video: constify fb ops across all drivers

2019-12-05T08:57:53+00:00

Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com

fbdev: da8xx: use resource management for dma

2019-08-26T12:24:00+00:00

Use managed variants of dma alloc functions in the da8xx fbdev driver. Signed-off-by: Bartosz Golaszewski Acked-by: Bartlomiej Zolnierkiewicz Signed-off-by: Sekhar Nori

fbdev: da8xx-fb: drop a redundant if

2019-08-26T12:23:59+00:00

The driver data is always set in probe. The remove() callback won't be called if probe failed which is the only way for it to be NULL. Remove the redundant if. Signed-off-by: Bartosz Golaszewski Acked-by: Bartlomiej Zolnierkiewicz Signed-off-by: Sekhar Nori

fbdev: da8xx-fb: use devm_platform_ioremap_resource()

2019-08-26T12:23:59+00:00

Shrink the code a bit by using the new helper wrapping the calls to platform_get_resource() and devm_ioremap_resource() together. Signed-off-by: Bartosz Golaszewski Acked-by: Bartlomiej Zolnierkiewicz Signed-off-by: Sekhar Nori

fbdev: da8xx: remove panel_power_ctrl() callback from platform data

2019-08-26T12:23:58+00:00

There are no more users of panel_power_ctrl(). Remove it from the driver. Signed-off-by: Bartosz Golaszewski Acked-by: Bartlomiej Zolnierkiewicz Signed-off-by: Sekhar Nori

fbdev: da8xx: add support for a regulator

2019-08-26T12:23:57+00:00

We want to remove the hacky platform data callback for power control. Add a regulator to the driver data and enable/disable it next to the current panel_power_ctrl() calls. We will use it in subsequent patch on da850-evm. Signed-off-by: Bartosz Golaszewski Acked-by: Bartlomiej Zolnierkiewicz Signed-off-by: Sekhar Nori

video: fbdev: don't print error message on framebuffer_alloc() failure

2019-06-28T10:30:08+00:00

framebuffer_alloc() can fail only on kzalloc() memory allocation failure and since kzalloc() will print error message in such case we can omit printing extra error message in drivers (which BTW is what the majority of framebuffer_alloc() users is doing already).

da8xx-fb: pass struct device to DMA API functions

2019-04-08T15:52:24+00:00

The DMA API generally relies on a struct device to work properly, and only barely works without one for legacy reasons. Pass the easily available struct device from the platform_device to remedy this. Signed-off-by: Christoph Hellwig Acked-by: Bartlomiej Zolnierkiewicz

cross-tree: phase out dma_zalloc_coherent()

2019-01-08T12:58:37+00:00

We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out.
