The PRUSSs on AM57xx SoCs contain an MDIO controller that can
be used to control external PHYs associated with the Industrial
Ethernet peripherals within each PRUSS. The MDIO module used
within the PRU-ICSS is an instance of the MDIO Controller used
in TI Davinci SoCs. The same bus frequency of 1 MHz is chosen as
the regular MDIO node.
The nodes are added in the common am57-pruss.dtsi file and enabled
by default, but are disabled in all the existing AM57xx board dts
files. These nodes need pinctrl lines, and so should be enabled
only on boards where they are actually wired and pinned out for
PRUSS Ethernet. Any new board dts file should disable these if
they are not sure.

Add the DT nodes for the PRU-ICSS1 and PRU-ICSS2 processor subsystems
that are present on AM57xx family of SoCs. Each PRU-ICSS instance is
represented by a pruss node and other child nodes. The two PRU-ICSSs
are identical to each other. They are not supported on DRA7xx SoCs in
general, so the nodes are added under the respective interconnect target
module nodes in a common am57-pruss.dtsi file. The file is already
included only in the AM57xx related board files.
The PRU-ICSSs on AM57xx are very similar to the PRUSS in AM33xx and AM437x
except for variations in the RAM sizes and the number of interrupts coming
into the MPU INTC. The interrupt events into the PRU-ICSS also requires
programming of the corresponding crossbars properly.
The PRUSS subsystem node contains the entire address space. The various
sub-modules of the PRU-ICSS are represented as individual child nodes
(so platform devices themselves) of the PRUSS subsystem node. These
include the two PRU cores and the interrupt controller. All the Data
RAMs are represented within a child node of its own named 'memories'
without any compatible. The Real Time Media Independent Interface
controller (MII_RT), and the CFG sub-module are represented as syscon
nodes. The PRUSS CFG module has a clock mux for IEP clock, this clk
node is added under the CFG child node 'clocks'. The default source
for this mux clock is the ICSS_IEP_CLK clock.
The DT nodes use all standard properties. The regs property in the PRU
nodes define the addresses for the Instruction RAM, the Debug and Control
sub-modules for that PRU core. The firmware for each PRU core is defined
through a 'firmware-name' property.
The default names for the firmware images for each PRU core are defined
as follows (these can be adjusted either in derivative board dts files or
through sysfs at runtime if required):
PRU-ICSS1 PRU0 Core: am57xx-pru1_0-fw
PRU-ICSS1 PRU1 Core: am57xx-pru1_1-fw
PRU-ICSS2 PRU0 Core: am57xx-pru2_0-fw
PRU-ICSS2 PRU1 Core: am57xx-pru2_1-fw
Note:
1. There are few more sub-modules like the Industrial Ethernet Peripheral
(IEPs), MDIO, UART, eCAP that do not have bindings and so will be added
in the future.
2. The PRUSS INTC on AM57xx SoCs also connect the host interrupts 6 and 7
as possible DMA events, so use the 'ti,irqs-reserved' property in
derivative board dts files _if_ any of them should not be handled by
the host OS.

The AM4376+ SoCs have a second smaller PRU-ICSS subsystem (PRUSS0) in
addition to the primary PRUSS1 instance. The PRUSS0 has less DRAM
per PRU, and no Shared DRAM among other minor differences. The IEP
and MII_RT modules even though present within the IP are not pinned
out.
This PRUSS0 instance has a weird SoC integration. It shares the same
L3 OCP interconnect interface with PRUSS1, and also shares its reset
line and clocks. Any external accesses from PRUSS0 requires the PRUSS1's
PRUSS_SYSCFG register to be programmed properly. That said, it is its
own IP instance (a cut-down version), and so it has been added as an
independent node (sibling node to PRUSS1 node) and a child node of the
corresponding PRUSS target module interconnect node. This allows the
PRUSS0 instance to be enabled/disabled independently of the PRUSS1
instance.
The nodes are added under the corresponding interconnect target module
node in the common am4372 dtsi file. The PRU-ICSS instances are not
supported on AM4372 SoC though in the AM437x family, so the interconnect
target module node should be disabled in any derivative board dts file that
uses AM4372 SoCs. The individual PRUSS node can be disabled in the
corresponding board dts file if desired.
The default names for the firmware images for each PRU core are defined
as follows (these can be adjusted either in derivative board dts files or
through sysfs at runtime if required):
PRU-ICSS0 PRU0 Core: am437x-pru0_0-fw
PRU-ICSS0 PRU1 Core: am437x-pru0_1-fw
Note:
1. There are few more sub-modules like the Industrial Ethernet Peripheral
(IEP), eCAP, UART, that do not have bindings and so will be added in the
future. Only UART is pinned out, so others should be added in disabled
state if added.
2. The PRUSS0 INTC on AM437x SoCs routes the host interrupt 5 to the other
PRUSS1, so it is already marked reserved through the 'ti,irqs-reserved'
property.

Add the DT node for the PRU-ICSS1 instance on the AM437x family of SoCs.
Each PRU-ICSS instance is represented by a pruss node and other child
nodes. The nodes are added under the interconnect target module node in
the common am4372 dtsi file. The PRU-ICSS instances are supported only
on AM4376+ SoCs though in the AM437x family, so the interconnect target
module node should be disabled in any derivative board dts file that
uses AM4372 SoCs.
The PRU-ICSS1 on AM437x is very similar to the PRUSS in AM33xx, except
for variations in the RAM sizes, bus addresses and the number of
interrupts coming into the MPU INTC (host interrupt 5 is routed to
the other PRUSS instead of MPU).
The PRUSS subsystem node contains the entire address space. The various
sub-modules of the PRU-ICSS are represented as individual child nodes
(so platform devices themselves) of the PRUSS subsystem node. These

node is added under the CFG child node 'clocks'. The default source
for this mux clock is the PRU_ICSS_IEP_GCLK clock.
The DT nodes use all standard properties. The regs property in the PRU

and ADC1; 6 and 7 as possible DMA events, so use the 'ti,irqs-reserved'

no use-cases defined to use a particular PRU core or the whole
PRU-ICSS subsystem itself if both its PRU cores are unused.

