* Qualcomm platforms >~2016 gain support for the RPMh (Resource Power Manager)
peripheral which is used to control most regulators. The RB5 is now able to
power up its USB VBUS regulator via the rpmh regulator driver. Git history
from the original Linux driver is preserved for ease of maintenance.
* IPQ40xx SoCs gain ethernet networking support via the new ESS EDMA driver.
|
|
This adds the driver for the ESS EDMA ethernet adapter
found inside of Qualcomm IPQ40xx SoC series.
This driver also integrates the built in modified QCA8337N
switch support as they are tightly integrated.

IPQ4019 has more networking related resets that will be required for future
wired networking support, so lets add them.
This syncs the driver with Linux.

A lot of the features in here are only relevant when running
multi-threaded with interrupts. Drop everything except what we need to
run single-threaded with a single TCS (which is all the rpmh-rsc
framework in U-Boot supports).
Keep rpmh_write_async() for simplicity and make it wrap the regular
rpmh_write().

Minor adjustments to fix building with U-Boot and work correctly as a
synchronous driver without interrupts. RPMh is fast enough that we can
get away with just firing off requests and assuming they complete.

Since U-Boot is single threaded, we can avoid most of the complexity
that comes with handling more than one in-flight TCS. Drop all the rpmh
code associated with multi-threading as we'll instead wait for a
response on each TCS.

Keep the header pointer in the .data section so we don't initialize it
again after relocation, adjust cmd_db_get_header() to work with the
U-Boot API, and skip validating the header since all cmd-db users are
children of the rpmh-rsc and those children will only probe if cmd-db
initializes successfully.

Integrate cmd-db into the U-Boot driver model.
This is just a wrapper around an in-memory database, so we just need to
get the address and validate that cmd-db is there.
Since cmd_db_header will be stored in the .data section we can skip
bind if it's already set.

Qualcomm platforms may have drivers that bind to reserved memory nodes
(cmd-db [1] and smem [2]) which are relevant to U-Boot. Include
/reserved-memory in dm_extended_scan() so that these will be handled
correctly.

Add True Random Number Generator (TRNG) driver for Exynos chips. This
implementation is heavily based on Linux kernel's counterpart [1]. It
also follows upstream dt-bindings [2].
TRNG block is usually a part of SSS (Security Sub System) IP-core on
Exynos chips. Because SSS access on Exynos850 is protected by TZPC
(TrustZone Protection Control), it's not possible to read/write TRNG
registers from U-Boot, as it's running in EL1 mode. Instead, the
corresponding SMC calls should be used to make the secure software
running in EL3 mode access it for us. Those SMC calls are handled by
LDFW (Loadable Firmware), which has to be loaded first. For example, for
E850-96 board it's done in its board_init(), so by the time RNG
capabilities are needed the LDFW should be already loaded and TRNG
should be functional.

Enabling CONFIG_CMD_PWM, and consequently CONFIG_DM_PWM, causes the pwm
command to fail due to a missing clock.
=> pwm enable 0 0
Enable clock-controller@20c4000 failed
Failed to enable per_clk
pwm: '0' not found
Command 'pwm' failed: Error -2
Note that it is trivial to also add the clocks for PWM2, PWM3, and PWM4.
However, I only tested PWM1 and thus only added the clock for that
signal.

Commit 727fa4539ca2 ("clk: Add support for I2C clocks on NXP's imx6q SoC
which use CCF") added I2C clocks for I2C1 and I2C2, but not I2C3.
Consequently, devices using I2C3 fail after enabling CONFIG_CLK_IMX6Q
and thus CONFIG_CLK. Therefore, this commit adds the last I2C clock.

The osc_24m is the clock-output-name and not the one that
is used as internal name reference from the strcmp. The clock
that use osc_24m, will not be able to reparent it as they should.
We need anyway register the osc_24m clock fixed factor in the clock
tree.
