Subject: [PATCH] rtl8xxxu: Implement rtl8188eu_init_phy_rf()
|
|
|
|
|
|
|
|
|
|
Include the table rtl8188eu_radioa_init_table derived from vendor
|
|
|
|
|
driver. The vendor table relies on a hack setting RF6052_REG_RCK1 +
|
|
|
|
|
RF6052_REG_RCK2 with delays. This workaround is open coded here
|
|
|
|
|
instead of modifying the table parsing code.
|
|
|
