- OTG support - Charger - WiFi 5GHz - RTC bug "fixed" (always-on interrupt - made device overheat!) - Kernel version bumped to 5.2.1 - Memory timings - New WM8994 codec board driver (fixes suspend/resume) - Camera's regulator supported now (saves power at least!) - Updated panel driver (still not in mainline, idk why) - MHL support in kernel (fixes boot times and screen, currently disabled in X, not tested) - Other minor kernel chagnes [ci:skip-build]: already built successfully in CI

Subject: [PATCH] ARM: dts: tegra20-glide: Fix audio power binding
|
|
|
|
The LDO definition in wm8994 node is used for internal LDOs, but not for
|
|
powering the chip, so we use the fixed regulator to resolve this.
|
|
All regulators of wm8994 are defined to suppress messages in dmesg.
