Signed-off-by: Cezary Rojewski Reviewed-by: Greg Kroah-Hartman --- Changes in v7: - fixed licence header for fs.c - renamed fs.c to sysfs.c to better match its purpose - added documentation within Documentation/ABI/testing for entries exposed by catpt - bin_attribute fw_build replaced by attribute fw_info: fw_info contains full FW information and after successful handshake, it's always available (stored in driver data) so no need to invoke GET_FW_VERSION IPC again, just dump the stored information - rather than manually creating and removing sysfs files, now makes use of dev_groups member of struct device_driver Changes in v6: - functions declaration and usage now part of this patch instead of being separated from it Changes in v2: - fixed size provided to memcpy() in fw_build_read() as reported by Mark .../ABI/testing/sysfs-bus-pci-devices-catpt | 16 ++++++ sound/soc/intel/catpt/core.h | 1 + sound/soc/intel/catpt/device.c | 1 + sound/soc/intel/catpt/sysfs.c | 57 +++++++++++++++++++ 4 files changed, 75 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-pci-devices-catpt create mode 100644 sound/soc/intel/catpt/sysfs.c diff --git a/Documentation/ABI/testing/sysfs-bus-pci-devices-catpt b/Documentation/ABI/testing/sysfs-bus-pci-devices-catpt new file mode 100644 index 000000000000..8a200f4eefbd --- /dev/null +++ b/Documentation/ABI/testing/sysfs-bus-pci-devices-catpt @@ -0,0 +1,16 @@ +What: /sys/devices/pci0000:00//fw_version +Date: September 2020 +Contact: Cezary Rojewski +Description: + Version of AudioDSP firmware ASoC catpt driver is + communicating with. + Format: %d.%d.%d.%d, type:major:minor:build. + +What: /sys/devices/pci0000:00//fw_info +Date: September 2020 +Contact: Cezary Rojewski +Description: + Detailed AudioDSP firmware build information including + build hash and log-providers hash.
