TI LMU (Lighting Management Unit) driver supports lighting devices below. LM3532, LM3631, LM3632, LM3633, LM3695 and LM3697. LMU devices have common features. - I2C interface for accessing device registers - Hardware enable pin control - Backlight brightness control - Notifier for hardware fault monitoring - Regulators for LCD display bias It contains fault monitor, backlight, LED and regulator driver. LMU fault monitor ----------------- LM3633 and LM3697 provide hardware monitoring feature. It enables open or short circuit detection. After monitoring is done, each device should be re-initialized. Notifier is used for this case. Separate patch for 'ti-lmu-fault-monitor' will be sent later. Backlight --------- It's handled by TI LMU backlight consolidated driver and chip dependent data. Separate patchset will be sent later. LED indicator ------------- LM3633 has 6 indicator LEDs. Programmable dimming pattern is also supported. Separate patch for 'leds-lm3633' will be sent later. Regulator --------- LM3631 has 5 regulators for the display bias. LM3632 supports 3 regulators. One consolidated driver enables it. The lm363x regulator driver is already upstreamed.

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.
