Remove firmware devices on the PCI bus, by calling aperture_remove_conflicting_pci_devices() in the probe function of each related fbdev driver. iSo far, most of these drivers did not remove conflicting VESA or EFI devices, or outride failed for resource conflicts (i.e., matroxfb.) This must have been broken for quite some time. Signed-off-by:

Convert fbdev drivers from fbdev's remove_conflicting_framebuffers() to the framework-independent aperture_remove_conflicting_devices(). Calling this function will also remove conflicting DRM drivers. Signed-off-by:

Remove remove_conflicting_pci_framebuffers() and implement similar functionality in aperture_remove_conflicting_pci_device(), which was the only caller. Removes an otherwise unused interface and streamlines the aperture helper. No functional changes. Signed-off-by:

Move vgag16fb's option parsing into the driver's probe function and generate the rest of the module's init/exit functions from macros. Keep the options code, although there are no options defined. v2: * no options are supported, remove the code (Javier) Signed-off-by:

Move the device-creation from vga16fb to sysfb code. The driver's videomode checks are independent from device creation, so move them into vga16fb's probe function. This will allow to create the module init/exit code automatically. The vga16fb driver requires a screen_info for type VIDEO_TYPE_VGAC or VIDEO_TYPE_EGAC. Such code is nowhere present in the kernel, except for some MIPS systems. It's not clear if the vga16fb driver actually works in practice. v2: * keep driver name to "vga16fb" (Javier) * give rational for moving mode checks (Javier) Signed-off-by:

The ST7701 initialization sequence is well parametrized, split the GIP programming sequence, which is fully custom completely undocumented TFT matrix specific magic register programming sequence into separate callback so other TFT matrix definitions can add their own GIP sequence. Signed-off-by:

The horizontal pixel count is a property of the TFT matrix. Currently the driver hard-codes content of this register to specific value which is only compatible with one TFT matrix, likely the TS8550B one. Calculate the horizontal pixel count from the mode instead. Signed-off-by:

Define DSI_CMD2_BK0_PORCTRL_VBP_MASK and DSI_CMD2_BK0_PORCTRL_VFP_MASK and move the vertical back and front porch calculation from macros into the st7701_init_sequence() function, so it is clear what this does. No functional change. Signed-off-by:

The gamma correction values are specific to the TFT which is attached to the ST7701 TFT matrix driver, move the gamma correction values from what incorrectly looks like common init sequence into TFT matrix specific settings. While doing so, add macros which defined fields within the gamma register file and a macro which mimics FIELD_PREP except works with constant expressions. Signed-off-by:

The ST7701 and ST7701S all have two voltage supplies, one for internal logic and one for the TFT matrix driver. The supplies are not property of the TFT matrix driver, so move them to common ST7701 code. Signed-off-by:

The ST7701(S) is capable of DSI burst mode, which is more energy efficient than the non-burst modes. Make use of it. The ST7701(S) is capable of DSI non-continuous clock, since it sources the TFT matrix driver clock from internal clock source. The DSI non-continuous clock further reduce power utilization. The ST7701(S) uses DSI LPM for command transmissions, make sure this is configured correctly in the DSI mode flags. Signed-off-by:

Marek Vasut authored
The ST7701 and ST7701S are TFT matrix drivers with integrated multi protocol decoder capable of DSI/DPI/SPI input and 480x360...864 line TFT matrix output. Currently the only supported input is DSI. The protocol decoder is separate from the TFT matrix driver and is always capable of handling all of DSI non-burst mode with sync pulses or sync events as well as DSI burst mode. Move the DSI mode configuration from TFT matrix driver properties to common ST7701 code, because this is common to all TFT matrices. Signed-off-by:

Data writes for the ssd130x 4-wire SPI protocol need special handling, due the Data/Command control (D/C) pin having to be toggled prior to the write. The regmap API only allowed drivers to provide .reg_{read,write} callbacks to do per register read/write, but didn't provide a way for drivers to do the same for bulk read/writes. For this reason, a custom regmap bus was used by the driver just to define a bulk write callback that implements the D/C pin toggling. But the regmap API has been extended to support defining bulk read/write handlers, so the custom regmap bus is not needed anymore and could just be dropped.

Add FourCCs for two missing permutations of the packed YUV 4:4:4 color components, namely AVUY and XVUY. These formats are needed by the NXP i.MX8 ISI. While the ISI is supported by a V4L2 device (corresponding formats have been submitted to V4L2), it is handled in userspace by libcamera, which uses DRM FourCCs for pixel formats. Signed-off-by:

The macros for texture 1 setting all used continuation on a new line, resulting in a highly ureadable definition. Merge the lines so they are each on a single line. As a nice side-effect this fixes a number of checkpatch warnings: "WARNING: please, no spaces at the start of a line". Suggested-by:

The via driver implements the DRI1 interface, and we have a new implementation of the via driver coming that supports atomic modesetting. It is not acceptable just to replace the existing driver so this is first step to make it a single-file implementation allowing it to stay without interfering with the new driver. Signed-off-by:
