Note this is currently in Linus' master tree, so any fixes to it need to be submitted on top (not that I expect any issues since it still behaves as before on acpi_dev_gpio_irq_get() success and only adds an platform_get_irq() fallback when that fails). > > Regards, > > Hans > > > > > --- > > drivers/acpi/scan.c | 1 + > > drivers/platform/x86/serial-multi-instantiate.c | 12 ++++++++++++ > > 2 files changed, 13 insertions(+) > > > > diff --git a/drivers/acpi/scan.c b/drivers/acpi/scan.c > > index 5b145f1aaa1b..87e385542576 100644 > > --- a/drivers/acpi/scan.c > > +++ b/drivers/acpi/scan.c > > @@ -1714,6 +1714,7 @@ static bool acpi_device_enumeration_by_parent(struct acpi_device *device) > > {"BSG1160", }, > > {"BSG2150", }, > > {"CSC3551", }, > > + {"CSC3556", }, > > {"INT33FE", }, > > {"INT3515", }, > > /* Non-conforming _HID for Cirrus Logic already released */ > > diff --git a/drivers/platform/x86/serial-multi-instantiate.c b/drivers/platform/x86/serial-multi-instantiate.c > > index f3dcbdd72fec..dcf2914b97c9 100644 > > --- a/drivers/platform/x86/serial-multi-instantiate.c > > +++ b/drivers/platform/x86/serial-multi-instantiate.c > > @@ -316,6 +316,17 @@ static const struct smi_node cs35l41_hda = { > > .bus_type = SMI_AUTO_DETECT, > > }; > > > > +static const struct smi_node cs35l56_hda = { > > + .instances = { > > + { "cs35l56-hda", IRQ_RESOURCE_GPIO, 0 }, > > + { "cs35l56-hda", IRQ_RESOURCE_GPIO, 0 }, > > + { "cs35l56-hda", IRQ_RESOURCE_GPIO, 0 }, > > + { "cs35l56-hda", IRQ_RESOURCE_GPIO, 0 }, > > + {} > > + }, > > + .bus_type = SMI_AUTO_DETECT, > > +}; > > + > > /* > > * Note new device-ids must also be added to ignore_serial_bus_ids in > > * drivers/acpi/scan.c: acpi_device_enumeration_by_parent(). > > @@ -324,6 +335,7 @@ static const struct acpi_device_id smi_acpi_ids[] = { > > { "BSG1160", (unsigned long)&bsg1160_data }, > > { "BSG2150", (unsigned long)&bsg2150_data }, > > { "CSC3551", (unsigned long)&cs35l41_hda }, > > + { "CSC3556", (unsigned long)&cs35l56_hda }, > > { "INT3515", (unsigned long)&int3515_data }, > > /* Non-conforming _HID for Cirrus Logic already released */ > > { "CLSA0100", (unsigned long)&cs35l41_hda }, >
