ARM: tegra: Implement cboot_get_ethaddr()

2019-06-05T16:16:34Z

This function will attempt to look up an Ethernet address in the DTB that was passed in from cboot. It does so by first trying to locate the default Ethernet device for the board (identified by the "ethernet" alias) and if found, reads the "local-mac-address" property. If the "ethernet" alias does not exist, or if it points to a device tree node that doesn't exist, or if the device tree node that it points to does not have a "local-mac-address" property or if the value is invalid, it will fall back to the legacy mechanism of looking for the MAC address stored in the "nvidia,ethernet-mac" or "nvidia,ether-mac" properties of the "/chosen" node. The MAC address is then written to the default Ethernet device for the board (again identified by the "ethernet" alias) in U-Boot's control DTB. This allows the device driver for that device to read the MAC address from the standard location in device tree. Signed-off-by: Thierry Reding Signed-off-by: Tom Warren

ARM: tegra: Unify Tegra186 builds

2019-06-05T16:16:34Z

Tegra186 build are currently dealt with in very special ways, which is because Tegra186 is fundamentally different in many respects. It is no longer necessary to do many of the low-level programming because early boot firmware will already have taken care of it. Unfortunately, separating Tegra186 builds from the rest in this way makes it difficult to share code with prior generations of Tegra. With all of the low-level programming code behind Kconfig guards, the build for Tegra186 can again be unified. As a side-effect, and partial reason for this change, other Tegra SoC generations can now make use of the code that deals with taking over a boot from earlier bootloaders. This used to be nvtboot, but has been replaced by cboot nowadays. Rename the files and functions related to this to avoid confusion. The implemented protocols are unchanged.

ARM: tegra: Support TZ-only access to PMC

2019-06-05T16:16:34Z

Some devices may restrict access to the PMC to TrustZone software only. Non-TZ software can detect this and use SMC calls to the firmware that runs in the TrustZone to perform accesses to PMC registers. Note that this also fixes reset_cpu() and the enterrcm command on Tegra186 where they were previously trying to access the PMC at a wrong physical address. Based on work by Kalyani Chidambaram and Tom Warren . Signed-off-by: Thierry Reding Signed-off-by: Tom Warren

ARM: tegra: Use common header for PMU declarations

2019-06-05T16:16:33Z

There's no need to replicate the pmu.h header file for every Tegra SoC generation. Use a single header that is shared across generations. Signed-off-by: Thierry Reding Signed-off-by: Tom Warren

tegra: sound: Add an I2S driver

2019-05-24T17:14:03Z

Add a driver which supports transmitting digital sound to an audio codec. This uses fixed parameters as a device-tree binding is not currently defined. Signed-off-by: Simon Glass Acked-by: Jon Hunter Signed-off-by: Tom Warren

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

dm: tegra: Convert clock_decode_periph_id() to support livetree

dm: tegra: Convert USB setup to livetree

2017-07-28T18:02:47Z

Adjust this code to support a live device tree. This should be implemented as a PHY driver but that is left as an exercise for the maintainer. Signed-off-by: Simon Glass Tested-by: Stephen Warren

tegra: tegra124: Add a PMC syscon driver
