I found that if use mutex in `rt_kprintf`,
the `rt_enter_critical` will create a assert
error later. after chehcking,I found all
operation with fd_table has using
`dfs_lock/unlock` to protect. so I think
using `dfs_lock` is enough. thanks.

修改SD检测线程函数里面的延时实现,将mmcsd_delay_ms改为rt_thread_mdelay. mmcsd_delay_ms过时且延时计算错误。

如果打印格式为"%02X"的数据大于0x7F,打印的数据就会在前面多出6个'F',原因详见https://blog.csdn.net/zqxwce821/article/details/53011925。
现在通过强制转换成unsigned char后,在STM32(KEIL5+C99)已测试确认能修复该问题。

1. 在c28x文件目录上一层再套一层文件夹ti,目前28379的项目路径为rt-thread\bsp\ti\c28x\tms320f28379d
2. 新增adc驱动与kconfig配置

�要调用dfs_file_lseek()函数,直接返回当前位置即可。 (#6498)
当seek到文件的位置和当前位置相同时,不需要调用dfs_file_lseek()函数,直接返回当前位置即可。
同时,以lseek(fd,0,SEEK_CUR)的方式执行函数可以返回文件当前读去位置,可以实现
ftell()的功能.
以lseek(fd,0,SEEK_CUR)的方式执行函数返回文件当前位置,实现ftell()的功能时不用调用dfs_file_lseek()函数,提高效率;seek(fd,0,SEEK_CUR)本来就能返回当前位置。

增加c28x芯片的pwm驱动
已经在TMS320F28379中通过测试
pwm设备框架增加如下方法:
#define PWM_CMD_SET_DEAD_TIME (RT_DEVICE_CTRL_BASE(PWM) + 8)
#define PWM_CMD_SET_PHASE (RT_DEVICE_CTRL_BASE(PWM) + 9)
#define PWM_CMD_ENABLE_IRQ (RT_DEVICE_CTRL_BASE(PWM) + 10)
#define PWM_CMD_DISABLE_IRQ (RT_DEVICE_CTRL_BASE(PWM) + 11)

版本控制规范:https://semver.org/
目前的版本子号不是很规范,其中RT_VERSION甚至和VS那边造成了冲突
```c
/* RT-Thread version information */
#define RT_VERSION 4L /**< major version number */
#define RT_SUBVERSION 1L /**< minor version number */
#define RT_REVISION 1L /**< revise version number */
```
参考ESP32:
```c
/** Major version number (X.x.x) */
#define ESP_ARDUINO_VERSION_MAJOR 2
/** Minor version number (x.X.x) */
#define ESP_ARDUINO_VERSION_MINOR 0
/** Patch version number (x.x.X) */
#define ESP_ARDUINO_VERSION_PATCH 3
```
建议改成:
```c
/* Major version number (X.x.x) */
#define RT_VERSION_MAJOR 4
/* Minor version number (x.X.x) */
#define RT_VERSION_MINOR 2
/* Patch version number (x.x.X) */
#define RT_VERSION_PATCH 0
```

弊之后得到的一套解决方案。Keil曾经提供了底层桩函数_sys_ensure,但是目前已经被废弃。因此唯一的解决方案就是每写完一句,就调用fsync去同步一次。
该问题在mbedos社区也进行过讨论,他们也面临和我们相同的两个问题:
1. Keil-MDK无有效的fflush解决方案,mbedos依然在使用淘汰的_sys_ensure桩函数。
2. Keil-MDK没有fileno函数,我方少部分软件包因此而无法使用Keil平台编译。
参考:https://github.com/ARMmbed/mbed-os/issues/1601
issue: https://github.com/RT-Thread/rt-thread/issues/4928
经过进一步测试发现,Keil-MDK中的fflush函数已经退化成服务于STDOUT的函数,Keil-MDK内部有一个buffer可以存放fputc(stdout) 发过来的数据,如果调用fflush,这些数据是可以flush出去的。但是如果是真正的文件数据,fflush函数并没有提供任何桩函数接口可以让文件flush数据出去。

- in _can_int_tx if can driver sendmsg do not return RT_EOK,
it will repeat until sendmsg return RT_EOK
- if error occur on can bus(wire broken or EMI), all threads that
have lower priority will not be executed
- we should let application layer to determine if resend is appropriate
when send fail, besides in data link layer, can already implemented
auto resend in hardware
