[PATCH 00/11] rtw89: prepare more shared code to work with 8852c

[PATCH 00/11] rtw89: prepare more shared code to work with 8852c

[Ping-Ke Shih]

This patchset contains MAC, BB and RF functions. The BB part changes
CFO (central frequency offset) tracking functions to be general. The MAC
part makes the function work on 8852c. Propose new V1 method to access new
design of RF register. 

As usual, this doesn't affect existing chip, and 8852C is built internally.

Chia-Yuan Li (3):
  rtw89: modify MAC enable functions
  rtw89: disable FW and H2C function if CPU disabled
  rtw89: 8852c: add mac_ctrl_path and mac_cfg_gnt APIs

Chung-Hsuan Hung (1):
  rtw89: 8852c: add read/write rf register function

Ping-Ke Shih (4):
  rtw89: add config_rf_reg_v1 to configure RF parameter tables
  rtw89: initialize preload window of D-MAC
  rtw89: extend mac tx_en bits from 16 to 32
  rtw89: implement stop and resume channels transmission v1

Yuan-Han Zhang (3):
  rtw89: modify dcfo_comp to share with chips
  rtw89: 8852c: add write/read crystal function in CFO tracking
  rtw89: 8852c: add setting of TB UL TX power offset

[PATCH 01/11] rtw89: modify dcfo_comp to share with chips

[Ping-Ke Shih]

From: Yuan-Han Zhang <yuanhan1020@realtek.com>

The dcfo_comp is digital CFO (central frequency offset) compensation.
Since the flow can be shared with all chips, add chip parameters to support
variant register address and format.

From: Yuan-Han Zhang <yuanhan1020@realtek.com>

The CFO tracking algorithm is the same, but control methods are different.
Set parameters via xtal serial interfaces (SI).

[PATCH 05/11] rtw89: add config_rf_reg_v1 to configure RF parameter tables

[Ping-Ke Shih]

The format of RF parameter is changed; it doesn't encode delay parameters
into table, but the delay coding becomes regular pair of register address
and value.

To help firmware to recover RF register settings, we need to download
these parameters to firmware. For v1 format, only download partial
parameters (ignore them with addr < 0x100).

[PATCH 07/11] rtw89: initialize preload window of D-MAC

[Ping-Ke Shih]

8852C add new hardware feature -- preload window, which is used to load
more data to D-MAC in advance, and then it can yield better performance.

This patch is to configure preload and reserved size for next window.

[PATCH 10/11] rtw89: extend mac tx_en bits from 16 to 32

[Ping-Ke Shih]

In order to support 8852C that uses 32 bits to control TX types.

This patch doesn't really use 32 bits tx_en yet, but next patch will
use it.

[PATCH 11/11] rtw89: implement stop and resume channels transmission v1

[Ping-Ke Shih]

These function is used to stop transmitting when we are going to switch
channels or do some RF calibration. Before these operations, we need to
stop channel transmission and backup setting into parameter tx_en. After
operations are done, resume transmitting by backup parameter tx_en.

Not really a fan of this style, wouldn't this be more readable:

val = 0;

if (gnt_cfg->band[0].gnt_bt)
       val |= B_AX_GNT_BT_RFC_S0_VAL | B_AX_GNT_BT_RX_VAL | B_AX_GNT_BT_TX_VAL;
else
       val |= B_AX_WL_ACT_VAL;

if (gnt_cfg->band[0].gnt_bt_sw_en)
       val |= B_AX_GNT_BT_RFC_S0_SWCTRL | B_AX_GNT_BT_RX_SWCTRL |
              B_AX_GNT_BT_TX_SWCTRL | B_AX_WL_ACT_SWCTRL;

For ": 0" cases the else branch is not needed.
