Hi Philipp,

just a couple of small nitpicks.

[...]

> +	/* Base clock frequency (optional) */
> +	if (of_property_read_u32(dn, "clock-frequency", &b_clk_freq)) {
> +		b_clk_freq = SUNXI_IR_BASE_CLK;

how about you intialize 'b_clk_freq' to 'SUNXI_IR_BASE_CLK' and
just call 'of_property_read_u32' without if statement.
'b_clk_freq' value should not be changed if "clock-frequency"
is not present in the DTS.

This might avoid misinterpretation from static analyzers that
might think that 'b_clk_freq' is used uninitialized.

Please use dev_dbg().
