Hello all,



I have tried to communicate MCP2515 with new kernel 3.14-rc2 using DTS. At 
this version, the driver has been modified to support DTS structures.

The hardware its ok, because it has worked witk linux 2.6.39.

The SPI controller also it's ok, because I have an AT45DB321 connected and 
its detected.

Could somebody give some tips?




My DTS SPI node:


			spi0: spi@f0000000 {

				status = "okay";

				interrupts = <13 4 5>;

				cs-gpios = <&pioA 14 0>, <&pioA 7 0>, <&pioA 1 0>, <0>; /* CHIP SELECT */

       			

        			

				mtd_dataflash@0 {

					compatible = "atmel,at45", "atmel,dataflash";

					spi-max-frequency = <1000000>;

					reg = <0>;

				};

				

				can0: can@1 {

					compatible = "microchip,mcp2515";

					reg = <2>;

					spi-max-frequency = <5000000>;

					clocks = <&mcp251x_clock>;

					interrupt-parent = <&pioC>; /* MCP GPO Interrupt */

					interrupts = <12 0x2>;

				};

		};



I have seen that the mcp2515 interrupt was not created.

Hi again,


I found the causes of problem, and now I need to know if I was setting 
wrong structure or there are driver problem.
I've had this modification on mcp251x.c:

static int mcp251x_can_probe(struct spi_device *spi)
{
     const struct of_device_id *of_id = of_match_device(mcp251x_of_match,
                                &spi->dev);
     struct mcp251x_platform_data *pdata = dev_get_platdata(&spi->dev);
     struct net_device *net;
     struct mcp251x_priv *priv;
     int freq, ret = -ENODEV;
     struct clk *clk;


     clk = devm_clk_get(&spi->dev, NULL);
     dev_dbg(&spi->dev, "MCP2515: clk = devm_clk_get(&spi->dev, NULL)");
     if (IS_ERR(clk)) {
         if (pdata)
         {
             freq = pdata->oscillator_frequency;
         }
         else
         {
 >>        freq = 20 * 1000 * 1000;    // FORCE FREQUENCY to 20Mhz
             //return PTR_ERR(clk);
         }
     } else {
         dev_dbg(&spi->dev, "MCP2515: freq = clk_get_rate(clk);");
         freq = clk_get_rate(clk);
     }


Then the driver start to run.

I think that the problem is about how to set a correct clock.


I put on can node:
                 can0: can@1 {
                     compatible = "microchip,mcp2515";
                     reg = <2>;
                     spi-max-frequency = <5000000>;
                     clocks = <&mcp251x_clock>;
                     interrupt-parent = <&pioC>; /* MCP GPO Interrupt */
                     interrupts = <12 0x2>;
                 };



and my clocks node:

     clocks {
         #address-cells = <1>;
         #size-cells = <1>;
         ranges;

         main_clock: clock@0 {
             compatible = "atmel,osc", "fixed-clock";
             clock-frequency = <12000000>;
         };

         mcp251x_clock: mcp2515 {
             compatible = "fixed-clock";
             #clock-cells = <0>;
             clock-frequency = <20000000>;
         };


     };


So... How can we know if it's a DTS definition or a driver problem?




regards,



Lucas Zampar

The driver looks good. I've put Alexander Shiyan, who contributed the DT
pachtes, on Cc. Maybe he can post the DT he used.

can0 ... can@1 ... reg = <2>...
Uhhh....

Unfortunately I do not see the original message, please repeat it to me.
Boot log is also required, as long as I do not understand what the problem
you have there.

Hello Alexander,


Follow attach my DTS file and my dmesg log.
How you can see, we have "mcp251x: probe of spi32766.2 failed with error 
-2.".
I discovered that the cause is the clock config structure, because if 
I've forced a frequency hardcode all driver works.
The point where I've forced is:

on mcp251x.c

static int mcp251x_can_probe(struct spi_device *spi)
{
     const struct of_device_id *of_id = of_match_device(mcp251x_of_match,
                                &spi->dev);
     struct mcp251x_platform_data *pdata = dev_get_platdata(&spi->dev);
     struct net_device *net;
     struct mcp251x_priv *priv;
     int freq, ret = -ENODEV;
     struct clk *clk;

     clk = devm_clk_get(&spi->dev, NULL);
     if (IS_ERR(clk)) {
         if (pdata)
             freq = pdata->oscillator_frequency;
         else
             freq = 20 * 1000 * 1000;  /* crystal freq HARDCODE */
            // return PTR_ERR(clk);
     } else {
         freq = clk_get_rate(clk);
     }
....


I'm really don't know if it's a dts config problem or a driver problem.




regards,


Lucas

Seems, you are missing "fixed-clock" driver in the kernel.
Is CONFIG_COMMON_CLK option is enabled in your .config?

You are right Alexander!
The CONFIG_COMMON_CLK hasn't enable!
But for all SOC AT91_SAM9x5 still uses old clock style (AT91_USE_OLD_CLK):

config SOC_AT91SAM9X5
         bool "AT91SAM9x5 family"
         select HAVE_AT91_DBGU0
         select HAVE_FB_ATMEL
         select SOC_AT91SAM9
         select AT91_USE_OLD_CLK
         select HAVE_AT91_UTMI
         select HAVE_AT91_SMD
         select HAVE_AT91_USB_CLK

and one of dependencies for COMMON_CLK_AT91 is don't be AT91_USE_OLD_CLK

config COMMON_CLK_AT91
         bool
        default AT91_PMC_UNIT && USE_OF && !AT91_USE_OLD_CLK
         select COMMON_CLK

config OLD_CLK_AT91
         bool
         default AT91_PMC_UNIT && AT91_USE_OLD_CLK




Now came my question: Can I use CONFIG_COMMON_CLK without my ARCH 
support? If not, how we will support devices that need CONFIG_COMMON_CLK?



regards,


Lucas

You probably have to wait for common clock support. However you can
still hook platform data to your spi device. For a mxs add this to
arch/arm/mach-mxs/mach-mxs.c:

static int abc_spi_notifier_call(struct notifier_block *nb,
					unsigned long event, void *data)
{
	struct device *dev = data;

	if (event == BUS_NOTIFY_BIND_DRIVER)
		if (strcmp(dev_name(dev), "spi32766.0") == 0)
			dev->platform_data = &abc_pdata;

	return NOTIFY_OK;
}

static struct notifier_block abc_spi_nb = {
	.notifier_call = abc_spi_notifier_call,
};

static void __init abc_post_init(void)
{
	bus_register_notifier(&spi_bus_type, &abc_spi_nb);
}

static void __init mxs_machine_init(void)
{

	of_platform_populate(NULL, of_default_bus_match_table,
			     mxs_auxdata_lookup, NULL);

	if (of_machine_is_compatible("123,abc"))
		abc_post_init();
}

Nevertheless, support for the CLK API for SOC AT91_SAM9x5 seems
already in the kernel.
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/drivers/clk/at91/pmc.c?id=05202872ca98f8ea61943a9b530417c5503b816f

You can ask about the CLK status in the AT91 mailing list.

Tnks a lot guys!

I will check for COMMON_CLK support at linux-at91, but for while, I will 
use the hardcode frequency!
