[PATCHv4 0/7] ARM: sunxi: Extend UART support for Allwinner SoCs

Hi,

This patchset reworks a bit the UART support that is found in the DT
for Allwinner SoCs, which was quite limited until now.

It first switches to using the clocks property, then rework a bit the
DTSI to have only the UART available in the A10 and the A13 (the A10
has 8 UARTs, while A13 has only the uart1 and uart3).

Thanks,
Maxime

Changes from v3:
  - Renamed uart nodes to serial
  - Reworked the patch for 8250_dw to use the IS_ERR macro for clocks error
    checking

Changes from v2:
  - Reworked Emilio's patch according to Heikki Krogerus' review to enable the
    use of the clock framework even when not using the dt
