2021-08-10drm: Remove unused devm_drm_irq_install()Thomas Zimmermann2-33/+0
DRM IRQ helpers will become legacy. The function devm_drm_irq_install() is unused and won't be required later. Signed-off-by: Thomas Zimmermann <[email protected]> Acked-by: Sam Ravnborg <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2021-08-10drm/vc4: Convert to Linux IRQ interfacesThomas Zimmermann4-24/+53
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.

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.

Until now, the compute function either stored plain values or register bits in struct mgag200_pll_values. The rsp update function used the values as-is.

2021-08-08drm/mgag200: Split PLL setup into compute and update functionsThomas Zimmermann2-52/+198
The _set_plls() functions compute a pixel clock's PLL values and program the hardware accordingly. This happens during atomic commits. For atomic modesetting, it's better to separate computation and programming from each other. This will allow to compute the PLL value during atomic checks and catch unsupported modes early. Split the PLL setup into a compute and an update functions, and call them one after the other. Computed PLL values are store in struct mgag200_pll_values. There are four parameters for the PLL, m, n, p and s. Every compute function stores a value for each of these parameters, and the rsp update function makes the register bits from them. The values stored by the compute function are either plain values or register bits. An additional change is required to always store plain values. No functional changes.

2021-08-05drm: add lockdep assert to drm_is_current_master_lockedDesmond Cheong Zhi Xi2-3/+7
In drm_is_current_master_locked, accessing drm_file.master should be protected by either drm_file.master_lookup_lock or drm_device.master_mutex. This was previously awkward to assert with lockdep. Following patch ("locking/lockdep: Provide lockdep_assert{,_once}() helpers"), this assertion is now convenient. So we add in the assertion and explain this lock design in the kerneldoc.
