From: Bartosz Golaszewski <redacted> Since commit eb3744a2dd01 ("gpio: davinci: Do not assume continuous IRQ numbering") the davinci GPIO driver fails to probe if we boot in legacy mode from any of the board files. Since the driver now expects every interrupt to be defined as a separate resource, split the definition in devices-da8xx.c instead of having a single continuous interrupt range. Fixes: eb3744a2dd01 ("gpio: davinci: Do not assume continuous IRQ numbering") Cc: stable at vger.kernel.org Signed-off-by: Bartosz Golaszewski <redacted>There are a number of other boards that need such fixing too. And the commit in question does not do a good job of explaining why it was needed in the first place. The description just repeats what can be inferred by reading the patch.Cc Lokesh Sekhar, DT explicitly mentions every IRQ number. The patch in discussion explicitly calls platform_get_irq for all the interrupts which to me is the right thing to do as: platform_get_irq--> of_irq_get-->irq_create_of_mapping--> sequence is to be done for every IRQ. k3-am654 definitely will need explicit calls to platform_get_irq as it will be involving interrupt router and interrupt numbers need not be continuous. So i do not think reverting the patch is the right idea.Well, all of this description of patch motivation should have been in the patch description to begin with. Bartosz, can you please extend this patch to fix this problem for other DaVinci SoCs too? I am on the road this week, but will do my best to queue these fixes at the earliest . Thanks, Sekhar
Ok, to make it easier for you, I'll resend all the patches addressing the GPIO issue. Bart
