From d653bd394823772f0696c0642be94d78d5562e41 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 10 Apr 2019 08:38:14 +0200 Subject: drm: switch drm_fb_xrgb8888_to_rgb565_dstclip to accept __iomem dst MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Not all archs have the __io_virt() macro, so cirrus can't simply convert pointers that way. The drm format helpers have to use memcpy_toio() instead. This patch makes drm_fb_xrgb8888_to_rgb565_dstclip() accept a __iomem dst pointer and use memcpy_toio() instead of memcpy(). The helper function (drm_fb_xrgb8888_to_rgb565_line) has been changed to process a single scanline.
