x86: fsp: Replace e-mmc with emmc in devicetree bindings

2020-09-21T08:41:35+00:00

The term eMMC is used inconsistently within the FSP devicetree
bindings (e-mmc and emmc), especially for "emmc-host-max-speed"
documentation and code disagree.

Change all eMMC instances within the FSP bindings to consistently
use "emmc". The term "emmc" is already used a lot within U-Boot,
while "e-mmc" is only used in the FSP bindings.

i2c: add nexell driver

2020-07-29T12:43:40+00:00

Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01:
- i2c/nx_i2c.c: Some adaptions mainly because of changes in
  "struct udevice".
- several Bugfixes in nx_i2c.c.
- the driver has been for s5p6818 only. Code extended appropriately
  in order s5p4418 is also working.
- "probe_chip" added.
- pinctrl-driver/dt is used instead of configuring the i2c I/O-pins
  in the i2c-driver.
- '#ifdef CONFIG...' changed to 'if (IS_ENABLED(CONFIG...))' where
  possible (and similar).
- livetree API (dev_read_...) is used instead of fdt one (fdt...).

msm_gpio: Add support for Qualcomm IPQ40xx

2020-07-29T12:43:40+00:00

Snapdragon SoCs and IPQ40xx use common TLMM IP,
so existing driver supports IPQ40xx as well.

So lets simply add a compatible for IPQ40xx.

msm_serial: Read bit rate register value from DT

2020-07-29T12:43:40+00:00

IPQ40xx and currently supported Snapdragon boards don't use the same one
so enable reading it from DT, if no DT property is found default value
is the same as the previous define.

fsl_dspi: Introduce DT bindings for CS-SCK and SCK-CS delays

2020-07-27T08:46:26+00:00

Communication with some SPI slaves just won't cut it if these delays
(before the beginning, and after the end of a transfer) are not added to
the Chip Select signal.

These are a straight copy from Linux:

sound: Add an ACPI driver for Maxim MAX98357ac

2020-07-17T06:32:24+00:00

This chip is used on coral and we need to generate ACPI tables for sound
to make it work. Add a driver that does just this (i.e. at present does
not actually support playing sound).

dm: core: Add a way of overriding the ACPI device path

Some devices such as GPIO need to override the normal path that would be
generated by driver model. Add a device-tree property for this.
