From: Mark Grosen <[email protected]> Add davinci remoteproc device for the da850's C674x dsp remote processor, and support it on the da850-evm and omapl138-hawk boards.
Signed-off-by: Mark Grosen <[email protected]> Signed-off-by: Ohad Ben-Cohen <[email protected]> --- It'd be nice to split this patch to the different components it changes, but it's probably not so important at this early stage. arch/arm/mach-davinci/board-da850-evm.c | 4 ++++ arch/arm/mach-davinci/board-omapl138-hawk.c | 4 ++++ arch/arm/mach-davinci/da850.c | 14 ++++++++++++++ arch/arm/mach-davinci/devices-da8xx.c | 15 +++++++++++++++ arch/arm/mach-davinci/include/mach/da8xx.h | 1 + 5 files changed, 38 insertions(+), 0 deletions(-) diff --git a/arch/arm/mach-davinci/board-da850-evm.c b/arch/arm/mach-davinci/board-da850-evm.c index a7b41bf..6b35f0a 100644 --- a/arch/arm/mach-davinci/board-da850-evm.c +++ b/arch/arm/mach-davinci/board-da850-evm.c @@ -1176,6 +1176,10 @@ static __init void da850_evm_init(void) i2c_register_board_info(1, da850_evm_i2c_devices, ARRAY_SIZE(da850_evm_i2c_devices)); + ret = da850_register_rproc(); + if (ret) + pr_warning("dsp/rproc registration failed: %d\n", ret); + /* * shut down uart 0 and 1; they are not used on the board and * accessing them causes endless "too much work in irq53" messages diff --git a/arch/arm/mach-davinci/board-omapl138-hawk.c b/arch/arm/mach-davinci/board-omapl138-hawk.c index 67c38d0..52c8434 100644 --- a/arch/arm/mach-davinci/board-omapl138-hawk.c +++ b/arch/arm/mach-davinci/board-omapl138-hawk.c @@ -319,6 +319,10 @@ static __init void omapl138_hawk_init(void) pr_warning("omapl138_hawk_init: " "watchdog registration failed: %d\n", ret); + + ret = da850_register_rproc(); + if (ret) + pr_warning("dsp/rproc registration failed: %d\n", ret); } #ifdef CONFIG_SERIAL_8250_CONSOLE diff --git a/arch/arm/mach-davinci/da850.c b/arch/arm/mach-davinci/da850.c index 133aac4..9280b1e 100644 --- a/arch/arm/mach-davinci/da850.c +++ b/arch/arm/mach-davinci/da850.c @@ -74,6 +74,13 @@ static struct clk pll0_aux_clk = { .flags = CLK_PLL | PRE_PLL, }; +static struct clk pll0_sysclk1 = { + .name = "pll0_sysclk1", + .parent = &pll0_clk, + .flags = CLK_PLL, + .div_reg = PLLDIV1, +}; + static struct clk pll0_sysclk2 = { .name = "pll0_sysclk2", .parent = &pll0_clk, @@ -373,6 +380,12 @@ static struct clk spi1_clk = { .flags = DA850_CLK_ASYNC3, }; +static struct clk dsp_clk = { + .name = "dsp", + .parent = &pll0_sysclk1, + .lpsc = DA8XX_LPSC0_GEM, +}; + static struct clk_lookup da850_clks[] = { CLK(NULL, "ref", &ref_clk), CLK(NULL, "pll0", &pll0_clk), @@ -419,6 +432,7 @@ static struct clk_lookup da850_clks[] = { CLK(NULL, "usb20", &usb20_clk), CLK("spi_davinci.0", NULL, &spi0_clk), CLK("spi_davinci.1", NULL, &spi1_clk), + CLK(NULL, "dsp", &dsp_clk), CLK(NULL, NULL, NULL), }; diff --git a/arch/arm/mach-davinci/devices-da8xx.c b/arch/arm/mach-davinci/devices-da8xx.c index fc4e98e..3becfd1 100644 --- a/arch/arm/mach-davinci/devices-da8xx.c +++ b/arch/arm/mach-davinci/devices-da8xx.c @@ -20,6 +20,7 @@ #include <mach/time.h> #include <mach/da8xx.h> #include <mach/cpuidle.h> +#include <mach/remoteproc.h> #include "clock.h" @@ -647,6 +648,20 @@ int __init da850_register_mmcsd1(struct davinci_mmc_config *config) da850_mmcsd1_device.dev.platform_data = config; return platform_device_register(&da850_mmcsd1_device); } + +int __init da850_register_rproc(void) +{ + struct platform_device *rproc; + struct davinci_rproc_pdata rproc_pdata = { + .name = "dsp", + .firmware = "davinci-dsp.bin", + .clk_name = "dsp", + }; + + rproc = platform_device_register_data(NULL, "davinci-rproc", 0, + &rproc_pdata, sizeof(rproc_pdata)); + return PTR_RET(rproc); +}; #endif static struct resource da8xx_rtc_resources[] = { diff --git a/arch/arm/mach-davinci/include/mach/da8xx.h b/arch/arm/mach-davinci/include/mach/da8xx.h index ad64da7..a6f024f 100644 --- a/arch/arm/mach-davinci/include/mach/da8xx.h +++ b/arch/arm/mach-davinci/include/mach/da8xx.h @@ -74,6 +74,7 @@ void __init da850_init(void); int da830_register_edma(struct edma_rsv_info *rsv); int da850_register_edma(struct edma_rsv_info *rsv[2]); +int da850_register_rproc(void); int da8xx_register_i2c(int instance, struct davinci_i2c_platform_data *pdata); int da8xx_register_spi(int instance, struct spi_board_info *info, unsigned len); int da8xx_register_watchdog(void); -- 1.7.1 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
