S3c2410pwm driver problem HELP! HELP! HELP!

S3c2410pwm driver problem HELP! HELP! HELP! -- Linux general technology-Linux programming and kernel information. The following is a detailed description. S3c2410 pwm driver problem HELP! HELP! HELP! The s3c2410 timer cannot be started, and the PWM wave does not output
The kernel I used is from linux2.6.14.1.


The initialization of the S3c2410pwm driver is as follows:

S3c2410_gpio_cfgpin (maid, FIG );
S3c2410_gpio_pullup (maid, 1 );
S3c2410_gpio_cfgpin (S3C2410_GPB3, S3C2410_GPB3_TOUT3 );
S3c2410_gpio_pullup (S3C2410_GPB3, 1 );

Writel (readl (S3C2410_TCFG1 )&(~ (0xf <20), S3C2410_TCFG1 );
Writel (readl (s3c2410_t1_0 )&(~ S3c2410_t1__prescaler0_mask), s3c2410_t1_0 );
Writel (readl (s3c2410_t1_0) | (249), s3c2410_t1_0 );
Writel (readl (S3C2410_TCFG1) | (s3c2410_t1_mux2_div8), S3C2410_TCFG1 );
Writel (readl (S3C2410_TCNTB (2 ))&(~ 0 xffff), S3C2410_TCNTB (2 ));

Writel (readl (S3C2410_TCNTB (2) | (45000), S3C2410_TCNTB (2 ));
Writel (readl (S3C2410_TCMPB (2) | (15000), S3C2410_TCMPB (2 ));
Writel (readl (S3C2410_TCNTB (3) | (55000), S3C2410_TCNTB (3 ));
Writel (readl (S3C2410_TCMPB (3) | (25000), S3C2410_TCMPB (3 ));

After the register is initialized, the value in the reread shows that the read value is correct .. However, the subfunction cannot be interrupted, and neither TOUT2 nor TOUT3 has waveform output.
The only response is
: Writel (readl (s3c2410_t1_0 )&(~ S3c2410_t1__prescaler1_mask), s3c2410_t1_0 );
Writel (readl (s3c2410_t1_0) | (20), s3c2410_t1_0 );
This speeds up the kernel timer. The cursor on the LCD runs faster.
However, other timers cannot be enabled ,,
Please give me some advice, and the request_irq function can also be successfully registered, but the interruption cannot be obtained, and it is displayed that there is a problem with the free interruption at exit,
If you reinstall this module, the system prompts that the interruption failed,

Hope you can check it out for me ..
