Subject: [U-Boot] [PATCH v3 0/5] usb: host: dwc2: use driver model for PHY and CLOCK
Date: Tue, 12 Nov 2019 10:42:09 +0100 [thread overview]
Message-ID: <20191112094214.12686-1-patrick.delaunay@st.com> (raw)
In this serie I update the DWC2 host driver to use the device tree
information and the associated PHY and CLOCK drivers when they are
available.
CI-Travis build is OK for all target after V3:
https://travis-ci.org/patrickdelaunay/u-boot/builds/609496187
In V2, I cause the warnings for some boards:
drivers/usb/host/built-in.o: In function `dwc2_usb_remove':
drivers/usb/host/dwc2.c:1441: undefined reference to `clk_disable_bulk'
I test this serie on stm32mp157c-ev1 board, with PHY and CLK
support
The U-CLASS are provided by:
- PHY by USBPHYC driver = ./drivers/phy/phy-stm32-usbphyc.c
- CLOCK by RCC clock driver = drivers/clk/clk_stm32mp1.c
- RESET by RCC reset driver = drivers/reset/stm32-reset.c
And I activate the configuration
+CONFIG_USB_DWC2=y
PS: it is not the default configuration to avoid conflict with gadget
driver
To solve a binding issue, I also deactivate the gadget support:
by default only one driver is bound to theusbotg_hs node with "snps,dwc2"
compatible, and today it is the device one (the first in the driver list).
I also need to deactivate hnp-srp support with:
&usbotg_hs {
/* need to disable ONLY for HOST support */
hnp-srp-disable;
};
WARNING: OTG with device or host support is not correctly handle by DWC2
driver (see example for dynamic OTG role in DWC3 driver).
The tests executed on the stm32mp157c-ev1 target:

Changes in v3:
- Add stub for clk_disable_bulk
Changes in v2:
- update dev_err
- update commit message
- change dev_err to dev_dbg for PHY function call
- treat dwc2_shutdown_phy error
- add clk_disable_bulk in dwc2_usb_remove
