drm: pl111: Absorb the external register header

2020-06-29T22:32:59+00:00

The PL111 DRM driver is now the sole user of the external CLCD registers header file, so let's absorb that into the pl111_drm.h file and save the external include.

drm: pl111: Credit where credit is due

2020-06-29T22:20:58+00:00

This moves over some of the credit for the development of this driver from the old fbdev driver that I used as reference when getting this in place.

drm: pl111: Move VExpress setup into versatile init

2020-04-28T19:06:20+00:00

Since the VExpress setup in pl111_vexpress.c is now just a single function call, let's move it into pl111_versatile.c and we can further simplify pl111_versatile_init() by moving the other pieces for VExpress into pl111_vexpress_clcd_init().

drm: pl111: Simplify vexpress init

2020-04-28T19:06:20+00:00

The init VExpress variants currently instantiates a 'muxfpga' driver for the sole purpose of getting a regmap for it. There's no reason to instantiate a driver and doing so just complicates things. The muxfpga driver also isn't unregistered properly on module unload. Let's just simplify all this this by just calling devm_regmap_init_vexpress_config() directly.

drm/pl111: Drop explicit drm_mode_config_cleanup call

2020-03-26T15:05:39+00:00

It's right above the drm_dev_put(). This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). Aside: This driver gets its devm_ stuff all wrong wrt drm_device and anything hanging off that. Not the only one unfortunately. v2: Explain why this cleanup is possible (Laurent). v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas) Acked-by: Sam Ravnborg Cc: Sam Ravnborg Cc: Thomas Zimmermann Cc: Laurent Pinchart Signed-off-by: Daniel Vetter Cc: Eric Anholt Link: https://patchwork.freedesktop.org/patch/msgid/20200323144950.3018436-36-daniel.vetter@ffwll.ch

drm: convert .debugfs_init() hook to return void.

2020-03-18T16:53:28+00:00

As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

drm/pl111: make pl111_debugfs_init return 0

2020-03-18T15:27:06+00:00

Since 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) drm_debugfs_create_files() should return void. Therefore, remove its use as the return value in pl111_debugfs_init(), and have the function return 0 directly. v2: have pl111_debugfs_init() return 0 instead of void to avoid build breakage for individual compilation.

drm/pl111: Support Integrator IM-PD1 module

2020-02-16T13:31:30+00:00

The last in-kernel user of the old framebuffer driver is the IM-PD1 module for the Integrator/AP. Let's implement support for this remaining user so we can migrate the last user over to DRM and delete the old FB driver. On the Integrator/AP the IM-PD1 system controller will exist alongside the common Integrator system controller so make sure to do a special lookup for the IM-PD1 syscon and make it take precedence if found. Tested on the Integrator/AP with the IM-PD1 mounted.

drm: get drm_bridge_panel connector via helper

2019-12-09T21:57:26+00:00

The drm_connector created by drm_panel_bridge was accessed via drm_panel.connector. Avoid the detour around drm_panel by providing a simple get method. This avoids direct access to the connector field in drm_panel in the two users. The change is done in preparation for removal of drm_panel.connector. Update pl111 and tve200 to use the new helper.
