Subject: [PATCH] phy: phy-brcm-usb: fixup BCM4908 support
|
|
MIME-Version: 1.0

|
Just like every other family BCM4908 should get its own enum value. That
|
|
is required to properly handle it in chipset conditional code.
|
|
|
|
The real change is excluding BCM4908 from the PLL reprogramming code
|
|
(see brcmusb_usb3_pll_54mhz()). I'm not sure what's the BCM4908
|
|
reference clock frequency but:
|
|
1. BCM4908 custom driver from Broadcom's SDK doesn't reprogram PLL
|
|
2. Doing that in Linux driver stopped PHY handling some USB 3.0 devices
|
|
|
|
This change makes USB 3.0 PHY recognize e.g.:
|
|
1. 04e8:6860 - Samsung Electronics Co., Ltd Galaxy series, misc. (MTP mode)
|
|
2. 1058:259f - Western Digital My Passport 259F
|
|
|
|
Broadcom's STB SoCs come with a set of SUN_TOP_CTRL_* registers that
|
|
allow reading chip family and product ids. Such a block & register is
|
|
missing on BCM4908 so this commit introduces "compatible" string
|
|
specific binding.
|
|
