This commit enables the RK3399 HDMI TX, which is very similar to the
one found on the RK3288. As requested by Simon, this splits the HDMI
driver into a SOC-specific portion (rk3399_hdmi.c, rk3288_hdmi.c) and
a common portion (rk_hdmi.c).
Note that the I2C communication for reading the EDID works well with
the default settings, but does not with the alternate settings used on
the RK3288... this configuration aspect is reflected by the driverdata
for the RK3399 driver.
Having some sort of DTS-based configuration for the regulator
dependencies would be nice for the future, but for now we simply use
lists of regulator names (also via driverdata) that we probe.

To prepare for adding the RK3399 VOP driver (which shares most of its
registers and config logic with the RK3228 VOP), this change refactors
the driver and splits the RK3288-specific driver off.
The changes in detail are:
- introduces a data-structure for chip-specific drivers to register
features/callbacks with the common driver: at this time, this is
limited to a callback for setting the pin polarities (between the
VOP and the encoder modules) and a flag to signal 10bit RGB
capability
- refactors the probing of regulators into a helper function that
can take a list of regulator names to probe and autoset
- moves the priv data-structure into a (common) header file to be
used by the chip-specific drivers to provide base addresses to
the common driver
- uses a callback into the chip-specific driver to set pin polarities
(replacing the direct register accesses previously used)
- splits enabling the output (towards an encoder) into a separate
help function withint the common driver

This adds a simple driver for reading the efuse block of the RK3399.
It should be easy enough to add drivers for other devices (e.g. the
RK3328, RK3368, etc.) by passing the device details via driver_data.
Unlike the kernel driver (using the nvmem subsystem), we don't expose
the efuse as multiple named cells, but rather as a linear memory that
can be read using misc_read(...).
The primary use case (as of today) is the generation of a 'serial#'
(and a 'cpuid#') environment variable for the RK3399-Q7 (Puma)
system-on-module.
Note that this adds a debug-only (i.e. only if DEBUG is defined)
command 'rk3399_dump_efuses' that dumps the efuse block's content.
N.B.: The name 'rk3399_dump_efuses' was intentionally chosen to
include a SoC-name (together with a comment in the function) to
remind whoever adds support for additional SoCs that this
function currently makes assumptions regarding the size of the
fuse-box based on the RK3399. The hope is that the function is
adjusted to reflect any changes resulting from generalising the
driver for multiple SoCs and is then renamed.

When the live tree is supported some functions need to change a little.
Add an implementation which is used when not inlining these functions.
Signed-off-by: Simon Glass <sjg@chromium.org>
It is common to read a device-tree property from the node associated with
a device. Add convenience functions to do this so that drivers do not need
to deal with accessing the ofnode from the device.
These functions all start with 'dev_read_' to provide consistent naming
for all functions which read information from a device's device tree node.
These are inlined when using the flat DT to save code size. The live tree
implementation is added in a later commit.

Add functions to access addresses in the device tree. These are brought

Signed-off-by: Simon Glass <sjg@chromium.org>
Since U-Boot supports both a live tree and a flat tree, we need an easy
way to access the tree without worrying about which is currently active.
To support this, U-Boot has the concept of an ofnode, which can refer
either to a live tree node or a flat tree node.
For the live tree, the reference contains a pointer to the node (struct
device_node *) or NULL if the node is invalid. For the flat tree, the
reference contains the node offset or -1 if the node is invalid.
Add a basic set of operations using ofnodes. These are implemented by
using either libfdt functions (in the case of a flat DT reference) or
the live-tree of_...() functions.
Note that it is not possible to have both live and flat references active
at the same time. As soon as the live tree is available, everything in
U-Boot should switch to using that. This avoids confusion and allows us to
assume that the type of a reference is simply based on whether we have a
live tree yet, or not.

Enable CONFIG_DM_MMC_OPS and CONFIG_BLK for all Tegra devices. This moves
Tegra to use driver model fully for MMC.
Signed-off-by: Simon Glass <sjg@chromium.org>
This function is called when the MMC block device is being probed. There
is a recursive call in this function since find_mmc_device() itself can
cause the MMC device to be probed.
Admittedly the MMC device should already be probed, since we would not be
probing its child otherwise, but the current code is unnecessarily
convoluted.
Rewrite this to access the MMC structure directly.
Signed-off-by: Simon Glass <sjg@chromium.org>
When binding a new MMC device, make sure that it has the required
operations. Since for now we still support *not* having the operations
(with CONFIG_DM_MMC_OPS not enabled) it makes sense to add this check.
Signed-off-by: Simon Glass <sjg@chromium.org>
The intention with block devices is that the device number (devnum field
in its descriptor) matches the alias of its parent device. For example,
with:
aliases {
mmc0 = "/sdhci@700b0600";
mmc1 = "/sdhci@700b0400";
}
we expect that the block devices for mmc0 and mmc1 would have device
numbers of 0 and 1 respectively.
Unfortunately this does not currently always happen. If there is another
MMC device earlier in the driver model data structures its block device
will be created first. It will therefore get device number 0 and mmc0
will therefore miss out. In this case the MMC device will have sequence
number 0 but its block device will not.
To avoid this, allow a device to request a device number and bump any
existing device number that is using it. This all happens during the
binding phase so it is safe to change these numbers around. This allows
device numbers to match the aliases in all circumstances.
Add a test to verify the behaviour.

Sometimes it is useful to be able to find a block device without also

It is good practice to include common.h as the first header. This ensures
that required features like the DECLARE_GLOBAL_DATA_PTR macro,
configuration options and common types are available.
Fix up some files which currently don't do this. This is necessary because
driver model will soon start using global data and configuration in the
dm/read.h header file, included via dm.h. The gd->fdt_blob value will be
used to access the device tree and CONFIG options will be used to
determine whether to support inline functions in the header file.

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.

On i.MX, SYSCTL.SDCLKFS may be set to 0 in order to make the SD clock

There is no dedicated reset signal wired up for the MX6QDL thus if the
bootloader enables the link we need some special handling to get the core
back into a state where it is safe to touch it for configuration.
While there has been some special handling in the Linux kernel to do this,
it was removed in 4.11 thus we need to do it properly in the bootloader
and therefore without this if you enable PCI in the bootloader you will hang
while booting the 4.11 kernel.
This puts the PCIe controller back into a safe state for the kernel driver
before launching the kernel.
