674dc7f6 - drm/panthor: Fix undefined panthor_device_suspend/resume symbol issue

drm/panthor: Fix undefined panthor_device_suspend/resume symbol issuepanthor_device_resume/suspend() are only compiled when CONFIG_PM isenabled but panthro_drv.c doesn't use the pm_ptr() macro to conditionallydiscard resume/suspend assignments, which causes undefined symbolerrors at link time when !PM.We could fix that by using pm_ptr(), but supporting the !PM case makeslittle sense (the whole point of these embedded GPUs is to be low power,so proper PM is a basic requirement in that case). So let's just enforcethe presence of CONFIG_PM with a Kconfig dependency instead.If someone needs to relax this dependency, it can be done in a follow-up.Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202403031944.EOimQ8WK-lkp@intel.com/Signed-off-by: Boris Brezillon Reviewed-by: Liviu Dudau Reviewed-by: Steven Price Link: https://patchwork.freedesktop.org/patch/msgid/20240304090812.3941084-4-boris.brezillon@collabora.com List of files: /linux-6.15/drivers/gpu/drm/panthor/Kconfig

d72f0490 - drm/panthor: Allow driver compilation

Thu, 29 Feb 2024 16:22:26 +0000

drm/panthor: Allow driver compilationNow that all blocks are available, we can add/update Kconfig/Makefilefiles to allow compilation.v6:- Add Maxime's and Heiko's acks- Keep source files alphabetically ordered in the Makefilev4:- Add Steve's R-bv3:- Add a dep on DRM_GPUVM- Fix dependencies in Kconfig- Expand help text to (hopefully) describe which GPUs are to be supported by this driver and which are for panfrost.Co-developed-by: Steven Price Signed-off-by: Steven Price Signed-off-by: Boris Brezillon Acked-by: Steven Price # MIT+GPL2 relicensing,ArmAcked-by: Grant Likely # MIT+GPL2 relicensing,LinaroAcked-by: Boris Brezillon # MIT+GPL2 relicensing,CollaboraReviewed-by: Steven Price Acked-by: Maxime Ripard Acked-by: Heiko Stuebner Link: https://patchwork.freedesktop.org/patch/msgid/20240229162230.2634044-13-boris.brezillon@collabora.com List of files: /linux-6.15/drivers/gpu/drm/panthor/Kconfig
