Series add support MDP3 on MT8195 platform | expand

Moudy Ho Sept. 12, 2023, 7:57 a.m. UTC
MT8195 has two MMSYS sets, VPPSYS0 and VPPSYS1.
These sets coordinate and control the clock, power, and
register settings needed for the components of MDP3.

Fixing the error handling shall be done in a different commit, which shall also
have a Fixes tag: this is both for backporting purposes and because those fixes
are not relevant to adding support for secondary sets of MMSYS (so, those are
not relevant for this specific commit).

I'm wondering if this would become more readable by doing it like so:

	struct mdp_dev_infra {
		struct device *mmsys;
		struct mtk_mutex *mtk_mutex[MDP_PIPE_MAX];
	}

	struct mdp_dev {
		struct platform_device *pdev;
		struct mdp_dev_infra mdp_infra;
		.....
	}

so that you can add the secondary MMSYS (that goes along with the secondary
MUTEX anyway) by then changing mdp_infra to

		struct mtk_dev_infra mdp_infra[NUM_MMSYS];

and then referencing that like

mdp->mdp_infra[MDP_INFRA_MMSYS0]->mmsys
mdp->mdp_infra[MDP_INFRA_MMSYS0]->mtk_mutex
mdp->mdp_infra[MDP_INFRA_MMSYS1]->mmsys
mdp->mdp_infra[MDP_INFRA_MMSYS1]->mtk_mutex

What do you think?

Regards,
Angelo

Thanks forreminding me. I will address this error handing separately in
a dedicated fix patch.
