book3s/32 has two main families:
- CPU with 603 cores that don't have HASH PTE table and
perform SW TLB loading.
- Other CPUs based on 604+ cores that have HASH PTE table.
This leads to some complex logic and additionnal code to
support both. This makes sense for distribution kernels
that aim at
flush_range() handle both the MMU_FTR_HPTE_TABLE case and
the other case.
The non MMU_FTR_HPTE_TABLE case is trivial as it is only a call
to _tlbie()/_tlbia() which is not worth a dedicated function.
Make flush_range() a hash specific and call it from tlbflush.h based
on
As 601 is gone, CONFIG_PPC_BOO3S_6xx and CONFIG_PPC_BOOK3S_32

The struct irq_info of Xen's event handling is used only for two
evtchn_ops functions outside of events_base.c. Those two functions
can easily be switched to avoid that usage.
This allows to make struct irq_info and its related access functions
private to events_base.c.

Do some cleanups in Xen event handling code.

xen: remove no longer used functions
xen/events: make struct irq_info private to events_base.c
xen/events: only register debug interrupt for 2-level events
xen/events: unmask a fifo event channel only if it was masked
Unmasking an event channel with fifo events channels being used can
require a hypercall to be made, so try to avoid that by checking
whether the event channel was really masked.

The ADIN1300/ADIN1200 support cable diagnostics using TDR.
The cable fault detection is automatically run on all four pairs looking at
all combinations of pair faults by first putting the PHY in standby (clear
the LINK_EN bit, PHY_CTRL_3 register, Address 0x0017) and then enabling the
diagnostic

When offset is not 4 bytes aligned, directly shift righty by 2 bits
will cause reading out wrong data. Since imx ocotp only supports
4 bytes reading once, we need handle offset is not 4 bytes aligned
and enlarge the bytes to 4 bytes aligned. After reading finished,
copy the needed

changes v3:
- can-controller.yaml: add "additionalProperties: true"
- fsl,flexcan.yaml: remove maxItems and not needed type definition
changes v2:
- add can-controller.yaml for common patterns
- use phandle-array instead of uint32-array
- Drop the outer 'items' in fsl,stop-mode
- use can@ instead
For now we have only node name as common rule for all CAN controllers

DMA-based transfer will be enabled if data length is larger than FIFO size
(64 bytes for A64). This greatly reduce number of interrupts for
transferring data.
For smaller data size PIO mode will be used. In PIO mode whole buffer will
be loaded into FIFO.

In the SD specification v7.10 the SD express card has been added. This new
type of removable SD card, can be managed via a PCIe/NVMe based interface,
while also allowing backwards compatibility towards the legacy SD
interface.

The ether_setup function adds the IFF_TX_SKB_SHARING flag to the
device. This flag indicates that it is safe to transmit shared skbs to
the device.
However, this is not true for many Ethernet devices. Many Ethernet
drivers would call skb_pad or skb_padto on the transmission path,
which modify the
