====================
Introduce IEP driver and packet timestamping support
This series introduces Industrial Ethernet Peripheral (IEP) driver to
support timestamping of ethernet packets and thus support PTP and PPS
for PRU ICSSG ethernet ports.
This series also adds 10M full duplex support for ICSSG ethernet driver.
There are two IEP instances. IEP0 is used for packet timestamping while IEP1
is used for 10M full duplex support.
This is v7 of the series [v1]. It addresses comments made on [v6].
This series is based on linux-next(#next-20230823).
Changes from v6 to v7:
*) Dropped blank line in example section of patch 1.
*) Patch 1 previously had three examples, removed two examples and kept only
one example as asked by Krzysztof.
*) Added Jacob Keller's RB tag in patch 5.
*) Dropped Roger's RB tags from the patches that he has authored (Patch 3 and 4)
Changes from v5 to v6:
*) Added description of IEP in commit messages of patch 2 as asked by Rob.
*) Described the items constraints properly for iep property in patch 2 as
asked by Rob.
*) Added Roger and Simon's RB tags.
Changes from v4 to v5:
*) Added comments on why we are using readl / writel instead of regmap_read()
/ write() in icss_iep_gettime() / settime() APIs as asked by Roger.
*) Added Conor's RB tag in patch 1 and 2.
Change from v3 to v4:
*) Changed compatible in iep dt bindings. Now each SoC has their own compatible
in the binding with "ti,am654-icss-iep" as a fallback as asked by Conor.
*) Addressed Andew's comments and removed helper APIs icss_iep_readl() /
writel(). Now the settime/gettime APIs directly use readl() / writel().
*) Moved selecting TI_ICSS_IEP in Kconfig from patch 3 to patch 4.
*) Removed forward declaration of icss_iep_of_match in patch 3.
*) Replaced use of of_device_get_match_data() to device_get_match_data() in
patch 3.
*) Removed of_match_ptr() from patch 3 as it is not needed.
Changes from v2 to v3:
*) Addressed Roger's comment and moved IEP1 related changes in patch 5.
*) Addressed Roger's comment and moved icss_iep.c / .h changes from patch 4
to patch 3.
*) Added support for multiple timestamping in patch 4 as asked by Roger.
*) Addressed Andrew's comment and added comment in case SPEED_10 in
icssg_config_ipg() API.
*) Kept compatible as "ti,am654-icss-iep" for all TI K3 SoCs
Changes from v1 to v2:
*) Addressed Simon's comment to fix reverse xmas tree declaration. Some APIs
in patch 3 and 4 were not following reverse xmas tree variable declaration.
Fixed it in this version.
*) Addressed Conor's comments and removed unsupported SoCs from compatible
comment in patch 1.
*) Addded patch 2 which was not part of v1. Patch 2, adds IEP node to dt
bindings for ICSSG.

For AM65x SR2.0 it's required to enable IEP1 in raw 64bit mode which is
used by PRU FW to monitor the link and apply w/a for 10M link issue.
Note. No public errata available yet.
Without this w/a the PRU FW will stuck if link state changes under TX
traffic pressure.
Hence, add support for 10M full duplex for AM65x SR2.0:
- add new IEP API to enable IEP, but without PTP support
- add pdata quirk_10m_link_issue to enable 10M link issue w/a.

Add packet timestamping TS and PTP PHC clock support.
For AM65x and AM64x:
- IEP1 is not used
- IEP0 is configured in shadow mode with 1ms cycle and shared between
Linux and FW. It provides time and TS in number cycles, so special
conversation in ns is required.
- IEP0 shared between PRUeth ports.
- IEP0 supports PPS, periodic output.
- IEP0 settime() and enabling PPS required FW interraction.
- RX TS provided with each packet in CPPI5 descriptor.
- TX TS returned through separate ICSSG hw queues for each port. TX TS
readiness is signaled by INTC IRQ. Only one packet at time can be requested
for TX TS.

