Linux-2.6.32 内核LCD驱动移植

分类： 嵌入式

2014-07-10 21:47:08

本移植主要参考友善之臂移植手册完成，做个笔记以备不时之需
Linux-2.6.32 内核LCD驱动移植
使用环境：fedora9
交叉编译工具链：arm-linux-gcc-4.4.3
内核源码来源：
内核存放目录：/opt/mymini2440/linux-2.6.32

一、LCD背光驱动移植
在、opt/mymini2440/linux-2.6.32/drivers/video/目录下添加背光驱动程序mini2440_backlight.c，内容如下：
  1. //以下头文件可能并不是每一个都必须的，但多余的并不会影响驱动程序的内容
  2. #include <linux/errno.h>
  3. #include <linux/kernel.h>
  4. #include <linux/module.h>
  5. #include <linux/slab.h>
  6. #include <linux/input.h>
  7. #include <linux/init.h>
  8. #include <linux/serio.h>
  9. #include <linux/delay.h>
  10. #include <linux/clk.h>
  11. #include <linux/miscdevice.h>
  12. #include <linux/gpio.h>
  13. #include <asm/io.h>
  14. #include <asm/irq.h>
  15. #include <asm/uaccess.h>
  16. #include <mach/regs-clock.h>
  17. #include <plat/regs-timer.h>
  18. #include <mach/regs-gpio.h>
  19. #include <linux/cdev.h>
  20. #undef DEBUG
  21. //#define DEBUG
  22. #ifdef DEBUG
  23. #define DPRINTK(x...) {printk(__FUNCTION__"(%d): ",__LINE__);printk(##x);}
  24. #else
  25. #define DPRINTK(x...) (void)(0)
  26. #endif
  27. //定义背光驱动的名称为backligh，将会出现在/dev/backlight
  28. #define DEVICE_NAME "backlight"
  29. //定义背光变量bl_state，以记录背光的开关状态
  30. static unsigned int bl_state;
  31. //设置背光开关的函数，主要是翻转背光变量bl_state
  32. static inline void set_bl(int state)
  33. {
  34. bl_state = !!state; //翻转bl_state 变量
  35. s3c2410_gpio_setpin(S3C2410_GPG(4), bl_state); //把结果写入背光所用的寄存器GPG4
  36. }
  37. //获取背光状态
  38. static inline unsigned int get_bl(void)
  39. {
  40. return bl_state;
  41. }
  42. //从应用程序读取参数，并传递到内核中
  43. static ssize_t dev_write(struct file *file, const char *buffer, size_t count, loff_t * ppos)
  44. {
  45. unsigned char ch;
  46. int ret;
  47. if (count == 0) {
  48. return count;
  49. }
  50. //使用copy_from_user 函数从用户层/应用层读取参数
  51. ret = copy_from_user(&ch, buffer, sizeof ch) ? -EFAULT : 0;
  52. if (ret) {
  53. return ret;
  54. }
  55. ch &= 0x01; //判断奇数还是偶数
  56. set_bl(ch); //设置背光状态
  57. return count;
  58. }
  59. //把内核参数传递给用户层/应用层的读函数
  60. static ssize_t dev_read(struct file *filp, char *buffer, size_t count, loff_t *ppos)
  61. {
  62. int ret;
  63. unsigned char str[] = {'0', '1' };
  64. if (count == 0) {
  65. return 0;
  66. }
  67. //使用copy_to_user 函数把内核参数传递到用户层/应用层
  68. ret = copy_to_user(buffer, str + get_bl(), sizeof(unsigned char) ) ? -EFAULT : 0;
  69. if (ret) {
  70. return ret;
  71. }
  72. return sizeof(unsigned char);
  73. }
  74. //设备操作集
  75. static struct file_operations dev_fops = {
  76. owner: THIS_MODULE,
  77. read:dev_read,
  78. write: dev_write,
  79. };
  80. static struct miscdevice misc = {
  81. .minor = MISC_DYNAMIC_MINOR,
  82. .name = DEVICE_NAME,
  83. .fops = &dev_fops,
  84. };
  85. //设备初始化，内核启动时就有效
  86. static int __init dev_init(void)
  87. {
  88. int ret;
  89. ret = misc_register(&misc);
  90. printk (DEVICE_NAME"\tinitialized\n");
  91. //初始化背光所用的端口GPG4 为输出
  92. s3c2410_gpio_cfgpin(S3C2410_GPG(4), S3C2410_GPIO_OUTPUT);
  93. //启动内核时打开背光
  94. set_bl(1);
  95. return ret;
  96. }
  97. static void __exit dev_exit(void)
  98. {
  99. misc_deregister(&misc);
  100. }
  101. module_init(dev_init); //注册背光驱动模块
  102. module_exit(dev_exit); //卸载背光驱动模块
  103. MODULE_LICENSE("GPL");
  104. MODULE_AUTHOR("FriendlyARM Inc.");
在/opt/mymini2440/linux-2.6.32/drivers/video/目录项的菜单文件Kconfig中添加LCD背光驱动配置菜单如下：

