* crypto: atmel-aes - add support to the XTS modeCyrille Pitchen2016-10-212-6/+183
| | | | | | | | This patch adds the xts(aes) algorithm, which is supported from hardware version 0x500 and above (sama5d2x). Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: atmel-aes - fix compiler error when VERBOSE_DEBUG is definedCyrille Pitchen2016-10-211-1/+1
| | | | | | | | | | This patch fixes a compiler error when VERBOSE_DEBUG is defined. Indeed, in atmel_aes_write(), the 3rd argument of atmel_aes_reg_name() was missing.

* hwrng: omap - Don't prefix the probe message with OMAPRomain Perier2016-10-211-1/+1
| | | | | | | | | | | | | So far, this driver was only used for OMAP SoCs. However, if a device variant is added for an IP block that has nothing to do with the OMAP platform, the message "OMAP Random Number Generator Ver" is displayed anyway. Instead of hardcoding "OMAP" into this message, we decide to only display "Random Number Generator". As dev_info is already pre-pending the message with the name of the device, we have enough informations.

* hwrng: omap - Add support for 128-bit output of dataRomain Perier2016-10-211-6/+8
| | | | | | | | | | | | So far, this driver only supports up to 64 bits of output data generated by an RNG. Some IP blocks, like the SafeXcel IP-76 supports up to 128 bits of output data. This commits renames registers descriptions OUTPUT_L_REG and OUTPUT_H_REG to OUTPUT_0_REG and OUPUT_1_REG, respectively. It also adds two new values to the enumeration of existing registers: OUTPUT_2_REG and OUTPUT_3_REG.

* hwrng: omap - Remove global definition of hwrngRomain Perier2016-10-211-9/+14
| | | | | | | | | | | | | The omap-rng driver currently assumes that there will only ever be a single instance of an RNG device. For this reason, there is a statically allocated struct hwrng, with a fixed name. However, registering two struct hwrng with the same isn't accepted by the RNG framework, so we need to switch to a dynamically allocated struct hwrng, each using a different name. Then, we define the name of this hwrng to "dev_name(dev)", so the name of the data structure is unique per device.

* hwrng: omap - Switch to non-obsolete read API implementationRomain Perier2016-10-211-24/+17
| | | | | | | | | | | | | | The ".data_present" and ".data_read" operations are marked as OBSOLETE in the hwrng API. We have to use the ".read" operation instead. It makes the driver simpler and moves the busy loop, that waits until enough data is generated, to the read function. We simplify this step by only checking the status of the engine, if there is data, we copy the data to the output buffer and the amout of copied data is returned to the caller, otherwise zero is returned. The hwrng core will re-call the read operation as many times as required until enough data has been copied.

It is designed to extract as much possible uncertainty from a running system at boot time as possible, hoping to capitalize on any possible variation in CPU operation (due to runtime data differences, hardware differences, SMP ordering, thermal timing variation, cache behavior, etc). At the very least, this plugin is a much more comprehensive example for how to manipulate kernel code using the gcc plugin internals" * tag 'gcc-plugins-v4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: latent_entropy: Mark functions with __latent_entropy gcc-plugins: Add latent_entropy plugin

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The __latent_entropy gcc attribute can be used only on functions and variables. If it is on a function then the plugin will instrument it for gathering control-flow entropy. If the attribute is on a variable then the plugin will initialize it with random contents. The variable must be an integer, an integer array type or a structure with integer fields. These specific functions have been selected because they are init functions (to help gather boot-time entropy), are called at unpredictable times, or they have variable loops, each of which provide some level of latent entropy.

| * | of/platform: Probe "isa" busses by defaultPaul Burton2016-10-061-0/+1

The MIPS Malta board needs to probe devices under an ISA bus, which we do support in the of_busses array but until now haven't included in of_default_bus_match_table. Add an "isa" entry to of_default_bus_match_table such that we can just accept use of of_platform_default_populate_init & remove the Malta-specific match table in a later patch.

