Some variants of Samsung Galaxy Core Prime LTE / Grand Prime LTE have a
Samsung S3FWRN5 NFC chip that works quite well with the s3fwrn5 driver
in the Linux NFC subsystem.
The clock setup for the NFC chip is a bit special (although this
seems to be a common approach used for Qualcomm devices with NFC):
The NFC chip has an output GPIO that is asserted whenever the clock
is needed to function properly. On the A3/A5 this is wired up to
PM8916 GPIO2, which is then configured with a special function
(NFC_CLK_REQ or BB_CLK2_REQ).
Enabling the rpmcc RPM_SMD_BB_CLK2_PIN clock will then instruct
PM8916 to automatically enable the clock whenever the NFC chip
requests it. The advantage is that the clock is only enabled when
needed and we don't need to manage it ourselves from the NFC driver.

Most of the Galaxy Grand Prime use backlight drivers controlled with PWM
signal.
To simplify the description, add the backlight with the necessary clk-pwm
to the common dtsi.

Like msm8916-samsung-a3u-eur, the Grand Prime uses a Zinitix BT541
touchscreen. Add it together with the necessary fixed-regulator to the
device tree.

Samsung Galaxy Core Prime and Grand Prime are phones based on MSM8916.
They are similar to the other Samsung devices based on MSM8916 with only a
few minor differences.
This initial commit adds support for:
- fortuna3g (SM-G530H)
- gprimeltecan (SM-G530W)
- grandprimelte (SM-G530FZ)
- rossa (SM-G360G)
The device trees contain initial support with:
- GPIO keys
- Regulator haptic
- SDHCI (internal and external storage)
- USB Device Mode
- UART (on USB connector via the SM5502/SM5504 MUIC)
- WCNSS (WiFi/BT)
- Regulators
- QDSP6 audio
- Speaker/earpiece/headphones/microphones via digital/analog codec in
MSM8916/PM8916
- WWAN Internet via BAM-DMUX
There are different variants of Core Prime and Grand Prime, with some
differences in accelerometer, NFC and panel.
Core Prime and Grand Prime are similar, with some differences in MUIC,
panel and touchscreen.
The common parts are shared in
msm8916-samsung-fortuna-common.dtsi and msm8916-samsung-rossa-common.dtsi
to reduce duplication.
