Looks like davinci_emac and cpsw can share some code although the
device registers have a different layout.
At least the code for getting the MAC address using syscon can
be shared by passing the register offset. Let's start with that
and set up a minimal shared cpsw-shared.c.

The shmobile drm driver selects BACKLIGHT_CLASS_DEVICE
as of 0a5a5499ad "drm: shmobile: Add dependency on
BACKLIGHT_CLASS_DEVICE", but that option in turn depends
on BACKLIGHT_LCD_SUPPORT, so we actually have to select
both, or alternatively use 'depends on BACKLIGHT_CLASS_DEVICE'.
Further, the driver uses FB_SH_MOBILE_MERAM if that is
enabled, but this breaks if MERAM is a module while
the DRM driver is built-in. To solve this, add a dependency
on "FB_SH_MOBILE_MERAM || !FB_SH_MOBILE_MERAM", which forces
DRM_SHMOBILE to be a module if FB_SH_MOBILE_MERAM set to 'm'.

- step detector (generates an iio event at every step the user takes)
- activity recognition (rest, walking, jogging, running)
- speed

- distance
To get accurate pedometer results, the user's height, weight and gender

functions that shall be called from the low level init.
The data format used in this file has two possible evolution paths;
it can either be removed completely once no longer needed, or it will

The get_config() functions for ddi and dp_mst, used to read the value
of cpu_transcoder from the crtc->config instead of the state passed as
an argument. On the hardware state readout path, that happens to work
since the proper value is written to it before encoder->get_config() is
called. However, in the check_crtc() path, the state will be read from
the cpu_transcoder in the software tracking, instead of the one just
read out from hw. Using the field in the supplied intel_crtc_state
should do the right thing in both cases.

Since commit e9f2cefb0c ("usb: phy: generic: migrate to gpio_desc") a
kernel hang is observed on imx51-babbage board:
[ 1.392824] ci_hdrc ci_hdrc.1: doesn't support gadget
[ 1.397975] ci_hdrc ci_hdrc.1: EHCI Host Controller
[ 1.403205] ci_hdrc ci_hdrc.1: new USB bus registered, assigned bus number 1
[ 1.422335] ci_hdrc ci_hdrc.1: USB 2.0 started, EHCI 1.00
[ 1.432962] hub 1-0:1.0: USB hub found
[ 1.437119] hub 1-0:1.0: 1 port detected
This hang happens because the reset GPIO stays at logic level 0.
The USB PHY reset gpio is defined in the dts file as:
reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>;
, which means it is active low, so what the gpio reset pin needs to do in this
case is the following:
- Go to logic level 0 to reset the USB PHY
- Stay at 0 for a bit
- Go back to logic level 1
When switching to gpiod API we need to following according to
Documentation/gpio/consumer.txt:
"The first thing a driver must do with a GPIO is setting its direction. If no
direction-setting flags have been given to gpiod_get*(), this is done by
invoking one of the gpiod_direction_*() functions:
int gpiod_direction_input(struct gpio_desc *desc)
int gpiod_direction_output(struct gpio_desc *desc, int value)"
Since no direction-setting flags have been given to devm_gpiod_get_optional()
in our case, we need to use gpiod_direction_output to comply with the gpiod API.
With this change the USB PHY reset performs a proper reset, the kernel boots
fine and USB host is functional.
