linux-samsung-a5y17lte : fix linter issues Add descriptions to patches Prefix custom variable with '_' Refactoring change, [ci:skip-vercheck]
2020-09-15 18:55:02 +00:00
This patch allows to configure kernel with MUIC debug possibility.
Allows to dump MUIC registers via sysfs and more.
To configure kernel with muic debug enabled, set SAMSUNG_MUIC, and DEBUG_MUIC options
samsung-a5y17lte: kconfig: add muic debug option (!556) Some Samsung muic's have debug possibility, but seems kernel config option for that was deleted. Muic debug can be useful for attaching UART cable to phone. [ci:skip-build]: already built successfully in CI
