We need to acquire mutex before using the resources,
and need to release it after finished.
So we don't need to write registers in the blanking period.

* [PATCH v11 03/12] drm/mediatek: add *driver_data for different hardware settings
From: YT Shen @ 2017-01-11 6:51 UTC (permalink / raw)
To: dri-devel, Philipp Zabel, CK Hu
Cc: Mark Rutland, devicetree, srv_heupstream, emil.l.velikov,

yingjoe.chen, linux-arm-kernel
In-Reply-To: <1484117473-46644-1-git-send-email-yt.shen@mediatek.com>
There are some hardware settings changed, between MT8173 & MT2701:
DISP_OVL address offset changed, color format definition changed.
DISP_RDMA fifo size changed.
DISP_COLOR offset changed.
MIPI_TX pll setting changed.
And add prefix for mtk_ddp_main & mtk_ddp_ext & mutex_mod.

* [PATCH v11 00/12] MT2701 DRM support
From: YT Shen @ 2017-01-11 6:51 UTC (permalink / raw)
To: dri-devel, Philipp Zabel, CK Hu
Cc: Mark Rutland, devicetree, srv_heupstream, emil.l.velikov,
linux-kernel, Rob Herring, linux-mediatek, Matthias Brugger,

This is MT2701 DRM support PATCH v10, based on 4.10-rc1.
We add DSI interrupt control, transfer function for MIPI DSI panel support.
Most codes are the same, except some register changed.
For example:
- DISP_OVL address offset changed, color format definition changed.
- DISP_RDMA fifo size changed.
- DISP_COLOR offset changed.
- MIPI_TX setting changed.
We add a new component DDP_COMPONENT_BLS, and the connections are updated.
OVL -> RDMA -> COLOR -> BLS -> DSI
RDMA -> DPI
And we have shadow register support in MT2701.
Changes since v10:
- Add binding descriptions for newly added bindings
- Remove color data pointer from generic mtk_ddp_comp
- Remove "drm/mediatek: add mipi_tx data rate check" from the patch series
- Remove "drm/mediatek: add dsi ulp mode control" from the patch series
- Update descriptions for "drm/mediatek: add non-continuous clock mode and EOT packet control"
- Fix DSI disable flow
Changes since v9:
- Split DSI patches into smaller parts
- Use a real linux errno for return value
- Add error handling in mtk_output_dsi_enable()
- Remove unused changes and redundant delays
- Add helpers and macros for configuration
- Combine "drm/mediatek: rename macros, add chip prefix" and "drm/mediatek: add *driver_data for different hardware setting"
Changes since v8:
- enable 3 DSI interrupts only
- move mtk_dsi_wait_for_irq_done() to the patch of irq control
- use the name BLS in DRM driver part
- move BLS declaration to a separate patch
- update mtk_dsi_switch_to_cmd_mode()
- update mtk_output_dsi_enable() and mtk_output_dsi_disable()
Changes since v7:
- Remove redundant codes
- Move the definition of DDP_COMPONENT_BLS to patch of "drm/mediatek: update display module connections"
- Move _dsi_irq_wait_queue into platform driver data
- Move mtk_dsi_irq_data_clear() to patch of "drm/mediatek: add dsi interrupt control"
- Add more descriptions in the commit messages
Changes since v6:
- Change data type of irq_data to u32
- Rewrite mtk_dsi_host_transfer() for simplify
- Move some MIPI_TX config to patch of "drm/mediatek: add *driver_data for different hardware settings".
- Remove device tree from this patch series
Changes since v5:
- Remove DPI device tree and compatible string
- Use one wait queue to handle interrupt status
- Update the interrupt check flow and DSI_INT_ALL_BITS
- Use same function for host read/write command
- various fixes
Changes since v4:
- Add messages when timeout in mtk_disp_mutex_acquire()
- Add descriptions for DISP_REG_MUTEX registers
- Move connection settings for display modules to a separate patch
- Remove 'mt2701-disp-wdma' because it is unused
- Move cleaning up and renaming to a separate patch
- Use wait_event_interruptible_timeout() to replace polling
- Remove irq_num from mtk_dsi structure
- Remove redundant and debug codes
Changes since v3:
- Add DSI support for MIPI DSI panels
- Update BLS binding to PWM nodes
- Remove ufoe device nodes
- Remove redundant parentheses
- Remove global variable initialization
Changes since v2:
- Rename mtk_ddp_mux_sel to mtk_ddp_sout_sel
- Update mt2701_mtk_ddp_ext components
- Changed to prefix naming
- Reorder the patch series
- Use of_device_get_match_data() to get driver private data
- Use iopoll macros to implement mtk_disp_mutex_acquire()
- Removed empty device tree nodes
Changes since v1:
- Removed BLS bindings and codes, which belong to pwm driver
- Moved mtk_disp_mutex_acquire() just before mtk_crtc_ddp_config()
- Split patch into smaller parts
- Added const keyword to constant structure
- Removed codes for special memory align
Thanks,
yt.shen

It's limited by the vqmmc regulator. Either way the host controller
supports it right?

