Subject: [PATCH v2 0/6] arm64: dts: meson-g12: add support for PCIe
Date: Mon, 16 Sep 2019 14:50:16 +0200 [thread overview]
Message-ID: <20190916125022.10754-1-narmstrong@baylibre.com> (raw)
This patchset :
- updates the Amlogic PCI bindings for G12A
- reworks the Amlogic PCIe driver to make use of the
G12a USB3+PCIe Combo PHY instead of directly writing in
the PHY register
- adds the necessary operations to the G12a USB3+PCIe Combo PHY driver
- adds the PCIe Node for G12A, G12B and SM1 SoCs
- adds the commented support for the S922X, A311D and S905D3 based
VIM3 boards.
The VIM3 schematic can be found at [1].
This patchset is dependent on Remi's "Fix reset assertion via gpio descriptor"
patch at [2].
This patchset has been tested in a A311D VIM3 and S905D3 VIM3L using a
128Go TS128GMTE110S NVMe PCIe module.
For indication, here is a bonnie++ run as ext4 formatted on the VIM3:
------Sequential Output------ --Sequential Input- --Random-
-Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks--
Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP
4G 93865 99 312837 96 194487 23 102808 97 415501 21 +++++ +++
and the S905D3 VIM3L version:
------Sequential Output------ --Sequential Input- --Random-
-Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks--
Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP
4G 52144 95 71766 21 47302 10 57078 98 415469 44 +++++ +++
Changes since v1 at [3]:
- Collected Andrew's and Rob's Reviewed-by tags
- Added missing calls to phy_init/phy_exit
- Fixes has_shared_phy handling for MIPI clock
- Add comment in the DT concerning firmware setting the right properties
- Added SM1 Power Domain to PCIe node
