Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

Three low-level functions in hdmi4.c and hdmi4_core.c are made available for use by the OMAP4 CEC support. Renamed the prefix to hdmi4 since these are OMAP4 specific. These function deal with the HDMI core and are needed to power it up for use with CEC, even when the HPD is low. Background: even if the HPD is low it should still be possible to use CEC. Some displays will set the HPD low when they go into standby or when they switch to another input, but CEC is still available and able to wake up/change input for such a display. This is explicitly allowed by the CEC standard. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
