2019-10-25mtd: spi-nor-core: Replace MTD_SPI_NOR_USE_4K_SECTORS with ↵Vignesh Raghavendra
SPI_FLASH_USE_4K_SECTORS U-Boot uses CONFIG_SPI_FLASH_USE_4K_SECTORS to enable 4K small sector support. Use that instead of MTD_SPI_NOR_USE_4K_SECTORS.

SPI_SUNXI driver is fully dm-aware and the Allwinner architecture kconfig would have logic to enable the DM_SPI. So, select default spi sunxi driver for sunxi architecture. Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>
2019-10-25mtd: spi: Kconfig: Imply SPI_FLASH if DM_SPI_FLASHJagan Teki
DM_SPI_FLASH should require spi flash interface code for dm version, so imply SPI_FLASH core by default if any board enabled DM_SPI_FLASH. This overcome the explicit enablement of CONFIG_SPI_FLASH on respective boards when DM_SPI_FLASH being used.

2019-10-25dm: spi: Change cs_info op to return -EINVAL for invalid cs numBin Meng
We need distinguish the following two situations in various SPI APIs: - given chip select num is invalid - given chip select num is valid, but no device is attached Currently -ENODEV is returned for both cases. For the first case, it's more reasonable to return -EINVAL instead of -ENODEV for invalid chip select numbers.

1) CONFIG_SPI_FLASH is not just a legacy code, but it has common core code which handle both dm and non-dm spi flash code. So fix the info text to make it clear globally. 2) Since it's flash core it shouldn't depends on legacy SPI, so remove the 'depends on SPI' Cc: Vignesh R <vigneshr@ti.com> Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>

The ULP has two USB controllers. These two controllers have similar NC registers layout as i.MX7D. But OTG0 uses UTMI PHY simliar as i.MX6, not the integrated PHY on i.MX7D.

2019-10-24usb: ehci-mx6: Fix bus enumeration for iMX7 SoCsIgor Opaniuk
This fixes the issues with calculation of controller indexes in ehci_usb_bind() for iMX7, as USB controllers on iMX7 SoCs aren't placed next to each other, and their addresses incremented by 0x10000. Example of USB nodes for iMX7S/D: usbotg1: usb@30b10000 { compatible = "fsl,imx7d-usb", "fsl,imx27-usb"; reg = <0x30b10000 0x200>; ^^^^^^^^^^ .... usbotg2: usb@30b20000 { compatible = "fsl,imx7d-usb", "fsl,imx27-usb"; reg = <0x30b20000 0x200>; ^^^^^^^^^^ .... usbh: usb@30b30000 { compatible = "fsl,imx7d-usb", "fsl,imx27-usb"; reg = <0x30b30000 0x200>; ^^^^^^^^^^ .... Which was leading to usb enumeration issues: Colibri iMX7 # usb start starting USB...

2019-10-24phy: keystone-usb: handle the transition of the USB power domainJean-Jacques Hiblot
There is no proper power domain support for the keystone platforms. However we need to turn off the USB domains before jumping to linux or it fail to boot (observed with k2e and k2l platforms).

2019-10-24usb: dwc3: Kconfig: get rid of obsolete mode selectionJean-Jacques Hiblot
The mode selection for the DWC3 is kind of obsolete. The driver does not have to be host only or gadget only. This choice is confusing. All the remaining callers of dwc3_uboot_init() explicitly set dr_mode before calling the function, so none rely on a default behavior. Remove the choice menu and keep only the USB_DWC3_GADGET option. Enable it by default if USB_GADGET and USB_DWC3 are enabled. It must be disabled for the evb-rk3328 as it uses DWC2 for the gadget and DWC3 for the host.

2019-10-24usb: dwc3: Add dwc3_of_parse() to get quirks information from DTJean-Jacques Hiblot

2019-10-24usb: dwc3-generic: add a new host driver that uses the dwc3 coreJean-Jacques Hiblot
Currently the host driver used by dwc3-generic is "xhci-dwc3". This is a functional driver but it doesn't use the dwc3 core and, in particular, it lacks some bits that may be important. For example on the k2 platforms, it is important that the phy are properly suspended when the USB is not used anymore. The dwc3 core also has a partial support for quirks. The new driver can be used as a drop-in replacement for "xhci-dwc3". In terms of implementation, it may seem strange that 2 private structures dwc3_generic_host_priv and dwc3_generic_priv) are used. The reason for this is simply that the xhci layer expects a struct xhci_ctrl at the beginning of the private data and it seemed wasteful to include it also for the peripheral case.

2019-10-22drivers: clk: Fix using assigned-clocks in the node of the clock it sets upJean-Jacques Hiblot
This fixes the case where assigned-clocks is used to define a clock defaults inside this same clock's node. This is used sometimes to setup a default parents and/or rate for a clock. example: muxed_clock: muxed_clock { clocks = <&clk_provider 0>, <&clk_provider 1>; #clock-cells = <0>; assigned-clocks = <&muxed_clock>; assigned-clock-parents = <&clk_provider 1>; }; It doesn't work in u-boot because the assigned-clocks are setup *before* the clock is probed. (clk_set_parent() will likely crash or fail if called before the device probe function) Making it work by handling "assigned-clocks" in 2 steps: first before the clk device is probed, and then after the clk device is probed.
