-/**
- * .doc : 对 sysfs_dir_of_mali_device 下 rk_ext_file_nodes 提供的接口的定义
- *
- * sysfs_dir_of_mali_device 通常是 sys/devices/ffa30000.gpu
- *
- * 其下有如下的 rk_ext_file_nodes :
- * clock,
- * 对该文件的 cat 操作, 将输出当前 gpu_clk_freq 和可能的 freq 的列表, 形如 :
- * current_gpu_clk_freq : 99000 KHz
- * possible_freqs : 99000, 179000, 297000, 417000, 480000 (KHz)
- * 出现在 "possible_freqs" 中的有效频点, 依赖在 .dts 文件中的配置.
- * 可以使用 echo 命令向本文件写入待设置的 gpu_clk_freq_in_khz, 比如 :
- * echo 417000 > clock
- * 注意, 这里写入的 gpu_clk_freq_in_khz "必须" 是出现在 possible_freqs 中的.
- * 另外, mali_module 默认使能 dvfs,
- * 所以若希望将 gpu_clk 固定在上面的特定 freq, 要关闭 dvfs 先 :
- * echo off > dvfs
- * fbdev,
- * 只支持 cat.
- * .R : 目前不确定该提供接口的用意.
- * // dtlb,
- * dvfs,
- * cat 该节点, 将返回当前 mali_dvfs 的状态, 包括 mali_dvfs 是否开启, gpu 使用率, 当前 gpu_clk 频率.
- * 若当前 mali_dvfs 被开启, 可能返回如下信息 :
- * mali_dvfs is ON
- * gpu_utilisation : 100
- * current_gpu_clk_freq : 480 MHz
- * 若当前 mali_dvfs 被关闭, 可能返回 :
- * mali_dvfs is OFF
- * current_gpu_clk_freq : 99 MHz
- * 若一段时间没有 job 下发到 gpu, common_parts 也会自动关闭 mali_dvfs.
- *
- * 将字串 off 写入该节点, 将关闭 mali_dvfs,
- * 且会将 gpu_clk_freq 固定到可能的最高的频率 或者 gpu_clk_freq_of_upper_limit(若有指定).
- * 之后, 若将字串 on 写入该节点, 将重新开启 mali_dvfs.
- *
- * dvfs_upper_lock,
- * cat 该节点, 返回当前 dvfs_level_upper_limit 的信息, 诸如
- * upper_lock_freq : 417000 KHz
- * possible upper_lock_freqs : 99000, 179000, 297000, 417000, 480000 (KHz)
- * if you want to unset upper_lock_freq, to echo 'off' to this file.
- *
- * 对该节点写入上面 possible upper_lock_freqs 中的某个 频率, 可以将该频率设置为 gpu_clk_freq_of_upper_limit, 比如.
- * echo 417000 > dvfs_upper_lock
- * 若要清除之前设置的 dvfs_level_upper_limit, 写入 off 即可.
- *
- * dvfs_under_lock,
- * cat 该节点, 返回当前 dvfs_level_lower_limit 的信息, 诸如
- * under_lock_freq : 179000 KHz
- * possible under_lock_freqs : 99000, 179000, 297000, 417000, 480000 (KHz)
- * if you want to unset under_lock_freq, to echo 'off' to this file.
- * 对该节点写入上面 possible under_lock_freq 中的某个 频率, 可以将该频率设置为 gpu_clk_freq_of_lower_limit, 比如.
- * echo 179000 > dvfs_under_lock
- * 若要清除之前设置的 dvfs_level_lower_limit, 写入 off 即可.
- *
- * time_in_state
- * cat 该节点, 返回 mali_dvfs 停留在不同 level 中的时间统计, 譬如
- * ------------------------------------------------------------------------------
- * index_of_level gpu_clk_freq (KHz) time_in_this_level (s)
- * ------------------------------------------------------------------------------
- * 0 99 206
- * 1 179 9
- * 2 297 0
- * 3 417 0
- * 4 480 47
- * ------------------------------------------------------------------------------
- * 若通过 dvfs 节点, 开启/关闭 mali_dvfs, 则本节点输出的信息可能不准确.
- *
- * 若要复位上述时间统计, 可以向该节点写入任意字串, 比如 :
- * echo dummy > time_in_state
