<title>drm/tilcdc: Convert to Linux IRQ interfaces</title>

<content type='text'>
Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's
IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers
don't benefit from using it.

DRM IRQ callbacks are now being called directly or inlined.

Calls to platform_get_irq() can fail with a negative errno code.
Abort initialization in this case. The DRM IRQ midlayer does not
handle this case correctly.

For most drivers, only the DRM IRQ helpers use irq_enabled from
struct drm_device. Tilcdc also uses irq_enabled to make its error
rollback work correctly. As the field will become legacy, duplicated
the state in the driver's local private structure.

Being informed of a failure to attach a bridge is useful, and many

The tilcdc_pclk_diff() compares the requested pixel clock rate to the
real one, so passing it clk_rate instead of clk_rate / clkdiv caused
it to fail even if the clk_rate was properly set. Adding the
real_pclk_rate variable makes the code more readable.

Many drivers reference the plane-&gt;state pointer in order to get the
current plane state in their atomic_update or atomic_disable hooks,
which would be the new plane state in the global atomic state since
_swap_state happened when those hooks are run.

Use the drm_atomic_get_new_plane_state helper to get that state to make it
more obvious.

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.

The conversion was done using the coccinelle script below, built tested on
all the drivers.

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.

The conversion was done using the coccinelle script below, built tested on
all the drivers.
