drm/ast: Move code for physical outputs into separate files

2024-08-22T07:12:46+00:00

Move the modesetting code for the various transmitter chips into their own source files before adding BMC support. No functional changes. Signed-off-by: Thomas Zimmermann Reviewed-by: Jocelyn Falempe Link: https://patchwork.freedesktop.org/patch/msgid/20240815151953.184679-2-tzimmermann@suse.de

drm/ast: Move DDC code to ast_ddc.{c,h}

2024-04-02T08:40:46+00:00

Rename ast_i2c.c to ast_ddc.c and move its interface into the new header ast_ddc.h. Update all include statements as necessary and change the adapter name to 'AST DDC bus'. This avoids including I2C headers in the driver's main header file, which doesn't need them. Renaming files to _ddc indicates that the code is about the DDC. I2C is really just the underlying bus here.

drm/ast: Create the driver for ASPEED proprietory Display-Port

2022-05-03T14:04:03+00:00

V1: 1. The MCU FW controling ASPEED DP is loaded by BMC boot loader. 2. Driver starts after CR[3:1] == 111b that indicates Tx is ASTDP, and CRD1[5] has been asserted by BMVC boot loader. 3. EDID is prioritized by DP monitor. 4. DP's EDID has high priority to decide resolution supporting. V2: Modules description: 1. ASTDP (ASPEED DisplayPort) is controlled by dedicated AST-MCU (ASPEED propriatary MCU). 2. MCU is looping in charged of HPD, Read EDID, Link Training with DP sink. 3. ASTDP and AST-MUC reside in BMC (Baseboard Management controller) addressing-space. 4. ASPEED DRM driver requests MCU to get HPD and EDID by CR-scratched register. Booting sequence: 1. Check if TX is ASTDP // ast_dp_launch() 2. Check if DP-MCU FW has loaded // ast_dp_launch() 3. Read EDID // ast_dp_read_edid() 4. Resolution switch // ast_dp_SetOutput() V3: 1. Remove unneeded semicolon. 2. Apply to git://anongit.freedesktop.org/drm/drm, instead of git://anongit.freedesktop.org/drm/drm-misc 3. Resolve auto build test WARNINGs on V1 patch. V4: 1. Sync code-base with kernel 5.17_rc6 2. Remove the define of DPControlPower, because DP chips need to be powered on to be used. 3. Remove the switches of PHY and Display from EDID procedure. 4. Revise increaing delay to fixed delay, because this version kernel doesn't detect minitor consistenntly. 5. Create clean-up code used for reset of power state on errors with -EIO manner. 6. Revise the DP detection by TX type and its DP-FW status during booting and resume. 7. Correct the CamelCase Style. 8. Use register reading while needing, and remove to hold full register. 9. Instead of 'u8', revise to 'bool' on swwitch of PHY and video. 10.Correct typo 11.Remove the duplicated copy of TX definition. 12.Use EDID_LENGTH as the constant of 128.

drm/ast: Inline ast cursor-update functions into modesetting code

2021-02-17T11:40:05+00:00

The logic for cursor updates is now located in the cursor plane's modesetting code. A number of helper functions remain to modify the rsp registers and image.

drm/ast: Replace struct ast_fbdev with generic framebuffer emulation

2019-07-09T08:25:12+00:00

This patch replaces ast's framebuffer console with DRM's generic implememtation. All respective code is being removed from the driver. The console is set up with a shadow buffer. The actual buffer object is not permanently pinned in video ram, but just another buffer object that the driver moves in and out of vram as necessary. The driver's function ast_crtc_do_set_base() used to contain special handling for the framebuffer console. With the new generic framebuffer, the driver does not need this code an longer. v2: * use drm_fb_helper_set_suspend_unlocked() in ast_drm_{thaw,freeze}() * dirty function no longer required Signed-off-by: Thomas Zimmermann Acked-by: Noralf Trønnes Link: https://patchwork.freedesktop.org/patch/315835/
