// dear imgui: Platform Binding for Windows (standard windows API for 32 and 64 bits applications)
// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)

// Implemented features:
//  [X] Platform: Clipboard support (for Win32 this is actually part of core imgui)
//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
//  [X] Platform: Keyboard arrays indexed using VK_* Virtual Key Codes, e.g. ImGui::IsKeyPressed(VK_SPACE).
// Missing features:
//  [ ] Platform: Gamepad support (best leaving it to user application to fill io.NavInputs[] with gamepad inputs from their source of choice).

IMGUI_IMPL_API bool     ImGui_ImplWin32_Init(void* hwnd);
IMGUI_IMPL_API void     ImGui_ImplWin32_Shutdown();
IMGUI_IMPL_API void     ImGui_ImplWin32_NewFrame();

// Handler for Win32 messages, update mouse/keyboard data.
// You may or not need this for your implementation, but it can serve as reference for handling inputs.
// Intentionally commented out to avoid dragging dependencies on <windows.h> types. You can copy the extern declaration in your code.

bcm2709: Drop platform smp and timer init code

irq-bcm2836 handles this through these functions:
bcm2835_init_local_timer_frequency()
bcm2836_arm_irqchip_smp_init()

Signed-off-by: Noralf Trønnes <noralf@tronnes.org>

bcm270x: Use watchdog for reboot/poweroff

The watchdog driver already has support for reboot/poweroff.
Make use of this and remove the code from the platform files.
