[ Upstream commit 88a20edf76091ee7f1bb459b89d714d53f0f8940 ]

The microSD card slot in the Sapphire board is not working because of
several issues:
 1.- The vmmc power supply is missing in the DTS. It is capable of 3.0V
 and has a GPIO-based enable control.
 2.- The vqmmc power supply can provide up to 3.3V, but it is capped in
 the DTS to just 3.0V because of the vmmc capability. This results in a
 conflict from the mmc driver requesting an unsupportable voltage range
 from 3.3V to 3.0V (min > max) as reported in dmesg. So, extend the
 range up to 3.3V. The hw should be able to stand this 0.3V tolerance.
 See mmc_regulator_set_vqmmc in drivers/mmc/core/core.c.
 3.- The card detect signal is non-working. There is a known conflict
 with jtag, but the workaround in drivers/soc/rockchip/grf.c does not
 work. Adding the broken-cd attribute to the DTS fixes the issue.

AM65 has two PCIe controllers and each PCIe controller has '2' address
spaces one within the 4GB address space of the SoC and the other above
the 4GB address space of the SoC (cbass_main) in addition to the
register space. The size of the address space above the 4GB SoC address
space is 4GB. These address ranges will be used by CPU/DMA to access
the PCIe address space. In order to represent the address space above
the 4GB SoC address space and to represent the size of this address
space as 4GB, change address-cells and size-cells of interconnect to 2.

Since OSPI has similar need in MCU Domain Memory Map, change
address-cells and size-cells of cbass_mcu interconnect also to 2.

running at a lower voltage saves power.

power on delay to properly initialize. Datasheet mentions that chip
needs 30 ms to be properly powered on and that it needs some more time
to be initialized.

Fix that by adding 100ms ramp delay to regulator responsible for
powering PHY.

Note that issue was found out and fix tested on pine64-lts, but it's
basically the same as sopine-baseboard, only layout and connectors

The driver shows this message only for the first spurious interrupt
by using WARN_ONCE(). Changing this to WARN() shows, that this is
happening quite frequently (up to once a second).

Since the eMMC 5.1 specification, where CQE and CQHCI are specified,
does not mention that spurious TCN interrupts for DCMDs can be simply
ignored, we must assume that using this feature is not working reliably.

The current implementation uses DCMD for REQ_OP_FLUSH only, and
I could not see any performance/power impact when disabling
this optional feature for RK3399.

Therefore this patch disables DCMDs for RK3399.

[ Upstream commit 924726888f660b2a86382a5dd051ec9ca1b18190 ]

The rk3328-roc-cc board exhibits tx stability issues with large packets,
as does the rock64 board, which was fixed with this patch
https://patchwork.kernel.org/patch/10178969/

A similar patch was merged for the rk3328-roc-cc here
https://patchwork.kernel.org/patch/10804863/
but it doesn't include the tx/rx_delay tweaks, and I find that they
help with an issue where large transfers would bring the ethernet
link down, causing a link reset regularly.

commit 6fd8b9780ec1a49ac46e0aaf8775247205e66231 upstream.

Several rk3328 based boards experience high rgmii tx error rates.
This is due to several pins in the rk3328.dtsi rgmii pinmux that are
missing a defined pull strength setting.
This causes the pinmux driver to default to 2ma (bit mask 00).

These pins are only defined in the rk3328.dtsi, and are not listed in
the rk3328 specification.
The TRM only lists them as "Reserved"
(RK3328 TRM V1.1, 3.3.3 Detail Register Description, GRF_GPIO0B_IOMUX,
GRF_GPIO0C_IOMUX, GRF_GPIO0D_IOMUX).
However, removal of these pins from the rgmii pinmux definition causes
the interface to fail to transmit.

Also, the rgmii tx and rx pins defined in the dtsi are not consistent
with the rk3328 specification, with tx pins currently set to 12ma and
rx pins set to 2ma.

Fix this by setting tx pins to 8ma and the rx pins to 4ma, consistent
with the specification.
Defining the drive strength for the undefined pins eliminated the high
tx packet error rate observed under heavy data transfers.
Aligning the drive strength to the TRM values eliminated the occasional
packet retry errors under iperf3 testing.
This allows much higher data rates with no recorded tx errors.

Tested on the rk3328-roc-cc board.

commit 09f91381fa5de1d44bc323d8bf345f5d57b3d9b5 upstream.

Various rk3328 based boards experience occasional sdmmc0 write errors.
This is due to the rk3328.dtsi tx drive levels being set to 4ma, vs
8ma per the rk3328 datasheet default settings.

Fix this by setting the tx signal pins to 8ma.

Ports are described by child 'port' nodes contained in the device node.
'ports' is optional and is used to group all 'port' nodes which is not
the case here.

commit 8d26c1390aec795d492b8de5e4437751e8805a1d upstream.

This reverts commit abd7d097. This
change was already partially reverted by John Stultz in
commit 9c6d26df ("arm64: dts: hikey: Fix eMMC corruption regression").

This change appears to cause controller resets and block read failures
which prevents successful booting on some hikey boards.

commit 83b944174ad79825ae84a47af1a0354485b24602 upstream.

Somewhere along recent changes to power control of the wl1835, power-on
became very unreliable on the hikey, failing like this:

wl1271_sdio: probe of mmc2:0001:1 failed with error -16
wl1271_sdio: probe of mmc2:0001:2 failed with error -16

After playing with some dt parameters and comparing to other users of
this chip, it turned out we need some power-on delay to make things
stable again. In contrast to those other users which define 200 ms, the
hikey would already be happy with 1 ms. Still, we use the safer 10 ms,
like on the Ultra96.
