[PATCH 2/2] mm: swap: move anonymous THP split logic to vmscan

The add_to_swap aims to allocate swap_space(ie, swap slot and swapcache) so if it fails due to lack of space in case of THP or something(hdd swap but tries THP swapout) *caller* rather than add_to_swap itself should split the THP page and retry it with base page which is more natural. Cc:

[PATCH 1/2] mm: swap: unify swap slot free functions to put_swap_page

[PATCH 3/4] drm/bridge: Add support for the Raspberry Pi 7" Touchscreen.

This driver communicates with the Atmel microcontroller for sequencing the poweron of the TC358762 DSI-DPI bridge and controlling the backlight PWM. The following lines are required in config.txt, to keep the firmware from trying to bash our I2C lines and steal the DSI interrupts:

[PATCH 2/4] dt-bindings: Document the Raspberry Pi Touchscreen nodes.

The Raspberry Pi 7" Touchscreen is a DPI touchscreen panel with DSI->DPI bridge and touchscreen controller integrated, that connects to the Raspberry Pi through its 15-pin "DSI" connector (some lines are DSI, some lines are I2C). This device is represented in the DT as three nodes (DSI device,

[PATCH 1/4] drm/vc4: Adjust modes in DSI to work around the integer PLL divider.

BCM2835's PLLD_DSI1 divider doesn't give us many choices for our pixel clocks, so to support panels on the Raspberry Pi we need to set a higher pixel clock rate than requested and adjust the mode we program to extend out the HFP so that the refresh rate matches. Signed-off-by: Eric Anholt

[PATCH 4/4] drm/panel: Add the Raspberry Pi 7" touchscreen's panel.

The timings are those that the firmware defines as the baseline, which will be modified by the bridge/host as necessary to get the clocking to work. Signed-off-by: Eric Anholt --- drivers/gpu/drm/panel/panel-simple.c | 30 ++ 1 file changed, 30

[PATCH 0/4] Raspberry Pi Touchscreen bridge/panel drivers

Here's the rewrite of the Raspberry Pi display support to split out a bridge driver representing the toshiba+atmel pair. It depends on the panel-bridge layer I've submitted. The RPi DSI stack isn't completely working yet -- I've got some flickery pixels on the display where it seems some color
