nvmem: Add driver for the i.MX IIM

2017-04-08T15:51:48+00:00

This adds a readonly nvmem driver for the i.MX IC Identification Module (IIM). The IIM is found on the older i.MX SoCs like the i.MX25, i.MX27, i.MX31, i.MX35, i.MX51 and the i.MX53. The IIM can control up to 8 fuse banks with 256 bit each. Not all of the banks are equipped on the different SoCs. The actual number of fuses differ from 512 on the i.MX27 and 1152 on the i.MX53. The fuses are one time writable, but writing is currently not supported in the driver.

nvmem: Add the Broadcom OTP controller driver

2016-11-10T14:34:56+00:00

Add support for 32 and 64-bit versions of Broadcom's On-Chip OTP controller. These controllers are used on SoC's such as Cygnus and Stingray.

nvmem: add NXP LPC18xx OTP driver

2016-11-10T14:34:55+00:00

Add simple read only driver for the internal OTP (One Time Programmable) memory found on all NXP LPC18xx and LPC43xx devices. The OTP memory is split into 4 banks each with 4 32-bits word. Some of the banks contain predefined data while others are for general purpose and user programmable via the OTP API in ROM. Note that writing to the OTP memory is not yet supported.

nvmem: imx-ocotp: add COMPILE_TEST for proper test coverage

2016-06-25T14:42:55+00:00

This patch add COMPILE_TEST to imx-ocotp driver so that it can be compile tested on other platforms with zero day testing. Also adds HAS_IOMEM dependancy as the users of devm_ioremap_resource() which are compile-testable should depend on HAS_IOMEM.

nvmem: mtk-efuse: remove nvmem regmap dependency

2016-06-25T14:42:55+00:00

Regmap raw accessors are bus specific implementations, using regmap raw apis in nvmem breaks nvmem providers based on regmap mmio. This patch moves to nvmem support in the driver to use callback instead of regmap, which is what the nvmem core supports now. Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

nvmem: core: remove regmap dependency

2016-05-01T21:01:00+00:00

nvmem uses regmap_raw_read/write apis to read/write data from providers, regmap raw apis stopped working with recent kernels which removed raw accessors on mmio bus. This resulted in broken nvmem for providers which are based on regmap mmio bus. This issue can be fixed temporarly by moving to other regmap apis, but we might hit same issue in future. Moving to interfaces based on read/write callbacks from providers would be more robust. This patch removes regmap dependency from nvmem and introduces read/write callbacks from the providers. Without this patch nvmem providers like qfprom based on regmap mmio bus would not work. Reported-by: Rajendra Nayak Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman
