2018-11-14dm: Add a new uclass driver for VirtIO transport devicesBin Meng
This adds a new virtio uclass driver for “virtio” [1] family of devices that are are found in virtual environments like QEMU, yet by design they look like physical devices to the guest. The uclass driver provides child_pre_probe() and child_post_probe() methods to do some common operations for virtio device drivers like device and driver supported feature negotiation, etc. [1] http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.pdf Signed-off-by: Tuomas Tynkkynen <tuomas.tynkkynen@iki.fi> Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-11-14dm: core: Allow uclass to set up a device's child after it is probedBin Meng
Some buses need to set up their child devices after they are probed. Support a common child_post_probe() method for the uclass. With this change, the two APIs uclass_pre_probe_device() and uclass_post_probe_device() become symmetric. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-11-14dm: Correct pre_reloc_only parameter description in several APIs' commentsBin Meng

2018-11-14dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()Bin Meng
Currently the comments of several APIs (eg: dm_init_and_scan()) say: @pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC flag. If false bind all drivers. The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt documents the same that both device tree properties and driver flag are supported. However the implementation only checks these special device tree properties without checking the driver flag at all. This updates lists_bind_fdt() to consider both scenarios.

2018-10-07Add UCLASS_TEE for Trusted Execution EnvironmentJens Wiklander
Adds a uclass to interface with a TEE (Trusted Execution Environment). A TEE driver is a driver that interfaces with a trusted OS running in some secure environment, for example, TrustZone on ARM cpus, or a separate secure co-processor etc. The TEE subsystem can serve a TEE driver for a Global Platform compliant TEE, but it's not limited to only Global Platform TEEs. The over all design is based on the TEE subsystem in the Linux kernel, tailored for U-Boot.

2018-09-29drivers: Add board uclassMario Six
Since there is no canonical "board device" that can be used in board files, it is difficult to use DM function for board initialization in these cases. Hence, add a uclass that implements a simple "board device", which can hold devices not suitable anywhere else in the device tree, and is also able to read encoded information, e.g. hard-wired GPIOs on a GPIO expander, read-only memory ICs, etc. that carry information about the hardware. The devices of this uclass expose methods to read generic data types (integers, strings, booleans) to encode the information provided by the hardware.
