[PATCH 1/4] udoo_neo: Call gpio_request()

[PATCH 1/4] udoo_neo: Call gpio_request()

[Peter Robinson]

Calling gpio_request() prior to its usage is now mandatory.

This fixes the following GPIO errors:
gpio@20a8000: set_dir_flags: error: gpio GPIO4_16 not reserved
gpio@20a8000: set_dir_flags: error: gpio GPIO4_13 not reserved
gpio@20a8000: set_dir_flags: error: gpio GPIO4_0 not reserved
gpio@20a8000: get_value: error: gpio GPIO4_13 not reserved
gpio@20a8000: get_value: error: gpio GPIO4_0 not reserved
gpio@20a0000: set_dir_flags: error: gpio GPIO2_1 not reserved
gpio@20a0000: set_value: error: gpio GPIO2_1 not reserved

Fixes: 191840ae99 ("ARM: imx: udoo_neo: Enable OF_CONTROL and DM gpio/pin control")

[PATCH 2/4] udoo_neo: Fixes for booting from the mSD card

[Peter Robinson]

This fixes booting from the mSD card from both SPL and when
using it for the OS booting. It also cleans up a few mmc
booting bits that are no longer needed.

[PATCH 3/4] udoo_neo: Fix ethernet

[Peter Robinson]

The ethernet has a RMII not RGMII, also needs DM_MDIO and finally
initialise it later in the process as it's not needed that early on
and not everything is ready so it locks up the device.
