Kernel for Galaxy S24, rebased on CLO sources (WIP)
4919043ab9
commit 6bc3462a0f5ecaa376a0b3d76dafc55796799e17 upstream. Shubhra reports that their laptop is heating up over s2idle. Even though it's getting into the deepest state, it appears to be having spurious wakeup events. While debugging a tangential issue with the RTC Carsten reports that recent 6.1.y based kernel face a similar problem. Looking at acpidump and GPIO register comparisons these spurious wakeup events are from the GPIO associated with the I2C touchpad on both laptops and occur even when the touchpad is not marked as a wake source by the kernel. This means that the boot firmware has programmed these bits and because Linux didn't touch them lead to spurious wakeup events from that GPIO. To fix this issue, restore most of the code that previously would clear all the bits associated with wakeup sources. This will allow the kernel to only program the wake up sources that are necessary. This is similar to what was done previously; but only the wake bits are cleared by default instead of interrupts and wake bits. If any other problems are reported then it may make sense to clear interrupts again too.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
