[PATCH v2 0/2] Fixes and enhancements for Exynos (7870) DSIM bridge driver
Posted by Kaustabh Chakraborty 10 hours ago
Since v6.17, there is a regression for the Exynos 7870 DSIM driver. The
display occasionally had random aberration when the panel was turned on.
The first patch addresses that.

The second patch replaces an implicit loop for waiting for PLL
stabilization with an interrupt-based solution, which should be more
reliable. This solution was suggested by Inki Dae in a discussion of an
earlier patch series sent by me. For further details, refer to its
commit description.
