* ISSI31FL3733 driver - Addapted IS31 driver for the above driver * fix my branch * ISSI31FL3733 driver - Inclusion of above ISSI led driver * IS31fl3733 driver - Added correct function for control registers * Finalized support for ISSI31fl3733 led driver - Finalized and tested driver. - Modified i2c_master for arm due to declaration mistake. - Fixed spaces/tabs in quantum.h file. - Fixed spaces/tabs in common_features.mk file. - Removed unnecessary includes from rgb_matrix.c file. - Added local definitions for MIN and MAX macros in rgb_matrix.c file. - Adjusted chevron effect. - Added necessary define (RGB_3733_MATRIX_ENABLE) for makefile. - Added necessary C define (ISSI3733) to aid with inclusion of the correct header file. - Added documentation for the new driver. * Driver structure update - Changed rule includes to be more condensed (RGB_MATRIX_ENABLE = IS31FL3731) and (RGB_MATRIX_ENABLE = IS31FL3733) - Updated documentation - Reverted to the use of differently named functions for each driver and selecting the needed ones within rgb_matrix.c * ISSI Drivers refractoring - Moved issi drivers in a dedicated folder - Updated documentation * I2C library fix I released the special pins incorrectly before. It is now fixed.
