From 517c4c44b32372d2fdf4421822e21083c45e89f9 Mon Sep 17 00:00:00 2001 From: Al Cooper Date: Mon, 12 Oct 2020 16:00:07 -0400 Subject: usb: Add driver to allow any GPIO to be used for 7211 USB signals The Broadcom 7211 has new functionality that allows some USB low speed side band signals, that go from the XHCI host controller to pins on the chip, to be remapped to use any GPIO pin instead of the limited set selectable by hardware. This can be done without changing the standard driver for the host controller. There is currently support for three USB signals, PWRON, VBUS_PRESENT and PWRFLT. This driver will allow the remapping of any of these three signals based on settings in the Device Tree node for the driver. The driver was written so that it could handle additional signals added in the future by just adding the correct properties to the DT node. Below is an example of a DT node that would remap all three signals: usb_pinmap: usb-pinmap@22000d0 { compatible = "brcm,usb-pinmap"; reg = <0x22000d0 0x4>; in-gpios = <&gpio 18 0>, <&gpio 19 0>; brcm,in-functions = "VBUS", "PWRFLT"; brcm,in-masks = <0x8000 0x40000 0x10000 0x80000>; out-gpios = <&gpio 20 0>; brcm,out-functions = "PWRON"; brcm,out-masks = <0x20000 0x800000 0x400000 0x200000>; interrupts = <0x0 0xb2 0x4>; }; Signed-off-by: Al Cooper Link: https://lore.kernel.org/r/20201012200007.8862-3-alcooperx@gmail.com Signed-off-by: Greg Kroah-Hartman --- MAINTAINERS | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'MAINTAINERS') diff --git a/MAINTAINERS b/MAINTAINERS index e73636b75f29..a6818b37704d 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -3572,6 +3572,14 @@ S: Maintained F: Documentation/devicetree/bindings/usb/brcm,bcm7445-ehci.yaml F: drivers/usb/host/ehci-brcm.* +BROADCOM BRCMSTB USB PIN MAP DRIVER +M: Al Cooper +L: linux-usb@vger.kernel.org +L: bcm-kernel-feedback-list@broadcom.com +S: Maintained +F: Documentation/devicetree/bindings/usb/brcm,usb-pinmap.yaml +F: drivers/usb/misc/brcmstb-usb-pinmap.c + BROADCOM BRCMSTB USB2 and USB3 PHY DRIVER M: Al Cooper L: linux-kernel@vger.kernel.org -- cgit v1.2.3 From 4e58171aa93fe8caf4f6e5e9972b7abe117c0014 Mon Sep 17 00:00:00 2001 From: Isaac Hazan Date: Tue, 3 Nov 2020 15:57:32 +0300 Subject: MAINTAINERS: Add Isaac as maintainer of Thunderbolt DMA traffic test driver I will be maintaining the Thunderbolt DMA traffic test driver.
