2019-09-16nvmem: sunxi_sid: Support SID on A83T and H5Chen-Yu Tsai
commit da75b8909756160b8e785104ba421a20b756c975 upstream. The device tree binding already lists compatible strings for these two SoCs. They don't have the defect as seen on the H3, and the size and register layout is the same as the A64. Furthermore, the driver does not include nvmem cell definitions. Add support for these two compatible strings, re-using the config for the A64.

2019-09-16nvmem: core: fix read buffer in placeJorge Ramirez-Ortiz
commit 2fe518fecb3a4727393be286db9804cd82ee2d91 upstream. When the bit_offset in the cell is zero, the pointer to the msb will not be properly initialized (ie, will still be pointing to the first byte in the buffer). This being the case, if there are bits to clear in the msb, those will be left untouched while the mask will incorrectly clear bit positions on the first byte. This commit also makes sure that any byte unused in the cell is cleared.

2018-07-07nvmem: Don't let a NULL cell_id for nvmem_cell_get() crash usDouglas Anderson
In commit ca04d9d3e1b1 ("phy: qcom-qusb2: New driver for QUSB2 PHY on Qcom chips") you can see a call like: devm_nvmem_cell_get(dev, NULL); Note that the cell ID passed to the function is NULL. This is because the qcom-qusb2 driver is expected to work only on systems where the PHY node is hooked up via device-tree and is nameless. This works OK for the most part. The first thing nvmem_cell_get() does is to call of_nvmem_cell_get() and there it's documented that a NULL name is fine. The problem happens when the call to of_nvmem_cell_get() returns -EINVAL. In such a case we'll fall back to nvmem_cell_get_from_list() and eventually might (if nvmem_cells isn't an empty list) crash with something that looks like: strcmp nvmem_find_cell __nvmem_device_get nvmem_cell_get_from_list nvmem_cell_get devm_nvmem_cell_get qusb2_phy_probe There are several different ways we could fix this problem: One could argue that perhaps the qcom-qusb2 driver should be changed to use of_nvmem_cell_get() which is allowed to have a NULL name. In that case, we'd need to add a patche to introduce devm_of_nvmem_cell_get() since the qcom-qusb2 driver is using devm managed resources. One could also argue that perhaps we could just add a name to qcom-qusb2. That would be OK but I believe it effectively changes the device tree bindings, so maybe it's a no-go. In this patch I have chosen to fix the problem by simply not crashing when a NULL cell_id is passed to nvmem_cell_get(). NOTE: that for the qcom-qusb2 driver the "nvmem-cells" property is defined to be optional and thus it's expected to be a common case that we would hit this crash and this is more than just a theoretical fix.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-04-04nvmem: disallow modular CONFIG_NVMEMArnd Bergmann
The new of_get_nvmem_mac_address() helper function causes a link error with CONFIG_NVMEM=m: drivers/of/of_net.o: In function `of_get_nvmem_mac_address': of_net.c:(.text+0x168): undefined reference to `of_nvmem_cell_get' of_net.c:(.text+0x19c): undefined reference to `nvmem_cell_read' of_net.c:(.text+0x1a8): undefined reference to `nvmem_cell_put' I could not come up with a good solution for this, as the code is always built-in. Using an #if IS_REACHABLE() check around it would solve the link time issue but then stop it from working in that configuration. Making of_nvmem_cell_get() an inline function could also solve that, but seems a bit ugly since it's somewhat larger than most inline functions, and it would just bring that problem into the callers. Splitting the function into a separate file might be an alternative. This uses the big hammer by making CONFIG_NVMEM itself a 'bool' symbol, which avoids the problem entirely but makes the vmlinux larger for anyone that might use NVMEM support but doesn't need it built-in otherwise.

2017-12-23nvmem: meson-mx-efuse: fix reading from an offset other than 0Martin Blumenstingl
meson_mx_efuse_read calculates the address internal to the eFuse based on the offset and the word size. This works fine with any given offset. However, the offset is also included when writing to the output buffer. This means that reading 4 bytes at offset 500 tries to write beyond the array allocated by the nvmem core as it wants to write the 4 bytes to "buffer address + offset (500)". This issue did not show up in the previous tests since no driver uses any value from the eFuse yet and reading the eFuse via sysfs simply reads the whole eFuse, starting at offset 0. Fix this by only including the offset in the internal address calculation.
