Pull drm updates from Dave Airlie: "Lots of stuff all over, some new AMD IP support and gang submit support. i915 has further DG2 and Meteorlake pieces, and a bunch of i915 display refactoring. msm has a shrinker rework. There are also a bunch of conversions to use kunit. This has two external pieces, some MEI changes needed for future Intel discrete GPUs. These should be acked by Greg. There is also a cross maintainer shared tree with some backlight rework from Hans in here.

2020-09-08fbdev: radeonfb: use generic power managementVaibhav Gupta3-14/+35
Drivers using legacy PCI power management .suspend()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions, as through the generic framework PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

Fixes commit 42ddb453a0cd ("radeon: Conditionally compile PM code") Before the above mentioned patch, codes between the line number 547 and 2803 were already inside "#ifdef CONFIG_PM" container. Thus, addition of "#if defined(CONFIG_PM)" was not required in the patch. It also affected the "#ifdef CONFIG_PPC_OF" container (line 1943-2510). From the current snapshot of radeon_pm.c, remove: 1434 | #if defined(CONFIG_PM) and, 2213 | #endif This removes the redundant CONFIG_PM directive as well as fixes the CONFIG_PPC (earlier CONFIG_PPC_OF) container.

2020-09-08fbdev: aty128fb: use generic power managementVaibhav Gupta1-17/+34
Drivers should do only device-specific jobs. But in general, drivers using legacy PCI PM framework for .suspend()/.resume() have to manage many PCI PM-related tasks themselves which can be done by PCI Core itself. This brings extra load on the driver and it directly calls PCI helper functions to handle them. Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove unnecessary calls to the PCI Helper functions along with the legacy .suspend & .resume bindings. Now, - aty128_pci_suspend() had a "pm_message_t" type parameter as per legacy PCI PM framework that got deprecated in generic. - Rename the callback as aty128_pci_suspend_late() and preserve the parameter. - Define 3 new callbacks as: * aty128_pci_suspend() * aty128_pci_freeze() * aty128_pci_hibernate() which in turn call aty128_pci_suspend_late() by passing appropriate value for "pm_message_t" type parameter. - Bind the callbacks in "struct dev_pm_ops" type variable "aty128_pci_pm_ops".

Also, remove unnecessary calls to the PCI Helper functions along with the legacy .suspend & .resume bindings. Now, - atyfb_pci_suspend() had a "pm_message_t" type parameter as per legacy PCI PM framework, that got deprecated in generic. - Rename the callback as atyfb_pci_suspend_late() and preserve the parameter. - Define 3 new callbacks as: * atyfb_pci_suspend() * atyfb_pci_freeze() * atyfb_pci_hibernate() which in turn call atyfb_pci_suspend_late() by passing appropriate value for "pm_message_t" type parameter. - Bind the callbacks in "struct dev_pm_ops" type variable "atyfb_pci_pm_ops".

2019-12-05video: constify fb ops across all driversJani Nikula2-2/+2
Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com

2019-06-28video: fbdev: don't print error message on framebuffer_alloc() failureBartlomiej Zolnierkiewicz3-11/+6
framebuffer_alloc() can fail only on kzalloc() memory allocation failure and since kzalloc() will print error message in such case we can omit printing extra error message in drivers (which BTW is what the majority of framebuffer_alloc() users is doing already).

2019-06-12fbdev/aty128fb: Remove dead codeDaniel Vetter1-64/+0
Motivated because it contains a struct display, which is a fbcon internal data structure that I want to rename. It seems to have been formerly used in drivers, but that's very long time ago.
