If a device is wired -to multiple interrupt controllers, then it needs to be attached to a -node with an interrupt-map property to demux the interrupt specifiers -which is confusing. It would be a lot easier if there was a form of the -interrupts property that allows for a separate interrupt phandle for -each interrupt specifier. - -This patch does exactly that by creating a new interrupts-extended -property which reuses the phandle+arguments pattern used by GPIOs and -other core bindings. - -Signed-off-by: Grant Likely <grant.likely@linaro.org> -Acked-by: Tony Lindgren <tony@atomide.com> -Acked-by: Kumar Gala <galak@codeaurora.org> -[grant.likely: removed versatile platform hunks into separate patch] -Cc: Rob Herring <rob.herring@calxeda.com> - -Conflicts: - arch/arm/boot/dts/testcases/tests-interrupts.dtsi - drivers/of/selftest.c ---- - drivers/of/selftest.c | 146 +++++++++++++++++++++++++++++++++++++++++++++++++- - 1 file changed, 145 insertions(+), 1 deletion(-) - ---- a/drivers/of/selftest.c -+++ b/drivers/of/selftest.c -@@ -154,6 +154,147 @@ static void __init of_selftest_property_ - selftest(rc == -EILSEQ, "unterminated string; rc=%i", rc); - } - -+static void __init of_selftest_parse_interrupts(void) -+{ -+ struct device_node *np; -+ struct of_phandle_args args; -+ int i, rc; -+ -+ np = of_find_node_by_path("/testcase-data/interrupts/interrupts0"); -+ if (!np) { -+ pr_err("missing testcase data\n"); -+ return; -+ } -+ -+ for (i = 0; i < 4; i++) { -+ bool passed = true; -+ args.args_count = 0; -+ rc = of_irq_parse_one(np, i, &args); -+ -+ passed &= !rc; -+ passed &= (args.args_count == 1); -+ passed &= (args.args[0] == (i + 1)); -+ -+ selftest(passed, "index %i - data error on node %s rc=%i\n", -+ i, args.np->full_name, rc); -+ } -+ of_node_put(np); -+ -+ np = of_find_node_by_path("/testcase-data/interrupts/interrupts1"); -+ if (!np) { -+ pr_err("missing testcase data\n"); -+ return; -+ } -+ -+ for (i = 0; i < 4; i++) { -+ bool passed = true; -+ args.args_count = 0; -+ rc = of_irq_parse_one(np, i, &args); -+ -+ /* Test the values from tests-phandle.dtsi */ -+ switch (i) { -+ case 0: -+ passed &= !rc; -+ passed &= (args.args_count == 1); -+ passed &= (args.args[0] == 9); -+ break; -+ case 1: -+ passed &= !rc; -+ passed &= (args.args_count == 3); -+ passed &= (args.args[0] == 10); -+ passed &= (args.args[1] == 11); -+ passed &= (args.args[2] == 12); -+ break; -+ case 2: -+ passed &= !rc; -+ passed &= (args.args_count == 2); -+ passed &= (args.args[0] == 13); -+ passed &= (args.args[1] == 14); -+ break; -+ case 3: -+ passed &= !rc; -+ passed &= (args.args_count == 2); -+ passed &= (args.args[0] == 15); -+ passed &= (args.args[1] == 16); -+ break; -+ default: -+ passed = false; -+ } -+ selftest(passed, "index %i - data error on node %s rc=%i\n", -+ i, args.np->full_name, rc); -+ } -+ of_node_put(np); -+} -+ -+static void __init of_selftest_parse_interrupts_extended(void) -+{ -+ struct device_node *np; -+ struct of_phandle_args args; -+ int i, rc; -+ -+ np = of_find_node_by_path("/testcase-data/interrupts/interrupts-extended0"); -+ if (!np) { -+ pr_err("missing testcase data\n"); -+ return; -+ } -+ -+ for (i = 0; i < 7; i++) { -+ bool passed = true; -+ rc = of_irq_parse_one(np, i, &args); -+ -+ /* Test the values from tests-phandle.dtsi */ -+ switch (i) { -+ case 0: -+ passed &= !rc; -+ passed &= (args.args_count == 1); -+ passed &= (args.args[0] == 1); -+ break; -+ case 1: -+ passed &= !rc; -+ passed &= (args.args_count == 3); -+ passed &= (args.args[0] == 2); -+ passed &= (args.args[1] == 3); -+ passed &= (args.args[2] == 4); -+ break; -+ case 2: -+ passed &= !rc; -+ passed &= (args.args_count == 2); -+ passed &= (args.args[0] == 5); -+ passed &= (args.args[1] == 6); -+ break; -+ case 3: -+ passed &= !rc; -+ passed &= (args.args_count == 1); -+ passed &= (args.args[0] == 9); -+ break; -+ case 4: -+ passed &= !rc; -+ passed &= (args.args_count == 3); -+ passed &= (args.args[0] == 10); -+ passed &= (args.args[1] == 11); -+ passed &= (args.args[2] == 12); -+ break; -+ case 5: -+ passed &= !rc; -+ passed &= (args.args_count == 2); -+ passed &= (args.args[0] == 13); -+ passed &= (args.args[1] == 14); -+ break; -+ case 6: -+ passed &= !rc; -+ passed &= (args.args_count == 1); -+ passed &= (args.args[0] == 15); -+ break; -+ default: -+ passed = false; -+ } -+ -+ selftest(passed, "index %i - data error on node %s rc=%i\n", -+ i, args.np->full_name, rc); -+ } -+ of_node_put(np); -+} -+ - static int __init of_selftest(void) - { - struct device_node *np; -@@ -168,7 +309,10 @@ static int __init of_selftest(void) - pr_info("start of selftest - you will see error messages\n"); - of_selftest_parse_phandle_with_args(); - of_selftest_property_match_string(); -- pr_info("end of selftest - %s\n", selftest_passed ?
