[U-Boot] [PATCH V3 01/11] dm: gpio: uclass: Add flag to control sequence numbering

[Bhuvanchandra DV]

Like SPI and I2C few GPIO controllers also have
multiple chip instances. This patch adds the
flag 'DM_UC_FLAG_SEQ_ALIAS' in gpio_uclass driver
to control device sequence numbering. By defalut
the dev->r_seq for gpio_uclass will alwalys
returns -1, which leads the gpio driver probe
failure when using the driver with device trees.

Fixed by applying:

WARNING: line over 80 characters

#274: FILE: drivers/gpio/vybrid_gpio.c:74:
+	if (((g_state & (0x07 << PAD_MUX_MODE_SHIFT)) >> PAD_MUX_MODE_SHIFT) > 0)

Applied to u-boot-imx, thanks !

[U-Boot] [PATCH V3 03/11] colibri_vf: Add pinmux entries for GPIOs

[Bhuvanchandra DV]

Inorder to use the pins as GPIO, apart from setting the alt-function,
pinmuxing need to be done, this patch adds pinmux entries of
few GPIOs.

[U-Boot] [PATCH V3 09/11] colibri_vf: Add separate defconfig for device tree support

[Bhuvanchandra DV]

Most of the drivers available for Vybrid are not yet converted
to OF model to use device tree model, only few drivers
like SPI and GPIO drivers use device trees.
Add separate defconfig for who needs to use device tree model.
Later this can be integrated to single defconfig.

[U-Boot] [PATCH V3 10/11] usb: ehci-vf: Add weak function for board specific initialisation

[Bhuvanchandra DV]

From: Sanchayan Maity <maitysanchayan@gmail.com>

Add a weak function board_ehci_hcd_init which can be used by the board
file for board specific initialisation.

[U-Boot] [PATCH V3 11/11] colibri_vf: Enable board specific USB initialisation for USB pen gpio

[Bhuvanchandra DV]

From: Sanchayan Maity <maitysanchayan@gmail.com>

Add IOMUX for the pad used as USB pen. This needs to be driven low for
the Iris and Viola boards where it is pulled up high by default. This is
required for the USB host functionality to work on these boards. Use the
board specific weak initialisation function, to drive the pin low which
would be called on "usb start".
