The #ifdefs are needed to prevent compile errors until the entire ARCH_DAVINCI is converted. Also clean up the #includes since we are adding some here. Signed-off-by: David Lechner Reviewed-by: Sekhar Nori --- v9 changes: - register PLL in da830_init_time() instead of as platform device so that we get the correct timer0 clock for davinci_timer_init() v8 changes: - none v7 changes: - add clock platform device declarations - register platform devices instead of registering clocks directly - clkdev lookup is moved to drivers/clk - add davinci prefix to commit description v6 changes: - add blank lines between function calls - include da8xx_register_cfgchip() arch/arm/mach-davinci/board-da830-evm.c | 2 + arch/arm/mach-davinci/da830.c | 70 ++++++++++++++++++++-- arch/arm/mach-davinci/include/mach/da8xx.h | 1 + 3 files changed, 67 insertions(+), 6 deletions(-) diff --git a/arch/arm/mach-davinci/board-da830-evm.c b/arch/arm/mach-davinci/board-da830-evm.c index 004f9c8de032..3973124e5f1d 100644 --- a/arch/arm/mach-davinci/board-da830-evm.c +++ b/arch/arm/mach-davinci/board-da830-evm.c @@ -551,6 +551,8 @@ static __init void da830_evm_init(void) struct davinci_soc_info *soc_info = &davinci_soc_info; int ret; + da830_register_clocks(); + ret = da830_register_gpio(); if (ret) pr_warn("%s: GPIO init failed: %d\n", __func__, ret); diff --git a/arch/arm/mach-davinci/da830.c b/arch/arm/mach-davinci/da830.c index 0b17e5a22e5e..8a79e245db1f 100644 --- a/arch/arm/mach-davinci/da830.c +++ b/arch/arm/mach-davinci/da830.c @@ -8,23 +8,27 @@ * is licensed "as is" without any warranty of any kind, whether express * or implied. */ +#include +#include #include #include -#include #include #include -#include "psc.h" -#include -#include #include -#include +#include #include +#include +#include -#include "clock.h" #include "mux.h" +#ifndef CONFIG_COMMON_CLK +#include "clock.h" +#include "psc.h" +#endif + /* Offsets of the 8 compare registers on the da830 */ #define DA830_CMP12_0 0x60 #define DA830_CMP12_1 0x64 @@ -37,6 +41,7 @@ #define DA830_REF_FREQ 24000000 +#ifndef CONFIG_COMMON_CLK static struct pll_data pll0_data = { .num = 1, .phys_base = DA8XX_PLL0_BASE, @@ -432,6 +437,7 @@ static struct clk_lookup da830_clks[] = { CLK(NULL, "rmii", &rmii_clk), CLK(NULL, NULL, NULL), }; +#endif /* * Device specific mux setup @@ -1223,6 +1229,58 @@ void __init da830_init(void) void __init da830_init_time(void) { +#ifdef CONFIG_COMMON_CLK + void __iomem *pll; + struct clk *clk; + + clk_register_fixed_rate(NULL, "ref_clk", NULL, 0, DA830_REF_FREQ); + + pll = ioremap(DA8XX_PLL0_BASE, SZ_4K); + + da830_pll_init(NULL, pll, NULL); + + clk = clk_get(NULL, "timer0"); + + davinci_timer_init(clk); +#else davinci_clk_init(da830_clks); davinci_timer_init(&timerp64_0_clk); +#endif +} + +static struct resource da830_psc0_resources[] = { + { + .start = DA8XX_PSC0_BASE, + .end = DA8XX_PSC0_BASE + SZ_4K - 1, + .flags = IORESOURCE_MEM, + }, +}; + +static struct platform_device da830_psc0_device = { + .name = "da830-psc0", + .id = -1, + .resource = da830_psc0_resources, + .num_resources = ARRAY_SIZE(da830_psc0_resources), +}; + +static struct resource da830_psc1_resources[] = { + { + .start = DA8XX_PSC1_BASE, + .end = DA8XX_PSC1_BASE + SZ_4K - 1, + .flags = IORESOURCE_MEM, + }, +}; + +static struct platform_device da830_psc1_device = { + .name = "da830-psc1", + .id = -1, + .resource = da830_psc1_resources, + .num_resources = ARRAY_SIZE(da830_psc1_resources), +}; + +void __init da830_register_clocks(void) +{ + /* PLL is registered in da830_init_time() */ + platform_device_register(&da830_psc0_device); + platform_device_register(&da830_psc1_device); } diff --git a/arch/arm/mach-davinci/include/mach/da8xx.h b/arch/arm/mach-davinci/include/mach/da8xx.h index 9fd6d0125762..64861ac6a9d4 100644 --- a/arch/arm/mach-davinci/include/mach/da8xx.h +++ b/arch/arm/mach-davinci/include/mach/da8xx.h @@ -89,6 +89,7 @@ extern unsigned int da850_max_speed; void da830_init(void); void da830_init_time(void); +void da830_register_clocks(void); void da850_init(void); void da850_init_time(void);
