How do we want to handle mixed case identifiers such as LTDC_LxBFCR_BF1, LTDC_LxBFCR_BF2, LTDC_LxCFBLR_CFBLL, LTDC_LxCFBLR_CFBP, LTDC_LxCR_CLUTEN, LTDC_LxCR_COLKEN, LTDC_LxCR_LEN, LTDC_LxWVPCR_WVSPPOS, LTDC_LxWVPCR_WVSTPOS, STM32_LTDC_LxWHPCR_WHSTPOS, STM32_LTDC_LxWVPCR_WVSTPOS, and STM32_LTDC_Lx_BYPP? These examples are found in arch/arm/src/stm32/stm32_ltdc.c and nxstyle complains about them because of the lowercase 'x'. There are other examples within arch/stm32 that I'd like to fix as well.
Thanks, Nathan
