-Subject: [PATCH 02/14] ARM: dts: AM33xx: Correct gpio #interrupt-cells
- property
-
-Following commit ff5c9059 and therefore other omap platforms using
-the gpio-omap driver correct the #interrupt-cells property on am33xx
-too. The omap gpio binding documentaion also states that
-the #interrupt-cells property should be 2.

-Subject: [PATCH 334/752] video: da8xx-fb: adding dt support
-
-Enhancing driver to enable probe triggered by a corresponding dt entry.
-
-Add da8xx-fb.txt documentation to devicetree section.
-
-Obtain fb_videomode details for the connected lcd panel using the
-display timing details present in DT.
-
-Ensure that platform data is present before checking whether platform
-callback is present (the one used to control backlight). So far this
-was not an issue as driver was purely non-DT triggered, but now DT
-support has been added this check must be performed.
-
-v2: squashing multiple commits from Afzal Mohammed (afzal@ti.com)
-v3: remove superfluous cast
-v4: expose both ti,am3352-lcdc and ti,da830-lcdc for .compatible
- as driver can use enhanced features of all version of the
- silicon block.
-v5: addressed review comments from Prabhakar Lad
-v6: Changed the .compatible naming to match the existing drm bindings
- for am33xx devices
-v7: clarify which compatible to use in the documentation for DA850

- invocation
-
-Fix defect where SGX is running at half of the expected framerate.
-The original patch (@ commit ID 9a1a810516ae9cb3259b898b6879901c5b44fa90)
-seems to have a mistake where it only calls the callback
-for the even or the odd frames depending on the revision of the LCD controller
-This patch corrects this and invokes the callback for both odd and even frame
-for just the Rev02 version of the LCDC (won't find an SGX GPU on a Rev01).

-With DT bindings to specify which devices should not be idled and reset
-at init being in place, and the corresponding dtsi files for am33xx/omap4
-and omap5 updated using those bindings, we can now clean up hwmod internal
-flags for HWMOD_INIT_NO_RESET and HWMOD_INIT_NO_IDLE which were infact used
-to specify the exact same information.
-
-For GPMC, the HWMOD_INIT_NO_RESET flag seems to be added in hwmod not due to
-any errata around the GPMC IP, but rather because any timings
-set by the bootloader are not being correctly programmed by the kernel.
-This seems like something that needs to be fixed as part of GPMC driver
-in the kernel, and hence the flag is left as is in hwmod, which can be
-removed once the driver does what its expected to.

-Subject: [PATCH 212/752] ASoC: davinci-evm: Add device tree binding
-
-Device tree support for Davinci Machine driver
-
-When the board boots with device tree, the driver will receive card,
-codec, dai interface details (like the card name, DAPM routing map,
-phandle for the audio components described in the dts file, codec mclk
-speed). The card will be set up based on this information. Since the
-routing is provided via DT we can mark the card fully routed so core
-can take care of disconnecting the unused pins.

-
-This patch adds DMA register location to mcasp DT bindings. On am33xx
-SoCs the McASP registers are mapped trough L4 interconnect, which is
-not accessible by the DMA controller, so McASP data port is mapped
-trough L3 to a different location.

-
-Add omap-des driver with platform data for OMAP4. Support added for DES
-ECB and CBC modes.
-
-Where possible, code is reused from omap-aes driver with changes made for
-adjusting key size, block size, removing non-existent encryption modes
-and adding support for OMAP4 platform data and offsets.
-
-Tests have been conducted with the CRYPTO test manager, and functionality
-is verified at different page length alignments.

-Subject: ARM: dts: omap4-panda-es: Do not reset gpio1
-
-Do not reset GPIO1 at boot-up because GPIO 7 in GPIO1 block is used on
-OMAP4460 PandaBoard-ES to select voltage register in TPS62361 which
-supplies VDD_MPU.
-
-Without this, OMAP4460 PandaBoard-ES boards fail to boot-up because
-MPU voltage switches over to VSET0 voltage value (boot voltage) which
-is not sufficient to operate the device at OPP100.

-Subject: ARM: OMAP3+: do not register non-dt OPP tables for device tree boot
-
-OMAP3+ supports both device tree and non-device tree boot.
-Device tree bindings for OMAP3+ is supposed to be added via dts following:
-Documentation/devicetree/bindings/power/opp.txt
-
-Since we now have device tree entries for OMAP3+ cpu OPPs,
-The current code wrongly adds duplicate OPPs. So, dont register OPPs
-when booting using device tree.

-Subject: ARM: OMAP2+: add missing lateinit hook for calling pm late init
-
-AM335x, AM43xx, OMAP5 and DRA7 have missing late init hook. Introduce
-SoC specific hook with a call to OMAP2+ generic lateinit hook. This
-allows the generic late initializations such as cpufreq hooks to be
-active.
-
-Based on out-of-tree patches that need to be introduced in
-mainline, this introduction allows us to provide the foundation for
-further SoC specific features as they are developed.

-When running with DT, we no longer have a board file that can set up the
-platform data for wlcore. Allow this data to be passed from DT.
-
-Since some platforms use a gpio-irq, add support for passing either the
-irq number or the gpio number. For the latter case, the driver will
-request the gpio and convert it to the irq number. If an irq is
-specified, it'll be used as is.
-
-[Arik - the pdev_data pointer does not belong to us and is freed when
-the device is released. Dereference to our private data first.]
