The Huawei Ascend G7 supports NFC using the NXP PN547, which is supported by the nxp-nci-i2c driver in mainline. It seems to detect NFC tags using "nfctool" just fine, although it seems like there are not really any useful applications making use of the Linux NFC subsystem. :( Signed-off-by:

The Huawei Ascend G7 is a smartphone from Huawei based on MSM8916. It's fairly similar to the other MSM8916 devices, the only notable exception are the "cd-gpios" for detecting if a SD card was inserted: It looks like Huawei forgot to re-route this to gpio38, so the correct GPIO seems to be gpio56 on this device. Note: The original firmware from Huawei can only boot 32-bit kernels. To boot arm64 kernels it is necessary to flash 64-bit TZ/HYP firmware with EDL, e.g. taken from the DragonBoard 410c. This works because Huawei forgot to set up (firmware) secure boot for some reason. Also note that Huawei no longer provides bootloader unlock codes. This can be bypassed by patching the bootloader from a custom HYP firmware, making it think the bootloader is unlocked. I use a modified version of qhypstub [1], that patches a single instruction in the Huawei bootloader. The device tree contains initial support for the Huawei Ascend G7 with: - UART (untested, probably available via some test points) - eMMC/SD card - Buttons - Notification LED (combination of 3 GPIO LEDs) - Vibrator - WiFi/Bluetooth (WCNSS) - USB [1]: https://github.com/msm8916-mainline/qhypstubSigned-off-by:

This spi flash part is actually being clocked at 37.5MHz, not 25MHz, because of the way the clk driver is rounding up the rate that is requested to the nearest supported frequency. Let's update the frequency here, and remove the TODO because this is the fastest frequency we're going to be able to use here. Reviewed-by:

We don't use the PON module on Trogdor devices. Instead the reboot reason is sort of stored in the 'eventlog' and the bootloader figures out if the boot is abnormal and records that there. Disable the PON node and then drop the power key disabling because that's a child node that will no longer be enabled if the PON node is disabled. Reviewed-by:

On coachz it could be observed that SPI_CLK voltage level was only 1.4V during active transfers because the drive strength was too weak. The line hadn't finished slewing up by the time we started driving it down again. Using a drive strength of 8 lets us achieve the correct voltage level of 1.8V. Though the worst problems were observed on coachz hardware, let's do this across the board for trogdor devices. Scoping other boards shows that this makes the clk line look nicer on them too and doesn't introduce any problems. Only the clk line is adjusted, not any data lines. Because SPI isn't a DDR protocol we only sample the data lines on either rising or falling edges, not both. That means the clk line needs to toggle twice as fast as data lines so having the higher drive strength is more important there. Signed-off-by:

The Samsung Galaxy A3/A5 both 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. Note that for some reason Samsung decided to connect the I2C pins to GPIOs where no hardware I2C bus is available, so we need to fall back to software bit-banging with i2c-gpio.

For now, only add the fuel gauge/battery device to the device tree, so we can check the remaining battery percentage.

The Samsung Galaxy A3/A5 both have two capacitive touch keys, connected to an ABOV MCU. It implements the same interface as implemented by the tm2-touchkey driver and works just fine with the coreriver,tc360-touchkey compatible. It's probably actually some Samsung-specific interface that they implement with different MCUs. Note that for some reason Samsung decided to connect this to GPIOs where no hardware I2C bus is available, so we need to fall back to software bit-banging using i2c-gpio. The vdd/vcc-supply is board-specific and will be added separately for a3u/a5u. Co-developed-by:

As per Dmitry Baryshkov [1]: a) The 2nd "reg" should be 0x3c because "Offset 0x38 is USB3_DP_COM_REVISION_ID3 (not used by the current driver though)." b) The 3rd "reg" "is a serdes region and qmp_v3_dp_serdes_tbl contains registers 0x148 and 0x154." I think because the 3rd "reg" is a serdes region we should just use the same size as the 1st "reg"? [1] https://lore.kernel.org/r/ee5695bb-a603-0dd5-7a7f-695e919b1af1@linaro.orgReviewed-by:

Add the operating points capabilities of the kryo CPUs, that can be used for frequency scaling. There are two differents operating point tables, one for the big cluster and one for the LITTLE cluster.

CoachZ rev3 uses a 100k NTC thermistor for the charger temperatures, instead of the 47k NTC that is stuffed in earlier revisions. Add .dts files for rev3. The 47k NTC currently isn't supported by the PM6150 ADC driver. Disable the charger thermal zone for rev1 and rev2 to avoid the use of bogus temperature values. This also gets rid of the explicit DT files for rev2 and handles rev2 in the rev1 .dts instead. There was some back and forth downstream involving the 'dmic_clk_en' pin, after that was sorted out the DT for rev1 and rev2 is the same. Signed-off-by:
