existing platforms are usually for added on-chip
peripherals, including:

The compatible property for the DSP node is updated to match

node to the ocp node to better reflect the connectivity from
MPU side.
The node is updated with the 'ti,bootreg', 'clocks', 'resets',
'iommus', 'mboxes' and 'firmware' properties. Note that the
node does not have any 'reg' or 'reg-names' properties since
it doesn't have any L2 RAM memory, but only Unicaches.
The node is disabled for now, and should be enabled as per
the individual product configuration in the corresponding

We can now init system timers using the dmtimer and 32k counter
based on only devicetree data and drivers/clocksource timers.
Let's configure the clocksource and clockevent, and drop the old
unused platform data.
As we're just dropping platform data, and the early platform data
init is based on the custom ti,hwmods property, we want to drop
both the platform data and ti,hwmods property in a single patch.
Since the dmtimer can use both 32k clock and system clock as the
source, let's also configure the SoC specific default values. The
board specific dts files can reconfigure these with assigned-clocks
and assigned-clock-parents as needed.

The display subsystem (DSS) is in a 16MB interconnect target module
mapped to l4 and l3 buses. We are only using the l3 port as recommended
by the TRM. So there is no need to configure l4 ranges like we've done
for l4 ABE instance for example.
Initially let's just update the top level dss node to probe with ti-sysc
interconnect target module driver. The child nodes are still children
of dispc, only the node indentation changes for them now along with
using the reg range provided by top level dss.
Let's also add add a note about using only the l3 access without l4
as noted in the TRM.

The device node name should reflect generic class of a device so rename
the "ocmcram" node to "sram". This will be also in sync with upcoming DT
schema. No functional change.

Add PRM nodes for omap4 series of SoCs. These are initially used to
support reset control for some of the nodes, but will be extended
later to add powerdomain control and support for PRCM irqs among
other things.

I've tested that the interconnect target module enables and idles
just fine when probed with ti-sysc with PM runtime control via sys:
# echo on > $(find /sys -name control | grep \/5601)
# rwmem 0x56000024
0x56000024 = 0x00010200 # SGX540 CORE_REVISION
# echo auto > $(find /sys -name control | grep \/5601)
# rwmem 0x56000024
And when idled, it will produce "Bus error" as expected.

We can now add l4 abe interconnect hierarchy and ti-sysc data with
ti-sysc driver supporting external optional clocks needed by mcpdm.
This data is generated based on platform data from a booted system
and the interconnect acces protection registers for ranges. To avoid
regressions, we initially validate the device tree provided data
against the existing platform data on boot.
Note that mcpdm we now need to enable at module level only for devices
that have the external pdmclk wired from the PMIC as the clock is
needed for the module to be accessible.

With l4 interconnect hierarchy and ti-sysc interconnect target module
data in place, we can simply move all the related child devices to
their proper location and enable probing using ti-sysc.
In general the first child device address range starts at range 0
from the ti-sysc interconnect target so the move involves adjusting
the child device reg properties for that.
And we cannot yet move mmu_dsp until we have a proper reset controller
driver for rstctrl registers.
In case of any regressions, problem devices can be reverted to probe
with legacy platform data as needed by moving them back and removing
the related interconnect target module node.

Before updating wdt2 to probe with ti-sysc we want to have wdt3
probed with ti-sysc to avoid having them unnecessarily swap order.
With ti-sysc, we probe child devices at module_init time while
and until l4 abe interconnect is converted to use ti-sysc, wdt3
will probe earlier with legacy platform data.

The size of these modules is 0x2000, not 0x3000. The extra 0x1000
after 0x2000 is for the interconnect target agent which is a separate
device.

Pull "Few omap interconnect dts fixes for v4.16 merge window" from
Tony Lindgren:
Now that we have the dts clocks for the clkctrl clock and the
interconnect binding, we need to update the existing ti-sysc
users according to the binding to make it usable for drivers.
Apologies for not being able to send this earlier but it took
me few revisions to get the smartreflex changes right and
tested with yet to be posted patches to make smartreflex probe
with dts and I wanted to have it sit in next for a while to make
sure we're not introducing regressions for legacy platform data
based booting.
Note that this is based on a merge with commit 20a2742e5784
("dt-bindings: ti-sysc: Update binding for timers and capabilities")
to avoid a merge conflict with the binding changes.
* tag 'omap-for-v4.16/dt-clk-dts-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:

ARM: dts: Fix smartreflex compatible for omap3 shared mpu-iva instance
dt-bindings: ti-sysc: Update binding for timers and capabilities
|

Let's update the existing users with features and clock data as
specified in the binding. This is currently the smartreflex for most
part, and also few omap4 modules with no child device driver like
mcasp, abe iss and gfx.
Note that we had few mistakes that did not get noticed as we're still
probing the SmartReflex driver with legacy platform data and using
"ti,hwmods" legacy property for ti-sysc driver.
So let's fix the omap4 and dra7 smartreflex registers as there is no
no revision register.
And on omap4, the mcasp module has a revision register according to
the TRM.
And for omap34xx we need a different configuration compared to 36xx.
And the smartreflex on 3517 we've always kept disabled so let's
remove any references to it.
