[PATCH v6 0/8] Initial support for Samsung Galaxy Tab 2 series

[PATCH v6 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 v6 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

According to 

https://www.ti.com/lit/ug/swpu231ap/swpu231ap.pdf
Table 3-327

the gpio1 cntroller is always active. So here the WAKEUP_EN is not
needed at all (so also no additional irq required).

Regards,
Andreas
