Subject: [PATCH 0/6] phy: usb: add support for STM32 usbphyc
Date: Thu, 20 Feb 2020 11:01:05 +0100 [thread overview]
Message-ID: <20200220100109.18147-1-a.fatoum@pengutronix.de> (raw)
This is only USB PHY support. Changes to the DWC2 (OTG) and/or OHCI
(Host) are still needed to make USB on the MP1 work.
I haven't yet groked the relation between generic phy and usb phy
frameworks, but the code is a straight port from Linux and it seems to
work[1], so let's upstream it now to make collaboration easier.
[1]: clock the EHCI and power on the PHY and 20% of the time, the bus
can be enumerated completely. Still needs further debugging,
but it's unlikely that the PHY driver is at fault.
Cheers,
Ahmad Fatoum (6):
regulator: import Linux regulator_bulk API
phy: remove unused init_data parameter
phy: populate existing ->pwr member with phy-supply
phy: introduce phy_get_by_index
regulator: port over Linux stm32 PWR regulator driver
phy: port over Linux stm32 usbphyc driver
