[PATCH 00/16] rtw89: refine PCI and MAC codes into function with attributes

[PATCH 00/16] rtw89: refine PCI and MAC codes into function with attributes

[Ping-Ke Shih]

The existing PCI and MAC codes are only used by 8852AE, so many settings are
put in single function. To be clear, move the settings into an individual
function according to its functionality. Since functions will be shared
with chips, add attributes to make it possible to use common functions.

Also, update the settings to the latest version of our internal code.

This patchset is based on                                                       
 "rtw89: add firmware reset and dump firmware memory and backtrace" and
 "rtw89: update TX power table and 6G, refine IGI, and add TX/RX descriptors V1"
But no actual function dependency.

[PATCH 01/16] rtw89: pci: add register definition to rtw89_pci_info to generalize pci code

[Ping-Ke Shih]

The PCI code of 8852AE and 8852CE are different, but the flow and register
names are similar. To reuse the code, add a struct to define register or
value accordingly. We also use chip id to control the slightly different
flow.

[PATCH 03/16] rtw89: pci: refine pci pre_init function

[Ping-Ke Shih]

From: Chia-Yuan Li <leo.li@realtek.com>

The pre_init is used to initialize partial PCI function during PCI probe.
It doesn't need to initialize all functions, so probe can be faster.

The merge window is now open which means wireless-next is closed. I
don't mind people submitting few -next patches during the merge window,
but there's a limit for that. Currently I see 39 rtw89 patches in
patchwork, that's just too much. So please try to limit the number of
patches you submit during the merge window.

Usually wireless-next opens few days after -rc1 is released, but there's
no fixed schedule.

Got it. I'll stop submitting before queued patches get reviewed. 
If this patchset is inconvenient to you, please drop it.
