This series addresses a gigabit Ethernet reliability issue as observed on Apalis TK1 related to a PCIe reset timing violation.
This series is available at http://git.toradex.com/cgit/u-boot-toradex.git/log/?h=for-next Changes in v6: - Use macro AS3722_LDO_CONTROL0_MAX_INDEX instead of the hard-coded number 7 in LDO index check as suggested by Jaehoon Chung. - Updated to latest SPDX style. Changes in v5: - Add Stephen's acked-by. - Updated copyright period to 2016-2018. - Changed error() to pr_err(). - Added a blank line after declarations as warned by patman. - Rebased and resend as series so far never got applied! Changes in v4: - Revert previously missed (struct tegra_pcie_port *) casts as reported by Stephen. Changes in v3: - Stick to struct tegra_pcie_port as suggested by Stephen. - Stick to struct tegra_pcie_port as suggested by Stephen. - Introduce proper CONFIG_APALIS_TK1_PCIE_EVALBOARD_INIT Kconfig option as suggested by Stephen. Changes in v2: - Add Simon's reviewed-by. - New bug fix. - Incorporate Stephen's review feedback by introducing a tegra_pcie_port_index_of_port() function as well as a board-specific reset override function. - Add Simon's reviewed-by.
