[PATCH v3 0/3] ath11k: Add IPQ6018 support

[Anilkumar Kolli]

IPQ6018 has a 5G radio and 2G radio with 2x2
and shares IPQ8074 configuration.

Tested on: IPQ6018 WLAN.HK.2.2-02134-QCAHKSWPL_SILICONZ-1
Tested on: IPQ8074 WLAN.HK.2.4.0.1-00009-QCAHKSWPL_SILICONZ-1

  ath11k: add IPQ6018 support

V2:
 - Added devicetree reviewers 
V3:
 - addressed dt bindinds comments
 - Reworked on Kalles patches
 - copied ce svc configs to hw_params

I think you misunderstood my point about this, the point wasn't to
copy the svc map to hw_params, but define it in hw_params:

+       {
+               .hw_rev = ATH11K_HW_IPQ6018,
+               .name = "ipq6018 hw1.0",
+               .fw = {
+                       .dir = "IPQ6018/hw1.0",
+                       .board_size = 256 * 1024,
+                       .cal_size = 256 * 1024,
+               },
+               .max_radios = 2,
+               .bdf_addr = 0x4ABC0000,
+               .hw_ops = &ipq6018_ops,
+               .svc_to_ce_map_len =
ARRAY_SIZE(target_service_to_ce_map_wlan_ipq6018,
+               .svc_to_ce_map = target_service_to_ce_map_wlan_ipq6018,
+       },

That completely eliminates special case code based on the hardware ID
in the driver.

The static array of structures target_service_to_ce_map_wlan_ipq6018[] 
is defined in ahb.c and hw_params are initialised in core.c, this will 
not work. no?

My understanding, and please correct me if I'm wrong, is that the
service map is a property of the hardware. So why not define all the
hardware properties in one place?

You could either move the hardware definitions and service maps to a
new file (maybe ahb_conf.c), move those maps to ahb.c or just add them
to some header file so ahb.c can reference them.

Just need:

enum:
  - qcom,ipq8074-wifi
  - qcom,ipq6018-wifi

You could move the map arrays to hw.c, as an example see how
ath11k_hw_ring_mask_ipq8074 is implemented. That way we don't need any
new hw_rev checks.
