In the serial ISR (`rt_hw_serial_isr`), the previous logic for handling a full RX FIFO was flawed. When the buffer was filled, it would increment `get_index` (`get_index += 1`).
This had two negative consequences:
1. It effectively discarded the oldest byte of data prematurely.
2. It reduced the usable capacity of a buffer of size N to N-1. For example, a 64-byte buffer could only ever hold 63 readable bytes after becoming full.
This patch corrects the behavior by implementing a standard overwriting ring buffer strategy. When the buffer is full, the logic is changed to `get_index = put_index`.
This ensures that:
- When new data arrives, it correctly overwrites the oldest data.
- The `get_index` is advanced along with the `put_index`, correctly marking the new start of the buffer.
- The full N-byte capacity of the buffer is utilized, always storing the N most recent bytes.
This change resolves the unexpected data loss and makes the buffer behavior correct and predictable.

Solution: gd32_uart_gpio_init 不开中断
等驱动框架初始化好fifo后通过 device_control 开中断

issue (#10524)
* Modify the reference path of the header file in the middle section
* format
* Fix smart serial_v2 bypass compile error issue
* add allwinner/d1s ci
|
|
* [bugfix][component/dfs]1.Skip the trailing slash character failed. 2. Scenario that parent path is root is not considered.
* replace strdup() by rt_strdup().
* free memory after strdup().
* fix issue of not appending '\0' at end when parent path is root.

修复CAN底层无法工作时导致调用 _can_int_tx 的线程一直挂起的问题
Solution: 使用 can->status.sndchange 的bit位来表示某个发送邮箱超时
如果超时 底层驱动再通知tx_done或者tx_fail事件时不予处理

Added a PWM driver and a test file test_pwm.c.
The test uses PWM to control the LED brightness,
to check if the driver works correctly.

For "RT-Thread User Guide":
Take the "RT-Thread Kernel Object Model" sub-section out of
the "Kernel Basics" section and rename it to "Object Management".
Correspondingly, rename the "Kernel Object Management" section
in the "RT-Thread API Guide" to "Object Management".

Problen:
Duplicated definition of group_clk in clk.c and clk.h.
Solution:
Delete the definition in clk.c and keep only the definition
in clk.h.
Also change the name of group_clk to group_driver_clock to
conform to the naming convention of other driver groups.

[Fix] <components>:finsh/shell.c
When using char rt_hw_console_getchar(void),
some compilers may default to returning 255 instead of the expected -1,
causing the condition if(ch < 0) at F: shell.c L:519 to fail and enter an erroneous loop.
Solution: Use the signed char type return value as rt_hw_console_getchar
