[U-Boot] [PATCH 02/14] imx: ventana: do not iomux UART1

[Tim Harvey]

The only UART that is garunteed on Ventana boards is UART2 (serial-console).

Remove UART1 pinmux as that it is not consistent across all Ventana boards
and U-Boot doesn't need it.

[U-Boot] [PATCH 03/14] imx: ventana: remove setup of I2C3 from SPL

[Tim Harvey]

Do not setup I2C3 in the SPL for Ventana as some devices on that bus
(aic3x codecs) can hang the bus causing i2c_setup to spin endlessly until
they are put into reset. Removing the setup of I2C3 from the SPL allows
the board-specific GPIO to be configured to take care of putting codecs
in reset prior to U-Boot setting up I2C3.

[U-Boot] [PATCH 14/14] imx: ventana: fix usage of dt paths with leading 0s (Linux 4.15+)

[Tim Harvey]

device-tree paths should never be used that reference node addresses
making an assumption about leading zeros. They should not be there per
the device-tree specification however they have been there until Linux
4.15 when they were removed via kernel commit
8dccafaa281aa1d240a58bbcdff338aec114a021.

This fixes various issues which will occur when using Linux 4.15+
that are being fixed up on a per model per PCB revision basis such as:
 - enabling MMC UHS-I on board revisions that support it
 - enabling PWM based on hwconfig
 - fixing PCIe reset on GW552x
 - removing cpu external watchdog reset on boards that do not support it
 - populate PCI dt nodes based on PCI scan in order to fix GW16082
   interrupt mapping and inject MAC address for PCI based GbE

[U-Boot] [U-Boot, 14/14] imx: ventana: fix usage of dt paths with leading 0s (Linux 4.15+)

[sbabic at denx.de]

> device-tree paths should never be used that reference node addresses
> making an assumption about leading zeros. They should not be there per
> the device-tree specification however they have been there until Linux
> 4.15 when they were removed via kernel commit
> 8dccafaa281aa1d240a58bbcdff338aec114a021.
> This fixes various issues which will occur when using Linux 4.15+
> that are being fixed up on a per model per PCB revision basis such as:
>  - enabling MMC UHS-I on board revisions that support it
>  - enabling PWM based on hwconfig
>  - fixing PCIe reset on GW552x
>  - removing cpu external watchdog reset on boards that do not support it
>  - populate PCI dt nodes based on PCI scan in order to fix GW16082
>    interrupt mapping and inject MAC address for PCI based GbE
> Signed-off-by: Tim Harvey <tharvey@gateworks.com>

Applied to u-boot-imx, master, thanks !

Best regards,
