When CONFIG_PM_SLEEP is disabled, the compiler warns about unused
functions:
drivers/net/phy/phy_device.c:273:12: error: unused function 'mdio_bus_phy_suspend' [-Werror,-Wunused-function]
static int mdio_bus_phy_suspend(struct device *dev)
drivers/net/phy/phy_device.c:293:12: error: unused function 'mdio_bus_phy_resume' [-Werror,-Wunused-function]
static int mdio_bus_phy_resume(struct device *dev)
The logic is intentional, so just mark these two as __maybe_unused
and remove the incorrect #ifdef.

The new GPIO support may be optional at runtime, but it requires
building against gpiolib:
ERROR: modpost: "gpiochip_get_data" [drivers/net/dsa/mt7530.ko]
undefined!
ERROR: modpost: "devm_gpiochip_add_data_with_key"

Add #ifdef to exclude GPIO support if GPIOLIB is not enabled.

When the ocelot driver code is in a library, the dsa tag
code cannot be built-in:
ld.lld: error: undefined symbol: ocelot_can_inject
>>> referenced by tag_ocelot_8021q.c
>>> dsa/tag_ocelot_8021q.o:(ocelot_xmit) in archive net/built-in.a
ld.lld: error: undefined symbol: ocelot_port_inject_frame
>>> referenced by tag_ocelot_8021q.c
>>> dsa/tag_ocelot_8021q.o:(ocelot_xmit) in archive net/built-in.a
Building the tag support only really makes sense for compile-testing
when the driver is available, so add a Kconfig dependency that prevents
the broken configuration while allowing COMPILE_TEST alternative when
MSCC_OCELOT_SWITCH_LIB is disabled entirely. This case is handled
through the #ifdef check in include/soc/mscc/ocelot.h.

ethernet: fixes for stmmac driver
Fixes for stmmac driver.
---
ChangeLogs:
V1->V2:
* subject prefix: ethernet: stmmac: -> net: stmmac:
* use dma_addr_t instead of unsigned int for physical address
* use cpu_to_le32()
V2->V3:
* fix the build issue pointed out by kbuild bot.
* add error handling for stmmac_reinit_rx_buffers() function.
V3->V4:
* remove patch (net: stmmac: remove redundant null check for ptp clock),
reviewer thinks it should target net-next.
V4->V5:
* use %pad format to print dma_addr_t.
* extend dwmac4_display_ring() to support all descriptor types.
* while() -> do-while()

During suspend/resume stress test, we found descriptor write back by DMA
could exhibit unusual behavior, e.g.:
003 [0xc4310030]: 0x0 0x40 0x0 0xb5010040
We can see that desc3 write back is 0xb5010040, it is still ownd by DMA,
so application would not recycle this buffer. It will trigger fatal bus
error when DMA try to use this descriptor again. To fix this issue, we
should re-init all rx buffers when mac resume back.

In current driver, buffer2 available only when hardware supports split
header. Wrongly set buffer2 valid in stmmac_rx_refill when refill buffer
address. You can see that desc3 is 0x81000000 after initialization, but
turn out to be 0x83000000 after refill.

Driver uses dma_alloc_coherent to allocate dma memory for descriptors,
dma_alloc_coherent will return both the virtual address and physical
address. AFAIK, virt_to_phys could not convert virtual address to
physical address, for which memory is allocated by dma_alloc_coherent.
dwmac4_display_ring() function is broken for various descriptor, it only
support normal descriptor(struct dma_desc) now, this patch also extends to
support all descriptor types.

stmmac_xmit() call stmmac_tx_timer_arm() at the end to modify tx timer to
do the transmission cleanup work. Imagine such a situation, stmmac enters
suspend immediately after tx timer modified, it's expire callback
stmmac_tx_clean() would not be invoked. This could affect BQL, since
netdev_tx_sent_queue() has been called, but netdev_tx_completed_queue()
have not been involved, as a result, dql_avail(&dev_queue->dql) finally
always return a negative value.
__dev_queue_xmit->__dev_xmit_skb->qdisc_run->__qdisc_run->qdisc_restart->dequeue_skb:
if ((q->flags & TCQ_F_ONETXQUEUE) &&
netif_xmit_frozen_or_stopped(txq)) // __QUEUE_STATE_STACK_XOFF is set
Net core will stop transmitting any more. Finillay, net watchdong would timeout.
To fix this issue, we should call netdev_tx_reset_queue() in stmmac_resume().

Following a similar reinstate for the KSZ9031.
Older kernels would use the genphy_soft_reset if the PHY did not implement
a .soft_reset.
Bluntly removing that default may expose a lot of situations where various
PHYs/board implementations won't recover on various changes.
Like with this implementation during a 4.9.x to 5.4.x LTS transition.
I think it's a good thing to remove unwanted soft resets but wonder if it
did open a can of worms?
Atleast this fixes one iMX6 FEC/RMII/8081 combo.

Currently, the psample netlink skb is allocated with a size that does
not account for the nested 'PSAMPLE_ATTR_TUNNEL' attribute and the
padding required for the 64-bit attribute 'PSAMPLE_TUNNEL_KEY_ATTR_ID'.
This can result in failure to add attributes to the netlink skb due
to insufficient tail room. The following error message is printed to
the kernel log: "Could not create psample log message".
Fix this by adjusting the allocation size to take into account the
nested attribute and the padding.

The AFBC decoder used in the Rockchip VOP assumes the use of the
YUV-like colourspace transform (YTR). YTR is lossless for RGB(A)
buffers, which covers the RGBA8 and RGB565 formats supported in
vop_convert_afbc_format. Use of YTR is signaled with the
AFBC_FORMAT_MOD_YTR modifier, which prior to this commit was missing. As
such, a producer would have to generate buffers that do not use YTR,
which the VOP would erroneously decode as YTR, leading to severe visual
corruption.
The upstream AFBC support was developed against a captured frame, which
failed to exercise modifier support. Prior to bring-up of AFBC in Mesa
(in the Panfrost driver), no open userspace respected modifier
reporting. As such, this change is not expected to affect broken
userspaces.
Tested on RK3399 with Panfrost and Weston.

__ibmvnic_reset() currently reads the adapter->state before getting the
rtnl and saves that state as the "target state" for the reset. If this
read occurs when adapter is in PROBED state, the target state would be
PROBED.
Just after the target state is saved, and before the actual reset process
is started (i.e before rtnl is acquired) if we get an ibmvnic_open() call
we would move the adapter to OPEN state.
But when the reset is processed (after ibmvnic_open()) drops the rtnl),
it will leave the adapter in PROBED state even though we already moved
it to OPEN.
To fix this, use the RTNL to improve serialization when reading/updating
the adapter state. i.e determine the target state of a reset only after
getting the RTNL. And if a reset is in progress during an open, simply
set the target state of the adapter and let the reset code finish the
open (like we currently do if failover is pending).
One twist to this serialization is if the adapter state changes when we
drop the RTNL to update the link state. Account for this by checking if
there was an intervening open and update the target state for the reset
accordingly (see new comments in the code). Note that only the reset
functions and ibmvnic_open() can set the adapter to OPEN state and this
must happen under rtnl.
