Subject: [PATCH v2 0/6] arm: sunxi: IR support for A83T

This patch series adds support for the sunxi A83T ir module and enhances 
the sunxi-ir driver. Right now the base clock frequency for the ir driver
is a hard coded define and is set to 8 MHz.
This works for the most common ir receivers. On the Sinovoip Bananapi M3 
the ir receiver needs, a 3 MHz base clock frequency to work without
problems with this driver.

This patch series adds support for an optinal property that makes it able
to override the default base clock frequency and enables the ir interface 
on the a83t and the Bananapi M3.

changes since v1:
* fix typos, reword Documentation
* initialize 'b_clk_freq' to 'SUNXI_IR_BASE_CLK' & remove if statement
* change dev_info() to dev_dbg()
* change naming to cir* in dts/dtsi
* Added acked Ackedi-by to related patch
* use whole memory block instead of registers needed + fix for h3/h5

changes since rfc:
* The property is now optinal. If the property is not available in 
  the dtb the driver uses the default base clock frequency.
* the driver prints out the the selected base clock frequency.
* changed devicetree property from base-clk-frequency to clock-frequency

Regards,
Philipp
