[PATCH v5 0/8] Initial support for Samsung Galaxy Tab 2 series

[Mithil Bavishi]

This series adds initial support for the Samsung Galaxy Tab 2
(samsung-espresso7/10) series of devices. It adds support for 6 variants
(P3100, P3110, P3113, P5100, P5110, P5113). Downstream categorised them
based on 3G and WiFi, but since they use different panel, touch
controllers, batteries, I decided to categorise them based on screen
size as espresso7 and espresso10.

It adds basic functionality for both the models including panel, drm,
sdcard, touchscreen, mmc, wifi, bluetooth, keys, battery, fuel gauge,
pmic, sensors.

[PATCH v5 1/8] ARM: dts: twl6032: Add DTS file for TWL6032 PMIC

[Mithil Bavishi]

Add a dedicated DTS file for the TWL6032 PMIC (Phoenix Lite). Already
has driver support with TWL6030 (Phoenix) since both of them are so
similar, some nodes can be reused from TWL6030 as well

This can be included in the board files like twl6030
Example:
...
&i2c1 {
    twl: twl@48 {
        reg = <0x48>;
        interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
        interrupt-controller;
        interrupt-parent = <&gic>;
    };
};

/include/ "twl6032.dtsi"
...

Used in devices like samsung-espresso, amazon-jem, epson-embt2ws etc

We had the discussion. This should be done via pinctrl irq if possible instead of
specifying WAKEUP_EN here, You had some trouble to understand how it can be done,
and we agreed to add the wakeup functionality as a follow-up concentrating just
on that detail and for now just remove WAKEUP_EN.

still this strange matrix. This is no rotation matrix. Determinant is -1.
Something is strange here, so also the idea in our earlier discussion was to
also postpone it and maybe separately discuss it with iio.

Alright, I misunderstood as keeping it and chaning it next time. I'll
remove it.

Similarly, will remove it for v6.

Best,

I think I may have understood what is to be done.
For example we have 
pinctrl-single,pins = <
	OMAP4_IOPAD(0x0bc, WAKEUP_EN | PIN_INPUT | MUX_MODE3)
>;

for wlan_host_wake, so the change needed to be done is from
interrupt-parent = <&gpio3>;
interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "host-wake";
pinctrl-names = "default";
pinctrl-0 = <&wlan_host_wake>;

to

interrupts-extended = <&gpio3 17 IRQ_TYPE_LEVEL_HIGH>, 
			<&omap4_pmx_core 0x0bc>;
interrupt-names = "host-wake", "wakeup";

and remove the pinctrl?
Similarly for all in the omap4_pmx_core domain (wifi, bt, i2c as the
drivers support it)
No chnages for &omap4_pmx_wkup domain

we still need the pinctrl. Just the WAKEUP_EN flag gets managed via the
pinctrl interrupt handling.

offset is from beginning of padconf area, so from
0x4A10 0040, you can see that from.

In omap4-l4.dtsi:
omap4_pmx_core: pinmux@40 {
                                compatible = "ti,omap4-padconf",
                                             "pinctrl-single";
                                reg = <0x40 0x0196>;


The OMAP4_IOPAD macro handles the offset, so you have
different values there.

just remove the WAKEUP_EN flag from there.

The gpio instance in that domain is always-on anyways, so we do not need
any additional wakeup mechanism there.
