firmware: meson_sm: Rework driver as a proper platform driver

2019-10-03T15:43:33Z

The secure monitor driver is currently a frankenstein driver which is registered as a platform driver but its functionality goes through a global struct accessed by the consumer drivers using exported helper functions. Try to tidy up the driver moving the firmware struct into the driver data and make the consumer drivers referencing the secure-monitor using a new property in the DT. Currently only the nvmem driver is using this API so we can fix it in the same commit. Reviewed-by: Jerome Brunet Signed-off-by: Carlo Caione Signed-off-by: Kevin Hilman

firmware: meson_sm: Add serial number sysfs entry

firmware: meson-sm: rework meson_sm_init to use module_platform_driver_probe

2018-03-08T01:33:52Z

Commit 3aa0582fdb82 ("of: platform: populate /firmware/ node from of_platform_default_populate_init()") takes care of populating all the devices under the /firmware/ node in of_platform_default_populate_init() This patch reworks meson_sm_init to use module_platform_driver_probe as the platform device is populated.

firmware: meson-sm: Allow 0 as valid return value

2017-03-23T19:22:40Z

Some special SMC calls (i.e. the function used to retrieve the serial number of the Amlogic SoCs) returns 0 in the register 0 also when the data was successfully read instead of using the register to hold the number of bytes returned in the bounce buffer as expected. With the current implementation of the driver this is seen as an error and meson_sm_call_read() returns an error even though the data was correctly read. To deal with this when we have no information about the amount of read data (that is 0 is returned by the SMC call) we return to the caller the requested amount of data and 0 as return value.
