Use GPIO support by adding SD card detection configuration and
GPIO pinmux for Colibri's standard GPIO pins.
|
|
|
|
|
|
The GW52xx baseboard supports CANbus so we enable it, configure its pinmux
and CAN_STBY gpio.

Follow the conventions for pinctrl:
- grouping pinctrl in logical alphabatized groups
- remove any pinctrl not being used by a driver or needed by user
- move iomuxc to bottom of file for readability

The general device-tree rule is to not include nodes that do not have a driver
or bindings in a dts/dtsi. Remove the place-holder nodes from the Gateworks
Ventana boards until a time that a driver with proper bindings exists.

The spi-mxs driver does not allow full duplex SPI transfers. The
spi-gpio driver may be used as an alternative if this is required.
Make the choice between those drivers easier for the end user by
providing settings for both drivers.

The rtc isl1208 driver is used by mx6 nitrogen board, so let's enable it by
default.
Generated this patch by doing:
- make imx_v6_v7_defconfig
- make menuconfig and manually select CONFIG_RTC_DRV_ISL1208
- make savedefconfig
- cp defconfig arch/arm/configs/imx_v6_v7_defconfig
,which results in some additional cleanups.

Passing '0x80000000' to the pin configuration means that kernel will skip the
IOMUXC_SW_PAD_CTL configuration and will use whathever values come from the
bootloader.
Instead of relying on the bootloader setup, let's configure it in the kernel to
have predictable settings.
'0x1b0b0' is the default POR value for all these pins and has also been verified
that the pins are using this value by manually inspecting the IOMUXC_SW_PAD_CTL
registers, so no functional change has been made.

The imx6q clock driver currently hard-codes all PLL clocks to source
from OSC24M without BYPASS support. The patch adds the missing lvds_in
clock which is mutually exclusive with lvds_gate, and implements BYPASS
and BYPASS_CLK_SRC selection for PLL clocks as per Figure 10-3. Primary
Clock Generation in IMX6DQRM, i.e. both BYPASS_CLK_SRC and BYPASS bits
are implemented as mux clocks, and ENABLE bit of PLL clocks is
implemented as a gate clock after BYPASS mux.

There are a couple of gate clocks are mutually exclusive on i.MX6, i.e.
LVDSCLK1_IBEN and LVDSCLK1_OBEN. They cannot be enabled simultaneously.
This patches adds an exclusive gate clock type specifically for such
case. The clock driver will need to call imx_clk_gate_exclusive() to
register a gate clock with parameter exclusive_mask indicating the mask
of gate bits which are mutually exclusive to this gate clock.
Right now, it only handles the exclusive gate clocks which are defined
in a single hardware register, which is the case we're running into
today. But it can be extended to handle exclusive gate clocks defined
in different registers later if needed.
