This changeset adds write support to meson efuse driver. The first patch just changes the way the nvmem data are allocated w/o any functional changes. The second patches actually adds write support.
The memory being an OTP, it is safer if it remains read-only by default, which is why I also submitted this DT patch [0]. It has now been merged by Kevin. If a user knows what he is doing, it should be easy to remove the read-only property from the board DT. This can be done in u-boot, before starting linux: > fdt rm /efuse read-only Tested on the gxl libretech-cc Changes since v1 [1]: - Remove un-necessary code in callbacks - Rebase on v4.17-rc1 [0]: https://lkml.kernel.org/r/[email protected] [1]: https://lkml.kernel.org/r/[email protected] Jerome Brunet (3): nvmem: meson-efuse: remove econfig global nvmem: meson-efuse: simplify read callback nvmem: meson-efuse: add write support drivers/nvmem/meson-efuse.c | 41 ++++++++++++++++++++++------------------- 1 file changed, 22 insertions(+), 19 deletions(-) -- 2.14.3
