Subject: [RFC PATCH 0/6] Support the PCIe for TM2(exynos5433)
Date: Mon, 26 Dec 2016 14:20:23 +0900 [thread overview]
Message-ID: <20161226052029.10552-1-jh80.chung@samsung.com> (raw)
In-Reply-To: CGME20161226052030epcas1p45f543765960d14ccf9cd40c2b9cca84b@epcas1p4.samsung.com
This patchset is for supporting PCIe exynos5433.
TM2(exynos5433) supports the PCIe for WiFi. In driver/pci/host/, there is pci-exynos.c.
But i can't touch anything. The below reasons are why i added the new file.
1. Don't have the exynos5440 TRM
- I can't check anything for exynso5440.
- So i can't touch anything for using PHY generic framework.
2. Can't test the exynos5440 board.
- If used the phy generic framework, can't ensure whether it's working fine or not.
3. There is no maintiain for exynos5440.
- i don't know anywhere pci-exynos5440 is used.
As i know, Bjorn(PCIe Maintainer) agreed about adding the new file.
So i added the new pci-exynos5433 file in driver/pci/host/.
And adds the phy-exynos-pcie.c for using PHY generic framework.
When use the PHY generic framework, controlling pcie is more easier than now.
There are future works,
- Supporting MSI
- If possible, combine the one file to pci-exynos.c
This is based on httt://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux.git (for-next branch)
(Because PCI git repository doesn't snycrhonize yet.)
The below is working messesage
