When setting async EIC as IRQ_TYPE_EDGE_BOTH type, we missed to set the SPRD_EIC_ASYNC_INTMODE register to 0, which means detecting edge signals. Thus this patch fixes the issue.

2019-01-23gpiolib: fix line event timestamps for nested irqsBartosz Golaszewski
Nested interrupts run inside the calling thread's context and the top half handler is never called which means that we never read the timestamp. This issue came up when trying to read line events from a gpiochip using regmap_irq_chip for interrupts. Fix it by reading the timestamp from the irq thread function if it's still 0 by the time the second handler is called.

When multiple instances of pcf857x chips are present, a fix up message [1] is printed during the probe of the 2nd and later instances.

2019-01-23drm/i915/icl: do a posting read after irq installDaniele Ceraolo Spurio
When reading GEN11_GT_INTR_DWx closely after enabling the interrupts in gen11_irq_postinstall, the returned value is garbage. This can cause other parts of the setup code (e.g. gen11_reset_one_iir) to think that there are interrupts to be cleared when there are none. The garbage value is only seen on the first read done after the enable, so this looks like a posting issue. Adding a posting read after enabling the interrupts does indeed fix the problem. Note that the posting read has been purposely added outside of gen11_master_intr_enable since the issue has only been observed when the full interrupt setup is performed.

On a NOP double buffer update where current buffer address is the same as the next buffer address, the SDW_UPDATE bit clears too late. As we are now using this bit to determine when it is safe to signal flip completion to userspace this will delay completion of atomic commits where one plane doesn't change the buffer by a whole frame period. Fix this by remembering the last buffer address and just skip the double buffer update if it would not change the buffer address.

2019-01-22drm/i915: Refactor PSR status debugfsJosé Roberto de Souza
The old debugfs fields was not following a naming partern and it was a bit confusing. So it went from: ~$ sudo more /sys/kernel/debug/dri/0/i915_edp_psr_status Sink_Support: yes PSR mode: PSR1 Enabled: yes Busy frontbuffer bits: 0x000 Main link in standby mode: no HW Enabled & Active bit: yes Source PSR status: 0x24050006 [SRDONACK] To: ~$ sudo more /sys/kernel/debug/dri/0/i915_edp_psr_status Sink support: yes [0x03] PSR mode: PSR1 enabled Source PSR ctl: enabled [0x81f00e26] Source PSR status: IDLE [0x04010006] Busy frontbuffer bits: 0x00000000 The 'Main link in standby mode' was removed as it is not useful but if needed by someone the information is still in the register value of 'Source PSR ctl' inside of the brackets, PSR mode and Enabled was squashed into PSR mode, some renames and reorders and we have this cleaner version. This will also make easy to parse debugfs for IGT tests. v2: Printing sink PSR version with only 2 hex digits as it is a byte Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Suggested-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190117205548.28378-2-jose.souza@intel.com

2019-01-22drm/panel: panel-innolux: set display off in innolux_panel_unprepareHsin-Yi, Wang
Move mipi_dsi_dcs_set_display_off() from innolux_panel_disable() to innolux_panel_unprepare(), so they are consistent with innolux_panel_enable() and innolux_panel_prepare(). This also fixes some mode check and irq timeout issue in MTK dsi code. Since some dsi code (e.g. mtk_dsi) have following call trace: 1. drm_panel_disable(), which calls innolux_panel_disable() 2. switch to cmd mode 3. drm_panel_unprepare(), which calls innolux_panel_unprepare() However, mtk_dsi needs to be in cmd mode to be able to send commands (e.g. mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode()), so we need these functions to be called after the switch to cmd mode happens, i.e. in innolux_panel_unprepare.

2019-01-22writeback: synchronize sync(2) against cgroup writeback membership switchesTejun Heo
sync_inodes_sb() can race against cgwb (cgroup writeback) membership switches and fail to writeback some inodes. For example, if an inode switches to another wb while sync_inodes_sb() is in progress, the new wb might not be visible to bdi_split_work_to_wbs() at all or the inode might jump from a wb which hasn't issued writebacks yet to one which already has. This patch adds backing_dev_info->wb_switch_rwsem to synchronize cgwb switch path against sync_inodes_sb() so that sync_inodes_sb() is guaranteed to see all the target wbs and inodes can't jump wbs to escape syncing. v2: Fixed misplaced rwsem init.

2019-01-22drm/dp: Implement I2C_M_STOP for i2c-over-auxVille Syrjälä
Consult the I2C_M_STOP flag to determine whether to set the MOT bit or not. Makes it possible to send multiple messages in one go with stop+start generated between the messages (as opposed nothing or repstart depending on whether thr address/rw changed).
