[ Upstream commit 5eb316e6 ] Add support for the IIC code for the r8a77990 (R-Car E3). It is not considered compatible with existing fallback bindings due to the documented absence of automatic transmission registers. These registers are currently not used by the driver and thus the provides the same behaviour for "renesas,iic-r8a77990" and "renesas,rcar-gen3-iic". The point of declaring incompatibility is to allow for automatic transmission register support to be added to "renesas,iic-r8a77990" and "renesas,rcar-gen3-iic" in future. Signed-off-by:

[ Upstream commit 2912289a ] The v4l2_dv_timings_cap struct is used to do sanity checks when setting and enumerating DV timings, ensuring that only valid timings as per the HW capabilities are allowed. However, many drivers just filled in 0 for the minimum width, height or pixelclock frequency. This can cause timings with e.g. 0 as width and height to be accepted, which will in turn lead to a potential division by zero. Fill in proper values are minimum boundaries. 640x350 was chosen since it is the smallest resolution in v4l2-dv-timings.h. Same for 13 MHz as the lowest pixelclock frequency (it's slightly below the minimum of 13.5 MHz in the v4l2-dv-timings.h header). Signed-off-by:

The KIOX010A HID is for the one in the base and the KIOX020A for the accelerometer in the keyboard. Since userspace does not have a way yet to deal with (or ignore) the accelerometer in the keyboard, this commit just adds the KIOX010A HID for now so that display rotation will work.

[ Upstream commit 50314f98 ] Before this patch we are registering the internal clocks (for example on Meson8b, where the SAR ADC IP block implements the divider and gate clocks) with the following names: - /soc/cbus@c1100000/adc@8680#adc_div - /soc/cbus@c1100000/adc@8680#adc_en This is bad because the common clock framework uses the clock to create a directory in <debugfs>/clk. With such name, the directory creation (silently) fails and the debugfs entry ends up being created at the debugfs root. With this change, the new clock names are: - c1108680.adc#adc_div - c1108680.adc#adc_en This matches the clock naming scheme used in the PWM, Ethernet and MMC drivers. It also fixes the problem with debugfs. The idea is shamelessly taken from commit b96e9eb6 ("pwm: meson: Fix mux clock names").

[ Upstream commit fa68d4f8 ] Some of the functions (like cdn_dp_dpcd_read, cdn_dp_get_edid_block) allow to read 64KiB, but the cdn_dp_mailbox_read_receive, that is used by them, can read only up to 255 bytes at once. Normally, it's not a big issue as DPCD or EDID reads won't (hopefully) exceed that value. The real issue here is the revocation list read during the HDCP authentication process. (problematic use case: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/gpu/drm/rockchip/cdn-dp-reg.c#1152) The list can reach 127*5+4 bytes (num devs * 5 bytes per ID/Bksv + 4 bytes of an additional info). In other words - CTSes with HDCP Repeater won't pass without this fix. Oh, and the driver will most likely stop working (best case scenario). Signed-off-by:

[ Upstream commit 6ad16b78 ] EC_MKBP_EVENT_SENSOR_FIFO events can be triggered for a variety of reasons, and there are very few cases in which they should be treated as wakeup interrupts (particularly, when a certain MOTIONSENSE_MODULE_FLAG_* is set, but this is not even supported in the mainline cros_ec_sensor driver yet). Most of the time, they are benign sensor readings. In any case, the top-level cros_ec device doesn't know enough to determine that they should wake the system, and so it should not report the event. This would be the job of the cros_ec_sensors driver to parse. This patch adds checks to cros_ec_get_next_event() such that it doesn't signal 'wakeup' for events of type EC_MKBP_EVENT_SENSOR_FIFO. This patch is particularly relevant on devices like Scarlet (Rockchip RK3399 tablet, known as Acer Chromebook Tab 10), where the EC firmware reports sensor events much more frequently. This was causing /sys/power/wakeup_count to increase very frequently, often needlessly interrupting our ability to suspend the system. Signed-off-by:

[ Upstream commit 5ec17af7 ] The Intel EG20T Platform Controller Hub used on the MIPS Boston development board supports prefetching memory to optimize DMA transfers. Unfortunately for unknown reasons this doesn't work well with some MIPS CPUs such as the P6600, particularly when using an I/O Coherence Unit (IOCU) to provide cache-coherent DMA. In these systems it is common for DMA data to be lost, resulting in broken access to EG20T devices such as the MMC or SATA controllers. Support for a DT property to configure the prefetching was added a while back by commit 549ce8f1 ("misc: pch_phub: Read prefetch value from device tree if passed") but we never added the DT snippet to make use of it. Add that now in order to disable the prefetching & fix DMA on the affected systems. Signed-off-by:

[ Upstream commit 0a6a40c2 ] In the "aes-fixed-time" AES implementation, disable interrupts while accessing the S-box, in order to make cache-timing attacks more difficult. Previously it was possible for the CPU to be interrupted while the S-box was loaded into L1 cache, potentially evicting the cachelines and causing later table lookups to be time-variant. In tests I did on x86 and ARM, this doesn't affect performance significantly. Responsiveness is potentially a concern, but interrupts are only disabled for a single AES block. Note that even after this change, the implementation still isn't necessarily guaranteed to be constant-time; see https://cr.yp.to/antiforgery/cachetiming-20050414.pdf for a discussion of the many difficulties involved in writing truly constant-time AES software. But it's valuable to make such attacks more difficult. Reviewed-by:

[ Upstream commit 30e196ca ] After a LOGO in response to an ABTS timeout, a PLOGI wasn't issued to re-establish the login. An nlp_type check in the LOGO completion handler failed to restart discovery for NVME targets. Revised the nlp_type check for NVME as well as SCSI. While reviewing the LOGO handling a few other issues were seen and were addressed: - Better lock synchronization around ndlp data types - When the ABTS times out, unregister the RPI before sending the LOGO so that all local exchange contexts are cleared and nothing received while awaiting LOGO/PLOGI handling will be accepted. - LOGO handling optimized to: Wait only R_A_TOV for a response. It doesn't need to be retried on timeout. If there wasn't a response, a PLOGI will be sent, thus an implicit logout applies as well when the other port sees it. If there is a response, any kind of response is considered "good" and the XRI quarantined for a exchange qualifier window. - PLOGI is issued as soon a LOGO state is resolved. Signed-off-by:

[ Upstream commit 819bec35 ] Prevent possible race by parallel threads between ipu_image_convert_run() and ipu_image_convert_unprepare(). This involves setting ctx->aborting to true unconditionally so that no new job runs can be queued during unprepare, and holding the ctx->aborting flag until the context is freed. Note that the "normal" ipu_image_convert_abort() case (e.g. not during context unprepare) should clear the ctx->aborting flag after aborting any active run and clearing the context's pending queue. This is because it should be possible to continue to use the conversion context and queue more runs after an abort. Signed-off-by:
