[PATCH v2 1/3] drm/msm: drop register logging support

[PATCH v2 1/3] drm/msm: drop register logging support

[Dmitry Baryshkov]

Register logging was used during early stages of msm driver development
to compare upstream and downstream register traces. However the tool was
never updated to work with mdp5 hardware. Later it was dropped
completely when Rob imported freedreno tools into mesa. All this makes
DRM_MSM_REGISTER_LOGGING irrelevant now, so it can be dropped.

msm_ioremap() functions take additional argument dbgname which is now
unused.

[PATCH v2 3/3] drm/msm: move msm_readl/_writel to msm_drv.h

[Dmitry Baryshkov]

With the reglog removal, msm_readl/_writel became single line wrappers
around readl/writel. Move those two wrappers and msm_rmw to msm_drv.h to
remove need for extra function calls when doing register writes.

Any chance this can go further and replace msm_readl/msm_writel with
readl/writel directly?

This can go on a step-by-step basis. But practically yes. With this
change in place we should be able to drop most of the io wrappers.
