  tty: serial: 8250_mtk: Add support for bus clock (2015-04-27 08:39:06 +0200)

----------------------------------------------------------------
This series adds support for the second clock on the Mediatek UART.
This is necessary for SoCs needing a bus clock to be enabled before
the UART can be accessed.

Changes since v1:
- keep support old binding with unnamed clk
- hopefully clarify commit message
- do not leak in if() with unnecessary braces.

----------------------------------------------------------------
Sascha Hauer (4):
      tty: serial: 8250_mtk: remove unnecessary test
      tty: serial: 8250_mtk: Use devm_clk_get
      tty: serial: 8250_mtk: use pm_runtime callbacks for enabling
      tty: serial: 8250_mtk: Add support for bus clock
