This patch deletes the virtio functionality from the MIC X100 card driver. A subsequent patch will re-enable this functionality by consolidating the hardware independent logic in a new Virtio over PCIe (VOP) driver. Reviewed-by:

The file wd.c was remove from the driver by commit commit fdd9b865 ("mei: wd: drop the watchdog code from the core mei driver") Unfortunately it came back by mistake in rebasing in the commit commit 06ee536b ("mei: fill file pointer in read cb for fixed address client") Signed-off-by:

The kernel sometimes fails to link when lkdrm is built-in and compiled with clang: relocation truncated to fit: R_ARM_THM_CALL against `.bss' The reason here is that a relocation from .text to .bss fails to generate a trampoline because .bss is not an executable section. Marking the function 'noinline' turns the relative branch to .bss into an absolute branch to the function argument, and that works fine. Signed-off-by:

This commit documents bindings to be added to the eeprom_93xx46 driver which will allow: - Device word size and read-only attributes to be specified. - A device-specific compatible string for use with Atmel AT93C46D EEPROMs. - Specifying a GPIO line to function as a 'select' or 'enable' signal prior to accessing the EEPROM.

Compatible at93xx46 devices from both Microchip and Atmel expect a word-based address, regardless of whether the device is strapped for 8- or 16-bit operation. However, the offset parameter passed in when reading or writing at a specific location is always specified in terms of bytes. This commit fixes 16-bit read and write accesses by shifting the offset parameter to account for this difference between a byte offset and a word-based address. Signed-off-by:

Compat ioctl is already introduced in drivers/char/ppdev.c in order to fix y2038 issue for PP[GS]ETTIME. There is no need to define these here. Suggested-by:

The arg of ioctl in ppdev is the pointer of integer except the timeval in PPSETTIME, PPGETTIME. Different size of timeval is already supported by the previous patches. So, it is safe to add compat support. Signed-off-by:

Bamvor Jian Zhang authored
The y2038 issue for ppdev is changes of timeval in the ioctl (PPSETTIME and PPGETTIME). The size of struct timeval changes from 8bytes to 16bytes due to the changes of time_t. It lead to the changes of the command of ioctl, e.g. for PPGETTIME, We have: on 32-bit (old): 0x80087095 on 32-bit (new): 0x80107095 on 64-bit : 0x80107095 This patch define these two ioctl commands to support the 32bit and 64bit time_t application at the same time. And, introduce pp_set_timeout to remove some duplicated code. Signed-off-by:

Simplify a few of the *generic* shared dev_warn() and dev_dbg() print messages for three reasons: 0) Historically firmware_class code was added to help get device driver firmware binaries but these days request_firmware*() helpers are being repurposed for general *system data* needed by the kernel. 1) This will also help generalize shared code as much as possible later in the future in consideration for a new extensible firmware API which will enable to separate usermode helper code out as much as possible. 2) Kees Cook pointed out the the prints already have the device associated as dev_*() helpers are used, that should help identify the user and case in which the helpers are used. That should provide enough context and simplifies the messages further. v4: generalize debug/warn messages even further as suggested by Kees Cook.

Add support for more than 128 peripherals by taking a lazy caching approach to the mapping tables. Instead of reading and caching the tables at boot given some fixed size, read them and cache them on an as needed basis. We still assume a max size of 512 peripherals, trading off some space for simplicity. Based on a patch by Gilad Avidov <gavidov@codeaurora.org> and Sagar Dharia <sdharia@codeaurora.org>.

nvmem providers have restrictions on register strides, so return error when users attempt to read/write buffers with sizes which are less than word size. Without this patch the userspace would continue to try as it does not get any error from the nvmem core, resulting in a hang or endless loop in userspace. Reported-by:

This commit adds support for NXP LPC18xx EEPROM memory found in NXP LPC185x/3x and LPC435x/3x/2x/1x devices. EEPROM size is 16384 bytes and it can be entirely read and written/erased with 1 word (4 bytes) granularity. The last page (128 bytes) contains the EEPROM initialization data and is not writable. Erase/program time is less than 3ms. The EEPROM device requires a ~1500 kHz clock (min 800 kHz, max 1600 kHz) that is generated dividing the system bus clock by the division factor, contained in the divider register (minus 1 encoded). EEPROM will be kept in Power Down mode except during read/write calls. Signed-off-by:

Commit 985087db 'misc: add support for bmp18x chips to the bmp085 driver' changed the BMP085 config symbol to a boolean.

The Kconfig currently controlling compilation of this code is: drivers/misc/Kconfig:config ARM_CHARLCD drivers/misc/Kconfig: bool "ARM Ltd. Character LCD Driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and this driver did not have a ".remove" function coded for non-modular drivers either. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We don't replace module.h with init.h since the file already has that. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
