Subject: [PATCH] r8152: replace several functions about phy patch
|
|
request
|
|
|
|
commit a08c0d309d8c078d22717d815cf9853f6f2c07bd upstream.
|
|
|
|
Replace r8153_patch_request() with rtl_phy_patch_request().
|
|
Replace r8153_pre_ram_code() with rtl_pre_ram_code().
|
|
Replace r8153_post_ram_code() with rtl_post_ram_code().
|
|
Add rtl_patch_key_set().
|
|
|
|
The new functions have an additional parameter. It is used to wait
|
|
the patch request command finished. When the PHY is resumed from
|
|
the state of power cut, the PHY is at a safe mode and the
|
|
OCP_PHY_PATCH_STAT wouldn't be updated. For this situation, it is
|
|
safe to set patch request command without waiting OCP_PHY_PATCH_STAT.
