ARM: tegra: Add support for TK1-SOM board from Colorado Engineering

2016-09-01T16:24:30+00:00

The Colorado TK1 SOM is a small form factor board similar to the
Jetson TK1.  The main differences lie in the pinmux, and in that the
PCIe controller is set to use in 4lanes+1lane, rather than 2+2.

The pinmux header here was generated from a spreadsheet provided by
Colorado Engineering using the tegra-pinmux scripts.  The spreadsheet
was converted from v09 to v11 by me.

ARM: tegra: set vdd_core for Jetson TK1

2016-08-15T17:26:14+00:00

Program vdd_core for Jetson TK1 to 1V, which is the max safe voltage for
ultra low temperature operations. vdd_cpu and vdd_gpu are already at 1V.

ARM: tegra: enable PCIe controller on p2771-0000

2016-08-15T17:26:13+00:00

p2771-0000 has a couple of PCIe ports; one physically x4 desktop PCI
connector (which may run at x2 electrically, depending on the board
version and configuration) and a x1 connection to the M.2 slot (which may
not be active, depending on the board version and configuration). This
change enables those.

ARM: tegra: enable SD card on p2771-0000

2016-08-15T17:26:13+00:00

Now that clock and reset drivers exist for Tegra186, we can enable the SD
card controller. Now that a BPMP I2C driver exists for Tegra186, we can
communicate with the PMIC to enable power to the SD card. Hook up the DT
content and board code required to make the SD card work.

ARM: tegra: p2371-2180: A03 board PMIC config update

2016-07-21T16:31:30+00:00

Rev A03 of P2180 requires some PMIC programming adjustments, yet the
PMIC's own OTP has not been updated. Consequently, U-Boot must make
these changes itself.

NVIDIA's syseng team has confirmed that these changes can be enabled on
all board revisions without issue.

ARM: tegra: add p2771-0000 board support

2016-05-31T18:22:59+00:00

P2771-0000 is a P3310 CPU board married to a P2597 I/O board. The
combination contains SoC, DRAM, eMMC, SD card slot, HDMI, USB micro-B
port, Ethernet, USB3 host port, SATA, PCIe, and two GPIO expansion
headers.

Currently, due to U-Boot's level of support for Tegra186, the only
features supported by U-Boot are the console UART and the on-board eMMC.
Additional features will be added over time.

U-Boot has so far been tested by replacing the kernel image on the device
with a U-Boot binary. It is anticipated that U-Boot will eventually
replace the CCPLEX bootloader binary, as on previous chips. This hasn't
yet been tested.

ARM: tegra: use DT bindings for GPIO naming

2016-05-31T16:53:56+00:00

There are currently many places that define the list of all Tegra GPIOs;
the DT binding header and custom Tegra-specific header file gpio.h. Fix
the redundancy by replacing everything with the DT binding header file.

ARM: tegra: import latest Jetson TK1 spreadsheet

2016-05-04T20:31:04+00:00

This imports v11 of "Jetson TK1 Development Platform Pin Mux" from
https://developer.nvidia.com/embedded/downloads.

The new version defines the mux option for the MIPI pad ctrl selection.
The OWR pin no longer has an entry in the configuration table because
the only mux option it support is OWR, that feature isn't supported, and
hence can't conflict with any other pin. This pin can only usefully be
used as a GPIO.

ARM: tegra: rm Jetson TK1 PMIC GPIO programming

2016-01-28T17:32:31+00:00

The PMIC is configured such that its GPIOs have the correct configuration
at power-up, so no programming is required.

In fact, the current programming is actively wrong, since:

(a) the AS3722 driver configures the GPIO to be an output before setting
its output value, which causes a 0v glitch on the output.

(b) the AS3722 driver configures the GPIO to drive a high voltage from its
VSUP_GPIO power source rather than its VDD_GPIO_LV power source, so the pin
drives 5V not 1.8V as desired.

Solve these problems by removing the code which configures the PMIC GPIOs.

Note that this patch was tested directly on top of v2016.01; since then,
commit 96350f729c42 "dm: tegra: net: Convert tegra boards to driver model
for Ethernet" prevents PCIe from being initialized. Alternatively, simply
revert that commit to get PCIe Ethernet working again, then apply this
patch to test.
