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

+TI LCD Controller on DA830/DA850/AM335x SoC's
+
+Required properties:
+- compatible:
+ DA830, DA850 - "ti,da8xx-tilcdc"
+ AM335x SoC's - "ti,am33xx-tilcdc"
+- reg: Address range of lcdc register set
+- interrupts: lcdc interrupt
+- display-timings: typical videomode of lcd panel, represented as child.
+ Refer Documentation/devicetree/bindings/video/display-timing.txt for
+ display timing binding details. If multiple videomodes are mentioned
+ in display timings node, typical videomode has to be mentioned as the
+ native mode or it has to be first child (driver cares only for native
+ videomode).
+
+Recommended properties:
+- ti,hwmods: Name of the hwmod associated to the LCDC
+
+Example for am335x SoC's:
+
+lcdc@4830e000 {

From: Darren Etheridge <detheridge@ti.com>
Date: Mon, 4 Nov 2013 12:27:40 -0600
Subject: [PATCH 752/752] video/da8xx-fb fix defect with vsync callback
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).

The platform_quirk element in the platform data was used to change the
way the IRQ is triggered. When set, the EDGE_IRQ quirk would change
the irqflags used and treat edge trigger differently from the rest.
Instead of hiding this irq flag setting behind the quirk, have the
board files set the flags during initialization. This will be more
meaningful than driver-specific quirks when we switch to DT.
Additionally, fix missing gpio_request() calls in the boarding files
(so that setting the flags actually works).

The pwr_in_suspend flag depends on the MMC settings which can be
retrieved from the SDIO subsystem, so it doesn't need to be part of
the platform data structure. Move it to the platform device data that
is passed from SDIO to wlcore.

Instead of defining an enumeration with the FW specific values for the
different clock rates, use the actual frequency instead. Also add a
boolean to specify whether the clock is XTAL or not.
Change all board files to reflect this.
Additionally, this reverts commit 26f45c (ARM: OMAP2+: Legacy support
for wl12xx when booted with devicetree), since this is not be needed
anymore, now that DT support for WiLink is implemented.

Add refclock and tcxoclock as clock providers in WiLink. These clocks
are not accesible outside the WiLink module, but they are registered
in the clock framework anyway. Only the WiLink chip consumes these
clocks.
In theory, the WiLink chip could be connected to external clocks
instead of using these internal clocks, so make the clock consumer
code generic enough. If external clocks are used, then the internal
clock device tree nodes are not necessary, but the external ones must
be specified.

Read the clock nodes from the device tree and use them to set the
frequency for the refclock and the tcxo clock.
Also, call sdio_set_drvdata() earlier, so the glue is already set in
the driver data when we call wlcore_get_pdata_from_of() and we don't
need to pass it as a parameter.

The fref and the tcxo clocks settings are optional in some platforms.
WiLink8 doesn't need either, so we don't check the values. WiLink 6
only needs the fref clock, so we check that it is valid or return with
an error. WiLink7 needs both clocks, if either is not available we
return with an error.

Add device tree bindings documentation for the TI WiLink modules.
Currently only the WLAN part of the WiLink6, WiLink7 and WiLink8
modules is supported.

In v3, use IRQ_TYPE_LEVEL_HIGH in the example, as suggested by Laurent.

+TI WiLink Wireless Modules Device Tree Bindings
+===============================================
+
+The WiLink modules provide wireless connectivity, such as WLAN,
+Bluetooth, FM and NFC.
+
+There are several different modules available, which can be grouped by
+their generation: WiLink6, WiLink7 and WiLink8. WiLink4 is not
+currently supported with device tree.
+
+Currently, only the WLAN portion of the modules is supported with
+device tree.
+
+Required properties:
+--------------------
+
+- compatible: should be "ti,wilink6", "ti,wilink7" or "ti,wilink8"
+- interrupt-parent: the interrupt controller
+- interrupts: out-of-band WLAN interrupt
+ See the interrupt controller's bindings documentation for
+ detailed definition.
+
+Optional properties:
+--------------------
+
+- clocks: list of clocks needed by the chip as follows:
+
+ refclock: the internal WLAN reference clock frequency (required for
+ WiLink6 and WiLink7; not used for WiLink8).
+
+ tcxoclock: the internal WLAN TCXO clock frequency (required for
+ WiLink7 not used for WiLink6 and WiLink8).
+
+ The clocks must be defined and named accordingly. For example:
+
+ clocks = <&refclock>
+ clock-names = "refclock";
+
+ refclock: refclock {
+ compatible = "ti,wilink-clock";
+ #clock-cells = <0>;
+ clock-frequency = <38400000>;
+ };
+
+ Some modules that contain the WiLink chip provide clocks in the
+ module itself. In this case, we define a "ti,wilink-clock" as shown
+ above. But any other clock could in theory be used, so the proper
+ clock definition should be used.
+
+
+Example:
+--------
+
+Example definition that can be used in OMAP4 Panda:
+
+wlan {
+ compatible = "ti,wilink6";
+ interrupt-parent = <&gpio2>;
+ interrupts = <21 IRQ_TYPE_LEVEL_HIGH>; /* gpio line 53 */
+ clocks = <&refclock>;
+ clock-names = "refclock";
+
+ refclock: refclock {
+ compatible = "ti,wilink-clock";
+ #clock-cells = <0>;
+ clock-frequency = <38400000>;
+ };
+};
