phy: Renesas R-Car gen3 PCIe PHY driver

2018-07-10T08:15:11+00:00

This PHY is still mostly undocumented -- the only documented registers exist on R-Car V3H (R8A77980) SoC where this PHY stays in a powered-down state after a reset and thus we must power it up for PCIe to work...

phy: rcar-gen3-usb2: select USB_COMMON

2017-12-15T10:30:41+00:00

When USB is disabled, we get a link error for this driver because of the added OTG support drivers/phy/renesas/phy-rcar-gen3-usb2.o: In function `rcar_gen3_phy_usb2_probe': phy-rcar-gen3-usb2.c:(.text+0x250): undefined reference to `of_usb_get_dr_mode_by_phy' Other phy drivers select USB_COMMON for this, so let's do the same here.

Chanwoo writes: Update extcon for 4.15 Detailed description for this pull request: 1. Split out extcon header file for consumer and provider device : The extcon has two type of extcon devices as following. - 'extcon provider deivce' adds new extcon device and detect the state/properties of external connector. Also, it notifies the state/properties to the extcon consumer device. - 'extcon consumer device' gets the change state/properties from extcon provider device. Prior to that, include/linux/extcon.h contains all exported API for both provider and consumer device driver. To clarify the meaning of header file and to remove the wrong use-case on consumer device. - include/linux/extcon-provider.h includes API for the provider device driver. - include/linux/extcon.h includes the API for the consumer device driver. 2. Support the SmartDock accessory on extcon-max77843.c device driver - Support the SmartDock accessory which detects following connectors at the same time. : USB host throught USB hub for mouse, keyboard and so on. : MHL connector for video output. : Charger connector for battery charging. - It tested with Unitek Y-2165 MHL+OTG Hub Smart Phone Dock. 3. Fix the minor issue of extcon driver - Delete the unneeded initialization in extcon-max14577. - Make extcon_info static const in order to fix the warning.

phy: rcar-gen3-usb2: add SoC-specific parameter for dedicated pins

2017-10-23T05:49:26+00:00

This patch adds SoC-specific parameter to avoid reading/writing specific registers wrongly if this driver runs on a SoC which doesn't have dedicated pins (e.g. R-Car D3). This patch also changes the value "has_otg" to "has_otg_pins" for slightly easier reading of the code.

phy: rcar-gen3-usb2: use enum phy_mode in the role_store()

This patch modifies the role_store() to use "enum phy_mode" instead of the local "bool" for host/device mode selection. Signed-off-by: Yoshihiro Shimoda Reviewed-by: Simon Horman Signed-off-by: Kishon Vijay Abraham I

phy: rcar-gen3-usb2: check dr_mode for otg mode

2017-10-23T05:49:26+00:00

The previous code assumed a channel has otg capability if a channel has interrupt property. But, it is not good because: - Battery charging feature also needs interrupt property. - Some R-Car Gen3 SoCs (e.g. R-Car D3) don't have OTG capability. So, this patch checks whether usb 2.0 host node has dr_mode property or not. If it has 'dr_mode = "otg";', this driver enables otg capability.