* [PATCH v8 0/3] Add support for the S6E3HA2 panel on TM2 board
From: Hoegeun Kwon @ 2017-01-11 6:33 UTC (permalink / raw)
To: krzk, robh, thierry.reding, airlied, kgene
Cc: devicetree, linux-samsung-soc, cw00.choi, linux-kernel, dri-devel,
jh80.chung, andi.shyti, Hoegeun Kwon
In-Reply-To: <CGME20170111063407epcas5p2ffdcda0a9ab0e954f1e441c26403290b@epcas5p2.samsung.com>
Purpose of this patch is add support for S6E3HA2 AMOLED panel on
the TM2 board. The first patch adds support for S6E3HA2 panel
device tree document and driver, the second patch add support for
S6E3HA2 panel device tree.
Thank you for your review.
Changes for V8:
- Applied below two patches: (drm/exynos)
: drm/exynos: mic: Add mode_set callback function
: drm/exynos: mic: Fix parse_dt function
- The dt-binding patch and driver patch were divided.
- Rebase these patches on samsung SoC tree[1] and tm2 touckey patch[2].
Change for V7:
- Fixed the mode_set callback function of mic device driver.
because the mic register is initialized when entering suspend
mode, so should set the reg value whenever pre_enable is
called.
Changes for V6:
- Fixed the parse_dt function of dsi device driver.
- Removed OF graph of panel in DT and DT binding document.
- Fixed the s6e3ha2 panel device driver.
- Fixed from number size to ARRAY_SIZE().
- Fixed error handling in mipi_dsi_dcs_* functions.
- Fixed the clock of display_mode.
- Removed unnecessary casting and error log.
Change for V5:
- The V5 has only one fix in V4 below.
- Removed the enable check of the mic driver in mode_set
callback, because mode_set should be performed every time.
Changes for V4:
- Removed display-timings in devicetree, the display-timings has
been fixed to be provided by the device driver.
- Added the mode_set callback function into exynos_drm_mic,
because the exynos_drm_mic driver can not parse a videomode
struct by removing the display-timings from the devicetree.
Changes for V3:
- In the DT binding document, made it clearly that the panel is a
child node of dsi.
- Fix reset-gpio active from high to low.
- Is the OF graph saying related to patch2?
Althogh the panel is a child of dsi, I think OF graph necessary.
because if a remote-endpoint is not specified, the dsi also
panel is not probed.
- The display-timings has been fixed to be provided by the device
driver. however, I think display-timings is necessary in dts.
because if dts does not have display-timings, dsi will not load.
Changes for V2:
- Fixed the samsung,s6e3ha2.txt DT document.
- Added active high or low after the description of the GPIOs.
- Removed the reg and added a description of the virtual
channel number of a DSI peripheral.
Depends on:
[1] https://git.kernel.org/cgit/linux/kernel/git/krzk/linux.git/ (for-next branch)
[2] https://patchwork.kernel.org/patch/9504131/
- ("arm64: dts: exynos: Add tm2 touchkey node")

* [PATCH v3 0/7] power: bq27xxx: add support for NVRAM R/W access
From: Matt Ranostay @ 2017-01-11 6:19 UTC (permalink / raw)
To: linux-pm, devicetree; +Cc: sre, tony, Matt Ranostay
Enable access to the NVRAM for the bq27425 chipset which allows to
update the battery metrics that are used in the state machine.
This allows adjustments of a termination voltage, design energy, and
design voltage.
Changes from v1:
* add documentation for mWh and mAh property units
* change devicetree entries to match new property units
Changes from v2:
* split i2c changes into respective patches
* add documentation for battery information for fuel gauge
* rebased documentation patches on change on the list
* abstracted the battery configuration for the state machine
to an generic struct and platform data access function

This patch adds the device tree support for FSL LS2088A SoC based on
ARMv8 architecture.
Following levels of DTSI/DTS files have been created for the LS2088A
SoC family:
- fsl-ls2088a.dtsi:
DTS-Include file for FSL LS2088A SoC.
- fsl-ls2088a-qds.dts:
DTS file for FSL LS2088A QDS board.
- fsl-ls2088a-rdb.dts:
DTS file for FSL LS2088A RDB board.

Changes for v4:
- Incorporated Shawn's comments by reorganizing
DTSI, moving all include definations to the top
- add missing files
Changes for v2:
- reorganize LS2088A device tree to use common
nodes from LS2080A device trees.

In-Reply-To: <1484114979-4664-1-git-send-email-abhimanyu.saini-3arQi8VN3Tc@public.gmane.org>
LS2088A and LS2080A are similar SoCs with a few differences like
ARM cores etc.
Reorganize the LS2080A device tree to move the common nodes to:
- fsl-ls208xa.dtsi
- fsl-ls208xa-rdb.dtsi
- fsl-ls208xa-qds.dtsi

Changes for v4:
- Incorporated Shawn's comments by reorganizing
DTSI, moving all #include to the top and,
- add missing files
Changes for v3:
- rename dts/dtsi files

* [PATCH v4 0/3] Add QorIQ LS2088A platform support
From: Abhimanyu Saini @ 2017-01-11 6:09 UTC (permalink / raw)

Abhimanyu Saini
This patchset adds support for the QorIQ LS2088A SoC.
LS2088A SoC is similar to LS2080A SoC with a few differences like it has A72 cores.
This patchset
- reorganize LS2088A DTS/DTSI for code reuseability
- adds LS2088A device dtsi and dts files.
Abhimanyu Saini (3):
dt-bindings: Add compatible for LS2088A QDS and RDB board
arm64: dts: freescale: ls2080a: Split devicetree for code resuability
arm64: dts: freescale: ls2088a: Add DTS support for FSL's LS2088A SoC
Changes for v4:
- Incorporated Shawn's comments by reorganizing
DTSI, moving all #include to the top and,
- add missing files
Changes for v3:
- rename dts/dtsi files
Changes for v2:
- reorganize LS2088A device tree to use common
nodes from LS2080A device trees.
- Both LS2080A and LS2088A have same hardware
controllers, so separate dt-binding patches for
pcie, gpio, dspi, qspi are not required.
