The pin configuration for HREF boards with AB8505 was added in
commit 77ad9dfc2c7e ("ARM: ux500: move last AB8505 set-up to DT").
As the commit message notes, it was unused back then and it has
remained so even today, especially considering AB8505 did not have
proper device tree support until recently.
We are now preparing to add support for some Samsung smartphones
that are using AB8505. However, they use different pin configs
because using ste-href-ab8505.dtsi is known to break UART.
There were not many HREFs with AB8505, so at this point it seems
unlikely that we will ever make use of this include. Remove it.

AB8505 is a slightly newer version of AB8500.
Overall it is quite similar, but there are some differences like
the number of GPIOs and regulators. Therefore we need a separate
device tree definition for devices making use of AB8505.
The AB8500-specific nodes were moved out of ste-dbx5x0.dtsi in
commit a46f7c6762d8 ("ARM: dts: ux500: Move ab8500 nodes to ste-ab8500.dtsi").
Add a new "ste-ab8505.dtsi" device tree include in a similar way.
Keep the battery/charging related sub-devices disabled by default
since they require additional configuration to work correctly.

The Samsung Galaxy S III mini (GT-I8190) is a smartphone with Ux500 SoC
released in 2012. Thanks to the great mainline support for Ux500,
it can actually run mainline Linux quite well.
Add a new device tree for it with support for:
- Internal Storage (eMMC)
- External Storage (Micro SD card)
- UART
- GPIO Buttons
- Vibrator
Note that the device tree cannot be booted directly with
the original (Samsung) bootloader. It keeps the L2 cache turned on,
which causes the kernel to hang shortly after decompression.
As a workaround I have created a port of (mainline) U-Boot,
which locks the L2 cache before booting Linux. At the moment it does not
replace the Samsung bootloader, instead we let the original bootloader
load U-Boot as an another (intermediate) bootloader.
Another advantage of this is that U-Boot has proper device tree support,
so we do not need to hardcode the kernel command line in the device tree.

samsung-golden has a InvenSense MPU-6051M IMU that provides an
accelerometer and gyroscope. It seems to be functionally compatible
with MPU-6050 so we can easily enable it by adding the necessary
device tree nodes.

samsung-golden has an Atmel mXT224S touch controller connected to I2C.
It is supported by the existing driver for atmel,maxtouch, so all we
need to do to make it work is to define the necessary device tree nodes.
The atmel_mxt_ts driver does not support controlling regulators yet,
so add regulator-always-on for now to turn on the necessary regulators.

samsung-golden uses a BCM4334 WiFi+BT combo chip, connected to SDIO.
It is supported by the brcmfmac driver in mainline,
so we only need to set up the device tree to make it work correctly.
Note: brcmfmac requires (proprietary) firmware + a device-specific
NVRAM file. Both can be extracted from the stock Android system
used on samsung-golden:
- /system/etc/wifi/bcmdhd_sta.bin_b2 -> /lib/firmware/brcm/brcmfmac4334-sdio.bin
- /system/etc/wifi/nvram_net.txt_GPIO4 -> /lib/firmware/brcm/brcmfmac4334-sdio.samsung,golden.txt
brcmfmac4334-sdio.bin from linux-firmware also seems to work,
but results in occasional errors for some reason.

samsung-golden uses a BCM4334 WiFi+BT combo chip.
The BT part is connected via UART and supported by the hci_bcm
driver in mainline.
Add the necessary device tree changes to make it load correctly.
It requires (seemingly) device-specific firmware that can be
extracted from the stock Android system used on samsung-golden:
- /system/bin/bcm4334.hcd -> /lib/firmware/brcm/BCM4334B0.hcd
On my device, scanning for other Bluetooth devices works just fine,
but for some reason it keeps disconnecting immediately
when attempting to connect to an other device.

The new device tree for samsung-golden depends on some additional
drivers that are not selected in the u8500 defconfig yet:
- Bluetooth: hci_bcm
- WiFi: brcmfmac
- Touchscreen: atmel_mxt_ts
- Vibrator: gpio-vibra
- Sensors: inv_mpu6050 (IMU)

I queued all the DTS changes in the linux-stericsson tree and will
send a pull request for it soon-ish!
Thanks for your hard work Stephan!
