+# TG5050 Platform (Trimui Smart Pro S)
+
+This document describes the hardware and software requirements for supporting the Trimui Smart Pro S (TG5050) device.
+
+## Overview
+
+| Property  | Value                                        |
+| --------- | -------------------------------------------- |
+| Device    | Trimui Smart Pro S                           |
+| Model ID  | TG5050                                       |
+| SoC       | Allwinner A523 (sun55iw3)                    |
+| CPU       | 8x Cortex-A55 (dual cluster: cpu0-3, cpu4-7) |
+| Display   | 1280x720, DSI panel                          |
+| Toolchain | `tg5040` (shared with Smart Pro)             |
+
+**Important:** Despite sharing the same form factor and toolchain as the Smart Pro (TG5040/T527), the Smart Pro S uses completely different hardware (A523 SoC) with different drivers and control interfaces.
+
+## Hardware Detection
+
+### Device Identification
+
+The device can be identified by checking the MainUI binary:
+
+```bash
+# Check for TG5050
+if strings /usr/trimui/bin/MainUI | grep -q "TG5050"; then
+    DEVICE="tg5050"
+fi
+```
+
+Or by reading the hardware serial:
+
+```bash
+cat /sys/class/sunxi_info/sys_info | grep hwserial
+# Returns: TG5050XXXXXXXXXX
+```
+
+### SoC Identification
+
+```bash
+cat /sys/firmware/devicetree/base/compatible
+# Returns: allwinner,a523 arm,sun55iw3p1
+```
+
+## Display
+
+### Backlight Control
+
+Uses standard sysfs backlight interface (NOT `/dev/disp` ioctl):
+
+```bash
+# Path
+/sys/class/backlight/backlight0/brightness
+
+# Range: 0-255 (stock OS clamps to 10-220)
+echo 128 > /sys/class/backlight/backlight0/brightness
+```
+
+### Display Enhancement (optional)
+
+```bash
+/sys/devices/virtual/disp/disp/attr/enhance_contrast    # 0-100
+/sys/devices/virtual/disp/disp/attr/enhance_saturation  # 0-100
+/sys/devices/virtual/disp/disp/attr/enhance_bright      # 0-100 (exposure)
+/sys/devices/virtual/disp/disp/attr/color_temperature   # color temp adjustment
+```
+
+### Screen Rotation
+
+DSI panel rotation (if needed):
+
+```bash
+/sys/class/drm/card0-DSI-1/rotate
+```
+
+## Audio
+
+### ALSA Mixer Controls
+
+The A523 uses different mixer control names than T527:
+
+| Control      | Purpose                                                    |
+| ------------ | ---------------------------------------------------------- |
+| `DAC Volume` | Main volume control (use tinyalsa `mixer_ctl_set_percent`) |
+| `HPOUT`      | Headphone output (unmute on init)                          |
+| `SPK`        | Speaker output (unmute on init)                            |
+| `LINEOUTL`   | Line out left (unmute on init)                             |
+| `LINEOUTR`   | Line out right (unmute on init)                            |
+
+### Speaker Mute
+
+Hardware speaker mute via sysfs:
+
+```bash
+# Mute speaker (also stops hissing)
+echo 1 > /sys/class/speaker/mute
+
+# Unmute speaker
+echo 0 > /sys/class/speaker/mute
+```
+
+### Initialization Sequence
+
+```bash
+# Unmute all outputs on init
+amixer sset 'HPOUT' unmute
+amixer sset 'SPK' unmute
+amixer sset 'LINEOUTL' unmute
+amixer sset 'LINEOUTR' unmute
+```
+
+### Volume Control (tinyalsa)
+
+```c
+#include <tinyalsa/mixer.h>
+
+void SetRawVolume(int val) {  // 0-100
+    struct mixer *mixer = mixer_open(0);
+    if (!mixer) return;
+
+    struct mixer_ctl *ctl = mixer_get_ctl_by_name(mixer, "DAC Volume");
+    if (ctl) {
+        mixer_ctl_set_percent(ctl, 0, val);
+    }
+    mixer_close(mixer);
+
+    // Full mute requires sysfs
+    putInt("/sys/class/speaker/mute", val == 0 ? 1 : 0);
+}
+```
+
+### Headphone Jack Detection
+
+```bash
+# TODO: Verify path on actual hardware
+/sys/bus/platform/devices/singleadc-joypad/hp
+```
+
+## CPU Frequency Scaling
+
+> **Note:** CPU scaling is **disabled (no-op)** for initial tg5050 implementation. The dual-cluster architecture requires a broader overhaul to properly support big/little SoC configurations. Use `schedutil` governor and let the kernel handle scaling for now.
