Hello, this series is rebased onto Ben Dook's framebuffer branch available at: git://git.fluff.org/bjdooks/linux.git dev/s3c-fb The main changes are the addition of an ability to wait for VSYNC and display panning and a better support for S5PV210 SoCs. A number of bugs has also been fixed. The first patch attempts to fix some NULL pointer dereferences in case of a failed framebuffer memory allocation attempt. This is a quick fix, so please treat it more as an indication of what may be wrong with the code in the probe function and not as something to merge. Patches 3-4 add "new style" device name initialization for various S3C/S5P devices. The 4th patch also separates S5PC100 and S5PV210 as their framebuffer registers sets differ. Patches 8, 10 add shadow register update locking (S3C6410+) Patch 12 Adds support for DMA channel control found on S5PV210+ Patches 7, 9 and 11 are pure bugfixes. Changes in v3: - new patches: * fixing a section mismatch error * adding support for DMA channel control (enable/disable) found on S5PV210 * disabling shadow register updates during set_par - unified function for disabling register updates - no need to initialize names for 64xx-type framebuffers (is being set as default anyway) - updated to the new version of Ben's branch - minor fixes Changes in v2: - added SHADOWCON register support found on S3C6410 and S5PC100 for disabling shadow register updates - fixed osd and alpha register handling (different configurations for different machines) The series includes: [PATCH v3 01/12] s3c-fb: Fix various null references on framebuffer memory alloc failure [PATCH v3 02/12] s3c-fb: Correct FRAMESEL1 bitfield defines for VIDINTCON0 register [PATCH v3 03/12] s3c-fb: Separate S5PC100 and S5PV210 framebuffer driver data structures [PATCH v3 04/12] s3c-fb: Add device name initialization [PATCH v3 05/12] s3c-fb: Add support for display panning [PATCH v3 06/12] s3c-fb: Add wait for VSYNC ioctl [PATCH v3 07/12] s3c-fb: window 3 of 64xx+ does not have an osd_d register [PATCH v3 08/12] s3c-fb: Add SHADOWCON shadow register locking support for S5PV210 [PATCH v3 09/12] s3c-fb: Correct window osd size and alpha register handling [PATCH v3 10/12] s3c-fb: Protect window-specific registers during updates [PATCH v3 11/12] s3c-fb: fix section mismatch [PATCH v3 12/12] s3c-fb: Add support for DMA channel control on S5PV210 Best regards -- Pawel Osciak Linux Platform Group Samsung Poland R&D Center
