The commit 127ea8d0b068 ("wifi: rtw89: fix typo "frome" -> "from" in rx_freq_frome_ie")
change the struct field to correct the typo, but miss to fix this for
RTL8922D because it is submitting at the same time.
As RTL8922D is not enabled yet, this build error doesn't appear.
Fix it accordingly.

Improve user experience while using interactive applications.
Adjust power saving decisions under different scenarios.
Minimize latency for delay-sensitive connections by exiting
power-save on packet bursts and maintain active until a period
of inactivity is reached. For connections that are not that
sensitive to delays, keep the current aggressive power save logic.

This helps avoid scan-triggered off-channel activity during
latency-sensitive scenarios.
Add RTW89_DM_HW_SCAN to the disabled_dm bitmap via debugfs and
check it in the hw_scan path. When set, the driver rejects hw_scan
requests and returns -EBUSY.

This helps avoid excessive bus traffic and I/O overhead on
slower HCIs (e.g., USB, SDIO) caused by frequent power state
transitions.
Add RTW89_DM_INACTIVE_PS to the disabled_dm bitmap via debugfs and
check it in the rtw89_enter_ips path. When set, the driver skips
entering inactive power save and returns immediately.

PD (Packet Detection) threshold is a key parameter in the DIG
(Dynamic Initial Gain) algorithm that determines the sensitivity
of packet detection. Current implementation only supports dynamic
PD adjustment based on environment. This patch adds support for
static PD threshold via debugfs allowing users to set a fixed PD
value for testing or specific scenarios.

A kernel soft lockup was observed during Wi-Fi scanning on the 6GHz band.
The CPU becomes stuck in rtw89_hw_scan_add_chan_ax for over 20 seconds,
leading to a system panic.
RIP points to 0f b6 c3 (movzbl %bl, %eax), which zero-extends
the low 8 bits of RBX into RAX.
RBX (the counter i) has reached a huge value: 0x137466a1.

From: Chia-Yuan Li <leo.li@realtek.com>
Offload register write operations to the firmware to improve IO efficiency.
Instead of the host performing direct bus access for every register, the
operations are now encapsulated into firmware commands.
This implementation allows the host to aggregate multiple register write
actions into a single command buffer. By batching these operations, we
reduce the number of individual transactions on the bus and minimize
per-transfer overhead, leading to faster overall IO performance.
Add a support_fw_cmd_ofld field to the chip_info structure to control
whether firmware-offloaded batch writes are enabled. Enable it by
default for RTL8832CU.

From: Chia-Yuan Li <leo.li@realtek.com>
During the initialization of DMAC and CMAC, the driver performs a
large number of consecutive register writes. Sending these I/O
requests individually over the host interface introduces significant
latency and delays the device bring-up process.
Optimize the initialization flow by wrapping the register write
sequences in mac.c and mac_be.c with rtw89_io_pack() and
rtw89_io_unpack(). This batches the operations and offloads them
to the firmware via H2C commands, which significantly accelerates
the overall initialization time.

From: Eric Huang <echuang@realtek.com>
Use firmware offload to perform batch register writes for PHY and RF.
This reduces I/O operations, improves bus transfer efficiency, and
decreases hardware initialization time.
Performance improvement on USB 2.0 HCI:
- rtw89_phy_init_bb_reg: 61 ms -> 5 ms
- rtw89_phy_init_rf_reg: 587 ms -> 106 ms
Use offload-aware delay functions (do_udelay and do_mdelay) for the
delay calls in rtw89_phy_init_reg, rtw89_phy_config_rf_reg, and
rtw89_phy_config_rf_reg_v1 to ensure compatibility with batch register
writes.

The original flow checks the scan offload C2H event done ack to increase
the scan sequence. However, the scan offload response C2H event may be
received earlier than the scan offload C2H event done ack, which causes
these C2H event to be dropped by rtw89_fw_c2h_purge_obsoleted_scan_events()
check because the scan sequence of the scan offload response C2H event
is less than the scan offload C2H event done ack. Therefore, checking
the scan offload C2H event recv ack instead of C2H event done ack to fix
this issue.

From: Chih-Kang Chang <gary.chang@realtek.com>
The PD (Packet Detection) lower bound is set after the STA interface
connects. When the P2P interface attempts to find peers, it enters
the remain-on-channel flow to listen for probe requests. However, if
the RSSI of the connected AP is too high, the P2P interface fails to
receive it. To resolve this, suspend the DIG during the
remain-on-channel period.

From: Zong-Zhe Yang <kevin_yang@realtek.com>
The original helper can only queries target channel, but cannot determine
current role's status, e.g. is it MLD or not. These things should be a set.
Adding more and more helpers to query them individually without synchronous
doesn't seem right. Introduce a new helper to query current channel set and
role status.
Besides, when single channel, e.g. MLO_2_PLUS_0_1RF and MLO_0_PLUS_2_1RF,
the target channel pointer will be duplicated to fill the returned channel
set. So, some callers can save trivial things for these cases. The returned
channels will be non-NULL, so callers don't need trivial NULL check either.

From: Zong-Zhe Yang <kevin_yang@realtek.com>
RF calibration (RFK) will record the results in HW RFK tables. SW can
select and configure the target HW RFK table to reuse the RFK result
on the target channel. Though the above can work as before, when MLD
runs eMLSR mode, a faster switching between links than SW is needed.
So, introduce a new working flow for MLD. With the new settings, HW
can easily switch RFK results between links during eMLSR mode.
