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.
