Allow users to interact with one as a uio device. Signed-off-by: Chris Packham --- Changes in v3: - (replaces "uio: add default compatible string to uio_pdrv_genirq") - remove superfluous change suggested by checkpatch.pl - As suggested by Rob, add specific dt bindings for the hardware I'm supporting. uio_pdrv_genirq is one potential implementor of a compatible driver. drivers/uio/uio_pdrv_genirq.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/uio/uio_pdrv_genirq.c b/drivers/uio/uio_pdrv_genirq.c index f598ecddc8a7..532de98034c2 100644 --- a/drivers/uio/uio_pdrv_genirq.c +++ b/drivers/uio/uio_pdrv_genirq.c @@ -253,11 +253,12 @@ static const struct dev_pm_ops uio_pdrv_genirq_dev_pm_ops = { #ifdef CONFIG_OF static struct of_device_id uio_of_genirq_match[] = { + { .compatible = "st,stm32f100" }, { /* This is filled with module_parm */ }, { /* Sentinel */ }, }; MODULE_DEVICE_TABLE(of, uio_of_genirq_match); -module_param_string(of_id, uio_of_genirq_match[0].compatible, 128, 0); +module_param_string(of_id, uio_of_genirq_match[1].compatible, 128, 0); MODULE_PARM_DESC(of_id, "Openfirmware id of the device to be handled by uio"); #endif -- 2.14.2
