[PATCH v3 5/9] ARM/ASoC: omap-mcbsp: Remove CLKR/FSR mux configuration code

[tony@atomide.com (Tony Lindgren)]

* Peter Ujfalusi <peter.ujfalusi@ti.com> [120816 06:41]:
> Remove the feature to configure the CLKR/FSR mux on McBSP port with 6pin
> configuration.
> When moving to devicetree these callback can no longer be used in a clean
> way anymore.
> If a board require to change the 6pin port to work in 4pin setup it needs
> to set up the mux in the board file.
> For OMAP2/3:
> u32 devconf0;
> 
> /* McBSP1 CLKR/FSR signal to be connected to CLKX/FSX pin */
> devconf0 = omap_ctrl_readl(OMAP2_CONTROL_DEVCONF0);
> devconf0 |=  OMAP2_MCBSP1_CLKR_MASK | OMAP2_MCBSP1_FSR_MASK;
> omap_ctrl_writel(devconf0, OMAP2_CONTROL_DEVCONF0);
> 
> For OMAP4:
> u32 mcbsp_pad;
> 
> /* McBSP4 CLKR/FSR signal to be connected to CLKX/FSX pin */
> mcbsp_pad = omap4_ctrl_pad_readl(OMAP2_CONTROL_DEVCONF0);
> mcbsp_pad |=  ((1 << 31) | (1 << 30));
> omap4_ctrl_pad_writel(mcbsp_pad, OMAP2_CONTROL_DEVCONF0);
> 
> In case when the kernel is booted with DT blob the pinctrl-single will be
> provided as soon as it is enabled on the platform.
