[RFC PATCH 0/4] Quality Improvements for Rockchip-IP PCIe

[RFC PATCH 0/4] Quality Improvements for Rockchip-IP PCIe

[Geraldo Nascimento]

During a 30-day debugging-run fighting quirky PCIe devices on RK3399
some quality improvements began to take form and this is my attempt
at upstreaming it. It will ensure maximum chance of retraining to Gen2
5.0GT/s, on all four lanes and plus if anybody is debugging the PHY
they'll now get real values from TEST_I[3:0] for every TEST_ADDR[4:0]
without risk of locking up kernel like with present broken async
strobe TEST_WRITE.

Geraldo Nascimento (4):
  PCI: pcie-rockchip: add bits for Target Link Speed in LCS_2
  PCI: rockchip-host: Set Target Link Speed before retraining
  phy: rockchip-pcie: enable all four lanes
  phy: rockchip-pcie: adjust read mask and write strobe disable

 drivers/pci/controller/pcie-rockchip-host.c |  4 ++++
 drivers/pci/controller/pcie-rockchip.h      |  3 +++
 drivers/phy/rockchip/phy-rockchip-pcie.c    | 16 +++++++++-------

could you check your settings for sending patches please?

The individual patches of this series did not get "in-reply-to" headers
that would point to this cover-letter. Instead each mail of this
series stands on its own, preventing mail clients from creating a
threaded display of the series.

git-send-email normally does create these needed headers on its own,
so could you check if you have some option enabled that prevents this?

Thanks a lot
Heiko

Hi Heiko,

I had noticed the same, I'll fix this for next submissions, and
thanks for calling me out on this!

Geraldo Nascimento
