2020-05-01net: rtl8139: Minor cleanup of read_eeprom()Marek Vasut
Rename the function to rtl8139_read_eeprom() to keep the naming consistent, keep the variables sorted in reverse xmas tree. No functional change. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Joe Hershberger <joe.hershberger@ni.com>
2020-05-01net: rtl8139: Rework eeprom_delay() macroMarek Vasut

2020-05-01net: dwc_eth_qos: Prevent DMA from writing updated RX DMA descriptorMarek Vasut
The DMA may attempt to write a DMA descriptor in the ring while it is being updated. By writing the DMA descriptor buffer address to 0, it is assured the DMA will not use such a buffer and the buffer can be updated without any interference.

2020-05-01net: dwc_eth_qos: Invalidate RX packet DMA bufferMarek Vasut
This patch prevents an issue where the RX packet might have been accessed by the CPU, which now has cached data from the packet in the caches and possibly various write buffers, and these data may be evicted from the caches into the DRAM while the buffer is also written by the DMA. By invalidating the buffer after the CPU accessed it and before the DMA populates the buffer, it is assured that the buffer will not be corrupted.

2020-05-01net: dwc_eth_qos: Invalidate RX descriptor before readingMarek Vasut
The current code polls the RX desciptor ring for new packets by reading the RX descriptor status. This works by accident, as the RX descriptors are often in non-cacheable memory. However, the driver does support use of RX descriptors in cacheable memory. This patch adds a missing RX descriptor invalidation, which assures the CPU will read a fresh copy of the RX descriptor instead of a cached one.

2020-05-01net: dwc_eth_qos: Correctly wrap around TX descriptor tail pointerMarek Vasut
This code programs the next descriptor in the TX descriptor ring into the hardware as the last valid TX descriptor. The problem is that if the currenty descriptor is the last one in the array, the code will not wrap around correctly and use TX descriptor 0 again, but instead will use TX descriptor at address right past the TX descriptor ring, which is the first descriptor in the RX ring. Fix this by adding the necessary wrap-around.

2020-05-01net: dwc_eth_qos: Fully rewrite RX descriptor field 3Marek Vasut
The RX descriptor field 3 should contain only OWN and BUF1V bits before being used for receiving data by the DMA engine. However, right now, if the descriptor was already used for receiving data and is being cleared, the field 3 is only modified and the aforementioned two bits are ORRed into the field. This could lead to a residual dirty bits being left in the field 3 from previous transfer, and it generally does. Fully set the field 3 instead to clear those residual dirty bits.

The ROC-RK3328-CC from Firefly and Libre Computer Project is a credit card size development board based on the Rockchip RK3328 SoC, with: - 1/2/4 GB DDR4 DRAM - eMMC connector for optional module - micro SD card slot - 1 x USB 3.0 host port - 2 x USB 2.0 host port - 1 x USB 2.0 OTG port - HDMI video output - TRRS connector with audio and composite video output - gigabit Ethernet - consumer IR receiver - debug UART pins The ROC-RK3328-CC has the enable pin of the SD card power switch tied to GPIO_0_D6. This pin also has the function SDMMC0_PWREN, which is muxed by default. SDMMC0_PWREN is an active high signal controlled by the MMC controller, however the switch enable is active low, and pulled low (enabled) by default to make things work on boot. As such, we need to mux away from SDMMC0_PWREN and use GPIO to enable power to the card. The default GPIO state for the pin is pull-down and input, which doesn't require extra configuration when paired with the external pull-down and active low switch. Deal with this by enabling regulator support in SPL, and setting "u-boot,dm-spl" for the regulator and other device nodes needed for muxing the pin.

2020-04-30spi: sifive: Fix QPP transferJagan Teki
The guessed reason is that the existing logic of filling tx fifo with data, rx fifo with NULL for tx transfer and filling rx fifo with data, tx fifo with NULL for rx transfer is not clear enough to support the Quad Page Program.     SiFive SPI controllers have specific sets of watermark registers and SPI I/O directions bits in order to program SPI controllers clear enough to support all sets of operating modes.     Here is the exact programing sequence that would follow on this patch and tested via SPI-NOR and MMC_SPI.     - set the frame format proto, endian - set the frame format dir, set it for tx and clear it for rx - TX transfer:   fill tx fifo with data.   wait for TX watermark bit to clear. - RX transfer:   fill tx fifo with 0xff.   write nbytes to rx watermark register   wait for rx watermark bit to clear.   read the rx fifo data. So, this patch adopts this program sequence and fixes the existing I/O direction bit.

2020-04-30spi: sifive: Fix format register proto fieldJagan Teki
SiFive SPI controller has a proto bit field in frame format register which would be used to configure the SPI I/O protocol lines used on specific transfer.  Right now the driver is configuring this proto using slave->mode, for all types of transctions. This makes the driver unable to function since the proto needs to configure dynamically for each and every transaction separately at runtime. Now, the controller driver supports per transfer via spi-mem exec_opo, so add the fmt_proto flag and fill the per transfer buswidth so that the controller configures the proto bit at runtime. This patch fixes the SPI controller works with SPI NOR flash on quad read with page program.

2020-04-30spi: sifive: Add spi-mem exec opJagan Teki
SiFive SPI controller is responsible to handle the slave devices like mmc spi and spi nor flash. The controller is designed such a way that it would handle the slave transactions based on the I/O protocol numbers, example if spi nor slave send quad write opcode it has to send alone with I/O protocol number of 4 and if it try to send data it has to send I/O protocol number along with 4 line data. But the current spi-xfer code from spi-mem is combining the opcode and address in a single transaction, so the SPI controller will be unable to identify the I/O protocol number of opcode vs address. So, add the spi-mem exec_op with spi-xfer of opcode, address and data as a separate transaction. This doesn't remove the .xfer of dm_spi_ops since mmc spi will make use of it. Note: This code might have moved to the spi-mem core area once we have done the dedicated tests on other controllers and have real reason to move.
