Andrew F. Davis 80570ce847 ARM: dts: keystone-k2l: Move keystone_dsp_gpio to under device-state-control
The keystone_irq node describes a device that is a member of the device
state control module address space. As such, it should not be a member
of soc0 bus but instead a sub-node of device-state-control.

This move also fixes warnings about not having a reg property. Now
that this is a sub-node of device-state-control, a syscon type node,
we add this reg property but relative to the syscon base, this way
when the dt-binding/driver are updated we can drop the non-standard
gpio,syscon-dev property completely and simply use get_resource() in
the driver.

Nishanth Menon eb08c33f9f ARM: dts: keystone*: Use a single soc0 instance
Provide a soc0 node and reference the same to simplify dts. This also
resolves the following warnings when built with W=1:
arch/arm/boot/dts/keystone-k2hk-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name
arch/arm/boot/dts/keystone-k2l-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name
arch/arm/boot/dts/keystone-k2e-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name
arch/arm/boot/dts/keystone-k2g-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name
arch/arm/boot/dts/keystone-k2g-ice.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name

NOTE: Though we can reformat files by reducing 1 level of indent due to
the use of soc0 phandle, we omit that change to prevent un-necessary
churn in code base.

Rob Herring 8dccafaa28 arm: dts: fix unit-address leading 0s
Fix dtc warnings for 'simple_bus_reg' due to leading 0s. Converted using
the following command:

perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find arch/arm/boot/dts -type -f -name '*.dts*'

Dropped changes to ARM, Ltd. boards LED nodes and manually fixed up some
occurrences of uppercase hex.

Suman Anna a6f0102bb6 ARM: dts: keystone-k2l: Add DSP nodes
The Keystone 2 66AK2L SoCs have 4 TMS320C66x DSP Core Subsystems
(C66x CorePacs), each with a 1.0 GHz or 1.2 GHz C66x Fixed /
Floating-Point DSP Core, and 32 KB of L1P & L1D SRAMs and a 1 MB
L2 SRAM. Add the DT nodes for these DSP processor sub-systems.
The processors do not have an MMU, and use various IPC Generation
registers and shared memory for inter-processor communication.
The aliases with a stem 'rproc' have also been added for all the
DSPs, they provide a fixed remoteproc id to each DSP processor.

Murali Karicheri 791229f1d5 ARM: dts: keystone-k2l: fix broken Ethernet due to disabled OSR
Ethernet networking on K2L has been broken since v4.11-rc1. This was
caused by commit 32a34441a9 ("ARM: keystone: dts: fix netcp clocks
and add names"). This commit inadvertently moves on-chip static RAM
clock to the end of list of clocks provided for netcp. Since keystone
PM domain support does not have a list of recognized con_ids, only the
first clock in the list comes under runtime PM management. This means
the OSR (On-chip Static RAM) clock remains disabled and that broke
networking on K2L.

The OSR is used by QMSS on K2L as an external linking RAM. However this
is a standalone RAM that can be used for non-QMSS usage (as well as from
DSP side). So add a SRAM device node for the same and add the OSR clock
to the node.

Remove the now redundant OSR clock node from netcp.

To manage all clocks defined for netCP's use by runtime PM needs keystone
generic power domain (genpd) driver support which is under works.
Meanwhile, this patch restores K2L networking and is correct irrespective
of any future genpd work since OSR is an independent module and not part
of NetCP anyway.

Suman Anna 2ae4dad352 ARM: dts: keystone-k2l: Add PSC reset controller node
The Power Sleep Controller (PSC) module contains specific
memory-mapped registers that can be used to perform reset
management using specific bits for the DSPs available on the
SoC. The PSC is defined using a syscon node, and the reset
functionality is defined using a child syscon reset controller
node.

Add this syscon reset controller node as well as the reset
control data for the resets it supports for the 66AK2L SoCs.

Suman Anna 82d76b6a20 ARM: dts: keystone-k2l: Reserve MSM RAM for boot monitor
The Keystone 2 boot monitor uses 32 KB of the MSM RAM @ 0x0c1f8000
on 66AK2L SoCs, so add a reserved child node for the same.

This address is aligned to the values used within the latest boot
monitor firmware [1] as of commit cf8b431e8b3b ("soc: Move load
address to end of MSMC").

Add the RAM managed by the Multicore Shared Memory Controller (MSMC)

specific MSM memory range needed by a software module ought to be
reserved using an appropriate child node.

David Lechner 1dd5581354 ARM: dts: keystone: Add "ti,da830-uart" compatible string
The TI Keystone SoCs have extra UART registers beyond the standard 8250
registers, so we need a new compatible string to indicate this. Also, at
least one of these registers uses the full 32 bits, so we need to specify
reg-io-width in addition to reg-shift.

"ns16550a" is left in the compatible specification since it does work as
long as the bootloader configures the SoC UART power management registers.

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

Nishanth Menon 5edafc2982 ARM: dts: k2*: Rename the k2* files to keystone-k2* files
As reported in [1], rename the k2* dts files to keystone-* files
this will force consistency throughout.

Script for the same (and hand modified for Makefile and MAINTAINERS
files):

do
	b=`basename $i`;
	git mv $i arch/arm/boot/dts/keystone-$b;
	sed -i -e "s/$b/keystone-$b/g" arch/arm/boot/dts/*[si]
done

NOTE: bootloaders that depend on older dtb names will need to be
updated as well.