  1. config FB_S3C2410_DEBUG
  2. bool "S3C2410 lcd debug messages"
  3. depends on FB_S3C2410
  4. help
  5. Turn on debugging messages. Note that you can set/unset at run time
  6. through sysfs

  8. config BACKLIGHT_MINI2440
  9. tristate "Backlight support for mini2440 from FriendlyARM"
  10. depends on MACH_MINI2440 && FB_S3C2410
  11. help
  12. backlight driver for MINI2440 from FriendlyARM

  14. config FB_SM501
  15. tristate "Silicon Motion SM501 framebuffer support"
在/opt/mymini2440/linux-2.6.32/drivers/video/Makefile中添加背光驱动目标文件
  1. # the test framebuffer is last
  2. obj-$(CONFIG_FB_VIRTUAL) += vfb.o
  3. #video output switch sysfs driver
  4. obj-$(CONFIG_VIDEO_OUTPUT_CONTROL) += output.o
  5. obj-$(CONFIG_BACKLIGHT_MINI2440) += mini2440_backlight.o
配置内核：
Device Drivers  ---> Graphics support --->  <*> Support for frame buffer devices          
    ---> <*>   Backlight support for mini2440 from FriendlyARM 
背光驱动移植完毕！
二、LCD驱动移植
在内核中添加各种LCD 类型的支持（我是X35的屏，也是我只需关注的部分，不过还是都添加了，X35有红色标出）
删除mach-mini2440.c原有代码（本人115行-158行）

然后打开drivers/video/Kconfig，在大概1935 行加入以下配置信息：

LCD驱动移植完成！！！
三、开机logo和开机信息显示
Device Drivers  --->  Graphics support  --->  <*> Support for frame buffer devices  ---> [*] Bootup logo  --->  [*]   Standard 16-color Linux logo （本人的24位死活不能显示，先改成16位吧）
在文件系统rootfs/etc/inittab下作如下修改（为了在LCD上显示打印信息）：
  1. 1 ::sysinit:/etc/init.d/rcS
  2.   2 tty1::askfirst:-/bin/sh    //添加
  3.   3 s3c2410_serial0::askfirst:-/bin/sh
  4.   4 ::ctrlaltdel:/sbin/reboot
  5.   5 ::shutdown:/bin/umount -a -r
  6.   6
四，编译测试
#make zImage
#cd arch/arm/boot/
#mkimage -n 'mini2440_linux' -A arm -O linux -T kernel -C none -a 0x31000000 -e 0x31000040 -d zImage uImage
#chmod a+x uImage 
#cp uImage /tftp/boot
设置U-BOOT参数如下：

  1. [u-boot]# printenv
  2. bootdelay=1
  3. baudrate=115200
  4. ethaddr=08:08:11:18:12:27
  5. ipaddr=10.50.80.1
  6. serverip=10.50.80.207
  7. gatewayip=10.50.80.207
  8. netmask=255.255.254.0
  9. tekkaman=bmp d 70000
  10.  stdin=serial
  11. stdout=serial
  12. stderr=serial
  13. ethact=dm9000
