2018-03-20ARM: dts: omap4-droid4: Configure uart1 pinsTony Lindgren1-0/+33
These are needed to use the n_gsm driver for TS 27.010 UART multiplexing. Note that support for the OOB wake gpio is still missing so the UART is not yet usable for n_gsm. Signed-off-by: Tony Lindgren <tony@atomide.com>

We have a USB OCHI PHY on port 1 for mdm6600. Port 2 is using transceiverless logic (TLL) for USB EHCI for w3glte modem. Let's also fix the node name to use usb-phy while at it.

2018-03-02ARM: dts: omap4-droid4: add soundcardSebastian Reichel1-0/+78
Add sound support to Motorola Droid 4 using simple-soundcard and CPCAP's audio codec. This does not yet correctly represent the whole audio routing, since McBSP3 is also connected to Bluetooth and MDM6600 modem (and probably also 4G modem). These extra DAI links are not yet supported and have not been tested. Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk> Signed-off-by: Tony Lindgren <tony@atomide.com>

"usb-nop-xceiv" is using the phy binding, but is missing #phy-cells property. This is probably because the binding was the precursor to the phy binding.

2017-08-14ARM: dts: Disable HDMI CEC internal pull-upsTony Lindgren1-1/+1
Devices using an external encoder, ESD protection and level shifter such as tpd12s015 or ip4791cz12 have the CEC pull in the encoder chip. And on var-som-om44, there is external pull up resistor R30. So the internal CEC pull-up resistor needs to be disabled as otherwise the external and internal pull are parallel making the pull value much smaller than intended. This leads into the CEC not working as reported by Hans Verkuil <hverkuil@xs4all.nl>.

Motorola Droid 4 uses a WL1285C, so use proper compatible value.

2017-04-04ARM: dts: omap4-droid4: Stop disabling SRAM and GPMCTony Lindgren1-12/+1
I disabled SRAM and GPMC originally when seeing errors with omap_barriers_init(). But that is no longer happening probably because the memory range is now properly configured to 1021 MB instead of 1024 MB. So let's enable SRAM and GPMC so we get omap_barriers_init() working and can idle the GPMC.

2017-03-28ARM: dts: omap4-droid4: Fix MMC1 card for detect GPIO and regulatorTony Lindgren1-2/+2
There's a typo, it should be GPIO176 and not GPIO106. And it seems I messed up the regulators at some point while trying to figure out what devices the regulators are used. The correct regulator for MMC1 is vwlan2.

Droid 4 has two modems, mdm6600 and w3glte. Both are on the HCI USB controller. Let's add a configuration for the HCI so the modems can be enabled.

2017-03-22ARM: dts: omap4-droid4: Add HDMI supportTony Lindgren1-0/+65
We can get HDMI working as long as the 5V regulator is on. There is probably an encoder chip there too, but so far no idea what it might be. Let's keep the 5V HDMI regulator always enabled for now as otherwise we cannot detect the monitor properly.

Droid 4 has a GPIO line that we can use with CONFIG_POWER_RESET_GPIO.

2017-03-06ARM: dts: omap4-droid4: Add touchscreenTony Lindgren1-0/+36
Droid4's touchscreen can be used with mainline's maxtouch driver. The touchscreen's lower area is used for four soft buttons (KEY_MENU, KEY_HOME, KEY_BACK, KEY_SEARCH), but that does not seem to be currently supported by the mainline kernel. The mxt224 configuration can be saved with "mxt-app" for the kernel to load. It can be saved after the first boot with: # mxt-app -d i2c-dev:1-004a --save /lib/firmware/maxtouch.cfg Where the mxt-app can be found at: https://github.com/atmel-maxtouch/mxt-app The firmware for the droid 4 mxt224 comes with GPLv2 license in the Motorola Linux kernel sources. This firmware can be dumped out with "droid4-touchscreen-firmware" program at: https://github.com/tmlind/droid4-touchscreen-firmware The related LCD patches are still pending, but when merged, the touchscreen can be rotated in X with something like: # xrandr --output DSI-1 --rotate right # xinput set-prop 6 'Coordinate Transformation Matrix' \ 0 1 0 -1 0 1 0 0 1 For now, we rely on a gpio-hog but later on we can add the reset gpio handling to the driver and have it load the maxtouch.cfg and maxtouch.fw on boot.

2017-03-05ARM: dts: Add keypad support for droid 4Tony Lindgren1-0/+75
Let's configure the keypad in a way where it's usable out of the box for Linux console use. We want to have the keyboard usable with Linux console for example when stuck into an initramfs during boot, for when installing a distro. As we need to need to have keys mapped in the user space anyways for some of the keys to match the labels, this non-standard mapping or usability should be OK. Some keys don't match the labels either as they don't follow the PC keyboard style. For example we have "shift + ," produce "<", and "shift + ." produce ">" instead of ";" and ":". So let's follow the standard PC keyboard layout for ctrl, shift and alt keys: Ctrl = what is labeled as shift Alt = what is labeled as SYM Shift = what is lableled as caps lock This way we have Ctrl key for console use. Who knows where they got the caps lock idea.. Probably from some focus group popularity vote or something. For the OK key, let's keep it as the useless KEY_OK unless we can come up with some standard mapping for it we can stick with. We have at least Esc, Delete, Meta, and Page Down keys missing, but none of them seem to be better than others. PC keyboard often has Page Down in that location. Esc would be probably the most usable one when installing a Linux distro but is the opposite of OK. Note that the LCD keys are just touchscreen hot spots, so I'm not sure if the driver or hardware allows setting them up as keys for the console. Anyways, the rest can be mapped in the user space.

Let's add minimal support for droid 4 with MMC and WLAN working. It can be booted with appended dtb using kexec to a state where MMC and WLAN work with currently no support for it's PMIC or display. Note that we are currently using fixed regulators as we don't have support for it's cpcap PMIC. I'll be posting regmap_spi based minimal cpcap patches later on for USB and the debug UART on droid 4 multiplexed with the USB connector.
