Hello, Here's v2 of the Aspeed pinctrl USB patches. It addresses the minor feedback on the original series[1], amounting to commit message changes for the bindings patches. [1] https://lkml.org/lkml/2017/6/26/854 Please review!

Implement the AST2400 USB functions as described by the devicetree
bindings. Three ports are fully documented in the datasheet and exposed
through the bindings and pinctrl, though there are remnants of
documentation for a fourth port muxed with GPIO pins GPIOQ6 and GPIOQ7.
The implementation is updated to reflect this but the function and
group are not exposed.
Disregarding the mostly undocumented fourth port, the USB functions are
an outlier with respect to the rest of the muxed functionality on the
AST2400 as GPIO is not supported on these pins.

Implement the AST2500 USB functions as described by the devicetree
bindings. The AST2500 exposes five USB controllers through two USB
ports. Similar to the AST2400, the pins exposing USB are outliers with
respect to the rest of the pinmux as they not capable of GPIO.

The AST2400 contains several USB controllers: * USB 1.1 Host Controller * USB 2.0 Host Controller * USB 2.0 Virtual Hub * USB 1.1 HID Controller Pins for three ports are routed to the three controllers such that: * Port 1 is a dedicated USB 1.1 host port * Port 2 is shared between the USB 1.1 host and HID controllers * Port 3 is shared between the USB 2.0 host and Hub controllers As the pins for port 1 are fixed function there is no associated mux function or group described in the bindings. Ports 2 and 3 are muxed as above, and the table below describes the mapping between pinmux function names and ports: Port | USB Version | USB Mode | Mux Function ------|--------------|-----------|------------- 1 | 1.1 | Host | - 2 | 1.1 | Host | USB11H2 2 | 1.1 | HID | USB11D1 3 | 2.0 | Host | USB2H1 3 | 2.0 | Device | USB2D1 Signed-off-by: Andrew Jeffery <andrew@aj.id.au> Acked-by: Rob Herring <robh@kernel.org> --- v1 -> v2: * Updated the commit message to clarify HID details Documentation/devicetree/bindings/pinctrl/pinctrl-aspeed.txt | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/pinctrl/pinctrl-aspeed.txt b/Documentation/devicetree/bindings/pinctrl/pinctrl-aspeed.txt index ca01710ee29a..09142dab47db 100644 --- a/Documentation/devicetree/bindings/pinctrl/pinctrl-aspeed.txt +++ b/Documentation/devicetree/bindings/pinctrl/pinctrl-aspeed.txt @@ -69,8 +69,9 @@ PWM1 PWM2 PWM3 PWM4 PWM5 PWM6 PWM7 RGMII1 RGMII2 RMII1 RMII2 ROM16 ROM8 ROMCS1 ROMCS2 ROMCS3 ROMCS4 RXD1 RXD2 RXD3 RXD4 SALT1 SALT2 SALT3 SALT4 SD1 SD2 SGPMCK SGPMI SGPMLD SGPMO SGPSCK SGPSI0 SGPSI1 SGPSLD SIOONCTRL SIOPBI SIOPBO SIOPWREQ SIOPWRGD SIOS3 SIOS5 SIOSCI SPI1 SPI1DEBUG SPI1PASSTHRU SPICS1 TIMER3 TIMER4 -TIMER5 TIMER6 TIMER7 TIMER8 TXD1 TXD2 TXD3 TXD4 UART6 USBCKI VGABIOS_ROM VGAHS -VGAVS VPI18 VPI24 VPI30 VPO12 VPO24 WDTRST1 WDTRST2 +TIMER5 TIMER6 TIMER7 TIMER8 TXD1 TXD2 TXD3 TXD4 UART6 USB11D1 USB11H2 USB2D1 +USB2H1 USBCKI VGABIOS_ROM VGAHS VGAVS VPI18 VPI24 VPI30 VPO12 VPO24 WDTRST1 +WDTRST2 aspeed,ast2500-pinctrl, aspeed,g5-pinctrl: -- 2.11.0
