[PATCH v6 6/6] wifi: rtlwifi: Adjust rtl8192d-common for USB

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A few of the shared functions need small changes for the USB driver:
 - firmware loading
 - efuse reading
 - rate mask updating
 - rf register reading
 - initial gain for scanning

Also, add a few macros to wifi.h and initialise rtlhal.interfaceindex
for USB devices.

Signed-off-by: Bitterblue Smith <rtl8821cerfe2@xxxxxxxxx>
---
v6:
 - Remove the things added to struct rtl_priv in v4 of this patch.
   They will be added in a later patch.

v5:
 - No change.

v4:
 - Update the commit message.
 - Move _rtl92d_pci_lock and _rtl92d_pci_unlock to phy_common.h to
   silence a checkpatch warning.
 - Move rate_mask declaration higher (sorted by length).
 - Add some bit definitions to reg.h.
 - Add to struct rtl_priv the things shared by the two USB interfaces
   of a dual MAC RTL8192DU:
	u32 *curveindex_2g;
	u32 *curveindex_5g;
	struct mutex *mutex_for_power_on_off;
	struct mutex *mutex_for_hw_init;

v3:
 - Silence sparse warnings about locks in phy_common.c by using helper
   functions _rtl92d_pci_lock() and _rtl92d_pci_unlock().

v2:
 - Delete the macro IS_NORMAL_CHIP. It wasn't actually used.
 - Add RTL_USB_DELAY_FACTOR macro.
 - Use FEN_CPUEN macro.
 - Make params_pci and params_usb arrays static const, and make
   rtl_get_hwinfo() take a const pointer.
 - Put the rate mask, macid, etc. in a struct in
   rtl92de_update_hal_rate_mask().
 - Use sizeof(rtlpriv->rate_mask) in memcpy instead of hardcoded 5.
 - Rename temp variable to phy_ctrl.
 - Define _TXDMA_*_MAP and _HPQ, _LPQ, _PUBQ macros using GENMASK and
   remove the leading underscore.
 - Delete _NPQ macro because it's not very useful.
