Add support for PMIC MIPI sequences using the new intel_soc_pmic_exec_mipi_pmic_seq_element function. This fixes the DSI LCD panel not lighting up when not initialized by the GOP (because an external monitor was connected) on GPD win and GPD pocket devices. Specifically the LCD panel seems to need GPIO pin 9 on the PMIC to be driven high, which is done through a PMIC MIPI sequence. Before this commit if the sequence was not executed by the GOP the pin would stay low causing the LCD panel to not work. Having the MIPI sequences properly control this GPIO should also help save some power when the panel is off. Changes in v2, v3: -Only changes to other patches in this patch-set Changes in v4: -Move decoding of the raw 15 bytes PMIC MIPI sequence element into i2c-address, register-address, value and mask into the mipi_exec_pmic() function instead of passing the raw data to intel_soc_pmic_exec_mipi_pmic_seq_element() Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190107111556.4510-5-hdegoede@redhat.com |

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.
