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>

2018-11-14regmap: Support reading from specific rangeMario Six
It is useful to be able to treat the different ranges of a regmap separately to be able to use distinct offset for them, but this is currently not implemented in the regmap API. To preserve backwards compatibility, add regmap_read_range and regmap_write_range functions that take an additional parameter 'range_num' that identifies the range to operate on.

2018-11-14regmap: Add raw read/write functionsMario Six
The regmap functions currently assume that all register map accesses have a data width of 32 bits, but there are maps that have different widths. To rectify this, implement the regmap_raw_read and regmap_raw_write functions from the Linux kernel API that specify the width of a desired read or write operation on a regmap. Implement the regmap_read and regmap_write functions using these raw functions in a backwards-compatible manner.

2018-11-14dm: core: Mirror the chosen node parse logic in the livetree scanningBin Meng
Commit f2006808f099: ("dm: core: parse chosen node") added a logic to parse the chosen node during dm_scan_fdt_node(), but unfortunately it missed adding the same logic in dm_scan_fdt_live(). This mirrors the logic in the livetree version. The weird thing is that commit f2006808f099 did update the test case to test such logic, but even if I reset to that commit, the test case still fails, and I have no idea how it could pass. With this fix, the following 2 test cases now pass: Test: dm_test_bus_children: bus.c test/dm/bus.c:112, dm_test_bus_children(): num_devices == list_count_items(&uc->dev_head): Expected 7, got 6 Test: dm_test_fdt: test-fdt.c test/dm/test-fdt.c:184, dm_test_fdt(): num_devices == list_count_items(&uc->dev_head): Expected 7, got 6 Fixes: f2006808f099 ("dm: core: parse chosen node") Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

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.

2018-11-05net: phy: mscc: add support for VSC8574 PHYQuentin Schulz
The VSC8574 PHY is a 4-port PHY that is 10/100/1000BASE-T, 100BASE-FX, 1000BASE-X and triple-speed copper SFP capable, can communicate with the MAC via SGMII, QSGMII or 1000BASE-X, supports WOL, downshifting and can set the blinking pattern of each of its 4 LEDs, supports SyncE as well as HP Auto-MDIX detection. This adds support for 10/100/1000BASE-T and SGMII/QSGMII link with the MAC. The VSC8574 has also an internal Intel 8051 microcontroller whose firmware needs to be patched when the PHY is reset. If the 8051's firmware has the expected CRC, its patching can be skipped. The microcontroller can be accessed from any port of the PHY, though the CRC function can only be done through the PHY that is the base PHY of the package (internal address 0) due to a limitation of the firmware. The GPIO register bank is a set of registers that are common to all PHYs in the package. So any modification in any register of this bank affects all PHYs of the package.
