| * clk: at91: update to PMC bindingsSam Ravnborg2019-02-2519-975/+620
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on kernel 5.0-rc6 update at91 clk support to match the new PMC bindings. Manually added all changes done in the kernel from 4.9-rc3 to 5.0-rc6. New drivers required was added as seperate commits. This includes dt-compat code required to support at91sam5d3, as this is not yet ported to use the new PMC bindings. clk-programmable saw some extra changes - it had never been bulit. It is used only by at91sama5d2 - and barebox has no board support for this cpu (yet). The CONFIG_SOC symbols is used to select the relevant drivers. CONFIG_SOC_SAM9 selects several drivers, and in the future this can be split to keep the image size down. In the kernel CLK_OF_DECLARE_DRIVER() can be used for a two step init. In barebox this is a simple one step init. It was added to have less differences between the kernel and the barebox versions of the drivers.

| | | | | | | | | | | | | | | | | | | | | | As the sama5d3 based microchip-ksz9477-evb board still uses the old bindings, the dt-compat.c code is ported as well. This can be removed when all in-kernel at91 boards have been ported to the new bindings.

* | defaultenv: Fix dependenciesSascha Hauer2019-02-272-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | The defaultenv should be rebuilt once a file in it has changed. the genenv script always generates the environment file to a temporary file. Only if it has changed to the last target file the temporary file is moved over the target file. This means we always have to call genenv, thus replace "if_changed" with "cmd". With this dependencies are correctly tracked. New or changed files result in new image builds whereas unchanged environments do not unnecessarily result in new images.

|/ | | | | | | | | | | | | Original code was written to exit early on ehci_register()'s success. As a part of e3eb0c729b, however, it was modified to to early exit on failure instead. This resulted in VBUS being erroneously disabled after EHCI controller was added, thus breaking USB on some i.MX boards (confirmed on ZII's RDU2).
