Merge tag 'drm-for-v4.14' into dev-4.13

2018-04-19T02:00:20+00:00

This is the DRM tree that was merged into the mainline 4.14 kernel. The ASPEED GFX DRM driver requires functionaliy that was included in this tree, so we merge it back into the 4.13 OpenBMC tree. This should have no impact on other parts of the BMC. Signed-off-by: Joel Stanley

serial/8250: export serial8250_read_char

2018-04-05T13:18:55+00:00

Currently, we export serial8250_rx_chars, which does a whole bunch of reads from the 8250 data register, without any form of flow control between reads. An upcoming change to the aspeed vuart driver implements more fine-grained flow control in the interrupt handler, requiring character-at-a-time control over the rx path. This change exports serial8250_read_char to allow this. OpenBMC-Staging-Count: 1 Signed-off-by: Jeremy Kerr Tested-by: Eddie James Signed-off-by: Andrew Jeffery

serial: Introduce UPSTAT_SYNC_FIFO for synchronised FIFOs

2018-04-05T13:18:49+00:00

This change adds a flag to indicate that a UART is has an external means of synchronising its FIFO, without needing CTSRTS or XON/XOFF. This allows us to use the throttle/unthrottle callbacks, without having to claim other methods of flow control.

gpio: gpiolib: Generalise state persistence beyond sleep

2018-02-08T06:04:00+00:00

General support for state persistence is added to gpiolib with the introduction of a new pinconf parameter to propagate the request to hardware. The existing persistence support for sleep is adapted to include hardware support if the GPIO driver provides it. Persistence continues to be enabled by default; in-kernel consumers can opt out, but userspace (currently) does not have a choice. The *_SLEEP_MAY_LOSE_VALUE and *_SLEEP_MAINTAIN_VALUE symbols are renamed, dropping the SLEEP prefix to reflect that the concept is no longer sleep-specific. I feel that renaming to just *_MAY_LOSE_VALUE could initially be misinterpreted, so I've further changed the symbols to *_TRANSITORY and *_PERSISTENT to address this. The sysfs interface is modified only to keep consistency with the chardev interface in enforcing persistence for userspace exports.

This is the 4.13.16 stable release

leds: gpio: Allow LED to retain state at shutdown

2017-11-28T04:22:52+00:00

In some systems, such as Baseboard Management Controllers (BMCs), we want to retain the state of LEDs across a reboot of the BMC (whilst the host remains up). Implement support for the retain-state-shutdown devicetree property in leds-gpio.

drivers/fsi: occ: Add in-kernel API

2017-11-28T03:42:10+00:00

Add an in-kernel read/write API with exported functions. This is necessary for other drivers which want to directly interact with the OCC. Also add a child platform device node for the associated hwmon device. OpenBMC-Staging-Count: 2 Signed-off-by: Edward A. James Signed-off-by: Joel Stanley

drivers/fsi: sbefifo: Add in-kernel API

2017-11-28T03:42:09+00:00

Refactor the user interface of the SBEFIFO driver to allow for an in-kernel read/write API. Add exported functions for other drivers to call, and add an include file with those functions. Also parse the device tree for child nodes and create child platform devices accordingly. OpenBMC-Staging-Count: 2 Signed-off-by: Edward A. James Signed-off-by: Joel Stanley

mm/page_alloc.c: broken deferred calculation

2017-11-24T07:35:59+00:00

commit d135e5750205a21a212a19dbb05aeb339e2cbea7 upstream. In reset_deferred_meminit() we determine number of pages that must not be deferred. We initialize pages for at least 2G of memory, but also pages for reserved memory in this node. The reserved memory is determined in this function: memblock_reserved_memory_within(), which operates over physical addresses, and returns size in bytes. However, reset_deferred_meminit() assumes that that this function operates with pfns, and returns page count. The result is that in the best case machine boots slower than expected due to initializing more pages than needed in single thread, and in the worst case panics because fewer than needed pages are initialized early.

netfilter/ipvs: clear ipvs_property flag when SKB net namespace changed

2017-11-24T07:35:55+00:00

[ Upstream commit 2b5ec1a5f9738ee7bf8f5ec0526e75e00362c48f ] When run ipvs in two different network namespace at the same host, and one ipvs transport network traffic to the other network namespace ipvs. 'ipvs_property' flag will make the second ipvs take no effect. So we should clear 'ipvs_property' when SKB network namespace changed.
