Currently, Ath12k driver only supports WiFi devices that are based on
PCI bus. New Ath12k device IPQ5332 is based on AHB bus. Hence, add
Ath12k AHB support for IPQ5332.

IPQ5332 is IEEE802.11be 2 GHz 2x2 Wifi device. To bring-up IPQ5332
device:
- Add hardware parameters for IPQ5332.
- CE register address space in IPQ5332 is separate from WCSS register
  space. Hence, add logic to remap CE register address.
- Add support for fixed QMI firmware memory for IPQ5332.
- Support userPD handling for WCSS secure PIL driver to enable ath12k
  AHB support.

v4:
- Missed to include some review list in v3. Hence sending v4 with
  all review list as per - scripts/get_maintainers.pl

v3: https://lore.kernel.org/all/20241209165644.1680167-1-quic_rajkbhag@quicinc.com/
- DT binding: clock name changed from gcc_xo_clk to xo.
- DT binding: Upper constraint added for memory-region property.
- DT binding: The description for "qcom,rproc" phandle updated to represent
  the hardware aspect.
- DT binding: Added property qcom,ath12k-calibration-variant.
- Squashed patch[2/22] to patch[8/22] of v2 into a single patch.
- Patch reordering is done.
- The hardware parameter "m3_fw_support" renamed to "needs_m3_fw".
- CMEM remap and CMEM register handling are dropped. CMEM registers are
  accessed within WCSS register space (ab->mem).
- The devm APIs are used for interrupts handling.
- Logic updated in ath12k_ahb_map_service_to_pipe().
- Dependency path series from other subsystem are dropped.

v2: https://lore.kernel.org/all/20241015182637.955753-1-quic_rajkbhag@quicinc.com/
- "qcom,board_id" property is dropped. This is not the direct dependency
  for Ath12k AHB support, hence it can be taken up separately.
- "qcom,bdf-addr" property is dropped in device-tree and moved to ath12k
  driver.
- Currently we have only one compatible enum (qcom,ipq5332-wifi), hence
  conditional if() check for defining the binding is removed.
- "reserved-memory" node is dropped from example DTS.
- "status" property is dropped in wifi node of example DTS.
- Integrated the “Support userPD handling for WCSS secure PIL driver”
  patch series with the Ath12k AHB bring-up patch.
- Removed the RFC tag as all dependency patch series are now compilable.

In the current ath12k implementation, the CE addresses
CE_HOST_IE_ADDRESS and CE_HOST_IE_2_ADDRESS are incorrect. These
values were inherited from ath11k, but ath12k does not currently use
them.

However, the Ath12k AHB support relies on these addresses. Therefore,
corrects the CE addresses for ath12k.

From: P Praneesh <quic_ppranees@quicinc.com>

IPQ5332 device have different register address values for the below
registers:

HAL_TCL1_RING_BASE_LSB
HAL_TCL1_RING_BASE_MSB
HAL_TCL2_RING_BASE_LSB

HAL_SEQ_WCSS_UMAC_CE0_SRC_REG
HAL_SEQ_WCSS_UMAC_CE0_DST_REG
HAL_SEQ_WCSS_UMAC_CE1_SRC_REG
HAL_SEQ_WCSS_UMAC_CE1_DST_REG

Hence, refactor ath12k_hw_regs structure to accommodate these changes
in IPQ5332.

From: Balamurugan S <quic_bselvara@quicinc.com>

Add ath12k_hw_params for new ath12k AHB based WiFi device IPQ5332.
Some hardware parameters like hw_ops, wmi_init & hal_ops are same
between IPQ5332 and QCN9274, hence use these same parameters for
IPQ5332.

Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00210-QCAHKSWPL_SILICONZ-1

From: Balamurugan S <quic_bselvara@quicinc.com>

Current ath12k devices, QCN9274 and WCN7850, supports m3.bin firmware
download through ath12k driver. The new ath12k AHB based device
IPQ5332 supports m3 firmware download through remoteproc driver.

Hence, add new parameter (needs_m3_fw) in ath12k_hw_params to avoid
m3 firmware download in IPQ5332.

Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00210-QCAHKSWPL_SILICONZ-1

From: Balamurugan S <quic_bselvara@quicinc.com>

For IPQ5332 CE register space is moved out of WCSS region and the
space is not contiguous. Hence, add hardware params (ce_ie_addr &
ce_remap) for IPQ5332. These parameters would be used by Ath12k
AHB driver (in subsequent patches) to remap the CE registers to a
new space for accessing them.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00210-QCAHKSWPL_SILICONZ-1

IPQ5332 firmware supports only fixed QMI firmware memory.

Hence, add support to read reserved fixed memory region from
device-tree and provide the reserved memory segments for
firmware to use during QMI firmware memory request.

Note that the ability to set the fixed memory will be introduced in
a subsequent patch. Currently, the flag remains unset by default,
ensuring that existing chipsets are unaffected.

Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00210-QCAHKSWPL_SILICONZ-1

Q6 processor acts as rootPD, other hardware like IPQ5332 which are
attached to Q6 act as userPDs. WCSS driver handles loading and booting
of rootPD, while the ath12k driver boots the userPD.
Get the rproc handle from the DTS entry and boot the rootPD if it
is not already powered on. Register to the rproc notifier to monitor
the rproc state, this allows ath12k driver to know power up/down
sequence of the rootPD. Power up the rootPD and wait for a power-up
notification from the notifier callback before powering up the userPDs.

From: Sowmiya Sree Elavalagan <quic_ssreeela@quicinc.com>

Q6 and ath12k driver communicates using SMEM and IRQs. Spawn interrupt
is triggered once the userPD thread is spawned. Ready interrupts denotes
userPD is completely powered up and ready. Stop-ack is to acknowledge
the ath12k driver that userPD is stopped. Ath12k driver needs to set spawn
bit in SMEM to instruct Q6 to spawn a userPD. Similarly stop bit is
set when userPD needs to be stopped.

From: Sowmiya Sree Elavalagan <quic_ssreeela@quicinc.com>

UserPD firmware image is loaded and booted by ath12k driver. Get the userPD
memory region from DTS and load the firmware for userPD from pre-defined
path into io-remapped address of this region. Authenticate this image
using pasid which is a peripheral ID. Set the spawn bit to instruct Q6
to spawn userPD thread. Wait for userPD to spawn which is indicated by
spawn interrupt. Ready interrupt is triggered once the userPD is powered
up completely.

Set the stop bit in SMEM to power down the userPD. Wait for stop-ack IRQ
to indicate power down completion. Release the userPD firmware using its
peripheral ID.

From: Balamurugan S <quic_bselvara@quicinc.com>

Currently only PCI devices are supported in Ath12k driver. Refactor
Ath12k module_init and module_exit to include Ath12k AHB support.

Add Ath12k AHB support in Kconfig with dependency on Remoteproc
driver. Ath12k AHB support relies on remoteproc driver for firmware
download, power up/down etc.

NAK

That's neither correct name nor documented in the bindings. You created
now undocumented ABI. Even with incorrect name. :/

You don't use this header.

This goes to driver struct declaration. It is really unusual to see it

You already print once in ath12k_ahb_get_hw_rev() and none of these can
happen. No need to print impossible conditions at all. No need to print
impossible things twice.

NAK. Incorrect name, not conforming to coding style. Undocumented ABI.

Drop all calls to of_find_node_by_name() or any other stuff like this.

You are not supposed to read phandles as numbers but use proper phandle
parsing API. See of.h, e.g. of_parse_phandle.

This is supposed to be dev_err_probe. Lack of handling deferred probes
and resulting dmesg flood is all over your code. You need to start
supporting defer.

Don't bug users with success messages. Your driver is supposed to be

The amount of undocumented ABI you add here, points to the problem that
either your drivers don't work or your drivers would never work with
upstream. Why? Because either you would have wrong DTS or drivers not
matching DTS, thus not working.

Please point us to your upstream DTS implementing (and working 100%)
this ABI, so we can review that you do not sneak more broken or
undocumented things. I will NAK also future submissions without above,
because I believe you usptream something which will not work.

Krzysztof

I dug a bit and I found your earlier v2:
https://lore.kernel.org/all/20241015182637.955753-3-quic_rajkbhag@quicinc.com/

which confirms:
1. DTS not following coding style, so not possible to accept
2. Driver relying on that exact DTS, so not really working.

Please post in separate series updated DTS, after fixing all the issues
pointed out by DTS coding style.

Best regards,
Krzysztof

Most of the Device Tree related concern in this series are from the
undocumented ABIs and wrong naming (use of '_' instead of '-'):
"m3_dump" and "mlo_global_mem_0".

To address the undocumented ABIs, "memory-region" and "memory-region-names"
should be used to reference all the reserved memory required. This should
include "m3_dump" and "mlo_global_mem_0" memory region.

If the above approach valid to address undocumented ABIs?

You already use them, so this code here and explanation is confusing.

Dunno. Change all node names, run dtbs_check. Do you see errors? Now run
your driver. Does it work correctly? If yes, then ABI seems documented.
If not, ABI is not documented.
