Subject: mfd: Add tps65910 32-kHz-crystal-input init
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d02e83cbcc4fe2b821a7ecd6464a14d6ad045187;p=linux-beck.git

mfd: Add tps65910 32-kHz-crystal-input init

Replace tps65910_misc_init with a dedicated init function for the
32-kHz-crystal input, and make the code more readable.
