Update simplefb to support the new preferred location for simplefb dt nodes under /chosen.
Signed-off-by: Hans de Goede <[email protected]> -- Changes in v2: -Make name array larger in case we ever encounter more then 10000 framebuffers Changes in v3: -Switch to for_each_child_of_node to loop over the nodes under chosen Changes in v4: -Wrap the chosen enumeration code in #ifdef CONFIG_OF, as simplefb is used on non devicetree platforms too -simplefb can only be built-in, so drop the module_exit function calling platform_driver_unregister --- drivers/video/fbdev/simplefb.c | 23 ++++++++++++++++++++++- 1 file changed, 22 insertions(+), 1 deletion(-) diff --git a/drivers/video/fbdev/simplefb.c b/drivers/video/fbdev/simplefb.c index 868099a..e381a53 100644 --- a/drivers/video/fbdev/simplefb.c +++ b/drivers/video/fbdev/simplefb.c @@ -27,6 +27,7 @@ #include <linux/platform_data/simplefb.h> #include <linux/platform_device.h> #include <linux/clk-provider.h> +#include <linux/of_platform.h> static struct fb_fix_screeninfo simplefb_fix = { .id = "simple", @@ -390,7 +391,27 @@ static struct platform_driver simplefb_driver = { .probe = simplefb_probe, .remove = simplefb_remove, }; -module_platform_driver(simplefb_driver); + +static int __init simplefb_init(void) +{ + int ret; + struct device_node __maybe_unused *np; + + ret = platform_driver_register(&simplefb_driver); + if (ret) + return ret; + +#ifdef CONFIG_OF + for_each_child_of_node(of_chosen, np) { + if (of_device_is_compatible(np, "simple-framebuffer")) + of_platform_device_create(np, NULL, NULL); + } +#endif + + return 0; +} + +module_init(simplefb_init); MODULE_AUTHOR("Stephen Warren <[email protected]>"); MODULE_DESCRIPTION("Simple framebuffer driver"); -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
