On the AM62P platform we have no single 1:1 relation regarding index
of GPIO and pin controller. The GPIOs and pin controller registers
have mapping and holes in the map. These have been extracted from the
AM62P data sheet.
MCU pinctrl definition is shared as it is common between AM62P and
J722S, but that is not the case for main domain.

Introduce a GPIO mux mode macro for easier readability. All K3 devices
use mux mode 7 to switch to GPIO mux and this allows the gpio-ranges to
be defined for pinctrl-single clearly.

The WKUP system controller address region contains an eFuse block with
MAC addresses to be used by the Ethernet controller. The property
“ti,syscon-efuse” contains a phandle to a syscon region and an offset
into this region where the MAC addresses can be found. Currently
"ti,syscon-efuse" points to the entire system controller address space
node with an offset to the eFuse IP address.
Instead add a cpsw-mac-efuse node to describe the exact eFuse area. Then
point the Ethernet controller directly to this region, no offset needed.

Expansion port on the am62-lp-sk EVM.
The following pins are shared between McASP1 and GPMC-NAND so
both cannot work simultaneously.

P21 MCASP1_AFSX GPMC0_WAIT0
K17 MCASP1_ACLKX GPMC0_BE0N_CLE
K20 MCASP1_AXR2 GPMC0_ADVN_ALE
The factory default sets the pins for McASP1 use. (i.e.

For NAND use, RA1 has to be removed and RA4 must be
installed.

for all am6xx-phycore-som boards.
The EEPROM on am6xx-phycore-soms contains information about the

has an ospi nor, but if qspi nor is populated, the EEPROM will
indicate that change and we can use this overlay to cleanly change to

In current configuration, nau8822 codec on development carrier board
provides distorted audio output. This happens due to reference clock
is fixed to 25MHz and no PLL is enabled. Following is the calculation
of deviation error for different frequencies:
44100Hz:
fs = 256 (fixed)
prescaler = 2
target frequency = 44100 * 256 * 2 = 22579200
deviation = 22579200 vs 25000000 = 9.6832%
48000Hz:
fs = 256 (fixed)
prescaler = 2
target frequency = 48000 * 256 * 2 = 24576000
deviation = 24576000 vs 25000000 = 1.696%
Enabling nau822 PLL via providing mclk-fs property to simple-audio-card
configures clocks properly, but also adjusts audio reference clock
(mclk), which in case of TI AM62 should be avoided, as it only
supports 25MHz output [1][2].
This change enables PLL on nau8822 by providing mclk-fs, and moves
away audio reference clock from DAI configuration, which prevents
simple-audio-card to adjust it before every playback [3].

reclaim
There is a potential parallel list adding for retrying in
btrfs_reclaim_bgs_work and adding to the unused list. Since the block
group is removed from the reclaim list and it is on a relocation work,
it can be added into the unused list in parallel. When that happens,
adding it to the reclaim list will corrupt the list head and trigger
list corruption like below.
Fix it by taking fs_info->unused_bgs_lock.

There is a similar retry_list code in btrfs_delete_unused_bgs(), but it is
safe, AFAICS. Since the block group was in the unused list, the used bytes
should be 0 when it was added to the unused list. Then, it checks
block_group->{used,reserved,pinned} are still 0 under the
block_group->lock. So, they should be still eligible for the unused list,
not the reclaim list.
The reason it is safe there it's because because we're holding
space_info->groups_sem in write mode.
That means no other task can allocate from the block group, so while we
are at deleted_unused_bgs() it's not possible for other tasks to
allocate and deallocate extents from the block group, so it can't be
added to the unused list or the reclaim list by anyone else.
The bug can be reproduced by btrfs/166 after a few rounds. In practice
this can be hit when relocation cannot find more chunk space and ends
with ENOSPC.

The change adding caching around the request allocated and freed for
data messages changed a kmem_cache_free() to a kfree(), which isn't
correct as the request came from slab in the first place. Fix that up
and use the right freeing function if the cache is already at its limit.
Note that the current mixing of kmem_cache_alloc and kfree is fine, but
consistent alloc/free functions should be used as it's otherwise somewhat
confusing.

We used bpf_prog_pack to aggregate bpf programs into huge page to
relieve the iTLB pressure on the system. We can apply it to bpf
trampoline, as Song had been implemented it in core and x86 [0]. This
patch is going to use bpf_prog_pack to RV64 bpf trampoline. Since Song
and Puranjay have done a lot of work for bpf_prog_pack on RV64,
implementing this function will be easy.

We get the size of the trampoline image during the dry run phase and
allocate memory based on that size. The allocated image will then be
populated with instructions during the real patch phase. But after
commit 26ef208c209a ("bpf: Use arch_bpf_trampoline_size"), the `im`
argument is inconsistent in the dry run and real patch phase. This may
cause emit_imm in RV64 to generate a different number of instructions
when generating the 'im' address, potentially causing out-of-bounds
issues. Let's emit the maximum number of instructions for the "im"
address during dry run to fix this problem.

For trampoline using bpf_prog_pack, we need to generate a rw_image
buffer with size of (image_end - image). For regular trampoline, we use
the precise image size generated by arch_bpf_trampoline_size to allocate
rw_image. But for struct_ops trampoline, we allocate rw_image directly
using close to PAGE_SIZE size. We do not need to allocate for that much,
as the patch size is usually much smaller than PAGE_SIZE. Let's use
precise image size for it too.

This adds a small internal mapping table so that a new bpf (xdp) kfunc
can perform lookups in a flowtable.
As-is, xdp program has access to the device pointer, but no way to do a
lookup in a flowtable -- there is no way to obtain the needed struct
without questionable stunts.
This allows to obtain an nf_flowtable pointer given a net_device
structure.
In order to keep backward compatibility, the infrastructure allows the
user to add a given device to multiple flowtables, but it will always
return the first added mapping performing the lookup since it assumes
the right configuration is 1:1 mapping between flowtables and net_devices.

i.MX95 has a DDR PMU which is almostly same as i.MX93, it now supports
read beat and write beat filter capabilities. This will add support for
i.MX95 and enhance the driver to support specific filter handling for it.
Usage:
For read beat:
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt2,axi_mask=ID_MASK,axi_id=ID/
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt1,axi_mask=ID_MASK,axi_id=ID/
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt0,axi_mask=ID_MASK,axi_id=ID/
eg: For edma2: perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_rd_beat_filt0,axi_mask=0x00f,axi_id=0x00c/
For write beat:
~# perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_wr_beat_filt,axi_mask=ID_MASK,axi_id=ID/
eg: For edma2: perf stat -a -I 1000 -e imx9_ddr0/eddrtq_pm_wr_beat_filt,axi_mask=0x00f,axi_id=0x00c/

In current design, the user of perf app needs to input counter ID to count
events. However, this is not user-friendly since the user needs to lookup
the map table to find the counter. Instead of letting the user to input
the counter, let this driver to manage the counters in this patch.
This will be implemented by:
1. allocate counter 0 for cycle event.
2. find unused counter from 1-10 for reference events.
3. allocate specific counter for counter-specific events.
In this patch, counter attr will be kept for back-compatible but all the
value passed down by counter=<n> will be ignored. To mark counter-specific
events, counter ID will be encoded into perf_pmu_events_attr.id.
