It describes various plls and soc specific details for the particular SOC based on bcm iproc architecture. the core functionality is implemented for all Broadcom SOC using iproc pll architecture in generic iproc drivers eg: clk-iproc-pll.c > > > +CLK_OF_DECLARE(sr_genpll0_clk, "brcm,sr-genpll0", > > + sr_genpll0_clk_init); > > + > > +static const struct iproc_pll_ctrl genpll3 = { > > + .flags = IPROC_CLK_AON | IPROC_CLK_PLL_HAS_NDIV_FRAC | > > + IPROC_CLK_PLL_NEEDS_SW_CFG, > > + .aon = AON_VAL(0x0, 1, 19, 18), > > + .reset = RESET_VAL(0x0, 12, 11), > > + .dig_filter = DF_VAL(0x0, 4, 3, 0, 4, 7, 3), > > + .sw_ctrl = SW_CTRL_VAL(0x10, 31), > > + .ndiv_int = REG_VAL(0x10, 20, 10), > > + .ndiv_frac = REG_VAL(0x10, 0, 20), > > + .pdiv = REG_VAL(0x14, 0, 4), > > + .status = REG_VAL(0x30, 12, 1), > > +}; > > + > > +static const struct iproc_clk_ctrl genpll3_clk[] = { > > + [BCM_SR_GENPLL3_HSLS_CLK] = { > > + .channel = BCM_SR_GENPLL3_HSLS_CLK, > > + .flags = IPROC_CLK_AON, > > + .enable = ENABLE_VAL(0x4, 6, 0, 12), > > + .mdiv = REG_VAL(0x18, 0, 9), > > + }, > > + [BCM_SR_GENPLL3_SDIO_CLK] = { > > + .channel = BCM_SR_GENPLL3_SDIO_CLK, > > + .flags = IPROC_CLK_AON, > > + .enable = ENABLE_VAL(0x4, 7, 1, 13), > > + .mdiv = REG_VAL(0x18, 10, 9), > > + }, > > +}; > > + > > +static void __init sr_genpll3_clk_init(struct device_node *node) > > +{ > > + iproc_pll_clk_setup(node, &genpll3, NULL, 0, genpll3_clk, > > + ARRAY_SIZE(genpll3_clk)); > > +} > > +CLK_OF_DECLARE(sr_genpll3_clk, "brcm,sr-genpll3", > > + sr_genpll3_clk_init); > > Can you make this a platform driver instead? Are all these clks > really used for getting the interrupt and timers running? Not all clocks needed early except the genpll3. sp804 timer clks are derived from genpll. we will send revised patch to have most of the clocks registered via platform driver probe. > > > + > > +static const struct iproc_pll_ctrl genpll4 = { > > + .flags = IPROC_CLK_AON | IPROC_CLK_PLL_HAS_NDIV_FRAC | > > + IPROC_CLK_PLL_NEEDS_SW_CFG, > > + .aon = AON_VAL(0x0, 1, 25, 24), > > + .reset = RESET_VAL(0x0, 12, 11), > > + .dig_filter = DF_VAL(0x0, 4, 3, 0, 4, 7, 3), > > + .sw_ctrl = SW_CTRL_VAL(0x10, 31), > > + .ndiv_int = REG_VAL(0x10, 20, 10), > > + .ndiv_frac = REG_VAL(0x10, 0, 20), > > + .pdiv = REG_VAL(0x14, 0, 4), > > + .status = REG_VAL(0x30, 12, 1), > > +}; > > + > > +static const struct iproc_clk_ctrl genpll4_clk[] = { > > + [BCM_SR_GENPLL4_CCN_CLK] = { > > + .channel = BCM_SR_GENPLL4_CCN_CLK, > > + .flags = IPROC_CLK_AON, > > + .enable = ENABLE_VAL(0x4, 6, 0, 12), > > + .mdiv = REG_VAL(0x18, 0, 9), > > + }, > > +}; > > + > > -- > Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, > a Linux Foundation Collaborative Project regards Sandeep -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
