Based on Tony Lindgren's work for omap34xx, this patch applies the same
functionality to the AM3517.
The following can be tested via sysfs with the following to ensure the SGX
module gets enabled and disabled properly:
0x00010201
Bus error

The AM3517 has a different OTG controller location than the OMAP3,
which is included from omap3.dtsi. This results in a hwmod error.
Since the AM3517 has a different OTG controller address, this patch
disabes one that is isn't available.

A previous patch removed OMAP clock aliases that were perceived
to be unnecessary. Unfortunately, it broke the ethernet on the
am3517-evm. This patch enables the MDIO clock and EMAC clock.

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: Update ti-sysc data for existing users
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.

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have
leading "0x"
and
Warning (unit_address_format): Node /XXX unit name should not have
leading 0s
Converted using the following command:
$ find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec \
sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" \
-e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C
For simplicity, two sed expressions were used to solve each warnings
separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before
the the opening curly brace:
https://elinux.org/Device_Tree_Linux#Linux_conventions
This will solve as a side effect warning:
Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format
error, expected "<lower>"
This is a follow up to commit 4c9847b7375a ("dt-bindings: Remove leading
0x from bindings notation")

Drivers using pinctrl-single,pins have #pinctrl-cells = <1>, while
pinctrl-single,bits need #pinctrl-cells = <2>.
Note that this patch can be optionally applied separately from the
driver changes as the driver supports also the legacy binding without
#pinctrl-cells.

According to the technical reference manual for AM35xx system
controller module (SCM) PADCONFS core registers are divided in two
regions: 0x48002030..0x48002268 and 0x480025d8..0x480025fc.
First region is the same for all omap3 SoC and is described in omap3.dtsi.
The second region is the same as in omap34xx (see omap34xx.dtsi)
and omap35xx. The patch adds missing description for the second region.
This patch was tested on AM3517.

This patch creates an l4_core interconnect for OMAP3, and moves some
of the generic peripherals under it. System control module nodes are
moved under this new interconnect also, and the SCM clock layout
is changed to use the renamed SCM node as the clock provider.

Looks like on 3517 davinci_emac MAC address registers have a

AM3517 inherits OMAP3 dts file, but does not have all the IPs
that are present on OMAP3. This patch disables the following
absent IPs for AM3517: Mailbox, IVA, MMU_ISP, MPU_IVA SmartReflex.
A label had to be added for IVA node in omap3.dtsi to be able to
get a reference to the node for disabling.
Otherwise we get the following warnings during booting:
platform iva.2: Cannot lookup hwmod 'iva'
platform 48094000.mailbox: Cannot lookup hwmod 'mailbox'
platform 480bd400.mmu: Cannot lookup hwmod 'mmu_isp'

AM35xx now uses the clock data from device tree. Most of the data is
shared with OMAP3xxx, but as there is some delta, a new base .dtsi
file is also created for the SoC.

On am3517 there are some extra devices compared to omap3.dtsi that
we currently have not defined. Let's fix that by adding am3517.dtsi
file.
