nvmem: sfp: Add support for TA 2.1 devices

2022-05-09T13:46:29Z

This adds support for Trust Architecture (TA) 2.1 devices to the SFP driver. There are few differences between TA 2.1 and TA 3.0, especially for read-only support, so just re-use the existing data.

nvmem: sfp: Use regmap

2022-05-09T13:46:29Z

This converts the SFP driver to use regmap. This will allow easily supporting devices with different endians. We disallow byte-level access, as regmap_bulk_read doesn't support it (and it's unclear what the correct result would be when we have an endianness difference).

nvmem: qfprom: using pm_runtime_resume_and_get instead of pm_runtime_get_sync

2022-05-09T13:45:39Z

Using pm_runtime_resume_and_get is more appropriate for simplifing code Reported-by: Zeal Robot Signed-off-by: Minghao Chi Signed-off-by: Srinivas Kandagatla Link: https://lore.kernel.org/r/20220429162701.2222-10-srinivas.kandagatla@linaro.org Signed-off-by: Greg Kroah-Hartman

nvmem: Add Apple eFuse driver

2022-05-09T13:44:21Z

Apple SoCs contain eFuses used to store factory-programmed data such as calibration values for the PCIe or the Type-C PHY. They are organized as 32bit values exposed as MMIO.

nvmem: brcm_nvram: find Device Tree nodes for NVMEM cells

2022-05-09T13:44:21Z

DT binding for Broadcom's NVRAM supports specifying NVMEM cells as NVMEM device (provider) subnodes. Look for such subnodes when collecing NVMEM cells. This allows NVMEM consumers to use NVRAM variables.

nvmem: core: support passing DT node in cell info

2022-05-09T13:44:21Z

Some hardware may have NVMEM cells described in Device Tree using individual nodes. Let drivers pass such nodes to the NVMEM subsystem so they can be later used by NVMEM consumers.

nvmem: sunplus-ocotp: drop useless probe confirmation

2022-04-24T15:15:15Z

Printing probe success is discouraged, because we can use tracing for this purpose. Remove useless print message after Sunplus OCOTP driver probe. Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20220321110326.44652-3-krzk@kernel.org Signed-off-by: Greg Kroah-Hartman

nvmem: sunplus-ocotp: staticize sp_otp_v0

2022-04-24T15:15:14Z

The "sp_otp_v0" file scope variable is not used outside, so make it static to fix warning: drivers/nvmem/sunplus-ocotp.c:74:29: sparse: sparse: symbol 'sp_otp_v0' was not declared.
