2021-05-14	nvmem: sprd: Fix an error message	Christophe JAILLET	1	-1/+1
	'ret' is known to be 0 here. The expected error status is stored in 'status', so use it instead. Also change %d in %u, because status is an u32, not a int.

2020-07-29	nvmem: sprd: Fix return value of sprd_efuse_probe()	Tiezhu Yang	1	-2/+2
	When call function devm_platform_ioremap_resource(), we should use IS_ERR() to check the return value and return PTR_ERR() if failed.

2020-03-23	nvmem: sprd: Determine double data programming from device data	Baolin Wang	1	-1/+2
	We've saved the double data flag in the device data, so we should use it when programming a block.

2020-03-23	nvmem: sprd: Optimize the block lock operation	Freeman Liu	1	-4/+20
	We have some cases that will programme the eFuse block partially multiple times, so we should allow the block to be programmed again if it was programmed partially. But we should lock the block if the whole block was programmed. Thus add a condition to validate if we need lock the block or not. Moreover we only enable the auto-check function when locking the block.

2020-03-23	nvmem: sprd: Fix the block lock operation	Freeman Liu	1	-1/+1
	According to the Spreadtrum eFuse specification, we should write 0 to the block to trigger the lock operation.

2019-11-05	nvmem: sprd: Add Spreadtrum SoCs eFuse support	Freeman Liu	1	-0/+424
	The Spreadtrum eFuse controller is widely used to dump chip ID, configuration setting, function select and so on, as well as supporting one-time programming.
