From 89b2b6186d259014c217d887463a5030d0c5f23a Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Wed, 31 May 2017 17:59:29 +0200 Subject: [PATCH] rockchip: video: Kconfig: set MAX_XRES and MAX_YRES via Kconfig This introduces two new Kconfig options that configure the maximum allowable framebuffer size (i.e. the memory reservation/allocation for the framebuffer): - VIDEO_ROCKCHIP_MAX_XRES - VIDEO_ROCKCHIP_MAX_YRES The resulting memory allocation will cover 4 byte per pixel for these resolutions.