This set introduces mac source and destination pedit set action offloads.
It also adds offload for ipv4 ttl and ipv6 hop limit pedit set action as
well pedit add actions that would result in the same semantics as
decrementing the ttl and hop limit.
v2:
- fix 'efx_tc_mangle' kdoc which was orphaned when adding 'efx_tc_pedit_add'.
- add description of 'match' in 'efx_tc_mangle' kdoc.
- correct some inconsistent kdoc indentation.

The conversion of the software based interrupt resend mechanism to

The missing check whether the descriptor is already queued causes

stale interrupt line in the worst case.

The switch to using hlist for managing software resend of interrupts
broke resend in at least two ways:
First, unconditionally adding interrupt descriptors to the resend list can
corrupt the list when the descriptor in question has already been
added. This causes the resend tasklet to loop indefinitely with interrupts
disabled as was recently reported with the Lenovo ThinkPad X13s after
threaded NAPI was disabled in the ath11k WiFi driver.
This bug is easily fixed by restoring the old semantics of irq_sw_resend()
so that it can be called also for descriptors that have already been marked
for resend.
Second, the offending commit also broke software resend of nested
interrupts by simply discarding the code that made sure that such
interrupts are retriggered using the parent interrupt.
Add back the corresponding code that adds the parent descriptor to the
resend list.

For transfers below 4K, let's use iATU since using eDMA for such small
transfers is inefficient.
This is mainly because setting up an eDMA transfer and waiting for
completion adds some latency. This latency is negligible for large
transfers but not for the smaller ones.
With using iATU, there is an increase in ~50Mbps throughput on both MHI
UL (Uplink) and DL (Downlink) channels.

Add support for Embedded DMA (eDMA) available in the DesignWare PCIe IP
to transfer the MHI buffers between the host and the endpoint. The eDMA
use helps achieve greater throughput as the transfers are offloaded from
CPUs.
For differentiating the iATU and eDMA APIs, the pci_epf_mhi_{read/write}
APIs are renamed to pci_epf_mhi_iatu_{read/write} and separate eDMA
specific APIs pci_epf_mhi_edma_{read/write} are introduced.
Platforms that require eDMA support can pass the MHI_EPF_USE_DMA flag
through pci_epf_mhi_ep_info.

Qualcomm PCIe Endpoint controllers have the in-built Embedded DMA (eDMA)
peripheral for offloading the data transfer between the PCIe bus and
memory.
Let's add support for it by enabling the eDMA IRQ in the driver. The
eDMA DMA Engine driver will handle the rest of the functionality.
Since the eDMA on Qualcomm platforms only uses a single IRQ for all
channels, use 1 for edma.nr_irqs.

This is a port of commit 379eb01c21795edb4c ("riscv: Ensure the value
of FP registers in the core dump file is up to date").
The values of FP/SIMD registers in the core dump file come from the
thread.fpu. However, kernel saves the FP/SIMD registers only before
scheduling out the process. If no process switch happens during the
exception handling, kernel will not have a chance to save the latest
values of FP/SIMD registers. So it may cause their values in the core
dump file incorrect. To solve this problem, force fpr_get()/simd_get()
to save the FP/SIMD registers into the thread.fpu if the target task
equals the current task.

Older PA-RISC machines have LEDs which show the disk- and LAN-activity.
The computation is done in software and takes quite some time, e.g. on a
J6500 this may take up to 60% time of one CPU if the machine is loaded
via network traffic.
Since most people don't care about the LEDs, start with LEDs disabled and
just show a CPU heartbeat LED. The disk and LAN LEDs can be turned on
manually via /proc/pdc/led.

Don't rely on the PCI memory for the devcmd opcode because we
read a 0xff value if the PCI bus is broken, which can cause us
to report a bogus dev_cmd opcode later.

Add a check that the wq exists before queuing up work for a
failed devcmd, as the PF is responsible for health and the VF
doesn't have a wq.

The VF doesn't need to send a reset command, and in a PCI reset
scenario it might not have a valid IO space to write to anyway.

Make sure the health reporter is set up before we use it in
our devlink health updates, especially since the VF doesn't
set up the health reporter.
