[PATCH 0/6] ARM: dts: am335x-sl50: Update to new hardware

[Enric Balletbo i Serra]

Hi Tony,

The following patches updates the device tree file for the SL50 device, there
are few v1 boards and IMHO doesn't make sense to maintain the device tree
for these old devices, so mostly of the updates are related to changes done in
the next hardware revision v2 (the one that will go out).

Best regards,

Enric Balletbo i Serra (6):
  ARM: dts: am335x-sl50: Remove I2C1 node.
  ARM: dts: am335x-sl50: Enable UART1.
  ARM: dts: am335x-sl50: Enable SPI0 interface and Flash Memory.
  ARM: dts: am335x-sl50: Enable BQ32000 Real Time Clock.
  ARM: dts: am335x-sl50: Enable the MCP23017 GPIO Expander.
  ARM: dts: am335x-sl50: Enable the Ambient Light Sensor.

[PATCH 1/6] ARM: dts: am335x-sl50: Remove I2C1 node.

[Enric Balletbo i Serra]

I2C1 is not used so remove it in order to avoid conflicts.

[PATCH 2/6] ARM: dts: am335x-sl50: Enable UART1.

[Enric Balletbo i Serra]

The UART1 is connected to the infrared (IR) receiver module, so enable it
to be able to comunicate with it.

This is only if the v1 boards are company internal and can be easily
replaced. As long as that's the case I'm fine with that.
