Add a new USB Phy driver for Broadcom STB SoCs. This driver
supports Broadcom STB ARM SoCs. This driver in
combination with the Broadcom STB ohci, ehci and xhci
drivers will enable USB1.1, USB2.0 and USB3.0 support.
This Phy driver also supports the Broadcom BDC gadget
driver.
Changes since v3:
- Removed MIPS support because there is such a small
amount of code that is common to both ARM and MIPS.
I'll create a separate MIPS driver in the future.
- Have the Kconfig selection for this driver also select
"CONFIG_SOC_BRCMSTB" which contains needed functions.
- Change device tree properties to use "brcm,has_xhci" and
"brcm,has_eohci" to determine if the phy contains
a xhci phy, and e/ohci phy or both.
- Change the phy xlate routine to return an error instead
of NULL for a requested phy that doesn't exist.
- Moved some probe functionality into it's own funtion to
simplify the many "if (has_xhci)" statements.
Changes since v2:
- Fix kbuild errors by changing Kconfig so the driver
only builds for ARCH_BRCMSTB || BMIPS_GENERIC systems
Changes since v1:
- Rebased to next
- Add Kconfig entry to build the driver
- Commented all delays
- Split out sysfs functionality in separate patch
- Removed parsing of old obselete device tree properties
- Changed device property "device" to "dr_mode" using
standard values "host" and "peripheral" along with new
values "drd" and "typec-pd"
- Add ability to handle the standard PHY_TYPE_USB2 and
PHY_TYPE_USB3 arguments passed in by phy consumers.
- Moved phy_provider_register() to end of probe routine
