The functions virtio_pci_get_config() and virtio_pci_set_config() don't
take the offset into account when reading the config space. For example
this manifests when U-Boot tries to read the MAC address of the VirtIO
networking device. It reads 6 equa bytes instead of the proper addess.
Fix those functions by taking the offset in the config space into
account.

Fix the driver to behave like the chip datasheet requires.
Improve wake up function to send low signal on SDA line for at least
60us as chip requires to wake up. Fix sleep function to move the chip
into sleep mode, not into idle mode. Remove unnecessary for loop,
which would never run for more than one iteration.
|

The ATSHA204A chip requires SDA line to go low for at least 60us to
wake up the chip. Previous implementation did not meet this requirement
due to the NAK received on bus and not sending the zeroes.
The function to ignore the NAK and send bytes regardless is not
supported in the u-boot making it impossible to wake up the chip
this way.
Instead, the bus speed, if needed, is set to lowest value and the
message is sent to the address 0x0. This way, the address of zero
makes the SDA line go low for about 80us, meeting the required time
to wake up the chip. The zero length packet is not sent by the i2c,
so the one byte is sent to the transfer function, but only the address
is sent anyway.
After sending the zero address, the bus speed is restored to the
previous value if it was slowed down to wake up the chip.

Some previous commit changed the continue statement to return,
making the for loop used to retry waking up the chip to always
return after one iteration. This commit removes the loop, cleaning

- Merge assorted TI K3 platform / SoC updates
|

Apurva Nandan <a-nandan@ti.com> says:
Hello Everyone!
This series will introduce basic support (SD and UART) support for Texas
Instruments J784S4 EVM.
The J784S4 SoC device tree patches are taken from kernel patch submissions
and will be updated as they are accepted and merged to the kernel tree.
All other patches are specific to SPL and u-boot and do not have
dependency on other trees. Appreciate a review for acceptance to u-boot
tree.
Here are some of the salient features of the J784S4 automotive grade
application processor:
The J784S4 SoC belongs to the K3 Multicore SoC architecture
platform, providing advanced system integration in automotive,
ADAS and industrial applications requiring AI at the network edge.
This SoC extends the K3 Jacinto 7 family of SoCs with focus on
raising performance and integration while providing interfaces,
memory architecture and compute performance for multi-sensor, high
concurrency applications.
Some highlights of this SoC are:
* Up to 8 Cortex-A72s, four clusters of lockstep capable dual Cortex-R5F MCUs,
4 C7x floating point vector DSPs with Matrix Multiply Accelerator(MMA) for
deep learning and CNN.
* 3D GPU: Automotive grade IMG BXS-4-64 MC1
* Vision Processing Accelerator (VPAC) with image signal processor and Depth
and Motion Processing Accelerator (DMPAC)
* Three CSI2.0 4L RX plus two CSI2.0 4L TX, two DSI Tx, one eDP/DP and one
DPI interface.
* Integrated gigabit ethernet switch, up to 8 ports (TDA4VH), two ports
support 10Gb USXGMII; Two 4 lane PCIe-GEN3 controllers, USB3.0 Dual-role
device subsystems, Up to 20 MCANs, among other peripherals.
See J784S4 Technical Reference Manual (SPRUJ52 - JUNE 2022)
for further details: http://www.ti.com/lit/zip/spruj52
In addtion, the J784S4 EVM board is designed for TI J784S4 SoC. It
supports the following interfaces:
* 32 GB DDR4 RAM
* x2 Gigabit Ethernet interfaces capable of working in Switch and MAC mode
* x1 Input Audio Jack, x1 Output Audio Jack
* x1 USB2.0 Hub with two Type A host and x1 USB 3.1 Type-C Port
* x2 4L PCIe connector
* x1 UHS-1 capable micro-SD card slot
* 512 Mbit OSPI flash, 1 Gbit Octal NAND flash, 512 Mbit QSPI flash,
UFS flash.
* x6 UART through UART-USB bridge
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs
* 40-pin User Expansion Connector
* x2 ENET Expansion Connector, x1 GESI expander, x2 Display connector
* x1 15-pin CSI header
* x6 MCAN instances

In udma_probe() the return value of setup_resources() is stored in the
u32 "ch_count" member of "struct udma_dev", due to which any negative
return value which indicates an error is masked.
Fix this by storing the return value of setup_resources() in the already
declared integer variable "ret", followed by assigning it to the "ch_count"
member of "struct udma_dev" in case of no error.
While at it, change the "return ret" at the end of udma_probe() to a
"return 0", to explicitly indicate that probe was successful.

Hi,
Rev 2 of the series.
This is a follow up from [1] - Without the 32k crystal configuration,
wlan doesn't work. Debounce is needed for HDMI Hot plug detect(hpd)
gpio interrupt not storming.
At least the 32k configuration has been done for toradex and phytec
boards, follow similar model of programming.
Series is now based off master branch.
Bootlog: https://gist.github.com/nmenon/75df38bee907785d1d78d1ec4abd7304
Changes from V2:
- Removed depedency on [2] - depending on which way
the merge sequence goes, one of the series will need a rebase.
- Added a patch for a bug that Jan noticed
- Fixup for the fat finger missing 0x in 0x4080 :(

We had enabled USB and network pxe boot with the hope to get it all
merged on time. However, it has not panned out. Drop usb and pxe boot