The PRUSS on AM335x SoCs has a MDIO sub-module that can be used
to control external PHYs associated with the Industrial Ethernet
peripherals within the PRUSS. The MDIO module used within the
PRU-ICSS is an instance of the MDIO Controller used in TI Davinci
SoCs. The same bus frequency of 1 MHz is chosen as the regular
MDIO node.
The node is added to the common am33xx-l4.dtsi file and is disabled.
This needs to be enabled in the respective board files using the
relevant AM335x SoCs supporting PRUSS and where the ethernet is
pinned out and connected properly.

Add the DT nodes for the PRU-ICSS on AM33xx family of SoCs. The AM33xx
SoCs contain a single PRU-ICSS instance and is represented by a pruss
node and other child nodes. PRU-ICSS is supported only on AM3356+ SoCs
though in the AM33xx family, so the nodes are added under the
corresponding disabled interconnect target module node in the common
am33xx-l4 dtsi file. The target module node should be enabled in only
those derivative board files that use a SoC containing PRU-ICSS.
The PRUSS subsystem node contains the entire address space. The various
sub-modules of the PRU-ICSS are represented as individual child nodes
(so platform devices themselves) of the PRUSS subsystem node. These
include the two PRU cores and the interrupt controller. All the Data
RAMs are represented within a child node of its own named 'memories'
without any compatible. The Real Time Media Independent Interface
controller (MII_RT), and the CFG sub-module are represented as syscon
nodes. The PRUSS CFG module has a clock mux for IEP clock, this clk
node is added under the CFG child node 'clocks'. The default source
for this mux clock is the PRU_ICSS_IEP_GCLK clock.
The DT nodes use all standard properties. The regs property in the PRU
nodes define the addresses for the Instruction RAM, the Debug and Control
sub-modules for that PRU core. The firmware for each PRU core is defined
through a 'firmware-name' property.
The default names for the firmware images for each PRU core are defined
as follows (these can be adjusted either in derivative board dts files
or through sysfs at runtime if required):
PRU-ICSS PRU0 Core: am335x-pru1_0-fw
PRU-ICSS PRU1 Core: am335x-pru1_1-fw
Note:
1. There are few more sub-modules like the Industrial Ethernet Peripheral
(IEP), MDIO, UART, eCAP that do not have bindings and so will be added
in the future.
2. The PRUSS INTC on AM335x SoCs also connect the host interrupts 0 to
TSC_ADC; 6 and 7 as possible DMA events, so use the 'ti,irqs-reserved'
property in derivative board dts files _if_ any of them should not be
handled by the host OS.

The operating points should correspond to the actual frequencies
supported for the CPU. Other patches have fixed so these are
rounded and reported properly, this fixes the device trees to
match.
The Codina variant has a lower frequency than other devices so

Since commit 1b6b26ae70 ("pipe: fix and clarify pipe write wakeup
logic") we have sanitized the pipe write logic, and would only try to
wake up readers if they needed it.
In particular, if the pipe already had data in it before the write,
there was no point in trying to wake up a reader, since any existing
readers must have been aware of the pre-existing data already. Doing
extraneous wakeups will only cause potential thundering herd problems.
However, it turns out that some Android libraries have misused the EPOLL
interface, and expected "edge triggered" be to "any new write will
trigger it". Even if there was no edge in sight.
Quoting Sandeep Patil:
"The commit 1b6b26ae70 ('pipe: fix and clarify pipe write wakeup
logic') changed pipe write logic to wakeup readers only if the pipe
was empty at the time of write. However, there are libraries that
relied upon the older behavior for notification scheme similar to
what's described in [1]
One such library 'realm-core'[2] is used by numerous Android
applications. The library uses a similar notification mechanism as GNU
Make but it never drains the pipe until it is full. When Android moved
to v5.10 kernel, all applications using this library stopped working.
The library has since been fixed[3] but it will be a while before all
applications incorporate the updated library"
Our regression rule for the kernel is that if applications break from
new behavior, it's a regression, even if it was because the application
did something patently wrong. Also note the original report [4] by
Michal Kerrisk about a test for this epoll behavior - but at that point
we didn't know of any actual broken use case.
So add the extraneous wakeup, to approximate the old behavior.
[ I say "approximate", because the exact old behavior was to do a wakeup
not for each write(), but for each pipe buffer chunk that was filled
in. The behavior introduced by this change is not that - this is just
"every write will cause a wakeup, whether necessary or not", which
seems to be sufficient for the broken library use. ]
It's worth noting that this adds the extraneous wakeup only for the
write side, while the read side still considers the "edge" to be purely
about reading enough from the pipe to allow further writes.
See commit f467a6a664 ("pipe: fix and clarify pipe read wakeup logic")
for the pipe read case, which remains that "only wake up if the pipe was
full, and we read something from it".

This makes 'perf top' abort in some cases, and the right fix will
involve surgery that is too much to do at this stage, so revert for now
and fix it in the next merge window.
This reverts commit 2d6b74baa7.