+
+### Hardware Reference (for future implementation)
+
+The A523 has two CPU clusters with separate frequency policies:
+
+| Cluster | CPUs | Policy Path                                | Frequency Range |
+| ------- | ---- | ------------------------------------------ | --------------- |
+| Little  | 0-3  | `/sys/devices/system/cpu/cpufreq/policy0/` | 408-1416 MHz    |
+| Big     | 4-7  | `/sys/devices/system/cpu/cpufreq/policy4/` | 408-2160 MHz    |
+
+Available frequencies (big cluster):
+
+```
+408000 672000 840000 1008000 1200000 1344000 1488000 1584000 1680000 1800000 1992000 2088000 2160000
+```
+
+### Current Implementation (No-Op)
+
+```c
+void PLAT_setCPUSpeed(int speed) {
+    (void)speed;  // No-op for now - using schedutil governor
+}
+
+int PLAT_getAvailableCPUFrequencies(int* frequencies, int max_count) {
+    (void)frequencies;
+    (void)max_count;
+    return 0;  // Return 0 to disable auto-CPU scaling
+}
+```
+
+## Input
+
+### Rumble/Vibration
+
+Uses GPIO 236 (different from T527's GPIO 227):
+
+```bash
+# Enable rumble
+echo 1 > /sys/class/gpio/gpio236/value
+
+# Disable rumble
+echo 0 > /sys/class/gpio/gpio236/value
+
+# Set rumble intensity (optional)
+echo <0-65535> > /sys/class/motor/level
+```
+
+### Buttons
+
+Device has L3/R3 (stick click) buttons. Uses `trimui_inputd` for turbo and input remapping.
+
+## Power Management
+
+### Battery Status
+
+```bash
+# Capacity (0-100)
+cat /sys/class/power_supply/axp2202-battery/capacity
+
+# Charging status
+cat /sys/class/power_supply/axp2202-usb/online        # 1 = charger connected
+cat /sys/class/power_supply/axp2202-battery/time_to_full_now  # >0 = charging
+```
+
+### CPU Temperature
+
+```bash
+cat /sys/devices/virtual/thermal/thermal_zone0/temp
+# Returns millidegrees, divide by 1000 for Celsius
+```
+
+### Fan Control
+
+```bash
+# Set fan speed (0-31, or use thermal daemon for auto)
+echo <0-31> > /sys/class/thermal/cooling_device0/cur_state
+```
+
+## Graphics
+
+### OpenGL ES
+
+Request GLES 3.2 context:
+
+```c
+SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3);
+SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 2);
+```
+
+### SDL Hints
+
+```c
+SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "1");
+SDL_SetHint(SDL_HINT_RENDER_DRIVER, "opengl");
+SDL_SetHint(SDL_HINT_FRAMEBUFFER_ACCELERATION, "1");
+```
+
+## Networking
+
+### WiFi Module
+
+Uses `aic8800_fdrv.ko` driver:
+
+```bash
+modprobe aic8800_fdrv.ko
+/etc/wifi/wifi_init.sh start
+```
+
+### Bluetooth
+
+Uses `aic8800_btlpm.ko` driver:
+
+```bash
+modprobe aic8800_btlpm.ko
+hciattach -n ttyAS1 aic &
+/etc/bluetooth/bluetoothd start
+```
+
+## LED Control
+
+### LED Animation Paths
+
+```bash
+/sys/class/led_anim/max_scale           # Global brightness
+/sys/class/led_anim/effect_l            # Left joystick LED
+/sys/class/led_anim/effect_r            # Right joystick LED
+/sys/class/led_anim/effect_m            # Logo LED
+/sys/class/led_anim/effect_duration_*   # Animation speed
+/sys/class/led_anim/effect_rgb_hex_*    # Color (hex)
+```
+
+## Platform Constants
+
+```c
+#define PLATFORM "tg5050"
+#define SDCARD_PATH "/mnt/SDCARD"
+#define FIXED_WIDTH 1280
+#define FIXED_HEIGHT 720
+#define FIXED_PITCH (FIXED_WIDTH * 4)
+
+// Uses tg5040 toolchain
+// #define TOOLCHAIN "tg5040"
+```
