[PATCH v2 0/5] Update Microchip PolarFire SoC support
by Padmarao Begari 02 Dec '21

02 Dec '21

This patch set updates Microchip PolarFire SoC Icicle Kit support of RISC-V U-Boot. The patches are based upon latest U-Boot tree (https://source.denx.de/u-boot/u-boot) at commit id 3144ba23bf4649f699078259fdf2e5cb4eab8f53 The device tree split into .dtsi and .dts files, UART1 uses for console instead of UART0, UART0 is reserved for Hart Software Services, common device node for eMMC/SD, add Microchip I2C driver and default build for SBI_V02. Changes in v2: - Fix some typos - Remove Microchip macb compatible string - Add compatible "cdns,macb" at ethernet device node - Update MACB driver to support 32-bit and 64-bit DMA Padmarao Begari (5): net: macb: Remove Microchip compatible string i2c: Add Microchip PolarFire SoC I2C driver riscv: dts: Split Microchip device tree riscv: Update Microchip MPFS Icicle Kit support doc: board: Update Microchip MPFS Icicle Kit doc arch/riscv/dts/microchip-mpfs-icicle-kit.dts | 518 ++++------------ arch/riscv/dts/microchip-mpfs.dtsi | 571 ++++++++++++++++++ board/microchip/mpfs_icicle/Kconfig | 5 + board/microchip/mpfs_icicle/mpfs_icicle.c | 17 +- configs/microchip_mpfs_icicle_defconfig | 1 - doc/board/microchip/mpfs_icicle.rst | 7 +- drivers/i2c/Kconfig | 6 + drivers/i2c/Makefile | 1 + drivers/i2c/i2c-microchip.c | 482 +++++++++++++++ drivers/net/macb.c | 18 +- .../microchip-mpfs-plic.h | 196 ++++++ .../interrupt-controller/riscv-hart.h | 17 + 12 files changed, 1435 insertions(+), 404 deletions(-) create mode 100644 arch/riscv/dts/microchip-mpfs.dtsi create mode 100644 drivers/i2c/i2c-microchip.c create mode 100644 include/dt-bindings/interrupt-controller/microchip-mpfs-plic.h create mode 100644 include/dt-bindings/interrupt-controller/riscv-hart.h -- 2.25.1

[PATCH] net: eth-phy: Handle gpio_request_by_name() return value
by Marek Vasut 02 Dec '21

02 Dec '21

The gpio_request_by_name() returns zero in case of success, however the conditional return value check in gpio_request_by_name() checks only for (ret != -ENOENT) and if the condition is true, returns ret outright. This leads to a situation where successful gpio_request_by_name() return leads to immediate successful eth_phy_of_to_plat() return as well, and to skipped parsing of "reset-assert-us" and "reset-deassert-us", so the PHY driver operates with valid reset GPIO, but with assert/deassert times set to default, which is 0, instead of the values from DT. This breaks PHY reset. Fix this by checking if return value is non-zero and then for this one single allowed non-zero return value, -ENOENT.

[PATCH] net: dwc_eth_qos: Enable clock in probe

Enable DWC IP clock in driver probe, so the MII access is possible even outside of active network transfers. This is particularly useful when using 'mii' or 'mdio' commands to explore PHY state, neither of which works with DWMAC currently due to the disabled clock.

[PATCH] drivers: net: Soft reset felix switch core
by Radu Bulie 02 Dec '21

02 Dec '21

It turns out that in custom designs if the system is reset multiple times in conjunction with a slight increase in external temperature, the felix switch starts to behave in a strange way: packets are no longer received on the ENECT interface connected to the L2switch internal port (the TX side of internal port stops working or the packets do not reach there. It is not very clear where the packets remain blocked. None of the counters points to a disruption in the L2switch) The issue is not reproducible on NXP reference designs. It was observed that by adding the switch core reset, the problem goes aways, even if intensive testing in temperature chambers is applied. The current patch performs soft reset on the switch core to ensure proper operation of the L2switch.

[PATCH V4] clk: clk_versaclock: Add support for versaclock driver
by Adam Ford 01 Dec '21

01 Dec '21

The driver is based on the Versaclock driver from the Linux code, but due differences in the clock API between them, some pieces had to be changed. This driver creates a mux, pfd, pll, and a series of fod ouputs.
