The driver only supports OLED controllers that have a native DRM_FORMAT_C1 pixel format and that is why it has harcoded a division of the width by 8. But the driver might be extended to support devices that have a different pixel format. So it's better to use the struct drm_format_info helpers to compute the size of the buffer, used to store the pixels in native format. Signed-off-by:

The resolutions for these panels are fixed and defined in the Device Tree, so there's no point to allocate the buffers on each plane update and that can just be done once. Let's do the allocation and free on the encoder enable and disable helpers since that's where others initialization and teardown operations are done. Signed-off-by:

The driver only supports OLED controllers that have a page height of 8 but there are devices that have different page heights. So it is better to not hardcode this value and instead have it as a per controller data value. Signed-off-by:

A default resolution in the ssd130x driver isn't set to an arbitrary 96x16 anymore. Instead is set to a width and height that's controller dependent. The datasheets for the chips describes the following display resolutions: - SH1106: 132 x 64 Dot Matrix OLED/PLED - SSD1305: 132 x 64 Dot Matrix OLED/PLED - SSD1306: 128 x 64 Dot Matrix OLED/PLED - SSD1307: 128 x 39 Dot Matrix OLED/PLED - SSD1309: 128 x 64 Dot Matrix OLED/PLED Update DT schema to reflect what the driver does and make its users aware.

Currently the driver hardcodes the default values to 96x16 pixels but this default resolution depends on the controller. The datasheets for the chips describes the following display controller resolutions: - SH1106: 132 x 64 Dot Matrix OLED/PLED - SSD1305: 132 x 64 Dot Matrix OLED/PLED - SSD1306: 128 x 64 Dot Matrix OLED/PLED - SSD1307: 128 x 39 Dot Matrix OLED/PLED - SSD1309: 128 x 64 Dot Matrix OLED/PLED Add this information to the devices' info structures, and use it set as a default if not defined in DT rather than hardcoding to an arbitrary value.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert the omap drm driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

Simplify and unify naming convention in MMU600 page tables configuration. All DMA addresses in page tables directly accessed by VPU are called with _dma sufix and all CPU pointers to those page tables have _ptr sufix. Base pointers used to do a page walk on the CPU have corresponding names: pud_ptrs (pointers used to get access to PUD DMA) pmd_ptrs (pointers used to get access to PMD DMA) pte_ptrs (pointers used to get access to PTE DMA) with the following convention: u64 *pud_dma_ptr = pud_ptrs[pgd_idx]; *pud_dma_ptr = pud_dma; u64 *pmd_dma_ptr = pmd_ptrs[pgd_idx][pud_idx]; *pmd_dma_ptr = pmd_dma; u64 *pte_dma_ptr = pte_ptrs[pgd_idx][pud_idx][pmd_idx]; *pte_dma_ptr = pte_dma; On the way change to coherent dma allocation, _wc is only valid on ARM and was used by mistake.
