That hunk was moved, see above. It's not the devicetree path, it's for
non-DT TI DaVinci:
arch/arm/mach-davinci/da850.c:static struct clk pruss_clk = {
arch/arm/mach-davinci/da850.c: .name = "pruss",
The DT path already has a clocks associated at the hwmod level.
>From arch/arm/mach-omap2/omap_hwmod_33xx_43xx_ipblock_data.c:
struct omap_hwmod am33xx_pruss_hwmod = {
.name = "pruss",
.class = &am33xx_pruss_hwmod_class,
.clkdm_name = "pruss_ocp_clkdm",
.flags = HWMOD_INIT_DEASSERT_HARD_RESET,
.main_clk = "pruss_ocp_gclk",
and doesn't require any additional clock entries as far as the binding is
concerned.
Thanks,
Andre