| * | irqchip: i8259: Allow platforms to override poll functionPaul Burton2016-10-061-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default i8259 polling function (i8259_irq) is nicely generic but is fairly costly. Platforms often provide an alternative means of polling for an i8259 interrupt, and when using the i8259 without device tree have typically just chained its parent interrupt to their own handler function. In order to allow for platform-specific polling functions to be used in cases where the driver is probed via device tree, provide an i8259_set_poll function that accepts a pointer to an alternative poll function that will override the default.

| * | irqchip: i8259: Add domain before mapping parent irqPaul Burton2016-10-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mapping the parent IRQ will use a virq number which may conflict with the hardcoded I8259A_IRQ_BASE..I8259A_IRQ_BASE+15 range that the i8259 driver expects to be free. If this occurs then we'll hit errors when adding the i8259 IRQ domain, since one of its virq numbers will already be in use. Avoid this by adding the i8259 domain before mapping the parent IRQ, such that the i8259 virq numbers become used before the parent interrupt controller gets a chance to use any of them.

| * | auxdisplay: img-ascii-lcd: driver for simple ASCII LCD displaysPaul Burton2016-10-063-0/+453
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a driver for simple ASCII LCD displays found on the MIPS Boston, Malta & SEAD3 development boards. The Boston display is an independent memory mapped device with a simple memory mapped 8 byte register space containing the 8 ASCII characters to display. The Malta display is exposed as part of the Malta board registers, and provides 8 registers each of which corresponds to one of the ASCII characters to display. The SEAD3 display is slightly more complex, exposing an interface to an S6A0069 LCD controller via registers provided by the boards CPLD. However although the displays differ in their register interface, we require similar functionality on each board so abstracting away the differences within a single driver allows us to share a significant amount of code & ensure consistent behaviour. The driver displays the Linux kernel version as the default message, but allows the message to be changed via a character device. Messages longer then the number of characters that the display can show will scroll. This provides different behaviour to the existing LCD display code for the MIPS Malta or MIPS SEAD3 platforms in the following ways: - The default string to display is not "LINUX ON MALTA" or "LINUX ON SEAD3" but "Linux" followed by the version number of the kernel (UTS_RELEASE). - Since that string tends to be significantly longer it scrolls twice as fast, moving every 500ms rather than every 1s. - The LCD won't be updated until the driver is probed, so it doesn't provide the early "LINUX" string.

Hence this patch also includes changes to remove CONFIG_BUILD_DOCSRC from Makefile and lib/Kconfig.debug and updates VIDEO_PCI_SKELETON dependency on BUILD_DOCSRC. Documentation/Makefile is not deleted to avoid braking make htmldocs and make distclean.

I ended up only having the time to complete one of the additional drivers. During Dave Miller's pull request this go around, there were a series of 9 patches to the QLogic qed net driver that add basic support for a paired RoCE driver. That support is currently not functional because it is missing the matching RoCE driver in the RDMA subsystem. I managed to finish that review. However, because it goes against part of Dave's net pull, and a part that was accepted a day or two after the merge window opened, to apply cleanly it has to be applied to either the tip of Dave's net branch, or as I did in this case, I just applied it to your master after you had taken Dave's pull request." * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: qedr: Add events support and register IB device qedr: Add GSI support qedr: Add LL2 RoCE interface qedr: Add support for data path qedr: Add support for memory registeration verbs qedr: Add support for QP verbs qedr: Add support for PD,PKEY and CQ verbs qedr: Add support for user context verbs qedr: Add support for RoCE HW init qedr: Add RoCE driver framework

They didn't do horribly, but there were some issues (and we knew that because they simply didn't know what to do in the beginning). As a result, I had a set of patches that depended on some patches that normally would have come to you via Dave's tree. Those patches have been on netdev@ for a while, so I got Dave to give me his approval to send them to you. As such, the other 29 patches I had behind them are also now ready to go. This catches the hns and hns-roce drivers up to current, and for future patches we are working with them to get them up to speed on how to do joint driver development so that they don't have these sorts of cross tree dependency issues again. BTW, Dave gave me permission to add his Acked-by: to the patches against the net tree, but I've had this branch through 0day (but not linux-next since it was off by itself) and I didn't want to rebase the series just to add Dave's ack for the 8 patches in the net area.
