drm/mcde: fix masking and bitwise-or on variable val

2020-11-25T20:58:35+00:00

The masking of val with ~MCDE_CRX1_CLKSEL_MASK is currently being ignored because there seems to be a missing bitwise-or of val in the following statement. Fix this by replacing the assignment of val with a bitwise-or.

drm/mcde: Support DPI output

2020-11-23T23:09:08+00:00

This implements support for DPI output using the port node in the device tree to connect a DPI LCD display to the MCDE. The block also supports TV-out but we leave that for another day when we have a hardware using it. We implement parsing and handling of the "port" node, and follow that to the DPI endpoint. The clock divider used by the MCDE to divide down the "lcdclk" (this has been designed for TV-like frequencies) is represented by an ordinary clock provider internally in the MCDE. This idea was inspired by the PL111 solution by Eric Anholt: the divider also works very similar to the Pl111 clock divider. We take care to clear up some errors regarding the number of available formatters and their type. We have 6 DSI formatters and 2 DPI formatters. Tested on the Samsung GT-I9070 Janice mobile phone.

drm/mcde: Break out DSI set-up routine

To be able to support DPI without messing things up we first break out the DSI set-up to a separate function.

drm/mcde: Fix RGB/BGR bug

2020-11-23T23:07:04+00:00

I was confused when the graphics came out with blue penguins on the DPI panel. It turns out that the so-called "packed RGB666" mode on the DSI formatter is incorrect: this mode is the actual RGB888 mode, and the mode called RGB888 is BGR888. The claims that the MCDE had inverse RGB/BGR buffer formats was wrong, so correct this and the buggy register and everything is much more consistent, and graphics look good on all targets, both DPI and DSI.

drm/mcde: Fix unbalanced regulator

2020-11-10T23:27:53+00:00

Since we now turn off the EPOD regulator to reset the hardware, we need to balance the regulators after that point. If registering the master fails we only need to disable one regulator. Fix this by open-coding this leg of the error path.

drm/: Constify struct drm_driver

2020-11-06T09:31:26+00:00

Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg Cc: kernel test robot Acked-by: Maxime Ripard Reviewed-by: Alex Deucher Signed-off-by: Daniel Vetter Cc: Sam Ravnborg Cc: Dave Airlie Cc: Gerd Hoffmann Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland Cc: Leo Li Cc: Alex Deucher Cc: Christian König Cc: Eric Anholt Cc: Maxime Ripard Cc: Ben Skeggs Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch
