Subject: [PATCH v3 0/2] rockchip rk3399 port initialization fixes
Date: Fri, 12 Apr 2024 11:37:19 +0900 [thread overview]
Message-ID: <20240412023721.1049303-1-dlemoal@kernel.org> (raw)
A couple of patches to have the rockchip rk3399 host controller port
initialization follow the PCI specifications around PERST# signal timing
handling.
Changes from v2:
- Use PCIE_T_PVPERL_MS macro in patch 1 (and remove useless comments).
- Split second msleep() addition into patch 2 as suggested by Bjorn.
Changes from v1:
- Add more specification details to the commit message.
- Add missing msleep(100) after PERST# is deasserted.

PCI: rockchip-host: Wait 100ms after reset before starting configuration
