From d837736a0515c305aa902c9f8702065064827891 Mon Sep 17 00:00:00 2001 From: Ruihai Zhou Date: Tue, 26 Mar 2024 14:49:07 +0800 Subject: [PATCH] drivers/mipi: Fine tune clock for IVO_T109NW41 Fine tune the panel clock to prevent mipi noise from affecting wifi band. After tuning, the panel refresh rate keeps at 60Hz and wifi test passed. Just keep consistent with the Linux kernel panel driver panel-boe-tv101wum-nl6 configuration.
