pinctrl: a3700: Fix the issue that gpio controller is registered with wrong node id

2017-06-23T05:09:40+00:00

In armada_37xx_gpiochip_register, the return value of fdtdec_get_bool
should be true when gpio-controller is found; current codes makes a
wrong inverse return value judgement, this patch fixes it.

pinctrl: a3700: Fix uart2 group selection register mask

2017-06-23T05:09:40+00:00

If north bridge selection register bit1 is clear, pins [10:8] are for
SDIO0 Resetn, Wakeup, and PDN while if bit1 is set, pins [10:8]are for
GPIO; when bit1 is clear, pin 9 and pin 10 can be used for uart2 RTSn
and CTSn, so bit1 should be added to uart2 group and it must be set
for both "gpio" and "uart" functions of uart2 group.

stm32: stm32f7: add spl build support

2017-06-09T15:23:55+00:00

This commit supports booting from stm32 internal nor flash. spl U-Boot
initializes the sdram memory, copies next image (e.g. standard U-Boot)
to sdram & then jumps to entry point.

Here are the flash memory addresses for U-Boot-spl & standard U-Boot:
	- spl U-Boot		: 0x0800_0000
	- standard U-Boot	: 0x0800_8000

To compile u-boot without spl: Remove SUPPORT_SPL configuration
(arch/arm/mach-stm32/Kconfig)

rockchip: pinctrl: rk3328: do not set io routing

2017-06-07T13:29:21+00:00

In rk3328, some function pin may have more than one choice, and muxed
with more than one IO, for example, the UART2 controller IO,
TX and RX, have 3 choice(setting in com_iomux):
- M0 which mux with GPIO1A0/GPIO1A1
- M1 which mux with GPIO2A0/GPIO2A1
- usb2phy which mux with USB2.0 DP/DM pin.

We should not decide which group to use in pinctrl driver,
for it may be different in different board, it should goes to board
file, and the pinctrl file should setting correct iomux depends on
the com_iomux value.

dm: core: Update device_bind_driver_to_node() to use ofnode

Adjust this function to us an ofnode instead of an offset, so it can be

dm: core: Replace of_offset with accessor (part 2)

2017-06-01T13:03:04+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.
