[PATCH v3 0/4] imx6ul: add Technexion Pico Hobbit support

[Michael Grzeschik]

This series adds support for the Technexion Pico Hobbit. It also
prepares the TX_CLK_DIR pins for imx6ul platforms. This way it
will not be needed in every imx6ul based board files. We also
add support for post PHY reset delay as this is needed for the
pico hobbit.

[PATCH v3 1/4] ARM: i.MX: setup ENET_TX_CLK_DIR in imx6_init for every imx6ul

[Michael Grzeschik]

We generically enable the output of ENET_TX_CLK.
It will be output if ENET_REF_CLK is selected.

[PATCH v3 2/4] ARM: phytec-som-imx6: remove needles enet refclk setup

[Michael Grzeschik]

All REF_CLK output setup now is generically prepared for imx6ul. The
handling of the ENET_CLK_SEL (gpr[13]|gpr[14]) bits is not necessary, as
0 is their reset value.

[PATCH v3 3/4] i.MX: fec: add post PHY reset delay DT property

[Michael Grzeschik]

Some PHY require to wait for a bit after the reset GPIO has been
toggled. This adds support for the DT property `phy-reset-post-delay`
which gives the delay in milliseconds to wait after reset.

If the DT property is not given, no delay is observed. Post reset
delay greater than 1000ms are invalid.

[PATCH v3 4/4] ARM: i.MX6: add Technexion Pico Hobbit support

[Michael Grzeschik]

This adds support for the i.MX6UL Technexion Pico Hobbit. The board
comes with different amounts of RAM. We create one image for the 256MB
and one for the 512MB variant.

   ---
   v1 -> v2: - removed already prepared clock setup
   v2 -> v3: - added phy-reset-post-delay as the support is now available
