fbdev/xilinxfb: Use fbdev I/O helpers

2023-08-04T13:54:38+00:00

Set struct fb_ops and with FB_DEFAULT_IOMEM_OPS, fbdev's initializer for I/O memory. Sets the callbacks to the cfb_ and fb_io_ functions. Select the correct modules with Kconfig's FB_IOMEM_HELPERS token. The macro and token set the currently selected values, so there is no functional change. v3: * use _IOMEM_ in commit message v2: * updated to use _IOMEM_ tokens Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Acked-by: Helge Deller Cc: Michal Simek Link: https://patchwork.freedesktop.org/patch/msgid/20230803184034.6456-47-tzimmermann@suse.de

fbdev: Remove FBINFO_DEFAULT from devm_kzalloc()'ed structs

2023-07-24T14:50:38+00:00

The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags has been allocated to zero by devm_kzalloc(). So do not set it. Flags should signal differences from the default values. After cleaning up all occurrences of FBINFO_DEFAULT, the token will be removed. v4: * clarify commit message (Geert, Dan) v2: * fix commit message (Miguel) Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Cc: Helge Deller Link: https://patchwork.freedesktop.org/patch/msgid/20230715185343.7193-5-tzimmermann@suse.de

fbdev: Explicitly include correct DT includes

2023-07-20T05:56:30+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

fbdev: xilinxfb: Convert to platform remove callback returning void

2023-04-24T09:48:33+00:00

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 this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller

fbdev: xilinxfb: Use devm_platform_get_and_ioremap_resource()

2023-03-14T17:49:40+00:00

According to commit 890cc39a8799 ("drivers: provide devm_platform_get_and_ioremap_resource()"), convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does.

fbdev: Use of_property_read_bool() for boolean properties

2023-03-14T17:49:39+00:00

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. Convert reading boolean properties to to of_property_read_bool(). Signed-off-by: Rob Herring Signed-off-by: Helge Deller

fbdev: xilinxfb: Make xilinxfb_release() return void

2022-10-20T06:36:41+00:00

The function xilinxfb_release() returns zero unconditionally. Make it return void. There is no semantic change, the only effect is that it becomes obvious that the driver's .remove() callback always returns zero. This is a preparation for making platform remove callbacks return void. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller
